A nurse is preparing to administer a medication to a client for the first time and needs to know about potential food and medication interactions. Which of the following actions should the nurse take?

Check the client’s medical record for medication and food interactions.

Consult a drug reference guide for possible interactions.

Ask another nurse if they are aware of potential interactions.

Have the client take the medication on an empty stomach to avoid interactions.

Answer and Explanation

The Correct Answer is B

A. Check the client’s medical record for medication and food interactions is important, but it may not provide comprehensive information about all potential interactions.
B. Consult a drug reference guide for possible interactions is the best action. Drug reference guides provide detailed and up-to-date information about potential food and medication interactions, ensuring safe administration.
C. Ask another nurse if they are aware of potential interactions can be helpful, but it should not be the primary source of information. It is better to rely on authoritative drug reference guides.
D. Have the client take the medication on an empty stomach to avoid interactions is not always appropriate. Some medications need to be taken with food to enhance absorption or reduce gastrointestinal side effects.

Correct Answer is B

Explanation

A. PTT (partial thromboplastin time) is used to monitor heparin therapy, not warfarin. It measures the intrinsic pathway of coagulation.
B. PT (prothrombin time) is the correct test to review before administering warfarin. PT measures the extrinsic pathway of coagulation and is used to calculate the INR (International Normalized Ratio), which helps monitor and adjust warfarin dosage to ensure therapeutic levels and prevent complications.
C. Total iron-binding capacity is a measure of iron status and is not relevant to warfarin therapy.
D. WBC (white blood cell count) is important for assessing infection or immune status but is not directly related to monitoring warfarin therapy.

A. “You should take this medication once each day at bedtime.” B. “You can continue to wear soft contact lenses while taking this medication.” C. “This medication will not interfere with the effectiveness of oral contraceptives.” D. “Your urine will turn orange while you are taking this medication.”

Correct Answer is D

Explanation

A. “You should take this medication once each day at bedtime.” This statement is incorrect because rifampin is typically taken on an empty stomach, either 1 hour before or 2 hours after a meal, to ensure optimal absorption. Taking it at bedtime is not a standard recommendation.
B. “You can continue to wear soft contact lenses while taking this medication.” This statement is incorrect because rifampin can cause discoloration of bodily fluids, including tears, which can stain soft contact lenses. Patients are usually advised to avoid wearing soft contact lenses during treatment.
C. “This medication will not interfere with the effectiveness of oral contraceptives.” This statement is incorrect because rifampin is known to reduce the effectiveness of oral contraceptives. Patients should be advised to use an alternative or additional form of contraception while taking rifampin.
D. “Your urine will turn orange while you are taking this medication.” This statement is correct. Rifampin commonly causes a harmless discoloration of urine, sweat, saliva, and tears to an orange or reddish color. Patients should be informed about this side effect to avoid unnecessary concern.
