The operating room nurse assisting with the surgical removal of an adrenal tumor is aware that the patient's vital signs may change upon manipulation of the tumor. The vital sign changes that the nurse may expect to see include:
A) Hyperthermia and tachypnea
B) Hypertension and heart rate changes
C) Hypotension and hypothermia
D) Hyperthermia and bradycardia
Ans: B
Feedback: Manipulation of the tumor during surgical excision may cause release of stored epinephrine and norepinephrine, with marked increases in blood pressure and changes in heart rate. Sodium nitroprusside and alpha-adrenergic blocking agents may be required during and after surgery. While other vital sign changes may occur related to surgical complications, the most common changes related to hypertension are changes in the heart rate.
