Question 1

A patient on warfarin has an INR of 4.8 with no signs of bleeding. What is the most appropriate clinical action?

Accepted Answer

Hold 1-2 doses and recheck INR in 1-2 days

Answer

For supratherapeutic INR (4.5-10) without bleeding, holding 1-2 doses and rechecking INR in 24-48 hours is the standard approach.

Question 2

Which serum creatinine-based equation is preferred for adjusting medication doses in patients with chronic kidney disease?

Accepted Answer

CKD-EPI creatinine equation

Answer

The CKD-EPI creatinine equation provides the most accurate GFR estimate for CKD staging and is preferred by major nephrology guidelines.

Question 3

A patient with type 2 diabetes has an A1C of 9.2% on metformin monotherapy. Which add-on agent provides the greatest A1C reduction while minimizing hypoglycemia risk?

Accepted Answer

Semaglutide

Answer

GLP-1 receptor agonists like semaglutide provide 1.5-2% A1C reduction with low hypoglycemia risk and additional cardiovascular benefits.

Question 4

Which laboratory finding most urgently warrants discontinuation of an ACE inhibitor?

Accepted Answer

Serum potassium of 6.5 mEq/L with ECG changes

Answer

Severe hyperkalemia (≥6.0 mEq/L) with ECG changes represents a life-threatening emergency requiring immediate ACE inhibitor discontinuation.

Question 5

When monitoring a patient on amiodarone long-term, which organ system requires the MOST frequent surveillance due to potentially irreversible toxicity?

Accepted Answer

Thyroid (TFTs every 6 months)

Answer

Amiodarone contains 37% iodine by weight and causes thyroid dysfunction in up to 14% of patients, requiring TFT monitoring every 6 months.
