A patient taking spironolactone has a follow-up appointment. Which of the following laboratory values would be most important to monitor?

Serum calcium levels

White blood cell count

Thyroid hormone levels

Serum potassium levels

Answer and Explanation

The Correct Answer is D

Rationale:

A. Spironolactone is a potassium-sparing diuretic and does not typically affect calcium levels. Monitoring calcium is not a priority unless the client has another condition affecting calcium metabolism.

B. Spironolactone does not directly affect WBC counts. Monitoring WBCs is unrelated to this medication unless the client is taking additional drugs that impact bone marrow or immune function.

C. Spironolactone does not influence thyroid function, so assessing TSH or thyroid hormone levels is not necessary for routine follow-up.

D. Spironolactone is a potassium-sparing diuretic, which can increase serum potassium, potentially leading to hyperkalemia, a life-threatening condition. Monitoring potassium levels is essential to ensure safe use, particularly in clients with kidney impairment or those taking other potassium-increasing medications.

Correct Answer is C

Explanation

Rationale:
A. This patient shows signs of mild pulmonary congestion, but oxygen saturation is within an acceptable range and the patient is currently stable.

B. While this patient is on a vasodilator and has borderline low blood pressure, they are hemodynamically stable at this moment and not showing signs of acute deterioration.

C. This patient exhibits signs of poor perfusion and possible cardiogenic shock, which is life-threatening. These symptoms indicate an urgent priority for assessment and intervention.

D. This is a common side effect of ACE inhibitors and is non-emergent; the patient is stable and does not require immediate assessment

A. Radiofrequency catheter ablation B. CPR C. Elective cardioversion D. Defibrillation

Correct Answer is D

Explanation

Rationale:
A. This is a long-term treatment for recurrent VT or other arrhythmias. It is not an immediate intervention for acute, unstable VT.

B. Cardiopulmonary resuscitation is performed only if the client is pulseless and unresponsive. While CPR may be necessary in cardiac arrest, it is not the first-line intervention for VT with a pulse.

C. Synchronized cardioversion is used for hemodynamically stable VT with a pulse, but the term “elective” implies a planned procedure, not emergency management.

D. For pulseless VT or VT causing severe instability (e.g., hypotension, altered mental status), defibrillation is the immediate lifesaving intervention. It delivers an unsynchronized shock to restore normal cardiac rhythm.
