An elderly client is diagnosed with ovarian cancer. She has surgery followed by chemotherapy with fluorouracil (Adrucil) IV. What should the nurse do if she notices crystals and cloudiness in the IV medication?

Correct Answer: A

Rationale: Crystals in the solution are not normal and should not be administered to the client. Discarding the solution and ordering a new bag is the correct action to ensure the client's safety. Warming the solution, as suggested in answer B, will not resolve the issue of crystals and cloudiness, which could potentially harm the client. Continuing the infusion, as in answer C, could pose a risk to the client due to the presence of abnormal substances. Answer D, discontinuing the medication, would typically require a doctor's order and should be done after discarding the contaminated solution.

Correct Answer: B

Rationale: The correct answer is telling the client that the medication will change the color of the urine. Rifampin can change the color of the urine and body fluid. Teaching the client about these changes is important as the client might think this is a complication. Answer A is incorrect because there is no specific requirement to take rifampin with juice. Answer C is incorrect because rifampin should be taken at consistent times, not necessarily before going to bed. Answer D is incorrect as rifampin should be taken regularly as prescribed, not based on symptoms like night sweats.

Correct Answer: D

Rationale: Taking corticosteroids in the morning mimics the body's natural release of cortisol, which follows a diurnal pattern with higher levels in the morning. This timing helps regulate the body's inflammatory response and minimizes potential side effects. Answer A is not the primary reason for morning dosing, as adherence concerns can be addressed through other means. Answer B is incorrect since fluid retention is not influenced by the timing of prednisone administration. Answer C is also incorrect as prednisone absorption is not significantly affected by whether it is taken with breakfast or not.

Correct Answer: D

Rationale: When antibiotics and oral contraceptives are taken together, the effectiveness of the oral contraceptives can be reduced, increasing the risk of pregnancy. Therefore, it is important to advise the client to use an alternate method of birth control to prevent unintended pregnancy. Choices A, B, and C are incorrect because there is no evidence to suggest that oral contraceptives decrease the effectiveness of tetracycline, cause nausea, or result in toxicity when taken with antibiotics.
