A patient has had respiratory failure, been intubated, and is now being mechanically ventilated. While suctioning the patient, the heart rate increases from 79 to 112 beats per minute.

What would cause this increase in heart rate?

Airway obstruction
Atelectasis
Bradycardia
Hypoxemia

Explanation

Answer: D-Hypoxemia is a normal side effect of suctioning, and could cause the heart rate to increase.

Neither an airway obstruction nor atelectasis would affect the patient’s heart rate. Bradycardia is the lowering of heart rate, not increasing, so it would not be an accurate cause.
