Nursing Elites

1. The healthcare professional is educating a client with Cushing's syndrome about dietary management. Which of the following instructions should the healthcare professional include?

• A. Increase sodium intake
• B. Limit protein intake
• C. Limit calcium intake
• D. Increase potassium intake

Correct answer: D

Rationale: For clients with Cushing's syndrome, they are at risk of developing hypokalemia due to increased excretion of potassium. Therefore, it is essential to advise them to increase their potassium intake. Choices A, B, and C are incorrect because: A) Increasing sodium intake can worsen fluid retention and hypertension common in Cushing's syndrome. B) Limiting protein intake is not necessary unless there are specific kidney issues that require protein restriction. C) Limiting calcium intake is not typically recommended unless there are underlying conditions such as hypercalcemia.

2. 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.

3. A client with hyperaldosteronism is at risk for which of the following electrolyte imbalances?

• A. Hyperkalemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypercalcemia

Correct answer: C

Rationale: In hyperaldosteronism, there is an excessive secretion of aldosterone, a hormone that promotes potassium excretion in the kidneys. This leads to low potassium levels in the blood, known as hypokalemia. Therefore, the correct answer is hypokalemia (Choice C). Hyperkalemia (Choice A) is the opposite condition, where there is high potassium levels in the blood and is not typically associated with hyperaldosteronism. Hyponatremia (Choice B) is a low sodium level, which is not directly related to aldosterone function. Hypercalcemia (Choice D) is an elevated calcium level and is not typically a direct result of hyperaldosteronism.

4. A client with type 1 diabetes mellitus is experiencing hypoglycemia. What should the nurse instruct the client to do?

• A. Administer insulin immediately
• B. Consume 15 grams of simple carbohydrates
• C. Drink plenty of water
• D. Avoid eating until symptoms resolve

Correct answer: B

Rationale: When a client with type 1 diabetes mellitus experiences hypoglycemia, the nurse should instruct them to consume 15 grams of simple carbohydrates. This is the recommended initial treatment for hypoglycemia as it helps quickly raise blood sugar levels to alleviate symptoms and prevent complications. Administering insulin immediately (Choice A) would further lower blood sugar levels, worsening the hypoglycemia. Drinking plenty of water (Choice C) and avoiding eating until symptoms resolve (Choice D) are not appropriate actions for treating hypoglycemia as they do not address the immediate need to raise blood sugar levels.

5. An incoherent female client with a history of hypothyroidism is brought to the emergency department by the rescue squad. Physical and laboratory findings reveal hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area. Knowing that these findings suggest severe hypothyroidism, Nurse Libby prepares to take emergency action to prevent the potential complication of:

• A. Thyroid storm.
• B. Cretinism.
• C. Myxedema coma.
• D. Hashimoto's thyroiditis.

Correct answer: C

Rationale: The scenario described with hypothermia, hypoventilation, respiratory acidosis, bradycardia, hypotension, and nonpitting edema of the face and pretibial area is indicative of myxedema coma, a severe and life-threatening complication of hypothyroidism. Myxedema coma requires immediate emergency treatment to prevent further deterioration. Choice A, thyroid storm, is a complication of hyperthyroidism characterized by an increase in body temperature, heart rate, and blood pressure. Choice B, cretinism, refers to untreated congenital hypothyroidism leading to mental and physical growth retardation. Choice D, Hashimoto's thyroiditis, is an autoimmune condition leading to hypothyroidism but does not present with the acute, life-threatening symptoms described in the scenario.
