years to control her Stage II hypertension. Her blood pressure (BP) at this visit
is 168/96. She is currently complaining of pain on her right hip and on both
knees. She has increased her dose of ibuprofen (Motrin) from 400 mg 3
times day (TID) to 800 mg TID. She is still in pain and would like something
stronger. Which of the following statements is the best explanation of the
effects of ibuprofen (Motrin) on her disease?
A) It increases the chances of adverse effects to her health
B) It inhibits the effect of renal prostaglandins and blunts the effectiveness
of the diuretic
C) It prolongs the therapeutic effects of hydrochlorothiazide and other
diuret- ics
D) None of the statements are true
Answer> It inhibits the effect of renal prostaglandins and blunts the
effectiveness of the diuretic.
NSAIDs and ASA inhibit the vasodilatory effects of prostaglandins, which
predispos- es the kidney to ischemia. NSAIDs and diuretics can cause acute
prerenal failure by decreasing renal blood flow.
2. A 28-year-old student is seen in the school health clinic with complaints
of a hacking cough that is productive of small amounts of sputum and a
runny nose. He does not take any medications, denies any allergies, and
,has no significant medical history. Physical examination reveals a low-grade
temperature of 99.9 degrees Fahrenheit, respirations of 16/min, a pulse of
90 beats per minute, and diffuse fine crackles in the base of the lungs. A
chest radiograph (x-ray) shows diffuse infiltrates on the lower lobe of the
right lung. The total white blood cell count is 10,500/uL. What is the most
likely diagnosis?
A) Streptococcal pneumonia
B) Mycoplasma pneumonia
C) Acute bronchitis
D) Legionnaires disease
Answer> Mycoplasma pneumonia
Mycoplasma pneumonia is the organism most com- monly seen in children
and young adults. It is easily spread from droplets, from sneezing and
coughing, in close proximity. Diagnosis is based on symptoms and x-ray
results of infiltrates in lower lobes.
,3. Which of the following antihypertensive medications should the nurse prac-
titioner avoid when treating patients with emphysema?
A) Calcium channel blockers
B) Angiotensin-converting enzyme (ACE) inhibitors
C) Beta-blockers
D) Diuretics
Answer> Beta-blockers
Beta-blockers should be avoided in patients with a history of emphysema.
Studies have shown evidence of a reduction in forced expiratory volume in 1
second (FEV1), increased airway hyperresponsiveness, and inhibition of
bronchodilator response to beta agonists in patients receiving non-selective
beta- blockers and high doses of cardioselective beta-blockers.
4. A 30-year-old chef complains of pruritic hives over her chest and arms

C) Give an injection of epinephrine 1:1000 intramuscularly stat
D) Call 911
, Answer> Perform a complete and thorough history
Prior to prescribing medications, a complete and thorough history must be
per- formed to determine possible causes of hives. The patient denied
difficulty with swallowing and breathing, so there was no medical emergency
to require calling 911.
