Question 1

A patient receiving spinal anesthesia develops sudden hypotension. What is the most likely cause?

Accepted Answer

Sympathetic blockade causing vasodilation

Answer

Spinal anesthesia blocks sympathetic nerves, causing vasodilation and a drop in blood pressure, the most common complication of neuraxial anesthesia.

Question 2

Which action is most important when transferring a patient from the OR table to the PACU stretcher?

Accepted Answer

Ensure adequate personnel and protect the patient's airway during transfer

Answer

Safe patient transfer requires sufficient personnel to prevent falls and injury, and the airway must be protected throughout the move from OR to PACU.

Question 3

Which preoperative patient teaching point is most important for a patient undergoing general anesthesia?

Accepted Answer

NPO (nothing by mouth) requirements and why they are necessary

Answer

NPO status is critical to prevent aspiration of gastric contents during anesthesia induction, which can cause aspiration pneumonia or death.

Question 4

The perioperative nurse notes the patient's preoperative consent form is not signed before the patient receives preoperative sedation. What should the nurse do?

Accepted Answer

Notify the surgeon and hold preoperative medications until consent is obtained

Answer

Informed consent must be obtained while the patient is alert and competent; sedation impairs decision-making capacity, so medication must be withheld until consent is signed.

Question 5

Which intervention is most effective for preventing deep vein thrombosis (DVT) in the perioperative patient?

Accepted Answer

Applying sequential compression devices (SCDs) before and during surgery

Answer

Sequential compression devices improve venous return and reduce stasis, making them a primary mechanical intervention for DVT prevention in surgical patients.
