Correct Answer: C

Rationale: The correct answer is C: Fever. Fever can indicate a serious hypersensitivity reaction to allopurinol, known as allopurinol hypersensitivity syndrome, which can be severe and even life-threatening. Nausea and drowsiness are common side effects of allopurinol but not necessarily indications to discontinue the medication. Metallic taste is not typically associated with allopurinol use. Therefore, the nurse should emphasize to the client the importance of reporting any signs of fever promptly for further evaluation and management.

Correct Answer: B

Rationale: Candidiasis is a type of superinfection that can occur when antibiotics, like tetracycline, disrupt the normal flora, allowing overgrowth of fungi. Option A, allergic response, is incorrect because candidiasis is not typically an allergic reaction. Option C, renal toxicity, and option D, hepatotoxicity, are incorrect as they refer to adverse effects on the kidneys and liver, respectively, which are not directly related to the development of candidiasis.

Correct Answer: A

Rationale: To calculate the mL needed, set up a proportion: 5 mg / 1 mL = 2.5 mg / X mL. Cross multiply to find X: 5 * X = 2.5 * 1, X = 2.5 / 5 = 0.5 mL. Therefore, the nurse should administer 0.5 mL. Choice B, 0.005 mL, is incorrect as it doesn't match the calculated result. Choice C, 0.05 mL, is incorrect as it is ten times the correct value. Choice D, 5 mL, is incorrect as it represents the total volume of the entire vial, not the amount needed for the specific dose.

Correct Answer: A

Rationale: The correct answer is A: Blood pressure. Epoetin alfa can increase blood pressure, especially in clients with chronic kidney failure. Monitoring blood pressure before administration is crucial to prevent hypertension. Reviewing temperature, blood glucose levels, or total protein levels is not directly related to the potential side effect of increased blood pressure associated with epoetin alfa.

Correct Answer: D

Rationale: Phenazopyridine can turn the urine orange, which is a normal side effect and not a cause for alarm. The client's statement about notifying the provider immediately if their urine turns orange indicates a need for further teaching because it shows a misunderstanding of the medication's side effects. Choices A, B, and C demonstrate a good understanding of the prescribed medications and their effects, indicating the client has grasped the teaching provided on those aspects.
