Correct Answer: C

Rationale: Choice C indicates a need for further teaching because stating 'I can eat unlimited fruit as it is healthy' is incorrect. While fruits are healthy, they also contain natural sugars that can affect blood glucose levels. Portion control is crucial to managing blood glucose levels effectively. Choices A, B, and D demonstrate correct understanding. Rotating insulin injection sites helps prevent tissue damage, monitoring blood glucose levels before meals aids in managing diabetes effectively, and carrying a fast-acting carbohydrate is essential to treat hypoglycemia promptly.

Correct Answer: B

Rationale: The correct answer is B: Amiodarone. Amiodarone can affect thyroid function and potentially worsen hypothyroidism, so its use should be carefully considered or questioned in clients with this condition. Levothyroxine (Choice A) is the mainstay therapy for hypothyroidism and should not be questioned in this scenario. Calcium supplements (Choice C) are not typically contraindicated in clients with hypothyroidism and may be needed if there is a deficiency. Aspirin (Choice D) is not directly related to thyroid function and is not a medication that would typically be questioned in a client with hypothyroidism.

Correct Answer: C

Rationale: Instructing the client on appropriate fluid restrictions is a nursing intervention that requires professional judgment and should be performed by the nurse. In this scenario, the nurse should provide education regarding fluid restrictions based on the client's individual needs. Measuring the client's output from the indwelling catheter (choice A) and recording intake and output (choice B) can be tasks delegated to the unlicensed nursing assistant. Providing water for a client diagnosed with diabetes insipidus (choice D) is not appropriate as these clients often require careful fluid management to prevent complications.

Correct Answer: D

Rationale: The correct intervention for a client with syndrome of inappropriate antidiuretic hormone (SIADH) is to restrict oral fluids. SIADH leads to excessive release of antidiuretic hormone (ADH), causing the body to retain water and diluting the sodium levels in the blood (hyponatremia). Restricting oral fluids helps prevent further water retention and worsening hyponatremia. Encouraging increased fluid intake (choice A) would exacerbate the problem by further diluting sodium levels. Administering vasopressin (choice B) is not indicated in SIADH, as the condition is characterized by excess ADH secretion. Monitoring for signs of dehydration (choice C) is not the priority in SIADH since the issue is water retention rather than dehydration.

Correct Answer: B

Rationale: The correct answer is B: Hyponatremia. Syndrome of inappropriate antidiuretic hormone (SIADH) is characterized by the excessive release of antidiuretic hormone (ADH), leading to water retention in the body. This causes dilutional hyponatremia, where the sodium levels in the blood become abnormally low. Option A, Hypernatremia, is incorrect because SIADH does not cause elevated sodium levels. Option C, Hyperkalemia, is incorrect as SIADH does not directly affect potassium levels. Option D, Hypercalcemia, is also incorrect as SIADH does not impact calcium levels.
