Nursing Elites

1. The client has hyperparathyroidism. Which of the following lab findings is consistent with this condition?

• A. Hypocalcemia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hyperphosphatemia

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.

2. A client with type 1 diabetes mellitus is admitted with diabetic ketoacidosis (DKA). Which of the following interventions should be the nurse's priority?

• A. Administer intravenous insulin
• B. Start an intravenous line and infuse normal saline
• C. Monitor serum potassium levels
• D. Obtain an arterial blood gas (ABG)

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.

3. The nurse is caring for a client with a history of adrenal insufficiency. The nurse should monitor for which of the following signs of an Addisonian crisis?

• A. Hypertension
• B. Hyperglycemia
• C. Severe hypotension
• D. Tachycardia

Correct answer: C

Rationale: In an Addisonian crisis, there is a lack of adrenal hormones leading to severe hypotension. Hypertension (choice A) is not a typical sign of Addisonian crisis but can occur in conditions like pheochromocytoma. Hyperglycemia (choice B) is not a characteristic sign of an Addisonian crisis. Tachycardia (choice D) may occur as a compensatory mechanism in response to hypotension, but severe bradycardia is more common in an Addisonian crisis.

4. Early this morning, a female client had a subtotal thyroidectomy. During evening rounds, Nurse Tina assesses the client, who now has nausea, a temperature of 105°F (40.5°C), tachycardia, and extreme restlessness. What is the most likely cause of these signs?

• A. Diabetic ketoacidosis
• B. Thyroid crisis
• C. Hypoglycemia
• D. Tetany

Correct answer: B

Rationale: The correct answer is B: Thyroid crisis. Thyroid crisis, also known as thyroid storm, is a life-threatening condition that can occur after a thyroidectomy. Symptoms include high fever, tachycardia, extreme restlessness, and other signs of severe hyperthyroidism. Diabetic ketoacidosis (choice A) is a complication of diabetes characterized by hyperglycemia, ketosis, and acidosis, not typically seen post-thyroidectomy. Hypoglycemia (choice C) is low blood sugar levels and would not present with the symptoms described. Tetany (choice D) is a condition of involuntary muscle spasms due to low calcium levels and is not directly related to the symptoms observed in this scenario.

5. What is the mechanism of action of corticotropin (Acthar) when prescribed as replacement therapy for a male client who has undergone surgical removal of a pituitary tumor?

• A. It decreases cyclic adenosine monophosphate (cAMP) production and affects the metabolic rate of target organs.
• B. It interacts with plasma membrane receptors to inhibit enzymatic actions.
• C. It interacts with plasma membrane receptors to produce enzymatic actions that affect protein, fat, and carbohydrate metabolism.
• D. It regulates the threshold for water reabsorption in the kidneys.

Correct answer: C

Rationale: Corticotropin (ACTH) stimulates the adrenal cortex to secrete cortisol and other hormones, affecting protein, fat, and carbohydrate metabolism. Choice A is incorrect because corticotropin does not decrease cAMP production; instead, it stimulates enzymatic actions. Choice B is incorrect because corticotropin does not inhibit enzymatic actions but rather produces enzymatic actions. Choice D is incorrect because corticotropin's mechanism of action does not involve regulating the threshold for water reabsorption in the kidneys.
