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 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

Points to Remember Respiratory

• Oxygen is essential for life. So, before all else, keep airways open and ease breathing effort.
• Clients with chronic lung disease use more oxygen and energy to breathe. This can create a vicious cycle in which the client works harder, and continually requires more oxygen and more energy.
• Nursing interventions for clients with chronic lung disease should include pacing of activities, because these clients have little reserve for exertion.
• Quality of life for clients can be significantly improved if clients routinely use diaphragmatic breathing and pursed-lip breathing.
• Clients with asthma must understand the different types of inhalers and when to use each type. Some rescue inhalers are for acute dyspnea. Other inhalers are for maintenance or preventative types of drugs.

• A finger or pulse oximeter reading is simply one element of an assessment. It is not the whole picture.
• Cyanosis, a late finding, is determined by oxygenation and hemoglobin content.
• Clients with anemia may be severely hypoxemic and never turn blue, but rather "ashen".
• Clients with polycythemia may be cyanotic with adequate tissue oxygenation.
• The serious public health issue of pulmonary TB requires control and reporting of any incidence and recent contacts that the client had so prophalactic therapy for two to three months can be initiated.
• When caring for a client after a chest tube insertion, an occlusive dressing is placed around the chest tube insertion site and the connections of the chest tube system are taped to prevent air leaks at connections. An occlusive dressing is one that is totally covered, as well as the edges with non-porous tape. This dressing is typically not changed and not expected to have any drainage on it.

• When caring for a client on a ventilator, if an alarm sounds, first, assess the client. See if the alarm resets or if the cause is obvious. If the alarm continues to sound and the client develops distress, disconnect the client from the ventilator, use a manual resuscitation bag to ventilate with 100% oxygen and page or call the respiratory therapist immediately.
• If the ventilator tube disconnects, the low pressure alarm will sound.
• If the high pressure alarm sounds on the ventilator, the nurse should check for some type of obstruction or occlusion of the airway: mucous plugs, biting of the tube by the client, tube slips into right main stem bronchus, or increased secretions.
• To maximize therapeutic effect of inhalers, the key is technique. It is critical to teach clients the right technique and observe how well they use the inhaler.
• Smoking cessation is critical to reduce the risk and severity of lung disease. Second-hand smoke enhances the risk of children to develop asthma or other chronic lung diseases.
• Best approach to pulmonary embolus is prevention. The use of intermittent compression stockings prevents clots in the deep veins.
• Clients with pulmonary TB need intensive community follow up to ensure that they continue with pharmacological treatment once discharged from the hospital. Clients who stop therapy too soon are the source for the more deadly multi-drug resistant forms of pulmonary TB.

iii. tracheotomy/tracheostomy
D. Pharyngitis
1. Inflammation of mucous membranes of pharynx
2. Bacterial, viral, environmental causes
3. Treat findings; if culture shows bacteria, use antibiotics
E. Tonsillitis
1. Inflammation and/or infection of tonsils
2. Acute form is usually bacterial
3. Treat findings; if culture shows bacteria, use antibiotics
F. Peritonsillar abscess
1. Complication of acute tonsillitis
2. Infection spreads to surrounding tissue
3. If swelling is massive, can endanger airway
4. Treat findings; if culture shows bacteria, use antibiotics
G. Vocal cord disorders
1. Laryngitis
a. inflammation of vocal cords and surrounding mucous membranes
b. cause: something irritates the larynx
c. occurs in viral and bacterial infections
d. in children, called croup (larynx blocked by edema, spasm or both)
e. treat findings, rest voice, remove irritants, gargle with warm salt water
2. Vocal cord paralysis
a. injury, trauma or disease of larynx, laryngeal nerves or vagus nerve
b. may result as a complication after thyroidectomy surgery
c. assess how well client can protect airway
d. can sometimes be surgically treated with Teflon injection
H. Cancer of the larynx

b. chemotherapy
c. surgery: removal of all or part of larynx to treat cancer
i. total laryngectomy: no voice, permanent stoma in neck with no risk of aspiration from oral cavity
ii. radical neck dissection: when cancer has metastasized to surrounding tissues
4. Nursing interventions
a. arrange for clients with larnygectomies to meet with members of support groups
b. establish a method for communication before surgery
c. maintain airway; have suction equipment at bedside
d. observe for signs of hemorrhage or infection
e. teach about trach and stoma care
f. assist with period of grieving

COPD

Chronic Obstructive Pulmonary Disease’s pathology is increase resistance of Air Flow from Chronic Bronchitis and Emphysema.The risk are smoking and immunologic.The diagnostic test are PFT, ABG,CBC.The cardinal signs are Blue Bloater (chronic bronchitis) and Pink Puffer (emphysema).Drug of choice is Atrovent which is a bronchodilator and low flow Oxygen. Teach client pursed lip breathing.

Cystic Fibrosis

Cystic Fibrosis is autosomal recessive, lack of protein to transport chloride leading to excessive absorption of water and sodium leading to thick viscous mucous.The risk of it is genetic.The diagnostic exam is Sweat Chloride Test.The cardinal signs are delayed G& D, frequent respiratory infection,Right CHF, Vitamin K deficiency.The drug of choice is Dornase to hydrolyze the DNA in the sputum.The primary concern is hydration.
