Correct Answer: D

Rationale: Pheochromocytoma is a tumor of the adrenal medulla that secretes excessive catecholamines, leading to symptoms such as hypertension. The normal blood pressure range is around 120/80 mm Hg, so a blood pressure reading of 176/88 mm Hg is most likely to be detected in a client with pheochromocytoma. Choices A, B, and C are incorrect because pheochromocytoma typically presents with hypertension, not a normal or low blood pressure (choice A), not related to blood glucose levels (choice B), and not bradycardia (choice C).

Correct Answer: C

Rationale: The correct answer is C: 'Monitoring.' Monitoring involves regularly checking and observing the status of a unit or situation. In this scenario, the nurse manager is actively seeking feedback from staff members to assess and keep track of the staffing situation. Choice A, 'Spokesperson,' refers to a role where someone represents or speaks on behalf of a group or organization, which is not the primary activity in this case. Choice B, 'Reporting,' typically involves presenting information or data about a specific topic or issue but does not capture the ongoing observation and assessment aspect seen in monitoring. Choice D, 'Job analysis and redesign,' involves assessing and restructuring job roles, responsibilities, and tasks, which is not directly related to the action of monitoring staffing levels.

Correct Answer: A

Rationale: Administering insulin intravenously is the priority action for managing diabetic ketoacidosis. Insulin helps lower blood glucose levels and halts the production of ketones, addressing the underlying cause of ketoacidosis. Giving sips of water (Choice B) may be necessary for hydration, but it does not address the immediate life-threatening issue of ketoacidosis. Monitoring urine output (Choice C) is important for assessing renal function but is not the priority over administering insulin. Applying a heating pad (Choice D) is not indicated and can potentially worsen the condition in ketoacidosis.

Correct Answer: B

Rationale: The correct first intervention in the treatment of a client with diabetic ketoacidosis (DKA) is to start an intravenous line and infuse normal saline. This is essential for fluid resuscitation to restore intravascular volume and improve perfusion. Administering intravenous insulin can lead to further potassium depletion without first addressing dehydration and electrolyte imbalances. Monitoring serum potassium levels is important but should follow fluid resuscitation to avoid life-threatening hypokalemia. Obtaining an arterial blood gas (ABG) is necessary to assess the acid-base status but is not the initial priority when managing DKA.

Correct Answer: C

Rationale: Cold intolerance is a classic symptom of hypothyroidism. In hypothyroidism, the body's metabolic rate is decreased, leading to a reduced ability to regulate body temperature. As a result, individuals with hypothyroidism often feel cold, especially in their extremities. Tachycardia (A) is more commonly associated with hyperthyroidism due to the increased metabolic rate. Weight loss (B) is also a typical finding in hyperthyroidism, as the body burns calories at a faster rate. Diaphoresis (D), excessive sweating, is not a typical symptom of hypothyroidism.
