Q1. The nurse is preparing to administer the first dose of
hydrochlorothiazide 50 mg to a patient who has a blood
pressure of 160/95 mmHg. The nurse notes that the
patient had a urine output of 200 mL in the past 12
hours. The nurse will perform which action?
A) Administer the medication as ordered
B) Encourage the patient to drink more fluids
C) Hold the medication and request an order for serum
BUN and creatinine
D) Request an order for serum electrolytes and
administer the medication
Correct Answer: C) Hold the medication and request an
order for serum BUN and creatinine
Rationale: Urine output of 200 mL in 12 hours is low (<30
mL/hr). Hydrochlorothiazide is a thiazide diuretic that
requires adequate renal function to be effective . The
,nurse should hold the medication and request renal
function tests (BUN, creatinine) to assess kidney function
before administration.
Q2. A male client is prescribed prazosin for hypertension.
He asks the nurse how the medication works. What is the
nurse's best response?
A) "It increases the supply of oxygen to your heart."
B) "It works by making your blood vessels dilate."
C) "It works by inhibiting the movement of calcium across
the membrane."
D) "It promotes the excretion of sodium and water."
Correct Answer: B) "It works by making your blood
vessels dilate."
Rationale: Prazosin is an alpha-1 blocker that causes
vasodilation by blocking alpha-1 receptors on blood
vessels . This leads to decreased peripheral resistance
and lowered blood pressure. Prazosin is also used for
benign prostatic hyperplasia (BPH).
, Q3. A client, hospitalized with heart failure, is receiving
digoxin and furosemide intravenously and now has
continuous ringing in the ears. What is the appropriate
action for the nurse to take at this time?
A) Notify the provider and request a digoxin level to
check for toxicity
B) Note the observation in the medical record and plan to
reassess in 2 hours
C) Ask the client about taking aspirin in addition to other
medications
D) Withhold the furosemide and notify the health care
provider
Correct Answer: D) Withhold the furosemide and notify
the health care provider
Rationale: Continuous ringing in the ears (tinnitus) is a
sign of ototoxicity caused by furosemide, especially with
rapid IV administration . The furosemide should be
withheld, and the provider notified. Digoxin toxicity
typically causes visual changes (yellow-green halos), not
tinnitus.
