Nursing Elites

1. 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.

2. 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.

3. The nurse is teaching a client with hypertension about lifestyle modifications. Which recommendation is most effective for lowering blood pressure?

• A. Increase intake of red meat
• B. Engage in regular physical activity
• C. Consume a high-sodium diet
• D. Limit fluid intake to 1 liter per day

Correct answer: B

Rationale: Engaging in regular physical activity is a highly effective recommendation for lowering blood pressure and improving overall cardiovascular health. Regular exercise helps to strengthen the heart, improve blood circulation, and manage weight, all of which contribute to reducing blood pressure levels. Choices A, C, and D are incorrect. Increasing intake of red meat can lead to higher saturated fat consumption, which is detrimental to heart health. Consuming a high-sodium diet can exacerbate hypertension by increasing blood pressure. Limiting fluid intake to 1 liter per day may lead to dehydration and is not a recommended approach for managing hypertension.

4. A client is admitted with a diagnosis of pneumonia. Which intervention should the nurse implement to promote airway clearance?

• A. Administer bronchodilators as prescribed.
• B. Encourage increased fluid intake.
• C. Perform chest physiotherapy.
• D. Provide humidified oxygen.

Correct answer: B

Rationale: Encouraging increased fluid intake is the most appropriate intervention to promote airway clearance in a client with pneumonia. Adequate hydration helps to thin respiratory secretions, making it easier for the client to cough up and clear the airways. Administering bronchodilators (Choice A) may help with bronchospasm but does not directly promote airway clearance. Chest physiotherapy (Choice C) can be beneficial in certain cases but may not be the initial intervention for promoting airway clearance. Providing humidified oxygen (Choice D) can help improve oxygenation but does not specifically target airway clearance in pneumonia.

5. A client with type 1 diabetes is experiencing symptoms of hypoglycemia. What is the nurse's priority intervention?

• A. Administer glucagon intramuscularly
• B. Provide a complex carbohydrate snack
• C. Administer 50% dextrose intravenously
• D. Give 15 grams of a fast-acting carbohydrate

Correct answer: D

Rationale: The priority intervention for a client with type 1 diabetes experiencing symptoms of hypoglycemia is to give 15 grams of a fast-acting carbohydrate. In a hypoglycemic state, the priority is to quickly raise the blood glucose level. Administering glucagon intramuscularly (Choice A) is reserved for severe hypoglycemia when the client is unable to take oral carbohydrates. Providing a complex carbohydrate snack (Choice B) is beneficial after the initial treatment of hypoglycemia to prevent recurrence. Administering 50% dextrose intravenously (Choice C) is a more invasive intervention typically done in a hospital setting for severe cases.
