Pharmacological and Parenteral Therapies QID 1024

Which of the following medications requires the nurse to monitor the patient's International Normalized Ratio (INR) regularly?

A:
Atorvastatin
B:
Lisinopril
C:
Metoprolol
D:
Warfarin

Explanation

Warfarin is an anticoagulant that requires regular monitoring of the INR to ensure therapeutic levels are maintained and to prevent the risks of bleeding or thrombosis. Metoprolol, Lisinopril, and Atorvastatin do not require INR monitoring as they do not have anticoagulant effects.
