, Question 1
A patient with a history of heart failure is prescribed furosemide 40 mg IV
push. Which assessment finding should the nurse report immediately before
administering the dose?
A. Serum potassium 3.1 mEq/L
B. Blood pressure 118/72 mm Hg
C. Urine output 50 mL/hr
D. Serum sodium 138 mEq/L
Correct Answer: A - Serum potassium 3.1 mEq/L
RATIONALE
Furosemide is a loop diuretic that causes potassium loss; a serum
potassium of 3.1 mEq/L is below normal (3.5-5.0) and increases risk
for digoxin toxicity and dysrhythmias. The other values are within
normal limits and do not require immediate reporting.
Question 2
A provider orders levothyroxine 0.125 mg PO daily for a patient with
hypothyroidism. The pharmacy supplies levothyroxine 50 mcg tablets. How
many tablets should the nurse administer per dose?
A. 1.5 tablets
B. 2.5 tablets
C. 2 tablets
D. 3 tablets
Correct Answer: B - 2.5 tablets
RATIONALE
Convert 0.125 mg to mcg: 0.125 mg × 1000 = 125 mcg. Then divide
by 50 mcg per tablet: 125 ÷ 50 = 2.5 tablets. Therefore, the nurse
should administer 2.5 tablets.

, Question 3
Which statement by a patient newly prescribed warfarin indicates a need for
further teaching?
A. I will use an electric razor to shave.
B. I will increase my intake of leafy green vegetables.
C. I will report any unusual bruising or bleeding.
D. I will keep my INR checked regularly.
Correct Answer: B - I will increase my intake of leafy green
vegetables.
RATIONALE
Warfarin's anticoagulant effect is antagonized by vitamin K, which is
abundant in leafy green vegetables. Increasing intake can reduce the
drug's effectiveness and destabilize the INR. The other statements
reflect correct safety measures.
Question 4
A nurse is reviewing a prescription for a patient with renal impairment:
'gentamicin 5 mg/kg IV every 24 hours.' Which action should the nurse take
first?
A. Administer the dose as prescribed.
B. Hold the dose and contact the prescriber.
C. Administer the dose and monitor peak levels.
D. Reduce the dose by half and administer.
Correct Answer: B - Hold the dose and contact the prescriber.
RATIONALE
Gentamicin is nephrotoxic and requires dose adjustment in renal
impairment. The nurse should hold the dose and clarify the
prescription with the prescriber, as the current order may not account
for reduced clearance. Administering as prescribed could cause
toxicity.

, Question 5
A patient receiving morphine via PCA pump has a respiratory rate of 8/min
and is difficult to arouse. Which medication should the nurse prepare to
administer?
A. Naloxone
B. Flumazenil
C. Atropine
D. Protamine sulfate
Correct Answer: A - Naloxone
RATIONALE
Naloxone is an opioid antagonist used to reverse opioid-induced
respiratory depression. Flumazenil reverses benzodiazepines, atropine
treats bradycardia, and protamine sulfate reverses heparin.
Question 6
Which instruction should the nurse include when teaching a patient about
sublingual nitroglycerin for angina?
A. Swallow the tablet with water for faster absorption.
B. Take one tablet every 5 minutes up to 3 doses; if pain persists, call
911.
C. Take the medication only when pain is severe.
D. Store the tablets in a clear plastic container.
Correct Answer: B - Take one tablet every 5 minutes up to 3
doses; if pain persists, call 911.
RATIONALE
Sublingual nitroglycerin should be taken at the onset of angina, one
tablet every 5 minutes for up to 3 doses. If pain persists after 3 doses,
the patient should seek emergency care. Swallowing the tablet,
waiting for severe pain, or storing in clear containers are incorrect.
