Nursing Elites

1. What are the final factors that contribute to blood pressure? (Select all that apply)

• A. Heart rate
• B. Stroke volume
• C. Peripheral resistance
• D. Neuroendocrine hormones

Correct answer: D

Rationale: Neuroendocrine hormones play a crucial role in regulating blood pressure by influencing factors like fluid balance, blood volume, and vessel constriction. While heart rate, stroke volume, and peripheral resistance are important factors affecting blood pressure, the final parameters that directly produce blood pressure are influenced by neuroendocrine hormones. Therefore, choice D is the correct answer. Choices A, B, and C are involved in the regulation of blood pressure but are not the final parameters that directly produce it.

2. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

3. The client has chronic renal failure. What dietary modification is most important for this client?

• A. Increase protein intake
• B. Limit potassium-rich foods
• C. Increase sodium intake
• D. Encourage dairy products

Correct answer: B

Rationale: Limiting potassium-rich foods is crucial in chronic renal failure to prevent hyperkalemia, which can lead to cardiac complications. Excessive protein intake can increase the workload on the kidneys and may result in the accumulation of uremic toxins. Increasing sodium intake is generally discouraged in chronic renal failure due to its association with hypertension and fluid retention. Encouraging dairy products may not be suitable for all clients with chronic renal failure, as they are a significant source of phosphorus, which needs to be limited in renal failure to prevent mineral imbalances.

4. While caring for a client's postoperative dressing, the nurse observes purulent wound drainage. Previously, the wound was inflamed and tender but without drainage. Which is the most important action for the nurse to take?

• A. Determine if the drainage has an unpleasant odor.
• B. Monitor the client's white blood cell count (WBC).
• C. Request a culture and sensitivity of the wound.
• D. Cleanse the wound with a sterile saline solution.

Correct answer: C

Rationale: Requesting a culture and sensitivity of the wound is the most crucial action in this scenario. This will help identify the specific organism causing the infection and determine its sensitivity to antibiotics, guiding appropriate antibiotic therapy. Option A is less critical as odor alone may not provide enough information about the type of infection. Monitoring the client's white blood cell count (WBC) in option B is important but not as immediate as obtaining a wound culture. Cleansing the wound with a sterile saline solution in option D is necessary but should follow after obtaining the culture results to ensure proper treatment.

5. The nurse is planning to ambulate a client who has been on bed rest for 24 hours following a Colon Resection. To ambulate this client safely, which intervention should the nurse implement first?

• A. Place non-skid shoes on the client
• B. Show the client how to use the call light
• C. Use a gait belt to support the client
• D. Assist the client to a bedside sitting position

Correct answer: D

Rationale: To ambulate a client safely after a period of bed rest, the nurse should first assist the client to a bedside sitting position. This initial step ensures the client is stable before attempting to stand and walk, reducing the risk of falls and allowing for a gradual adjustment to activity post-bed rest. Placing non-skid shoes, showing how to use the call light, or using a gait belt are important but should come after ensuring the client is safely seated and stable.
