Correct Answer: B

Rationale: Neck vein distention is a sign of fluid overload, a complication of SIADH due to water retention. Tetanic contractions (Choice A) are not typically associated with SIADH. Weight loss (Choice C) is not a common complication of SIADH, as patients often experience fluid retention and weight gain. Polyuria (Choice D) is also not a typical sign of SIADH, as the condition is characterized by water retention and decreased urine output.

Correct Answer: B

Rationale: Nonmaleficence is the ethical principle of doing no harm. In nursing practice, ensuring that a patient does not receive a treatment they have refused is an example of nonmaleficence. Choice A focuses on beneficence by providing pain relief. Choice C is more aligned with beneficence as it emphasizes providing appropriate care without harm. Choice D pertains to patient communication but does not directly address the concept of nonmaleficence.

Correct Answer: B

Rationale: Puffiness of the face and hands is a classic symptom of hypothyroidism. This occurs due to fluid retention and is commonly observed in individuals with an underactive thyroid gland. Increased appetite and weight loss (Choice A) are more indicative of hyperthyroidism, where there is an overproduction of thyroid hormones leading to increased metabolism. Nervousness and tremors (Choice C) are associated with hyperthyroidism, not hypothyroidism. Thyroid gland swelling (Choice D) typically indicates goiter, which can be present in both hyperthyroidism and hypothyroidism but is not a specific symptom that clients with hypothyroidism commonly report.

Correct Answer: C

Rationale: The correct answer is to 'Increase fluid intake.' This is because increasing fluid intake helps prevent kidney stones, a common complication of hyperparathyroidism. While calcium is involved in the condition, increasing calcium intake is not recommended as it can exacerbate hypercalcemia, which is commonly present in hyperparathyroidism. Limiting phosphorus intake is not directly related to managing hyperparathyroidism. Limiting vitamin D intake is also not typically necessary in managing hyperparathyroidism, as it is usually a calcium and PTH-related issue.

Correct Answer: B

Rationale: The correct answer is to start an intravenous line and infuse normal saline. In diabetic ketoacidosis (DKA), the priority intervention is fluid resuscitation with normal saline to restore intravascular volume and improve perfusion. Administering insulin without first addressing dehydration and electrolyte imbalances can lead to further complications. Monitoring serum potassium levels and obtaining an arterial blood gas (ABG) are important aspects of DKA management but come after initial fluid resuscitation.
