Surgical Pharmacology & Anesthesia Flashcards

The scrub technologist is responsible for which action when contrast media is placed on the sterile field for a fluoroscopic procedure?

Answer: Drawing up the contrast in a sterile syringe and labeling it

The scrub technologist draws contrast into a labeled sterile syringe for the surgeon's use; labeling is mandatory immediately upon transfer to the sterile field.

Which antibiotic is most commonly administered as prophylaxis within 60 minutes before surgical incision?

Answer: Cefazolin (Ancef)

Bone wax is used intraoperatively to control bleeding from:

Answer: Bone surfaces (medullary cavity)

Bone wax is a sterile mixture of beeswax and softening agents applied by physical pressure to control bleeding from the cut surfaces of bone.

Oxidized regenerated cellulose (Surgicel) achieves hemostasis through which mechanism?

Answer: Lowering local pH and activating the coagulation cascade

Surgicel (oxidized cellulose) lowers the local pH when moistened with blood, denaturing proteins and facilitating hemostasis through a physical and chemical mechanism.

Which anesthetic technique provides excellent postoperative analgesia while allowing the patient to remain awake during surgery?

Answer: Regional nerve block

Regional nerve blocks provide targeted anesthesia to a specific body region while the patient remains awake and also provide extended postoperative pain control.

The drug category that includes midazolam (Versed) and is commonly used for preoperative anxiolysis and amnesia is:

Answer: Benzodiazepines

Midazolam is a benzodiazepine that provides preoperative anxiolysis, sedation, and anterograde amnesia by enhancing GABA-mediated CNS inhibition.
