Leadership and Management HESI

Correct Answer: B

Rationale: Hyperparathyroidism leads to increased secretion of parathyroid hormone, which results in elevated calcium levels in the blood (hypercalcemia). Therefore, the correct lab finding consistent with hyperparathyroidism is hypercalcemia (Choice B). Hypocalcemia (Choice A) is not indicative of hyperparathyroidism as the condition is associated with high calcium levels. Hypokalemia (Choice C) is a low potassium level, which is not typically associated with hyperparathyroidism. Hyperphosphatemia (Choice D) refers to high phosphate levels and is not a characteristic finding in hyperparathyroidism.

Correct Answer: A

Rationale: Prednisone, a corticosteroid, can increase blood glucose levels by promoting gluconeogenesis and decreasing glucose uptake by cells. This medication can lead to hyperglycemia in patients, especially those with diabetes mellitus. Atenolol (Tenormin) is a beta-blocker and is not known to significantly affect blood glucose levels. Phenelzine (Nardil) is a monoamine oxidase inhibitor used to treat depression and anxiety disorders; it does not typically impact blood glucose levels. Allopurinol (Zyloprim) is a xanthine oxidase inhibitor used to manage gout and does not interfere with blood glucose regulation.

Correct Answer: D

Rationale: Polyuria, polydipsia, and polyphagia are classic signs of hyperglycemia, indicating high blood glucose levels. The priority action for the nurse is to check the client's blood glucose levels to assess the severity of hyperglycemia and determine the need for appropriate interventions. Administering insulin (Choice A) may be necessary based on the blood glucose levels but should only be done after confirming the current status. Encouraging increased fluid intake (Choice B) may exacerbate the symptoms by further diluting the blood glucose concentration. While monitoring for signs of dehydration (Choice C) is important in the long term, the immediate action should focus on determining the blood glucose levels first.

Correct Answer: A

Rationale: The priority nursing diagnosis for a client with Addison's disease is 'Fluid volume deficit.' Addison's disease is characterized by adrenal insufficiency, resulting in decreased aldosterone production. Aldosterone plays a key role in sodium and water retention in the body. With its deficiency, there is an increased risk of dehydration and electrolyte imbalance, leading to fluid volume deficit. While infection risk, nutrition issues, and body image disturbances are also important considerations for holistic care, addressing the fluid volume deficit takes precedence due to the immediate physiological impact on the client's health and well-being.

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).
