Nursing Elites

1. 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.

2. The patient will begin taking doxycycline to treat an infection. When should the nurse plan to give this medication?

• A. 1 hour before or 2 hours after a meal.
• B. with an antacid to minimize GI irritation.
• C. with food to improve absorption.
• D. with small sips of water.

Correct answer: C

Rationale: Doxycycline is a lipid-soluble tetracycline that is better absorbed when taken with milk products and food. Taking doxycycline with food helps improve its absorption. It should not be taken on an empty stomach, as this can decrease its effectiveness. Antacids can interfere with the absorption of tetracyclines, so they should not be taken together. While it is important to stay hydrated when taking medications, small sips of water are not specifically recommended for doxycycline administration.

3. The nurse is teaching the main principles of hemodialysis to a client with chronic kidney disease. Which statement by the client indicates a need for further teaching by the nurse?

• A. My sodium level changes due to the movement from the blood into the dialysate.
• B. Dialysis works by the movement of wastes from higher to lower concentration.
• C. Extra fluid can be pulled from the blood by osmosis.
• D. The dialysate is similar to blood but without any toxins.

Correct answer: B

Rationale: The correct answer is B because dialysis works by the movement of solutes from an area of higher concentration to an area of lower concentration, which is known as diffusion. The other statements are accurate: A correctly describes the movement of sodium during hemodialysis, C explains the removal of excess fluid by osmosis, and D highlights the purpose of the dialysate in removing toxins from the blood.

4. A client with overflow incontinence needs assistance with elimination. What intervention should the nurse include in the plan of care?

• A. Stroke the medial aspect of the thigh.
• B. Use intermittent catheterization.
• C. Provide digital anal stimulation.
• D. Use the Valsalva maneuver.

Correct answer: D

Rationale: In clients with overflow incontinence, the voiding reflex arc is impaired. The Valsalva maneuver, which involves holding the breath and bearing down as if to defecate, can help initiate voiding by applying mechanical pressure. Options A and C (stroking the thigh or anal stimulation) rely on an intact reflex arc to trigger elimination and are not effective for clients with overflow incontinence. Intermittent catheterization (Option B) is a last resort due to the high risk of infection and should only be considered if other interventions fail.

5. A client with cirrhosis develops increasing pedal edema and ascites. What dietary modification is most important for the nurse to teach this client?

• A. Avoid high carbohydrate foods.
• B. Decrease intake of fat-soluble vitamins.
• C. Decrease caloric intake.
• D. Restrict salt and fluid intake.

Correct answer: D

Rationale: The correct answer is to restrict salt and fluid intake. In clients with cirrhosis presenting with pedal edema and ascites, excessive fluid retention occurs, necessitating the restriction of salt and fluid to alleviate these symptoms. Choice A, avoiding high carbohydrate foods, is not the priority in this situation. Decreasing intake of fat-soluble vitamins (Choice B) is not specifically indicated for managing edema and ascites in cirrhosis. While maintaining an appropriate caloric intake is important, decreasing caloric intake (Choice C) is not the primary focus when addressing fluid retention in cirrhosis.
