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. Albert refuses his bedtime snack. This should alert the healthcare provider to assess for:

• A. Elevated serum bicarbonate and decreased blood pH.
• B. Signs of hypoglycemia earlier than expected.
• C. Symptoms of hyperglycemia due to NPH insulin peak time.
• D. Presence of sugar in the urine.

Correct answer: B

Rationale: When a patient like Albert refuses his bedtime snack, it can lead to hypoglycemia, especially if they are on medication such as insulin. Hypoglycemia can occur earlier than expected due to the lack of carbohydrate intake before bedtime. This situation warrants the healthcare provider to monitor for signs and symptoms of hypoglycemia. Choice A is incorrect because the given scenario is more indicative of hypoglycemia than metabolic alkalosis. Choice C is incorrect as NPH insulin peak time is not directly related to skipping a bedtime snack. Choice D is incorrect as sugar in the urine typically indicates hyperglycemia, not hypoglycemia.

3. A client with Addison's disease is being educated about managing the condition during times of stress. The nurse should instruct the client to:

• A. Double the dose of corticosteroids during periods of stress.
• B. Skip the dose of corticosteroids if you feel well.
• C. Decrease fluid intake to prevent hypertension.
• D. Avoid physical activity during stressful times.

Correct answer: A

Rationale: Clients with Addison's disease should be educated to double their corticosteroid dosage during periods of stress. This is crucial to prevent adrenal crisis, as stress can increase the body's demand for cortisol. Skipping doses when feeling well can lead to an adrenal crisis if stress occurs suddenly. Decreasing fluid intake can exacerbate dehydration and electrolyte imbalances, which are already concerns in Addison's disease. Avoiding physical activity during stressful times is not the most appropriate advice; moderate physical activity can be beneficial, as long as the client is adequately managing their corticosteroid regimen.

4. A client with DM is being taught about the importance of foot care by a nurse. Which instruction should the nurse include?

• A. Use a heating pad to warm your feet.
• B. Avoid walking barefoot.
• C. Soak your feet in hot water every night.
• D. Wear tight shoes to protect your feet.

Correct answer: B

Rationale: The correct instruction for the nurse to include is to advise the client to avoid walking barefoot. This recommendation is crucial for clients with diabetes to prevent foot injuries and infections. Walking barefoot can lead to unnoticed wounds or ulcers due to reduced sensation in the feet (neuropathy) common in diabetes. Choice A is incorrect as heating pads can cause burns and should be avoided. Choice C is incorrect because soaking feet in hot water can also lead to burns and skin damage. Choice D is incorrect as tight shoes can increase the risk of pressure sores and restrict blood flow, which is detrimental for individuals with diabetes.

5. Albert, a 35-year-old insulin-dependent diabetic, is admitted to the hospital with a diagnosis of pneumonia. He has been febrile since admission. His daily insulin requirement is 24 units of NPH. Every morning Albert is given NPH insulin at 0730. Meals are served at 0830, 1230, and 1830. The nurse expects that the NPH insulin will reach its maximum effect (peak) between the hours of:

• A. 1130 and 1330.
• B. 1330 and 1930.
• C. 1530 and 2130.
• D. 1730 and 2330.

Correct answer: C

Rationale: NPH insulin typically peaks 4-12 hours after administration, so a peak between 1530 and 2130 would be expected. Choice A (1130 and 1330) is too early for the peak effect of NPH insulin. Choice B (1330 and 1930) falls within the possible peak period but is not as accurate as choice C. Choice D (1730 and 2330) is too late for the peak effect of NPH insulin based on the typical peak timing.
