A nurse is caring for a client who has developed bradycardia. Which prescription should the nurse question?
- A. Propranolol
- B. Furosemide
- C. Spironolactone
- D. Valsartan
Correct Answer: A
Rationale: Propranolol, a beta-blocker, can worsen bradycardia and should be questioned. Furosemide, spironolactone, and valsartan are less likely to affect heart rate.

This nurse is caring for a client who is receiving prescribed hydralazine. Which of the following findings would indicate a therapeutic response?
- A. Blood pressure 120/70 mm Hg
- B. Pulse (P) 67/minute
- C. Total cholesterol 185 mg/dL [200 mg/dL]
- D. aPTT 45 seconds [30-40 seconds]
Correct Answer: A
Rationale: Hydralazine, a vasodilator, lowers blood pressure, so 120/70 mm Hg indicates a therapeutic response. Pulse, cholesterol, and aPTT are not directly affected.
The nurse has received a prescription for rivaroxaban. The nurse understands that this medication is prescribed to treat which condition?
- A. Pulmonary Hypertension
- B. Venous Thromboembolism (VTE)
- C. Congestive Heart Failure
- D. Hyperlipidemia
Correct Answer: B
Rationale: Rivaroxaban, a direct oral anticoagulant, is used to treat venous thromboembolism (VTE). It is not indicated for pulmonary hypertension, CHF, or hyperlipidemia.
The nurse has provided teaching to a client regarding metoprolol. Which of the following statements by the client would indicate a correct understanding of the teaching?
- A. I should stop taking metoprolol immediately if I experience any dizziness or lightheadedness.
- B. Metoprolol works by increasing the production of angiotensin II to lower blood pressure.
- C. I should monitor my heart rate regularly as metoprolol can cause bradycardia.
- D. It's essential to take metoprolol with a high-fat meal to enhance its absorption.
Correct Answer: C
Rationale: Metoprolol, a beta-blocker, can cause bradycardia, so monitoring heart rate is correct. Stopping abruptly, increasing angiotensin II, or requiring high-fat meals are incorrect.
The nurse is preparing to administer prescribed bumetanide to a client. Which clinical finding would indicate a therapeutic outcome?
- A. Increase in central venous pressure (CVP)
- B. Reduced cardiac preload and wall tension
- C. Decreased glomerular filtration rate (GFR)
- D. Increase in systemic vascular resistance (SVR)
Correct Answer: B
Rationale: Bumetanide, a loop diuretic, reduces fluid volume, leading to decreased cardiac preload and wall tension, indicating a therapeutic outcome in conditions like heart failure. Increased CVP, decreased GFR, or increased SVR are not desired effects.
The nurse is caring for a client experiencing polyarthritis associated with rheumatic fever. The nurse anticipates a prescription for which medication?
- A. Prazosin
- B. Naproxen
- C. Verapamil
- D. Furosemide
Correct Answer: B
Rationale: Naproxen, an NSAID, is used to reduce inflammation and pain in polyarthritis associated with rheumatic fever. Prazosin, verapamil, and furosemide are not indicated for this condition.
