Correct Answer is C

Explanation

warfarin inhibits vitamin K epoxide reductase interfering with the synthesis of vitamin K dependent clotting factors (II, VII, IX, and X). This prolongs the prothrombin time, expressed in the form of INR international normalized ratio. Monitoring of INR helps to ensure that the prescribed dosages are within the therapeutic levels without increasing the risk of bleeding. The target INR range is between 2.5 and 3.5.
A. Used to monitor heparin therapy

B, D- not used for monitoring

A. Monitor for increased muscle spasms. B. Discontinue medication if nausea occurs. C. Avoid driving until effects are known. D. Expect urine to turn orange.

Correct Answer is C

Explanation

Cyclobenzaprine is a muscle relaxant used to relieve muscle spasms in various musculoskeletal conditions. One of the common side effects of cyclobenzaprine is drowsiness and impaired cognitive function, which can affect the ability to operate machinery or drive safely.
A. Cyclobenzaprine is used to reduce muscle spasms, so monitoring for increased muscle spasms would not be appropriate.
B. Nausea can be a common side effect of cyclobenzaprine, but it does not typically require discontinuation of the medication unless it is severe or persistent and causing significant distress.
D. Cyclobenzaprine does not typically cause urine discoloration, so expecting urine to turn orange is not relevant to the medication.
