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. The healthcare professional is educating a client with Cushing's syndrome about dietary management. Which of the following instructions should the healthcare professional include?

• A. Increase sodium intake
• B. Limit protein intake
• C. Limit calcium intake
• D. Increase potassium intake

Correct answer: D

Rationale: For clients with Cushing's syndrome, they are at risk of developing hypokalemia due to increased excretion of potassium. Therefore, it is essential to advise them to increase their potassium intake. Choices A, B, and C are incorrect because: A) Increasing sodium intake can worsen fluid retention and hypertension common in Cushing's syndrome. B) Limiting protein intake is not necessary unless there are specific kidney issues that require protein restriction. C) Limiting calcium intake is not typically recommended unless there are underlying conditions such as hypercalcemia.

3. A client with type 1 DM is experiencing hypoglycemia. Which symptom should the nurse expect to observe?

• A. Tachycardia
• B. Polyuria
• C. Flushed skin
• D. Dry mouth

Correct answer: A

Rationale: The correct answer is A: Tachycardia. In hypoglycemia, the body releases adrenaline in response to low blood glucose levels, leading to symptoms such as tachycardia (rapid heart rate). Choice B, polyuria, refers to excessive urination and is not a typical symptom of hypoglycemia. Choice C, flushed skin, is not a common symptom of hypoglycemia; instead, pale skin and sweating are more characteristic. Choice D, dry mouth, is not directly associated with hypoglycemia; rather, it can be a symptom of hyperglycemia or dehydration.

4. The nurse is caring for a client with congestive heart failure. On assessment, the nurse notes that the client is dyspneic and that crackles are audible on auscultation. The nurse suspects excess fluid volume. What additional signs would the nurse expect to note in this client if excess fluid volume is present?

• A. Weight loss
• B. Flat neck and hand veins
• C. An increase in blood pressure
• D. A decreased central venous pressure (CVP)

Correct answer: C

Rationale: An increase in blood pressure is a common sign of fluid volume excess in clients with congestive heart failure due to the increased amount of fluid in the vascular system. Weight loss (Choice A) is not typically associated with fluid volume excess. Flat neck and hand veins (Choice B) are signs of fluid volume deficit, not excess. A decreased central venous pressure (CVP) (Choice D) is not expected in a client with fluid volume excess.

5. Capillary glucose monitoring is being performed every 4 hours for a female client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which she receives 8 U of regular insulin. Nurse Vince should expect the dose's:

• A. Onset to be at 2 p.m. and its peak to be at 3 p.m.
• B. Onset to be at 2:15 p.m. and its peak to be at 3 p.m.
• C. Onset to be at 2:30 p.m. and its peak to be at 4 p.m.
• D. Onset to be at 4 p.m. and its peak to be at 6 p.m.

Correct answer: C

Rationale: The correct answer is C. Regular insulin typically has an onset of action within 30 minutes and peaks 2-4 hours after administration. Given that the insulin was administered at 2 p.m., the onset of action can be expected around 2:30 p.m., and the peak effect would occur between 4-6 p.m. Choice A is incorrect as the onset and peak are too close together for regular insulin. Choice B is incorrect because the onset time is too soon after administration. Choice D is incorrect as the onset time is too delayed for regular insulin.
