1. A nurse is administering digoxin. Which finding requires
immediate intervention?
A. Heart rate 58 bpm
B. Blood pressure 120/80 mmHg
C. Respiratory rate 16/min
D. Potassium level 4.0 mEq/L
Answer: A
Rationale: Digoxin toxicity risk increases with heart rate <60 bpm
in adults. Hold the medication and notify the provider. Normal
potassium is 3.5-5.0, but low potassium increases toxicity risk.
2. A patient on warfarin has an INR of 4.5. What action should
the nurse take?
A. Administer vitamin K as ordered
B. Give the next warfarin dose
,C. Increase the warfarin dose
D. Recheck INR in 1 week
Answer: A
Rationale: Therapeutic INR for most conditions is 2-3. INR 4.5
indicates high bleeding risk. Vitamin K reverses warfarin effect.
Hold warfarin and notify provider.
3. A client is prescribed enoxaparin (Lovenox). Which
statement indicates understanding?
A. "I will take this pill with food."
B. "I will inject it into my muscle."
C. "I will inject it into my abdomen."
D. "I will check my PT/INR regularly."
Answer: C
Rationale: Enoxaparin is a low-molecular-weight heparin given
subcutaneously in the abdomen. It does not require INR
monitoring (unlike warfarin). Do not give IM.
4. A nurse provides education on albuterol. Which is a
common side effect?
A. Bradycardia
B. Hypoglycemia
,C. Tachycardia
D. Drowsiness
Answer: C
Rationale: Albuterol is a beta-2 agonist that can cause beta-1
effects (tachycardia, palpitations). Other side effects include
tremor and nervousness.
5. A client takes lithium for bipolar disorder. Which lab value
should the nurse monitor closely?
A. Sodium
B. Calcium
C. Lithium level
D. Hemoglobin
Answer: C
Rationale: Lithium has a narrow therapeutic index (0.6-1.2
mEq/L). Toxicity can occur with dehydration, low sodium, or renal
impairment. Monitor lithium levels and kidney function.
6. A patient is prescribed metformin. Which instruction is
most important?
A. Take with a high-fat meal
B. Expect weight gain
, C. Report muscle pain or weakness
D. Monitor for hyperglycemia
Answer: C
Rationale: Metformin can cause lactic acidosis (rare but serious).
Symptoms include muscle pain, weakness, trouble breathing,
dizziness. Take with meals to reduce GI upset.
7. A nurse administers furosemide (Lasix). Which finding
indicates a therapeutic effect?
A. Blood pressure 180/100 mmHg
B. Crackles in lung bases
C. Urine output 200 mL in 2 hours
D. Weight gain of 2 kg in 24 hours
Answer: C
Rationale: Furosemide is a loop diuretic used for edema and
hypertension. Therapeutic effect is increased urine output,
reduced edema, lower BP. Crackles and weight gain indicate fluid
overload.
8. A client is prescribed amoxicillin. Which adverse effect
requires immediate reporting?
A. Diarrhea
B. Nausea
