Correct Answer is C

Explanation

A. Taking ginkgo biloba increases phenytoin levels: Ginkgo biloba can actually decrease the effectiveness of phenytoin, not increase it.
B. Taking phenytoin diminishes potassium levels: Phenytoin does not significantly affect potassium levels.
C. Monitor for gingival hyperplasia: Gingival hyperplasia is a common side effect of phenytoin.
D. Minimize exposure to sunlight: While this is a good practice, it is not as significant as monitoring for gingival hyperplasia with phenytoin use.

A. Administer the insulin using a tuberculin syringe at a 15° angle. B. Rapidly inject the insulin using a 20-gauge 1-inch needle. C. Insert the needle into the right thigh at a 90° angle. D. Slowly inject the insulin using the Z-track method.

Correct Answer is C

Explanation

A. Administer the insulin using a tuberculin syringe at a 15° angle: Tuberculin syringes are used for intradermal injections, not subcutaneous injections, and insulin is typically administered at a 90° angle.
B. Rapidly inject the insulin using a 20-gauge 1-inch needle: A 20-gauge needle is too large for insulin injections, which typically use smaller needles (e.g., 25- to 30-gauge).
C. Insert the needle into the right thigh at a 90° angle: Insulin injections are typically administered subcutaneously at a 90° angle, and the thigh is a common injection site.
D. Slowly inject the insulin using the Z-track method: The Z-track method is not used for insulin injections, which are administered subcutaneously, not intramuscularly.
