A client has a new prescription for spironolactone. The client should be monitored for which of the following adverse effects?
- A. Hyperkalemia
- B. Hyponatremia
- C. Hypokalemia
- D. Hypercalcemia
Correct Answer: A
Rationale: Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia as an adverse effect. Hyperkalemia is characterized by elevated levels of potassium in the blood, which can be dangerous and lead to cardiac arrhythmias. Therefore, monitoring for signs and symptoms of hyperkalemia is crucial when a client is taking spironolactone.
When administering the drug lithium, what is one important side effect to watch for?
- A. Anaphylaxis
- B. Seizures
- C. Angioedema
- D. Pulmonary Edema
Correct Answer: C
Rationale: When administering lithium, it is crucial to watch for the side effect of angioedema. Angioedema is a potential adverse reaction associated with lithium therapy, characterized by rapid swelling beneath the skin, often around the eyes and lips. Monitoring for this side effect is essential to promptly address and manage any signs of angioedema that may occur during lithium treatment.
The following is most suitable for thromboembolic prophylaxis in a patient with a left ventricular aneurysm following a myocardial infarction three months ago:
- A. Intravenous heparin
- B. Subcutaneous enoxaparin
- C. Oral warfarin
- D. Oral aspirin
Correct Answer: C
Rationale: A left ventricular aneurysm post-MI risks thrombus formation due to stasis, necessitating anticoagulation. IV heparin is acute, not outpatient prophylaxis, impractical here. Subcutaneous enoxaparin prevents thromboembolism short-term (e.g., post-surgery), but its duration suits weeks, not months. Oral warfarin, a vitamin K antagonist, provides long-term anticoagulation (INR 2-3), ideal for chronic prophylaxis against mural thrombi embolizing to systemic circulation, most suitable three months post-MI. Oral aspirin (antiplatelet) or aspirin plus clopidogrel targets arterial clots, less effective for ventricular stasis-related venous thrombi. Warfarin's sustained effect reduces stroke risk, critical in this structural heart defect.
