CFA Perioperative Assessment 2

Question 1

A patient scheduled for elective surgery has a serum creatinine of 2.4 mg/dL. What is the PRIMARY concern for the first assistant?

Accepted Answer

Impaired drug clearance and increased anesthetic sensitivity

Answer

Elevated creatinine indicates renal impairment, which delays drug clearance and increases sensitivity to anesthetics and other perioperative medications.

Question 2

During a preoperative assessment, the patient reports taking warfarin for atrial fibrillation. Which lab value is MOST critical to review before proceeding?

Accepted Answer

International normalized ratio (INR)

Answer

INR directly measures the anticoagulant effect of warfarin and is the standard test used to guide perioperative anticoagulation management.

Question 3

A patient has a BMI of 48. Which perioperative complication should the first assistant anticipate most vigilantly?

Accepted Answer

Difficult airway and respiratory compromise

Answer

Morbid obesity significantly increases the risk of difficult intubation and postoperative pulmonary complications including hypoxia and atelectasis.

Question 4

Which ASA physical status classification describes a patient with severe systemic disease that is a constant threat to life?

Accepted Answer

ASA IV

Answer

ASA IV describes a patient with a severe systemic disease that is a constant threat to life, while ASA V is a moribund patient not expected to survive without surgery.

Question 5

A patient undergoing preoperative assessment reports smoking one pack per day for 20 years. Which pulmonary function change is MOST expected?

Accepted Answer

Reduced FEV1 and air trapping

Answer

Chronic smoking causes obstructive pulmonary disease, characterized by reduced FEV1, decreased FEV1/FVC ratio, and air trapping.
