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
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.
