There are choices for this question namely:
<span>1 Pulse oximetry of 90%
2 Body temperature of 99° F
3 Heart rate of 40 bpm
4 Respiratory rate of 20 breaths per minute
</span>
The correct answer is "heart rate of 40 bpm". A heart rate of 40 bpm is classified as bradycardia. Bradycardia is defined as a slow heart rate below 60 bpm. A heart rate below 50 bpm is more than alarming to the health practitioner and suctioning should be stopped to give way for immediate intervention. A oxygen saturation of 90%, while below normal range of 95%-100%, is still considered safe. A body temperature of 99 degrees F and a respiratory rate of 20 breaths per minute is considered normal.
