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 B
Explanation
A. An atrial rhythm regular and ventricular rhythm irregular would suggest an arrhythmia such as atrial fibrillation or flutter with variable conduction—not sinus tachycardia.
B. In sinus tachycardia, the rhythm is regular, the P:QRS ratio is 1:1, meaning each P wave is followed by a QRS complex, and the origin is from the sinus node.
C. A 2:1 P:QRS ratio is characteristic of certain types of heart block or atrial flutter—not sinus tachycardia.
D. Irregular ventricular and atrial rhythms are seen in atrial fibrillation or other irregular arrhythmias, not sinus tachycardia.
Correct Answer is B
Explanation
A. Airway: Ensure the airway is open.
B. Breathing: Provide rescue breaths if the person is not breathing.
C. Circulation: Begin chest compressions to maintain blood flow.
D. Defibrillation: Use an automated external defibrillator (AED) as soon as it's available, especially in cases of shockable rhythms like ventricular fibrillation.
