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. During a severe asthma exacerbation in a client, what is the nurse's priority?

• A. Administer a rescue inhaler immediately
• B. Prepare for intubation
• C. Encourage deep breathing exercises
• D. Monitor oxygen saturation levels

Correct answer: A

Rationale: During a severe asthma exacerbation, the nurse's priority is to administer a rescue inhaler immediately. This action helps open the airways and improve breathing, which is crucial in managing the exacerbation. Choice B, preparing for intubation, would be considered if the client's condition deteriorates and they are unable to maintain adequate oxygenation even after using the rescue inhaler. Encouraging deep breathing exercises (Choice C) may not be appropriate during a severe exacerbation as the client may struggle to breathe. While monitoring oxygen saturation levels (Choice D) is important, the immediate administration of a rescue inhaler takes precedence to address the acute breathing difficulty.

3. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.

4. The client with chronic kidney disease (CKD) is being educated about dietary modifications. Which dietary restriction should the nurse emphasize the most?

• A. Limit intake of high-fiber foods
• B. Restrict protein intake
• C. Avoid dairy products
• D. Increase fluid intake

Correct answer: B

Rationale: The most crucial dietary restriction to emphasize for a client with chronic kidney disease (CKD) is to restrict protein intake. By restricting protein intake, the workload on the kidneys is reduced, which helps slow the progression of CKD. While high-fiber foods are generally beneficial, they may need to be limited in some individuals with CKD due to potassium concerns, making choice A less critical. Avoiding dairy products may be necessary in some cases to control phosphorus levels, but it is not as vital as restricting protein intake. Increasing fluid intake is essential for kidney health, but it is not the most critical dietary modification for clients with CKD.

5. After placement of a left subclavian central venous catheter (CVC), the nurse receives a report of the X-ray findings indicating that the CVC tip is in the client's superior vena cava. Which action should the nurse implement?

• A. Remove the catheter and apply direct pressure for 5 minutes.
• B. Initiate intravenous fluids as prescribed.
• C. Secure the catheter using aseptic technique.
• D. Notify the healthcare provider of the need to reposition the catheter.

Correct answer: B

Rationale: Initiating intravenous fluids as prescribed is the appropriate action when the CVC tip is correctly placed in the superior vena cava. Intravenous fluids can now be administered effectively through the central line. Removing the catheter and applying direct pressure is unnecessary and not indicated as the tip is in the correct position. Securing the catheter using aseptic technique is important for preventing infections but is not the immediate action needed in this situation. Notifying the healthcare provider of the need to reposition the catheter may delay necessary fluid administration, which is the priority at this time.
