A patient has just begun taking calcitriol. Which nursing implication would the nurse do?

Correct Answer: B

Rationale: Rationale: B: Monitoring serum calcium levels is crucial when a patient starts taking calcitriol to prevent hypercalcemia or hypocalcemia. This is because calcitriol regulates calcium absorption. Weight monitoring (A) may not be directly related. Teaching side effects (C) is important but not specific to calcitriol.

Correct Answer: D

Rationale: The correct answer is D because rinsing the mouth after taking oral nitrofurantoin helps prevent staining of the teeth. Nitrofurantoin can cause teeth discoloration, so rinsing the mouth is essential to minimize this side effect. Choice A is incorrect because nitrofurantoin does not affect urine color. Choice C is incorrect because maintaining acidic urine is not necessary for nitrofurantoin therapy. Choice B is irrelevant as it is incomplete.

Correct Answer: D

Rationale: The correct answer is D because both Tolbutamide (A) and Repaglinide (B) act by blocking ATP sensitive K+ channels on pancreatic beta cells, leading to insulin secretion. Tolbutamide is a sulfonylurea, while Repaglinide is a meglitinide. Ciglitazone (C) is a thiazolidinedione that works by increasing insulin sensitivity in peripheral tissues, not by blocking ATP-sensitive K+ channels. Therefore, choices A, B, and C are incorrect as they do not directly block ATP-sensitive K+ channels.

Correct Answer: D

Rationale: The correct answer is D, Radioactive iodine. Radioactive iodine is contraindicated in pregnant women due to its teratogenic effects on the developing fetus. It can cause fetal thyroid dysfunction and increase the risk of thyroid cancer later in life. Sodium iodide (A) and potassium iodide (C) are safe to use in pregnancy for managing thyrotoxicosis. Propylthiouracil (B) is also considered safe and is often the preferred treatment choice in pregnant women.

Correct Answer: C

Rationale: The correct answer is C: Chlorpropamide. It is a sulfonylurea drug that can be used to treat Diabetes insipidus by increasing the release of antidiuretic hormone (ADH) from the pituitary gland, thereby reducing excessive urination. Voglibose (A) is an alpha-glucosidase inhibitor used for diabetes mellitus. Metformin (B) is a biguanide used for type 2 diabetes. Pioglitazone (D) is a thiazolidinedione also used for type 2 diabetes but not for Diabetes insipidus.
