NURS 104 PHARM AND MCN BEST QUIZES WITH VERIFIED ANSWERS 
Session 17
1. The three primary elements that determine the pressure in the cardiovascular system
are heart rate, stroke volume, and:
A. Baroreceptors
B. Peripheral resistance
C. Renin-Angiotensin-Aldosterone System (RAAS)
D. All of the above
ANSWER B.
Peripheral resistance.Small arterioles help regulate blood pressure in a constant basis and
are the most important factor affecting peripheral resistance. When small arterioles
constrict, they are almost able to stop the flow of the blood. Their high responsiveness to
sympathetic nervous stimulation cause them to constrict and increase blood pressure.
Baroreceptors are pressure receptors located in the arch of the aorta and carotid arteries
that send information to the brain when pressure increases. RAAS is a compensatory
mechanism activated in the kidney when blood pressure falls.
2. Untreated hypertension can result to which of the following:
A. Stroke
B. Renal failure
C. Loss of vision
D. All of the above
ANSWER D.
All of the above.
The force of the blood propelled against blood vessels can damage their linings, making
them susceptible to atherosclerosis and narrowing. When these happen, tiny vessels in the
retina, kidneys, and brain can be destroyed leading to unresponsiveness of the system
3. A student nurse was asked to take the blood pressure of a patient in the emergency
room. The BP reads 140/90 mmHg. She would be correct to say that this BP belongs to
classification.
A. Normal
B. Elevated
C. Stage 1 Hypertension
D. Stage 2 Hypertension
ANSWER D.
Stage 2 Hypertension. A category rating the severity of hypertension has been devised and
the classifications of blood pressure are as follows: Normal – systolic: <120 mmHg;
diastolic:
<80 mmHg; Elevated – systolic: 120-129 mmHg; diastolic: <80 mmHg; Stage 1
Hypertension – systolic: 130-139 mmHg; diastolic: 80-89 mmHg; Stage 2 Hypertension –
systolic: less than or equal to 140 mmHg; diastolic: less than or equal to 90 mmHg.
4. Which of the following medications will decrease the therapeutic effects of quinapril
(Accupril)?
A. NSAIDs
B. Allopurinol
C. Antacids
D. All of the above
ANSWER A.
NSAIDs. Quinapril belongs to the class ACE inhibitors. NSAIDs are linked to decreased
antihypertensive effects of ACE inhibitors. Allopurinol increases risk of hypersensitivity when
combined with ACE inhibitors.
5. A patient receiving nitroprusside begun manifesting headache, distant heart sounds,
imperceptible pulses, and shallow breathing. The nurse knows that these are signs of?
B. Hypothyroidism
C. Cyanide toxicity
D. Severe alteration of blood pressure
ANSWER C.
Cyanide toxicity. Nitroprusside is metabolized into cyanide. Other manifestations of cyanide
toxicity include pink color, loss of consciousness, and absence of reflexes.
6. the nurse is administering antihypertensive drugs to older adults patients. the nurse
knows that which adverse effect is of most concern for these patients?
A. dry mouth
B. hypotension
C. restlessness
D. constipation
ANSWER B Hypotension. A client receiving furosemide (Lasix) as an adjunct to treatment of
hypertension returns for follow-up.
7. Which of the following objective data should the nurse consider when determining the
effectiveness of the drug therapy?
A. Blood pressure log notes blood pressure 120/70-134/88 since discharge.
B. Weight loss of six pounds in the past month
C. Frequency of voiding of at least six times per day
D. Absence of edema in lower extremities
ANSWER A.
Maintenance of blood pressure within normal limits indicates that treatment goals are
achieved. Absence of edema, weight loss, and urinating all indicate that the diuretic has
promoted fluid loss, but are not the best measure of the drug's effectiveness for
hypertension.
