Nursing Elites

1. A client is scheduled to undergo computerized tomography (CT) with contrast for evaluation of an abdominal mass. The nurse should tell the client that:

• A. The test may be painful
• B. The test takes 2 to 3 hours
• C. Food and fluids are not allowed for 4 hours after the test
• D. Dye is injected and may cause a warm flushing sensation

Correct answer: D

Rationale: The correct answer is D. A contrast-aided CT scan involves the injection of dye to enhance the images obtained. The dye may cause a warm flushing sensation when injected, which is a common side effect. Choices A, B, and C are incorrect. CT with contrast is generally not a painful procedure, the duration of the test does not usually take 2 to 3 hours, and restrictions on food and fluids are typically before the test, not afterward.

2. What is the primary action of insulin in the body?

• A. To lower blood pressure.
• B. To promote the absorption of glucose into cells.
• C. To increase blood glucose levels.
• D. To decrease blood glucose levels.

Correct answer: B

Rationale: The correct answer is B: To promote the absorption of glucose into cells. Insulin facilitates the uptake of glucose by cells, thereby decreasing blood glucose levels. Choice A is incorrect as insulin does not directly affect blood pressure. Choice C is inaccurate as insulin works to lower, not increase, blood glucose levels. Choice D is incorrect because insulin's primary role is to lower, not increase, blood glucose levels by promoting glucose uptake into cells.

3. The client with chronic renal failure is being taught about fluid restrictions by the nurse. Which statement by the client indicates a need for further teaching?

• A. I can drink as much water as I want, as long as I limit my salt intake.
• B. I should limit my fluid intake to prevent fluid overload.
• C. I can skip dialysis sessions if I feel tired.
• D. I can eat whatever I want, as long as I take my medications.

Correct answer: C

Rationale: Choice C is the correct answer because clients with chronic renal failure should not skip dialysis sessions. Skipping dialysis can lead to serious complications and worsen the client's condition. It is crucial for clients to understand the importance of adhering to their dialysis schedule for optimal management of chronic renal failure. Choices A, B, and D are incorrect because they demonstrate understanding of fluid restrictions, the need to limit fluid intake to prevent overload, and the importance of medication compliance, respectively. These statements show appropriate knowledge and do not indicate a need for further teaching.

4. A client is receiving a continuous IV infusion of heparin for the treatment of deep vein thrombosis. The client’s activated partial thromboplastin time (aPTT) level is 80 seconds. The client’s baseline before the initiation of therapy was 30 seconds. Which action does the nurse anticipate is needed?

• A. Shutting off the heparin infusion
• B. Increasing the rate of the heparin infusion
• C. Decreasing the rate of the heparin infusion
• D. Leaving the rate of the heparin infusion as is

Correct answer: C

Rationale: The nurse needs to decrease the rate of the heparin infusion. The therapeutic dose of heparin for the treatment of deep vein thrombosis is designed to keep the aPTT between 1.5 and 2.5 times normal. With the client's aPTT level elevated to 80 seconds from a baseline of 30 seconds, it indicates that the current rate of heparin infusion is too high. Lowering the rate of infusion is necessary to bring the aPTT within the desired therapeutic range. Choices A, B, and D are incorrect because shutting off the infusion, increasing the rate, or leaving it as is would not address the elevated aPTT level and may lead to complications.

5. A client with type 1 diabetes mellitus has influenza. The nurse should instruct the client to:

• A. Increase the frequency of self-monitoring (blood glucose testing).
• B. Reduce food intake to alleviate nausea.
• C. Discontinue the insulin dose if unable to eat.
• D. Take the normal dose of insulin.

Correct answer: A

Rationale: During illness, individuals with type 1 diabetes mellitus may experience increased insulin requirements due to factors such as stress and the release of counterregulatory hormones. Increasing the frequency of self-monitoring, as stated in choice A, is crucial to closely monitor and adjust insulin doses as needed. Choice B, reducing food intake to alleviate nausea, is incorrect as it may lead to hypoglycemia and does not address the increased insulin needs during illness. Choice C, discontinuing the insulin dose if unable to eat, is dangerous as it can result in uncontrolled hyperglycemia. Choice D, taking the normal dose of insulin, may not be sufficient during illness when insulin requirements are likely elevated.
