1. A client with type 1 DM calls the nurse to report recurrent episodes of hypoglycemia with exercise. Which statement by the client indicates an inadequate understanding of the peak action of NPH insulin and exercise?

• A. The best time for me to exercise is every afternoon.
• B. The best time for me to exercise is right after I eat.
• C. The best time for me to exercise is after breakfast.
• D. The best time for me to exercise is after my morning snack.

Correct answer: A

Rationale: Exercising in the afternoon may coincide with the peak action of NPH insulin, increasing the risk of hypoglycemia. The peak action of NPH insulin typically occurs 4-12 hours after administration, so exercising during this time can further lower blood sugar levels. Choices B, C, and D are better options as they suggest exercising at times that are less likely to overlap with the peak insulin action, reducing the risk of hypoglycemia.

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. When teaching a male client diagnosed with type 1 diabetes mellitus how diet and exercise affect insulin requirements, Nurse Joy should include which guideline?

• A. You'll need more insulin when you exercise or increase your food intake.
• B. You'll need less insulin when you exercise or reduce your food intake.
• C. You'll need less insulin when you increase your food intake.
• D. You'll need more insulin when you exercise or decrease your food intake.

Correct answer: B

Rationale: When a person with type 1 diabetes exercises, it typically lowers blood glucose levels. As a result, insulin needs are reduced when exercise or food intake is decreased. Choice A is incorrect because more insulin is not typically needed when exercise or food intake is increased. Choice C is incorrect because increasing food intake would generally require more insulin to cover the additional glucose from the food. Choice D is incorrect as decreasing food intake usually leads to a lower need for insulin.

4. A client with hyperparathyroidism is at risk for which of the following complications?

• A. Hypocalcemia
• B. Osteoporosis
• C. Hypokalemia
• D. Hyponatremia

Correct answer: B

Rationale: A client with hyperparathyroidism is at risk for osteoporosis, not hypocalcemia, hypokalemia, or hyponatremia. Hyperparathyroidism results in increased levels of parathyroid hormone, which causes excessive breakdown of bone tissue to release calcium into the bloodstream. This process can lead to weakened bones and an increased risk of osteoporosis. Hypocalcemia is unlikely in hyperparathyroidism as the condition is characterized by elevated calcium levels due to the abnormal activity of the parathyroid glands. Hypokalemia and hyponatremia are not directly associated with hyperparathyroidism; they are more commonly linked to other conditions affecting potassium and sodium levels in the body.

5. The healthcare provider is monitoring a client with diabetic ketoacidosis (DKA). Which of the following laboratory findings would be expected?

• A. Decreased blood glucose levels
• B. Decreased urine ketones
• C. Increased serum bicarbonate
• D. Increased anion gap

Correct answer: D

Rationale: In diabetic ketoacidosis (DKA), there is an excess of ketone bodies produced due to the breakdown of fatty acids for energy, leading to metabolic acidosis. An increased anion gap is a characteristic laboratory finding in DKA. The increased anion gap is a result of the accumulation of ketoacids and lactic acid in the blood, contributing to metabolic acidosis. Therefore, the correct answer is an increased anion gap. Choices A, B, and C are incorrect because in DKA, blood glucose levels are typically elevated, urine ketones are increased due to the breakdown of fatty acids, and serum bicarbonate is usually decreased as it is consumed in an attempt to buffer the acidosis.
