A 74-year-old client with a history of heart failure is admitted to the coronary care unit with acute pulmonary edema. They are intubated and placed on a ventilator. Which of the following parameters should the nurse closely monitor in assessing the client's response to a bolus dose of IV furosemide (Lasix)?
Serum sodium levels
Daily weight
Hourly urine output
24-hour intake and output
The Correct Answer is C
A. Serum sodium levels are important to monitor over time with diuretic therapy but do not provide immediate feedback on the effect of a bolus dose of furosemide.
B. Daily weight helps assess long-term fluid status but is not helpful for evaluating an acute response.
C. Hourly urine output is the most appropriate and immediate measure to assess the effectiveness of a bolus dose of IV furosemide, especially in a critically ill client with acute pulmonary edema.
D. 24-hour intake and output provides a broader picture but does not offer real-time assessment like hourly output does.

Correct Answer is A
Explanation
A. High-quality CPR with minimal interruptions is the cornerstone of asystole management. Asystole is a non-shockable rhythm, so maintaining perfusion through effective chest compressions and administering appropriate medications (like epinephrine) is essential.
B. Cessation of resuscitation efforts after only 2 minutes is inappropriate; the decision to stop should be based on the clinical scenario and response to interventions over time.
C. Narcan (naloxone) is used for opioid overdose, not for treating asystole unless there is a suspected opioid-related cause—and it does not directly restore electrical cardiac rhythm.
D. Defibrillation is not indicated in asystole, as it is a non-shockable rhythm. Continuous defibrillation is ineffective and inappropriate.
Correct Answer is D
Explanation
A. Mitral valve prolapse often requires no treatment or is managed with medications; balloon valvuloplasty is not typically used.
B. Aortic regurgitation usually requires surgical valve replacement rather than valvuloplasty.
C. Mitral regurgitation involves backward blood flow and is generally treated with valve repair or replacement, not balloon valvuloplasty.
D. Mitral stenosis is most commonly treated with balloon valvuloplasty, especially in clients with rheumatic heart disease. This procedure helps open a narrowed mitral valve by inflating a balloon within the valve to improve blood flow.
