Their use may lead to physical or psychological dependence. Fundamentals of Nursing Schedule III drugs, such as paregoric and butabarbital (Butisol), have a lower abuse potential than Schedule I or II drugs. Abuse of Schedule III drugs may lead to moderate or low physical or psychological dependence, or both. Fundamentals of Nursing Schedule IV drugs, such as chloral hydrate, have a low abuse potential compared with Schedule III drugs. Fundamentals of Nursing Schedule V drugs, such as cough syrups that contain codeine, have the lowest abuse potential of the controlled substances. Fundamentals of Nursing Activities of daily living are actions that the patient must perform every day to provide self-care and interact with society. Fundamentals of Nursing Testing of the six cardinal fields of gaze evaluates the function of all extraocular muscles and cranial nerves III, IV, and VI. Fundamentals of Nursing The six types of heart murmurs are graded from 1 to 6. A grade 6 heart murmur can be heard with stethoscope slightly raised from the chest. Fundamentals of Nursing The most important goal to include in a care plan is the patient’s goal. Fundamentals of Nursing Fruits are high in fiber and low in protein and should be omitted from a low-residue diet. Fundamentals of Nursing The nurse should use an objective scale to assess and quantify pain because postoperative pain varies greatly among individuals. Fundamentals of Nursing Postmortem care includes cleaning and preparing the deceased patient for family viewing, arranging transportation to the morgue or funeral home, and determining the disposition of belongings. Fundamentals of Nursing The nurse should provide honest answers to the patient’s questions. Fundamentals of Nursing Milk shouldn’t be included in a clear liquid diet. Fundamentals of Nursing Consistency in nursing personnel is paramount when caring for a child, and infant, or a confused patient. Fundamentals of Nursing The hypothalamus secretes vasopressin and oxytocin, which are stored in the pituitary gland. Fundamentals of Nursing The three membranes that enclose that brain and spinal cord are the dura mater, pia mater, and arachnoid. Fundamentals of Nursing A nasogastric tube is used to remove fluid and gas from the small intestine preoperatively or postoperatively. Fundamentals of Nursing Psychologists, physical therapists, and chiropractors aren’t authorized to write prescriptions for medication. Fundamentals of Nursing The area around a stoma should be cleaned with mild soap and water. Fundamentals of Nursing Vegetables have a high fiber content. Fundamentals of Nursing The nurse should use a tuberculin syringe to administer an S.C. injection of less than 1 ml. Fundamentals of Nursing For adults, S.C. injections require a 25G 1" needle; for infants, children, elderly, or very thin patients, they require a 25G to 27G ½" needle. Fundamentals of Nursing Before administering medication, the nurse should identify the patient by checking the identification band and asking the patient to state his name. Fundamentals of Nursing To clean the skin before an injection, the nurse should use a sterile alcohol swab and wipe from the center of the site outward in a circular motion. Fundamentals of Nursing The nurse always should inject heparin deep into S.C. tissue at a 90-degree angle (perpendicular to the skin) to prevent skin irritation. Fundamentals of Nursing If blood is aspirated into the syringe before an I.M. injection, the nurse should withdraw the needle, prepare another syringe, and repeat the procedure. Fundamentals of Nursing The nurse shouldn’t cut the patient’s hair without written consent from the patient or an appropriate relative. Fundamentals of Nursing If bleeding occurs after an injection, the nurse should apply pressure until the bleeding stops; if bruising occurs, the nurse should monitor the site for an enlarging hematoma. Fundamentals of Nursing When providing hair and scalp care, the nurse should begin combing at the end of the hair and work toward the head. Fundamentals of Nursing Frequency of patient hair care depends on the length and texture of the hair, duration of hospitalization, and patient’s condition. Fundamentals of Nursing Proper hearing aid function requires careful handling during insertion and removal, regular cleaning of the ear piece to prevent wax buildup, and prompt replacement of dead batteries. Fundamentals of Nursing The hearing aid marked with a blue dot is for the left ear; the one with the red dot is for the right ear. Fundamentals of Nursing A hearing aid shouldn’t be exposed to heat or humidity and shouldn’t be immersed in water. Fundamentals of Nursing The nurse should instruct a patient not to use hair spray while wearing a hearing aid. Fundamentals of Nursing The five branches of pharmacology are pharmacokinetics, pharmacodynamics, pharmacotherapeutics, toxicology, and pharmacognosy. Fundamentals of Nursing The nurse should remove heel protectors every 8 hours to inspect the foot for signs of skin breakdown. Fundamentals of Nursing The purpose of heat application is to promote vasodilation, which reduces pain caused by inflammation. Fundamentals of Nursing A sutured surgical incision is an example of healing by first intention (healing directly, without granulation). Fundamentals of Nursing Healing by secondary intention (healing by granulation) is closure of the wound by the granulation tissue filling the defect and allowing reepithelialization to occur, beginning at the wound edges and continuing to the center, until the entire wound is covered. Fundamentals of Nursing Keloid formation is an abnormality in healing characterized by overgrowth of scar tissue at the wound site. Fundamentals of Nursing The nurse should administer procaine penicillin by deep I.M. injection in the upper outer portion of the buttocks in the adult or in the midlateral thigh in the child. The nurse shouldn’t massage the injection site. Fundamentals of Nursing The ascending colostomy drains fluid feces; the descending colostomy drains solid fecal matter. Fundamentals of Nursing A folded towel (called a scrotal bridge) can provide scrotal support for the patient with scrotal edema caused by vasectomy, epididymitis, or orchitis. Fundamentals of Nursing When giving an injection to the patient with a bleeding disorder, the nurse should use a small-gauge needle and apply pressure to the site for 5 minutes after the injection. Fundamentals of Nursing Platelets are the smallest and most fragile formed element of the blood and are essential for coagulation. Fundamentals of Nursing To insert a nasogastric tube, the nurse should first instruct the patient to tilt the head back slightly and then insert the tube. When the tube is felt curving at the pharynx, the nurse should tell the patient to tilt the head forward to close the trachea and open the esophagus by swallowing. (Sips of water can facilitate this action.) Fundamentals of Nursing According to families whose loved ones are in intensive care units, their four most important needs are to have questions answered honestly, to be assured that the best possible car is being provided, to know the prognosis, and to feel there is hope. Fundamentals of Nursing A double-bind communication when the verbal message contradicts the nonverbal message and the receiver is unsure of which message to respond to. Fundamentals of Nursing A nonjudgmental attitude displayed by the nurse demonstrates that she neither approves nor disapproves of the patient. Fundamentals of Nursing Target symptoms are those that the patient and others find most distressing. Fundamentals of Nursing Advise the patient to take aspirin on an empty stomach with a full glass of water and to avoid foods with acid such as coffee, citrus fruits, and cola. Fundamentals of Nursing For every patient problem, there is a nursing diagnosis; for every nursing diagnosis, there is a goal; and for every goal, there are interventions designed to make the goal a reality. The keys to answering examination questions correctly are identifying the problem presented, formulating a goal for that specific problem, and then selecting the intervention from the choices provided that will enable the patient to reach that goal. Fundamentals of Nursing Fidelity means loyalty and can be shown as a commitment to the profession of nursing and to the patient. Fundamentals of Nursing Giving an I.M. injection against the patient’s will and without legal authority is battery. Fundamentals of Nursing An example of a third-party payor is an insurance company. Fundamentals of Nursing On-call medication should be given within 5 minutes of receipt of the call. Fundamentals of Nursing Generally, the best method to determine the cultural or spiritual needs of the patient is to ask him. Fundamentals of Nursing An incident report shouldn’t be made part of the patient’s record but is an in-house document for the purpose of correcting the problem. Fundamentals of Nursing Critical pathways are a multidisciplinary guideline for patient care. Fundamentals of Nursing When prioritizing nursing diagnoses, use this hierarchy: (1) problems associated with airway, (2) those concerning breathing, and (3) those related to circulation. Fundamentals of Nursing The two nursing diagnoses with the highest priority that the nurse can assign are Ineffective airway clearance and Ineffective breathing pattern. Fundamentals of Nursing A subjective sign that a sitz bath has been effective is that patient expresses a decrease in pain or discomfort. Fundamentals of Nursing For the nursing diagnosis Diversional activity deficit to be valid, the patient must make the statement that he’s “bored, there is nothing to do” or words to that effect. Fundamentals of Nursing The most appropriate nursing diagnosis for an individual who doesn’t speak English is Communication, impaired, related to inability to speak dominant language (English). Fundamentals of Nursing The family of the patient who has been diagnosed as hearing impaired should be instructed to face the individual when they speak to him. Fundamentals of Nursing Up to age 3, the pinna should be pulled down and back to straighten the eustachian tube before instilling medication. Fundamentals of Nursing When administering eyedrops, the nurse should waste the first drop and instill the medication in the lower conjunctival sac to prevent injury to the cornea. Fundamentals of Nursing When administering eye ointment, the nurse should waste the first bead of medication and then apply the medication from the inner to the outer canthus. Fundamentals of Nursing When removing gloves and mask, the gloves, which most likely contain pathogens and are soiled, should be removed first. Fundamentals of Nursing Crutches should placed 6" (15 cm) in front of the patient and 6" to the side to assume a tripod position. Fundamentals of Nursing Listening is the most effective communication technique. Fundamentals of Nursing Process recording is a method of evaluating one’s communication effectiveness. Fundamentals of Nursing When feeding the elderly, limit high-carbohydrate foods because of the risk of glucose intolerance. Fundamentals of Nursing Passive range of motion maintains joint mobility whereas resistive exercises increase muscle mass. Fundamentals of Nursing Isometric exercises are performed on an extremity in a cast. Fundamentals of Nursing A back rub is an example of the gate-control theory of pain. Fundamentals of Nursing Anything below the waist is considered unsterile, a sterile field becomes unsterile when it comes in contact with nay unsterile item, a sterile field must be continuously monitored, and the 1" (2.5 cm) border around a sterile field is considered unsterile. Fundamentals of Nursing A “shift to the left” is evident when there is an increase in immature cells (bands) in the blood to fight an infection. Fundamentals of Nursing A “shift to the right” is evident when there is an increase in mature cells in the blood as seen in advanced liver diseases and pernicious anemia. Fundamentals of Nursing Before administering preoperative medication, make sure that an informed consent form has been signed and attached to the patient’s record. Fundamentals of Nursing The nurse should spend no more than 30 minutes per 8-hour shift in providing care to the patient with a radiation implant. Fundamentals of Nursing The nurse should stand near the patient’s shoulders for cervical implants and at the foot of the bed for head and neck implants. Fundamentals of Nursing The nurse should never be assigned to care for more than one patient with radiation implants. Fundamentals of Nursing Long-handled forceps and a lead-lined container should be in the room of the patient who has a radiation implant. Fundamentals of Nursing Generally, patients who have the same infection and are in strict isolation can share the same room. Fundamentals of Nursing Diseases requiring strict isolation include chickenpox, diphtheria, and viral hemorrhagic fever such as Marburg virus disease. Fundamentals of Nursing For the patient abiding by Jewish custom, milk and meat shouldn’t be served in the same meal. Fundamentals of Nursing Whether the patient can perform a procedure (psychomotor domain of learning) is a better indicator of the effectiveness of patient teaching than whether the patient can simply state the steps of the procedure (cognitive domain of learning). Fundamentals of Nursing Developmental stages according to Erik Erikson are trust versus mistrust (birth to 18 months), autonomy versus shame and doubt (18 months to 3 years), initiative versus guilt (3 to 5 years), industry versus inferiority (5 to 12 years), identity versus identity diffusion (12 to 18 years), intimacy versus isolation (18 to 25 years), generativity versus stagnation (25 to 60 years), and ego integrity versus despair (older than 60 years). Fundamentals of Nursing Face the hearing impaired patient when communicating with him. Fundamentals of Nursing A proper nursing intervention for the spouse of the patient who has suffered a serious incapacitating disease is to assist him in mobilizing a support system. Fundamentals of Nursing Hyperpyrexia refers to extreme elevation in temperature above 106º F (41.1º C). Fundamentals of Nursing

Diabetes Mellitus

* A group of metabolic diseases characterized by elevated levels of glucose in the blood resulting from defects in insulin secretion, insulin action, insulin receptors or any combination of conditions.
* A chronic disorder of impaired glucose metabolism, protein and fat metabolism

BASIC PATHOLOGY : Insulin problem (deficiency or impaired action)
* Insulin is a hormone secreted by the BETA cells of the pancreas
* Stimulus of insulin- HYPERGLYCEMIA
* Action of insulin: it promotes entry of Glucose into the body cells by binding to the insulin receptor in the cell membrane

Insulin Metabolic Functions:
* 1. Transports and metabolizes GLUCOSE
* 2. Promotes GLYCOGENESIS
* 3. Promotes GLYCOLYSIS
* 4. Enhances LIPOGENESIS
* 5. Accelerates PROTEIN SYNTHESIS

RISK FACTORS for Diabetes Mellitus
* 1. Family History of diabetes
* 2. Obesity
* 3. Race/Ethnicity
* 4. Age of more than 45
* 5. Previously unidentified IFG/IGT
* 6. Hypertension
* 7. Hyperlipidemia
* 8. History of Gestational Diabetes Mellitus

CLASSIFICATION OF DM

1. Type 1 DM
* Insulin dependent Diabetes Mellitus
2. Type 2 DM
* Non-insulin dependent Diabetes Mellitus
3. Gestational DM
* Diabetes Mellitus diagnosed during pregnancy
4. DM associated with other conditions or syndromes

Other types of DM
* 1. Impaired Glucose Tolerance
* 2. Impaired Fasting Glucose
* 3. Pre-diabetes

TYPE 1- Diabetes Mellitus

This type of DM is characterized by the destruction of the pancreatic beta cells

Etiology:
1. Genetic susceptibility- HLA DR3 and DR4
2. Autoimmune response
3. Toxins, unidentified viruses and environmental factors

PATHOPHYSIOLOGY
* Destruction of BETA cells--> decreased insulin production --> uncontrolled glucose production by the liver--> hyperglycemia --> signs and symptoms

CLASSIC P’s
* Polyuria
* Polydipsia
* Polyphagia

TYPE 2- Diabetes Mellitus
* A type of DM characterized by insulin resistance and impaired insulin production

Etiology:
1. Unknown
2. Probably genetic and obesity

PATHOPHYSIOLOGY
* Decreased sensitivity of insulin receptor to insulin --> less uptake of glucose --> HYPERGLYCEMIA
* Decreased insulin production --> diminished insulin action --> hyperglycemia --> signs and symptoms
* BUT (+) insulin in small amount --> prevent breakdown of fats --> DKA is unusual

GESTATIONAL Diabetes Mellitus
* Any degree of glucose intolerance with its onset during pregnancy
* Usually detected between 24-28th week gestation
* Blood glucose returns to normal after delivery of the infant
* NEVER administer ORAL HYPOGLYCEMIC AGENTS to PREGNANT MOTHERS!

ASSESSMENT FINDINGS
* 1. Classic 3 P’s
* 2. Fatigue
* 3. Body weakness
* 4. Visual changes
* 5. Slow wound healing
* 6. Recurrent skin and mucus membrane infections

DIAGNOSTIC TESTS
* 1. FBS- > 126
* 2. RBS- >200
* 3. OGTT- > 200
* 4. HgbA1- for monitoring!!
* 5. Urine glucose
* 6. Urine ketones

DIAGNOSTIC CRITERIA
* 1. FBS equal to or greater than 126 mg/dL (7.0mmol/L)
* (Normal 8 hour FBS- 80-109 mg/dL)
* 2. OGTT value 1 and 2 hours post-prandial equal to or greater than 200 mg/dL
* Normal OGTT 1 and 2 hours post-prandial- is
* 140 mg/dL
* 3. RBS of equal to or greater than 200 mg/dL PLUS the 3 P’s

NURSING MANAGEMENT OF DM
* The main goal is to NORMALIZE insulin activity and blood glucose level by:

Nutritional modification
2. Regular Exercise
3. Regular Glucose Monitoring
4. Drug therapy
5. Client Education

The Patient with DM
* HISTORY
* Symptoms and characteristics
* PHYSICAL EXAMINATION
* VS, BMI, Fundoscopy, and Neuro assessment
* LABORATORY EXAMINATION
* FBS, RBS, HgbA1c, lipid profile, ECG, and Urinalysis
* REFERRALS
* Ophthalmologist, Podiatrist, Dietician, etc..

DM Nutritional management

* 1.Review the patient’s diet history to identify eating habits and lifestyle
* 2. Coordinate with the dietician in meal planning for weight loss
* 3. Plan for the caloric intake distributed as follows- CHO 50-60%; Fats 20-30%; and Proteins 10-20%
* 4. Advise moderation in alcohol intake
* 5. Using artificial sweeteners is acceptable

DM Exercise management
* 1. Teach that exercise can lower the blood glucose level
* 2. Diabetics must first control the glucose level before initiating exercise programs.
* 3. Offer extra food /calories before engaging in exercise
* 4. Offer snacks at the end of the exercise period if patient is on insulin treatment.
* 5. Advise that exercise should be done at the same time every day, preferably when blood glucose levels are at their peak
* Regular exercise, not sporadic exercise, should be encouraged.
* 7. For most patient, WALKING is the safe and beneficial form of exercise

Glucose Self Monitoring
* Self-monitoring of blood glucose (SMBG) enables the patient to adjust the treatment regimen to obtain optimal glucose control
* Most common method involves obtaining a drop of capillary blood applied to a test strip.
* The usual recommended frequency is TWO-FOUR times a day.
When is it done?
* At the peak action time of the medication to evaluate the need for adjustments.
* To evaluate BASAL insulin --> test before meals
* To titrate bolus or regular and lispro--> test 2 hours after meals.
* To evaluate the glucose level of those taking ORAL hypoglycemics --> test before and two hours after meals.

Diabetes Mellitus Monitoring therapy
* Testing the glycosylated hemoglobin (HbA1c)
* This glycosylated hemoglobin refers to the blood test that reflects the average blood glucose over a period of TWO to THREE months.
* Normal value is 4 to 6 %
* No patient preparation is needed for this testing
* Done to monitor therapy

Diabetes Mellitus
* Urine testing for glucose
* Benedict’s test
* Urine testing for ketones
* Ketones are by-products of fat breakdown
* Urine testing for ketones
* This is performed whenever TYPE 1 DM have glucosuria or persistent elevation of blood glucose, during illness, and in gestational diabetes

DM Drug therapy

DRUG THERAPY and MANAGEMENT
* Usually, this type of management is employed if diet modification and exercise cannot control the blood glucose level.
* Because the patient with TYPE 1 DM cannot produce insulin, exogenous insulin must be administered for life.
* TYPE 2 DM may have decreased insulin production, ORAL agents that stimulate insulin production are usually employed.

PHARMACOLOGIC INSULIN
* This may be grouped into several categories according to:
1. Source- Human, pig, or cow
2. Onset of action- Rapid-acting, short-acting, intermediate-acting, long-acting and very long acting

* This may be grouped into several categories according to:
3. Pure or mixed concentration
4. Manufacturer of drug

GENERALITIES
* 1. Human insulin preparations have a shorter duration of action than animal source
* 2. Animal sources of insulin have animal proteins that may trigger allergic reaction and they may stimulate antibody production that may bind the insulin, slowing the action
* 3. ONLY Regular insulin can be used INTRAVENOUSLY!
* 4. Insulin are measured in INTERNATIONAL UNITS or “iu”
* 5. There is a specified insulin injection calibrated in units

RAPID ACTING INSULIN
* Lispro (Humalog) and Insulin Aspart (Novolog)
* Produces a more rapid effect and with a shorter duration than any other insulin preparation
* ONSET- 5-15 minutes
* PEAK- 1 hour
* DURATION- 3 hours
* Instruct patient to eat within 5 to 15 minutes after injection

REGULAR INSULIN
* Also called Short-acting insulin
* “R”
* Usually Clear solution administered 30 minutes before a meal
* ONSET- 30 minutes to 1 hour
* PEAK- 2 to 3 hours
* DURATION- 4 to 6 hours

INTERMEDIATE ACTING INSULIN
* Called “NPH” or “LENTE”
* Appears white and cloudy
* ONSET- 2-4 hours
* PEAK- 4 to 6-12 hours
* DURATION- 16-20 hours

LONG- ACTING INSULIN
* “UltraLENTE”
* Referred to as “peakless” insulin
* ONSET- 6-8 hours
* PEAK- 12-16 hours
* DURATION- 20-30 hours

HEALTH TEACHING
Regarding Insulin SELF- Administration
* 1. Insulin is administered at home subcutaneously
* 2. Cloudy insulin should be thoroughly mixed by gently inverting the vial or ROLLING between the hands
* 3. Insulin NOT IN USE should be stored in the refrigerator, BUT avoid freezing/extreme temperature
* 4. Insulin IN USE should be kept at room temperature to reduce local irritation at the injection site
* 5. INSULIN may be kept at room temperature up to 1 month
* 6. Select syringes that match the insulin concentration.
* U-100 means 100 units per mL
* Instruct the client to draw up the REGULAR (clear) Insulin FIRST before drawing the intermediate acting (cloudy) insulin
* 8. Pre-filled syringes can be prepared and should be kept in the refrigerator with the needle in the UPRIGHT position to avoid clogging the needle
* 9. The four main areas for insulin injection are- ABDOMEN, UPPER ARMS, THIGHS and HIPS
* Insulin is absorbed fastest in the abdomen and slowest in the hips
* Instruct the client to rotate the areas of injection, but exhaust all available sites in one area first before moving into another area.
* 10. Alcohol may not be used to cleanse the skin
* 11. Utilize the subcutaneous injection technique- commonly, a 45-90 degree angle.
* 12. No need to instruct for aspirating the needle
* 13. Properly discard the syringe after use.

T-I-E
Test blood--> Inject insulin --> Eat food

COMPLICATIONS OF INSULIN THERAPY

1. LOCAL ALLERGIC REACTIONS
* Redness, swelling, tenderness and induration appearing 1-2 hours after injection
* Usually occurs in the beginning stage of therapy
1. Local allergic reactions
* Disappears with continued use
* Antihistamine can be given 1 hour before injection time
* Porcine and bovine insulin preparations have a higher tendency to produce this reaction.

2. SYSTEMIC ALLERGIC REACTIONS
* Very rare
* Generalized urticaria is the manifestation
* Treatment is desensitization

3. INSULIN DYSTROPHY
* A localized reaction in the form of lipoatrophy or lipohypertrophy
* Lipoatrophy- loss of subcutaneous fat usually caused by the utilization of animal insulin
* Lipohypertrophy- development of fibrofatty masses, usually caused by repeated use of injection site

4. INSULIN RESISTANCE
* Most commonly caused by OBESITY
* Defined as daily insulin requirement of more than 200 units
* Management- Steroids and use of more concentrated insulin

5. MORNING HYPERGLYCEMIA
* Elevated blood sugar upon arising in the morning
* Caused by insufficient level of insulin
* DAWN phenomenon
* SOMOGYI effect
* INSULIN WANING

DAWN PHENOMENON
* Relatively normal blood glucose until about 3 am, when the glucose level begins to RISE
* Results from the nightly surges of GROWTH HORMONE secretion
* Management: Bedtime injection of NPH

SOMOGYI EFFECT
* Normal or elevated blood glucose at bedtime, decrease blood glucose at 2-3 am due to hypoglycemic levels and a subsequent increase in blood glucose (rebound hypergycemia)

* Nocturnal hypoglycemia followed by rebound hyperglycemia
* Due to the production of counter regulatory hormones- glucagon. cortisol and epinephrine
* Management- decrease evening dose of NPH or increase bedtime snack

INSULIN WANING
* Progressive rise in blood glucose from bedtime to morning
* Seen when the NPH evening dose is administered before dinner
* Management: Move the insulin injection to bedtime

ORAL HYPOGLYCEMIC AGENTS
* These may be effective when used in TYPE 2 DM that cannot be treated with diet and exercise
* These are NEVER used in pregnancy!
* There are several agents:
* Sulfonylureas
* Biguanides
* Alpha-glucosidase inhibitors
* Thiazolidinediones
* Meglitinides

SULFONYLUREAS
* MOA- stimulates the beta cells of the pancreas to secrete insulin
* Classified as to generations- first and second generations
* FIRST GENERATION- Acetoheximide, Chlorpropamide, Tolazamide and Tolbutamide
* SECOND GENERATION- Glipizide, Glyburide, Glibenclamide, Glimepiride
* The most common side –effects of these medications are Gastro-intestinal upset and dermatologic reactions.
* HYPOGLYCEMIA is also a very important side-effect
* Chlorpropamide has a very long duration of action. This also produces a disulfiram-like reaction when taken with alcohol
* Second generation drugs have shorter duration with metabolism in the kidney and liver and are the choice for elderly patients

BIGUANIDES- “ Formin”
* MOA- Facilitate the action of insulin on the peripheral receptors
* These can only be used in the presence of insulin
* They have no effect on the beta cells of the pancreas
* Metformin (Glucophage) and Phenformin are examples
* The most important side effect is LACTIC ACIDOSIS!
* These are not given to patient with renal impairment
* These drugs are usually given with a sulfonylurea to enhance the glucose-lowering effect more than the use of each drug individually

ALPHA-GLUCOSIDASE INHIBITORS
* MOA- Delay the absorption of glucose in the GIT
* Result is a lower post-prandial blood glucose level
* They do not affect insulin secretion or action!
* Side-effect: DIARRHEA and FLATULENCE

* Examples of AGI are Acarbose and Miglitol
* They are not absorbed systemically and are very safe
* They can be used alone or in combination with other OHA
* Side-effect if used with other drug is HYPOGLYCEMIA
* Note that sucrose absorption is impaired and IV glucose is the therapy for the hypoglycemia

THIAZOLIDINEDIONES
* MOA- Enhance insulin action at the receptor site
* They do not stimulate insulin secretion
* Examples- Rosiglitazone, Pioglitazone
* These drugs affect LIVER FUNCTION
* Can cause resumption of OVULATION in peri-menopausal anovulatory women

MEGLITINIDES
* MOA- Stimulate the secretion of insulin by the beta cells
* Examples- Repaglinide and Nateglinide
* They have a shorter duration and fast action
* Should be taken BEFORE meals to stimulate the release of insulin from the pancreas
* Principal side-effect of meglitinides- hypoglycemia
* Can be used alone or in combination

ACUTE COMPLICATIONS OF DM
* Hypoglycemia

* 4. Teach patient to refrain from eating high-calorie, high-fat desserts

* 5. Advise in-between snacks, especially when physical activity is increased
* 6. Teach the importance of compliance to medications

Diabetic Ketoacidosis
* This is cause by the absence of insulin leading to fat breakdown and production of ketone bodies
* Three main clinical features:
* 1. HYPERGLYCEMIA
* 2. DEHYDRATION & electrolyte loss
* 3. ACIDOSIS

PATHOPHYSIOLOGY
* No insulin--> reduced glucose breakdown and increased liver glucose production --> Hyperglycemia
* Hyperglycemia--> kidney attempts to excrete glucose --> increased osmotic load --> diuresis --> Dehydration

DIABETIC NEPHROPATHY
* Progressive deterioration of kidney function

DIABETIC NEPHROPATHY
* HYPERGLYCEMIA--> causes the kidney filtration mechanism to be stressed --> blood proteins leak into the urine
* Pressure in the kidney blood vessels increases--> stimulate the development of nephropathy

ASSESSMENT findings for diabetic nephropathy
* 1. Albuminuria
* 2. Anemia
* 3. Acidosis
* 4. Fluid volume overload
* 5. Oliguria
* 6. Hypertension
* 7. UTI

NURSING MANAGEMENT
1. Assist in the control of hypertension- use of ACE inhibitor
2. Provide a low sodium and low protein diet
3. Administer prescribed medication for UTI
4. Assist in dialysis
5. Prepare patient for renal transplantation, if indicated
Diabetic Neuropathy
* A group of disorders that affect all type of nerves including the peripheral, autonomic and spinal nerves

* Two most common types of Diabetic Neuropathy are sensori-motor polyneuropathy and autonomic neuropathy

ASSESSMENT findings
* 1. paresthesias- prickling, tingling or heightened sensation
* 2. decreased proprioception
* 3. decreased sensation of light touch
* 4. unsteady gait
* 5. decreased tendon reflexes

Nursing Management
* 1. Provide teaching that good glucose control is very important to prevent its development
* 2. Manage the pain by analgesics, antidepressants and nerve stimulation

Autonomic Neuropathy- ASSESSMENT findings
* 1. Silent, painless ischemia
* 2. delayed gastric emptying
* 3. orthostatic hypotension
* 4. N/V and bloating sensation
* 5. urinary retention
* 6. sexual dysfunction

Autonomic Neuropathy-Nursing management
* 1. Educate about the avoidance of strenuous physical activity
* 2. Stress the importance of good glucose control to delay the development
* 3. Provide LOW-fat, small frequent feedings
* 4. Administer bulk-forming laxatives for diabetic diarrhea
* 5. Provide HIGH-fiber diet for diabetic constipation

RISK FACTORS for the development of foot and leg ulcers
* 1. More than 10 years diabetic
* 2. Age of more than 40
* 3. Smoking
* 4. Anatomic deformities
* 5. History of previous leg ulcers or amputation

MANAGEMENT of Foot Ulcers
* Teach patient proper care of the foot
* Daily assessment of the foot
* Use of mirror to inspect the bottom
* Inspect the surface of shoes for any rough spots or foreign objects
* Properly dry the feet
* Instruct to wear closed-toe shoes that fit well, recommend use of low-heeled shoes
* Instruct patient NEVER to walk barefoot, never to use heating pads, open-toed shoes and soaking feet
* Trim toenails STRAIGHT ACROSS and file sharp corners
* Instruct to avoid smoking and over-the counter medications and home remedies for foot problems

INSULIN

Types of Insulin

1. Rapid Acting Insulin- Ex. Insulin Lispro ( Humalog)
2. Short Acting Insulin- Ex. Regular Insulin (Humulin R)
3. Intermediate Acting Insulin Ex. NPH Insulin ( Humulin N)
4. Long Acting Insulin- Ex. Insulin Glergene ( Lantus), InsulinDetermir
( Levemir)
5. Fixed Combination of N and R- Ex. 70/30%- 70% N, 30 % R
6. Fixed Combination- Ex. Humalog Mix 75/25, 75% lispro protamine,
25% lispro insulin

Insulin
