finding should prompt the nurse to hold the medication?
A. Respiratory rate of 18/min
B. Blood pressure of 140/86 mmHg
C. Apical pulse of 50 bpm
D. Potassium level of 4.0 mEq/L
Holding digoxin is indicated if the apical pulse is below 60 bpm due to
increased risk of toxicity.
2. A patient taking warfarin asks about dietary restrictions. Which food should
the nurse instruct the patient to limit?
A. Bananas
B. Chicken
C. Spinach
D. Apples
Spinach is high in vitamin K, which can antagonize warfarin’s
anticoagulant effect.

4. Which instruction should the nurse give a patient prescribed tetracycline?
A. Take with milk

Tetracyclines cause photosensitivity, increasing the risk of sunburn.
5. A patient with asthma is prescribed albuterol. The nurse knows this
medication works by:
A. Decreasing inflammation
B. Increasing mucus production
C. Relaxing bronchial smooth muscle
D. Blocking histamine release
Albuterol is a beta-2 agonist that causes bronchodilation.
6. A nurse is administering furosemide. Which laboratory value is most
important to monitor?
A. Calcium
B. Glucose
C. Magnesium
D. Potassium
Furosemide is a loop diuretic that causes potassium loss, risking
hypokalemia.
, 7. Which medication is contraindicated in pregnancy due to risk of fetal harm?
A. Amoxicillin
B. Isotretinoin
C. Acetaminophen
D. Penicillin
Isotretinoin is highly teratogenic and contraindicated during pregnancy.
8. A patient is taking levothyroxine. Which indicates a therapeutic response?
A. Decreased urine output
B. Increased energy levels
C. Weight gain
D. Bradycardia
Levothyroxine treats hypothyroidism; increased energy suggests improved
thyroid function.
9. Which medication is used as an antidote for opioid overdose?
A. Protamine sulfate
B. Flumazenil
C. Vitamin K
D. Naloxone
Naloxone is an opioid antagonist that reverses opioid effects.
10.A nurse is teaching a patient about nitroglycerin. Which statement indicates
correct understanding?
A. “I should swallow the tablet whole.”
