1. A client with hyperthyroidism is prescribed propranolol. The nurse explains that this medication is used to:

• A. Increase thyroid hormone production
• B. Decrease thyroid hormone production
• C. Relieve symptoms such as tachycardia and anxiety
• D. Prevent weight loss

Correct answer: C

Rationale: Propranolol is a beta-blocker that works by blocking the effects of adrenaline, which helps to reduce symptoms such as tachycardia (fast heart rate) and anxiety in individuals with hyperthyroidism. Choices A and B are incorrect because propranolol does not affect thyroid hormone production; it only addresses symptoms. Choice D is incorrect because propranolol does not prevent weight loss associated with hyperthyroidism.

2. A nurse caring for a group of clients reviews the electrolyte laboratory results and notes a potassium level of 5.5 mEq/L on one client's laboratory report. The nurse understands that which client is at highest risk for the development of a potassium value at this level?

• A. The client with colitis
• B. The client with Cushing's syndrome
• C. The client who has been overusing laxatives
• D. The client who has sustained a traumatic burn

Correct answer: D

Rationale: Clients who have sustained traumatic burns are at a higher risk of developing hyperkalemia due to cell lysis. When cells are damaged in a traumatic burn, potassium can leak out from the intracellular space into the bloodstream, leading to elevated serum potassium levels. Colitis, Cushing's syndrome, and overuse of laxatives are not typically associated with the same degree of cell damage or potassium shifts seen in traumatic burns, making them less likely to result in such high potassium levels.

3. A client with hypothyroidism is being treated with levothyroxine. Which of the following symptoms would indicate that the client may be receiving too much medication?

• A. Bradycardia
• B. Weight gain
• C. Tachycardia
• D. Cold intolerance

Correct answer: C

Rationale: Tachycardia is a sign of excessive thyroid hormone replacement. Levothyroxine is used to treat hypothyroidism by supplementing thyroid hormone levels. If a client with hypothyroidism experiences symptoms of tachycardia, it suggests that they may be receiving an excessive amount of levothyroxine, causing hyperthyroidism. Bradycardia (Choice A) is more commonly associated with hypothyroidism, not excessive levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also typical symptoms of hypothyroidism and would not typically indicate overmedication.

4. A patient with acute congestive heart failure is receiving high doses of a diuretic. On assessment, the nurse notes flat neck veins, generalized muscle weakness, and diminished deep tendon reflexes. Suspecting hyponatremia, what additional signs would the nurse expect to note in this patient if hyponatremia were present?

• A. Dry skin
• B. Decreased urinary output
• C. Hyperactive bowel sounds
• D. Increased specific gravity of the urine

Correct answer: C

Rationale: In a patient with hyponatremia, hyperactive bowel sounds are expected due to increased gastrointestinal motility. Dry skin (Choice A) is not a typical sign of hyponatremia. Decreased urinary output (Choice B) is more commonly associated with conditions like dehydration or renal issues, not specifically hyponatremia. Increased specific gravity of the urine (Choice D) is a sign of concentrated urine, which is not a characteristic finding in hyponatremia.

5. After taking glipizide (Glucotrol) for 9 months, a male client experiences secondary failure. What would the nurse expect the physician to do?

• A. Initiate insulin therapy.
• B. Switch the client to a different oral antidiabetic agent.
• C. Prescribe an additional oral antidiabetic agent.
• D. Restrict carbohydrate intake to less than 30% of the total caloric intake.

Correct answer: A

Rationale: When a client experiences secondary failure to an oral antidiabetic agent like glipizide, the next step is often to initiate insulin therapy. This is because secondary failure indicates that the current oral antidiabetic medication is no longer effective in managing blood glucose levels, and insulin therapy may be required to adequately control blood sugar. Switching to a different oral antidiabetic agent may not be effective if there is already resistance to the current agent. Adding another oral antidiabetic agent may not address the underlying issue of secondary failure. Restricting carbohydrate intake is important for diabetes management but is not the primary intervention indicated in this scenario of secondary failure to glipizide.
