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. The client with DM who is taking insulin develops a fever and becomes confused. Which action should the nurse take first?
- A. Check the client's blood glucose level.
- B. Administer a fever-reducing medication.
- C. Give the client fluids to drink.
- D. Notify the health care provider.
Correct answer: A
Rationale: In a client with diabetes mellitus (DM) taking insulin, the development of fever and confusion may indicate hyperglycemia or diabetic ketoacidosis. Checking the blood glucose level is the priority action in this situation. This will help determine if the symptoms are related to high blood sugar levels, guiding further interventions. Administering a fever-reducing medication (choice B) addresses only the symptom of fever and does not address the underlying cause. Providing fluids to drink (choice C) is important but should come after addressing the potential hyperglycemia or diabetic ketoacidosis. Notifying the health care provider (choice D) can be important, but immediate action to evaluate and manage the client's condition should precede contacting the provider.
3. A client with hypothyroidism is prescribed levothyroxine. The nurse should teach the client to take this medication:
- A. With meals
- B. Before bedtime
- C. On an empty stomach in the morning
- D. With a glass of milk
Correct answer: C
Rationale: Levothyroxine should be taken on an empty stomach in the morning to enhance absorption and efficacy. Taking it with meals (Choice A) may interfere with absorption due to food interactions. Taking it before bedtime (Choice B) can lead to difficulties with absorption and may disrupt the sleep cycle. Consuming levothyroxine with a glass of milk (Choice D) is not recommended as calcium in milk can interfere with its absorption. Therefore, the best practice is to take levothyroxine on an empty stomach in the morning to ensure optimal effectiveness.
4. A client with Graves' disease is prescribed propranolol. The nurse understands that the purpose of this medication is to:
- A. Treat the underlying cause of the disease
- B. Reduce thyroid hormone production
- C. Alleviate symptoms such as tachycardia and tremors
- D. Increase energy levels
Correct answer: C
Rationale: The correct answer is C: Alleviate symptoms such as tachycardia and tremors. Propranolol is a beta-blocker that helps manage symptoms like tachycardia (fast heart rate) and tremors in patients with Graves' disease. Choice A is incorrect because propranolol does not address the underlying cause of Graves' disease, which is autoimmune in nature. Choice B is incorrect because propranolol does not directly reduce thyroid hormone production; it mainly targets the symptoms. Choice D is incorrect because while propranolol may help with symptoms like tachycardia, it is not intended to increase energy levels.
5. How often should rotation sites for insulin injection be separated from one another?
- A. Every third day.
- B. Every week.
- C. Every 2-3 weeks.
- D. Every 2-4 weeks.
Correct answer: C
Rationale: Insulin injection sites should be rotated every 2-3 weeks to prevent lipodystrophy and ensure proper insulin absorption. Option A ('Every third day') is too frequent and does not allow enough time for the previous site to heal properly. Option B ('Every week') might not provide adequate time for the tissue to recover. Option D ('Every 2-4 weeks') could potentially lead to overuse of a single injection site, increasing the risk of lipodystrophy and inconsistent insulin absorption. Therefore, the recommended interval of every 2-3 weeks is optimal for insulin injection site rotation.
