NBSTSA Surgical Pharmacology & Anesthesia 5

Question 1

During a procedure, the anesthesia provider administers neostigmine. Which drug must be co-administered to prevent bradycardia?

Accepted Answer

Atropine or glycopyrrolate

Answer

Neostigmine inhibits acetylcholinesterase and can cause bradycardia via muscarinic effects; anticholinergics like atropine or glycopyrrolate are given concurrently to counteract this.

Question 2

Which controlled substance schedule applies to fentanyl under the DEA classification?

Accepted Answer

Schedule II

Answer

Fentanyl is a Schedule II controlled substance, indicating high abuse potential with accepted medical use but severe potential for dependence.

Question 3

A patient receives ketamine for dissociative anesthesia. What is a unique hemodynamic effect of this agent compared to most other anesthetics?

Accepted Answer

It stimulates the sympathetic nervous system, increasing heart rate and blood pressure

Answer

Ketamine is unique among anesthetics in that it stimulates the sympathetic nervous system, typically increasing heart rate, blood pressure, and cardiac output.

Question 4

Which antibiotic class is most commonly used for surgical site infection prophylaxis and is typically given within 60 minutes prior to incision?

Accepted Answer

First-generation cephalosporins

Answer

First-generation cephalosporins such as cefazolin are the standard for surgical prophylaxis due to their broad-spectrum coverage against common skin organisms and favorable safety profile.

Question 5

Which topical hemostatic agent is derived from bovine collagen and works by activating the coagulation cascade at the wound site?

Accepted Answer

Microfibrillar collagen (Avitene)

Answer

Microfibrillar collagen (Avitene) activates platelet aggregation and the intrinsic coagulation pathway by direct contact with blood, providing mechanical and biochemical hemostasis.
