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. Jemma, who weighs 210 lb (95 kg) and has been diagnosed with hyperglycemia tells the nurse that her husband sleeps in another room because her snoring keeps him awake. The nurse notices that she has large hands and a hoarse voice. Which of the following would the nurse suspect as a possible cause of the client's hyperglycemia?

• A. Acromegaly
• B. Type 1 diabetes mellitus
• C. Hypothyroidism
• D. Deficient growth hormone

Correct answer: A

Rationale: The correct answer is Acromegaly. Jemma's symptoms of large hands, hoarse voice, and snoring are indicative of acromegaly, a disorder caused by excessive growth hormone production. Acromegaly can lead to insulin resistance, which can result in hyperglycemia. Choice B, Type 1 diabetes mellitus, is unlikely in this case as the symptoms and presentation are more suggestive of acromegaly. Choice C, Hypothyroidism, typically presents with different symptoms such as weight gain, fatigue, and cold intolerance, not consistent with Jemma's symptoms. Choice D, Deficient growth hormone, would not lead to the signs and symptoms observed in Jemma, as her condition is characterized by excessive growth hormone production.

3. A client with Cushing's syndrome is being monitored for complications. Which of the following findings should the nurse report to the healthcare provider immediately?

• A. Hypertension
• B. Hyperglycemia
• C. Low-grade fever
• D. Weight gain

Correct answer: C

Rationale: The correct answer is C: Low-grade fever. A low-grade fever may indicate an infection, which is a serious concern in clients with Cushing's syndrome due to their immunosuppressed state. Hypertension and hyperglycemia are common manifestations of Cushing's syndrome and may not require immediate reporting unless severe or uncontrolled. Weight gain is also a common symptom in clients with Cushing's syndrome and may not warrant immediate reporting unless it is sudden and significant.

4. A client is taking NPH insulin daily every morning. The nurse instructs the client that the most likely time for a hypoglycemic reaction to occur is:

• A. 2-4 hours after administration
• B. 6-14 hours after administration
• C. 16-18 hours after administration
• D. 18-24 hours after administration

Correct answer: B

Rationale: The correct answer is B: 6-14 hours after administration. NPH insulin has an onset of action within 1-2 hours, a peak action at 6-14 hours, and a duration of action of 16-24 hours. The peak action period, which is when the risk of hypoglycemia is highest, falls between 6-14 hours after administration. Choices A, C, and D are incorrect because they do not align with the typical action profile of NPH insulin.

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.
