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.

Correct Answer: C

Rationale: The correct answer is C: Muscle weakness. Chlorothiazide, a thiazide diuretic, can lead to hypokalemia, which can cause muscle weakness. Thrombophlebitis (choice A) is not typically associated with chlorothiazide use. Hyperactive reflexes (choice B) and hypoglycemia (choice D) are also not commonly linked to this medication. Therefore, monitoring for muscle weakness is crucial when a client is prescribed chlorothiazide.

Correct Answer: A

Rationale: To calculate the dosage per dose, first, convert the toddler's weight from pounds to kilograms: 22 lb / 2.2 = 10 kg. Then, multiply the weight by the dosage: 4 mg 10 kg = 40 mg/day. Since this total daily dose is divided into 2 equal doses, the nurse should administer 20 mg per dose. Therefore, the correct answer is 20 mg. Choice B (15 mg) is incorrect because it does not account for the correct weight conversion and dosage calculation. Choice C (10 mg) is incorrect as it only considers the weight conversion but doesn't multiply it by the dosage. Choice D (30 mg) is incorrect as it miscalculates the dosage by not dividing the total daily dose into 2 equal parts.

Correct Answer: D

Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.

Correct Answer: C

Rationale: The correct answer is C: Promotes RBC production. Epoetin alfa stimulates erythropoiesis (red blood cell production) to treat anemia associated with chronic kidney failure. This helps in increasing the hemoglobin levels and improving oxygen-carrying capacity. Choices A, B, and D are incorrect as epoetin alfa does not have direct effects on reducing blood pressure, inhibiting clotting of the fistula, or stimulating the growth of neutrophils.
