1. A client with Addison's disease is at risk for which of the following complications?

• A. Hypertension
• B. Hypovolemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: B

Rationale: A client with Addison's disease is at risk for hypovolemia. Addison's disease is characterized by adrenal insufficiency, particularly cortisol and aldosterone deficiency. Aldosterone deficiency leads to impaired sodium and water retention, resulting in decreased blood volume and hypovolemia. This condition can cause hypotension, not hypertension (Choice A), as reduced blood volume leads to decreased pressure. Hypernatremia (Choice C) is unlikely in Addison's disease because of the loss of sodium along with water in hypovolemia. Hypokalemia (Choice D) can occur due to aldosterone deficiency, but it is not the primary complication associated with Addison's disease.

2. Nurse Louie is developing a teaching plan for a male client diagnosed with diabetes insipidus. The nurse should include information about which hormone lacking in clients with diabetes insipidus?

• A. Antidiuretic hormone (ADH)
• B. Thyroid-stimulating hormone (TSH)
• C. Follicle-stimulating hormone (FSH)
• D. Luteinizing hormone (LH)

Correct answer: A

Rationale: Diabetes insipidus is a condition characterized by a deficiency of antidiuretic hormone (ADH). ADH plays a crucial role in regulating water balance by controlling the amount of water reabsorbed by the kidneys. Options B, C, and D are incorrect as they are not associated with diabetes insipidus. TSH (thyroid-stimulating hormone) is responsible for regulating thyroid function, while FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are involved in reproductive functions.

3. An external insulin pump is prescribed for a client with DM. The client asks the nurse about the functioning of the pump. The nurse bases the response on the information that the pump:

• A. Gives small continuous doses of regular insulin subcutaneously, and the client can self-administer a bolus with an additional dosage from the pump before each meal.
• B. Is timed to release programmed doses of regular or NPH insulin into the bloodstream at specific intervals.
• C. Is surgically attached to the pancreas and infuses regular insulin into the pancreas, which in turn releases the insulin into the bloodstream.
• D. Continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels.

Correct answer: A

Rationale: The correct answer is A. An external insulin pump delivers small continuous doses of regular insulin subcutaneously throughout the day to meet the basal insulin needs. The client can also self-administer a bolus dose with an additional dosage from the pump before each meal to cover the mealtime insulin needs. Option B is incorrect as insulin pumps do not typically release programmed doses of insulin into the bloodstream at specific intervals; instead, they infuse insulin subcutaneously. Option C is incorrect as insulin pumps are not surgically attached to the pancreas; they are worn externally. Option D is incorrect as NPH insulin is not commonly used in insulin pumps, and the pumps do not continuously infuse insulin directly into the bloodstream but rather subcutaneously.

4. A nurse is preparing to administer NPH insulin to a client with DM. The nurse notes that the NPH insulin vial is cloudy. The nurse should:

• A. Obtain a new vial of NPH insulin.
• B. Draw up the cloudy insulin as ordered.
• C. Shake the vial vigorously before drawing up the insulin.
• D. Warm the insulin to room temperature before administration.

Correct answer: B

Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.

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.
