Nursing Elites

1. The nurse is assessing a client with chronic kidney disease (CKD) who is receiving erythropoietin therapy. Which laboratory value should be closely monitored?

• A. Serum potassium level
• B. Hemoglobin level
• C. White blood cell count
• D. Serum sodium level of 135 mEq/L

Correct answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

2. A client is receiving a full-strength continuous enteral tube feeding at 50 ml/hour and has developed diarrhea. The client has a new prescription to change the feeding to half strength. What intervention should the nurse implement?

• A. Add equal amounts of water and feeding to a feeding bag and infuse at 50 ml/hour
• B. Continue the full-strength feeding after decreasing the rate of infusion to 25 ml/hour
• C. Maintain the present feeding until diarrhea subsides and then begin the new prescription
• D. Withhold any further feeding until clarifying the prescription with the healthcare provider

Correct answer: A

Rationale: The correct intervention is to dilute the formula by adding equal amounts of water and feeding to a feeding bag and infusing it at 50 ml/hour. This can help alleviate the diarrhea that has developed. Diarrhea can occur as a complication of enteral tube feeding and can be due to a variety of causes, including hyperosmolar formula. Choice B is incorrect as continuing the full-strength feeding, even at a lower rate, may not address the issue of diarrhea. Choice C is incorrect because it is important to follow the new prescription to manage the diarrhea effectively. Choice D is incorrect as withholding feeding without taking appropriate action may delay necessary intervention.

3. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding requires immediate intervention?

• A. Barrel-shaped chest
• B. Use of accessory muscles
• C. Oxygen saturation of 85%
• D. Inspiratory crackles

Correct answer: C

Rationale: An oxygen saturation of 85% is significantly low for a client with COPD and requires immediate intervention to prevent hypoxemia. Oxygen saturation below 90% indicates poor oxygenation and poses a risk of tissue hypoxia, making it a critical finding that needs prompt attention. Barrel-shaped chest and inspiratory crackles are commonly seen in clients with COPD and do not necessitate immediate intervention. The use of accessory muscles may indicate increased work of breathing but does not pose the same level of immediate threat as severe hypoxemia.

4. The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

• A. Initiation of the impulses from a location outside the SA node
• B. Inability of the SA node to initiate an impulse at the normal rate
• C. Increased conduction time from the SA node to the AV junction
• D. Interference with the conduction through one or both ventricles

Correct answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

5. A client with chronic obstructive pulmonary disease (COPD) is admitted with an exacerbation. Which assessment finding is most concerning?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 24 breaths per minute
• C. Use of accessory muscles
• D. Inspiratory crackles

Correct answer: C

Rationale: The correct answer is C. Use of accessory muscles is the most concerning finding in a client with COPD experiencing an exacerbation. This indicates increased work of breathing and can be a sign of respiratory failure, requiring immediate intervention. Oxygen saturation of 90% is low but not as concerning as the increased work of breathing. A respiratory rate of 24 breaths per minute can be within normal limits. Inspiratory crackles may be present in COPD due to airway inflammation but are not as concerning as the use of accessory muscles.
