a) put color on rails in going upstairs
b) provide high toilet seat
c) provide soft mattress
d) apply restraints to reduce tremors

48. Michael suddenly went into seizures. To protect a child from injury the nurse should:

a) retrain the child's arm and legs
b) place a tongue blade in the child's mouth
c) place a pillow under the child's head
d) provide a waterproof pad for the bed

49. The first nursing priority when providing nursing care for Michael is to:

a) administer antibiotic as ordered as soon as possible
b) keep the room quiet and dim
c) explain all the procedures to the patients
d) begin low-flow oxygen per mask

50. Which room should the nurse assign to Ashley?

b) room 206 with Rica, age one who had pneumonia
c) room 210 with Jack age 2 who has cerebral palsy
d) room 214 with no roommate




NCLEX Secrets - Neurology Board Review:
ANSWERS AND RATIONALE

46) A, C, E, F
- increased ICP is characterized by headache, nausea and vomiting, diplopia, increased systolic BP, slow respiration, slow bounding pulse, widening of pulse pressure, hyperthermia/hypothermia, altered LOC, papilledema, lateralizing sign.

47) B
- the client with Parkinson's disease experiences stiffness/rigidity due to inadequate dopamine production. Dopamine is a neurotransmitter that promotes muscle relaxation. High toilet seat facilitates the client's ability to sit during elimination.

48) C
- the child should never be restrained during a seizure because such action by the nurse can cause fracture of the bones. Tongue blade must not be inserted when the child is already having a seizure because of the risk of injury. Placing waterproof pad at this time is no longer advisable. It is correct to slip pillow under the head to protect the head of the child from banging on any hard object.

49) A
- the priority is to treat the patient with antibiotics at the soonest time possible because the longer the disease goes on without treatment, the greater the risk of seizures and of permanent neurologic damage, such as hearing loss, brain damage, blindness, loss of speech, learning disabilities and behavior problems. Non-neurologic complications may include kidney and adrenal gland failure. Bacterial infections of the central nervous system progress quickly. Within hours of the onset of symptoms, the disease can lead to shock and death.

50) D
- Bacterial meningitis is a highly contagious. Therefore the patient must be placed in a private room to prevent transmitting it to other patients. Nurses who will be in contact with patients with meningitis should wear mask, the mask should be discarded right away when it gets moist or wet. The different types of bacterial meningitis are:
  • Pneumococcus - this bacterium is the most common cause of meningitis in adults and children. It most often occurs when the bacterium Streptococcus pneumoniae (pneumococcus), the same bacterium that causes pneumonia and ear infections, enters the bloodstream and migrates to the brain and spinal cord. Mode of transmission is the same as pneumonia: droplet, direct contact and through respiratory discharges.
  • Meningococcus - this bacterium is another common cause of meningitis in children under age 5, in teens and in young adults. Meningococcal meningitis commonly occurs when bloodstream. It's highly contagious and may cause localized epidemics in college dormitories, boarding schools and on military bases. Five strains of the Neisseria meningitidis bacterium cause meningococcal meningitis. Mode of transmission is by direct contact and respiratory droplets. This type of meningitis is communicable until the meningococci are no longer present from nose and mouth. Prophylactic treatment is Rifampicin taken for 4 days at a dose of 20 mg/kg/day.
  • Haemophilus - the Haemophilus influenzae (H. influenzae) bacterium is the leading cause of bacterial meningitis in children under age 5. The use of the Hib vaccine prevents this type of meningitis. When it occurs, it tends to follow an upper respiratory infection, ear infection (otitis media) or sinusitis. Mode of transmission is by droplet infection and discharges from nose and throat during the infectious period. This type of meningitis is no longer communicable 48 hours after starting antibiotic therapy.

    ANSWERS AND RATIONALE

    6) D
    - hypotension causes headache and dizziness. Angioedema (swelling of face and hands) may also occur as side effect of capoten.

    7) A
    - gentle, smooth ROM exercises promote well-being of the client; prevent stiffness of joints, and contractures. Exercises should be done in a manner that prevents increase in ICP.

    8) Decerebration
    - is abnormal extension. It indicates brainstem function impairment.

    9) C
    - Bell's palsy is paralysis of the facial nerve (CN VII). It is characterized by asymmetry of the face with ptosis of the eyelid on the affected eye.

    10) A
    - high paCO2 level in the blood causes respiratory acidosis. In Guillain-Barre Syndrome, there is weakness/paralysis of respiratory muscles. This causes carbon dioxide retention.

    Situation: Warren was admitted to the hospital with a diagnosis of hypertension.

    1. The nurse should carefully evaluate the pulse prior to administering which medication?

    a) clonidine (catapres)
    b) propanolol (inderal)
    c) atorvastitin calcium (lipitor)
    d) lovastatin (mevinolin)

    2. At the time of Warren's physical examination, which finding was indicative of hypertension?

    a) pupil changes an opthalmoscopic exam
    b) presence of the second heart sound
    c) sinus rhythm on auscultation
    d) cardiac electrocardiogram

    3. When teaching Warren on precautions to take while on antihypertensive medication, the nurse should advice him to:

    a) avoid changing position suddenly
    b) observe for black and blue marks
    c) learn to take his blood pressure TID
    d) take the drugs always on empty stomach

    4. Warren has renal damage related to his hypertensive condition. When teaching him about his diet the nurse should advice him to:

    a) replace whole milk with milk products
    b) use salt substitute such as potassium chloride
    c) eliminate protein from his diet
    d) limit processed foods to fruits and juices

    5. Which test should you order for Warren before treatment is indicated?

    a) creatinine clearance
    b) serum uric acid
    c) serum creatinine
    d) resting electrocardiogram

    ANSWERS AND RATIONALE

    1) B
    - Propanolol is a drug that is used for angina pectoris, MI, arrythmias, hypertension, migraine, essential tremor, pheochromocytoma. Its main effect is to block catecholamine effect in heart and blood pressure, thereby, lowering BP and heart rate. The main potential adverse effect of the drug is bradycardia, heart failure, and hypotension. Thus it is very important to always check the patient's apical pulse and blood pressure before administering the drug. If the patient has bradycardia (below 60), withhold giving the drug and notify physician.
    • always give with food to increase absorption
    • advise not to discontinue abruptly as it can exacerbate angina and precipitate MI
    • advise to continue taking the drug even he is already feeling well
    • this drug should not be given to patients with asthma
    • do not discontinue before surgery for pheochromocytoma
    Clonidine (Catapres) is an antihypertensive drug. Although it affects both blood pressure and pulse rate so that these vital signs must be checked before administering catapres, its effect on heart rate is not as much as that of propanolol. If the patient has hypotension and bradycardia, the drug should not be given and the doctor notified.
    • clonidene may cause a weakly positive Coomb's test and decreases excretion of vanilymandelic acid
    • avoid giving with propanolol and betablockers as it results in rebound hypertension
    • avoid giving with Verapamil as it may cause AV block and severe hypotension
    • avoid giving with herbal supplement capsicum as it may reduce antihypertensive effect of catapres
    • avoid orthostatic hypotension by rising slowly and changing position slowly
    • side effect drowsiness will diminish after 4 to 6 weeks
    • the last dose should be taken immediately before going to bed
    • advise not to discontinue drug abruptly as it may cause rebound hypertension
    Lipitor and lovastatin are drugs used to lower LDL and total cholesterol and triglyceride levels.

    2) A
    - letters b,c,d are examinations and findings that are more often carried out and associated with disease conditions of the heart.
    Hypertension is a persistent systolic blood pressure greater than 140 mmHg and a diastolic pressure greater than 90 mmHg. It is characterized by elevated peripheral vascular resistance from constriction of arterioles, which may be caused by sympathetic responses and stimulation of the renin angiotensin mechanism.
    It is classified as primary or essential hypertension in which there is no known etiology, and secondary, which develops as a result of some other condition.
    On Physical Examination:
    • opthalmoscopic exam: the eyes will usually reveal narrowed arterioles, hemorrhage, exudates and papilledema or swelling of the optic nerve
    • apical and peripheral pulses
    • vital signs and BP
    • edema of extremities
    Patients may complain of:
    • headache at the back of the head and neck
    • nocturia
    • confusion
    • nausea and vomiting
    • visual disturbances
    3) A
    - the most common side effect of antihypertensive drugs is orthostatic hypotension. To prevent it, instruct the patient to avoid changing position suddenly and standing for prolonged periods of time. Advise patient to sit down if he feels dizzy.

    4) D
    - hypertensive patients without renal damage are often placed on a fat/cholesterol, low sodium and low calorie diet.
    Processed, preserved and fast foods are often high in sodium and must be avoided in a low sodium diet
    Proteins are not eliminated in the diet but its intake is limited to the recommended daily allowance to prevent overloading the kidney, adding calories and weight gain.
    Using salt substitutes that contain potassium may interact with the antihypertensive drugs being taken by the patient, especially when patient is taking ACE inhibitors as it may result in hyperkalemia.

    5) C
    - the purpose of the diagnostic tests is to identify possible causes of hypertension and to identify the organs already affected by the disorder in order to institute the most effective treatment regimen for the patient. The routine laboratory tests conducted before initiating treatment include CBC, urinalysis and blood chemistry including glucose, electrolytes, cholesterol, serum creatinine and blood urea nitrogen.
    Serum creatinine and blood urea nitrogen reflect renal function. Hypertension can significantly decrease blood supply to the kidney which can damage the renal system and impair kidney function resulting in fluid retention and inability of the kidney to regulate electrolytes balance and excrete metabolic waste products such as urea. Hematocrit and hemoglobin are monitored as they reflect changes in fluid volume.
