Nursing Elites

1. 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.

2. A client with diabetes insipidus is being treated with desmopressin. The nurse should monitor for which of the following side effects?

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

Correct answer: A

Rationale: The correct answer is A: Hyponatremia. Desmopressin, a medication used in diabetes insipidus, can cause water retention by increasing water reabsorption in the kidneys. This excess water retention can lead to dilutional hyponatremia, where sodium levels in the body become too low. Monitoring for hyponatremia is crucial to prevent complications such as neurological symptoms. Choices B, C, and D are incorrect because desmopressin is not known to cause hypernatremia, hypokalemia, or hypercalcemia.

3. For a diabetic male client with a foot ulcer, the physician orders bed rest, a wet-to-dry dressing change every shift, and blood glucose monitoring before meals and bedtime. Why are wet-to-dry dressings used for this client?

• A. They contain exudate and provide a moist wound environment.
• B. They protect the wound from mechanical trauma and promote healing.
• C. They debride the wound and promote healing by secondary intention.
• D. They prevent the entrance of microorganisms and minimize wound discomfort.

Correct answer: C

Rationale: Wet-to-dry dressings are utilized in this case to debride the wound by removing dead tissue and promoting healing by secondary intention. Choice A is incorrect as wet-to-dry dressings do not provide a moist wound environment; instead, they promote drying to aid in debridement. Choice B is incorrect because their primary purpose is not to protect the wound but to remove dead tissue. Choice D is incorrect as the main function of wet-to-dry dressings is not to prevent the entrance of microorganisms or minimize wound discomfort.

4. Acarbose (Precose), an alpha-glucosidase inhibitor, is prescribed for a female client with type 2 diabetes mellitus. During discharge planning, nurse Pauleen would be aware of the client's need for additional teaching when the client states:

• A. If I have hypoglycemia, I should eat some sugar, not dextrose.
• B. The drug makes my pancreas release more insulin.
• C. I should never take insulin while I'm taking this drug.
• D. It's best if I take the drug with the first bite of a meal.

Correct answer: B

Rationale: The correct answer is B. Acarbose (Precose) is an alpha-glucosidase inhibitor that works by slowing carbohydrate absorption in the intestine, not by stimulating insulin release. Therefore, the client would need additional teaching if they state that the drug makes their pancreas release more insulin (Choice B). Choices A, C, and D are incorrect. Choice A is incorrect because during hypoglycemia, it is recommended to consume glucose or dextrose to rapidly raise blood sugar levels. Choice C is incorrect because insulin therapy may still be needed in some cases, even when taking acarbose. Choice D is incorrect because acarbose should be taken at the start of a meal to help reduce postprandial blood glucose levels.

5. 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.
