A patient's heart rate increased from 94 to 164 beats/min. What will the nurse expect as a result?

Decrease in hemoglobin level

Increase in diastolic filling time

Increase in stroke volume

Decrease in cardiac output

Answer and Explanation

The Correct Answer is D

A. An increase in heart rate does not directly affect hemoglobin levels; this option is incorrect.
B. A higher heart rate decreases diastolic filling time, as there is less time for the heart to fill between beats, which can lead to reduced stroke volume.
C. An increased heart rate does not inherently increase stroke volume; in fact, at very high rates, stroke volume can decrease due to reduced filling time.
D. The significant increase in heart rate to 164 beats/min can lead to decreased cardiac output due to compromised diastolic filling and reduced stroke volume.

Correct Answer is A

Explanation

B. While neurological assessment is important in various conditions, it is secondary to assessing cardiac status in hyperkalemia.
C. Gastrointestinal symptoms can occur with hyperkalemia, but they do not pose an immediate life-threatening risk like cardiac issues do.
D. Respiratory assessment is essential in many contexts, but the immediate threat of hyperkalemia lies in its impact on heart function, making cardiac assessment the most critical.
