Nursing Elites

1. A client with chronic obstructive pulmonary disease (COPD) who is beginning oxygen therapy asks the nurse why the flow rate cannot be increased to more than 2 L/min. The nurse responds that this would be harmful because it could:

• A. Be drying to nasal passages
• B. Decrease the client’s oxygen-based respiratory drive
• C. Increase the risk of pneumonia due to drier air passages
• D. Decrease the client’s carbon dioxide–based respiratory drive

Correct answer: B

Rationale: Increasing the oxygen flow rate beyond 2 L/min for a client with COPD can decrease the client's oxygen-based respiratory drive. In clients with COPD, the natural respiratory drive is based on the level of oxygen instead of carbon dioxide, as seen in healthy individuals. Increasing the oxygen level independently can suppress the drive to breathe, leading to respiratory failure. Choices A, C, and D are incorrect because drying of nasal passages, increased risk of pneumonia due to drier air passages, and decreasing the carbon dioxide-based respiratory drive are not the primary concerns associated with increasing the oxygen flow rate in a client with COPD.

2. The client with chronic renal failure is receiving hemodialysis. Which of the following laboratory values should the nurse monitor closely?

• A. Hemoglobin level.
• B. Blood urea nitrogen (BUN) level.
• C. Serum potassium level.
• D. Creatinine level.

Correct answer: C

Rationale: The serum potassium level should be monitored closely in clients undergoing hemodialysis due to the risk of hyperkalemia. Hemodialysis is used to remove waste products and excess electrolytes like potassium from the blood. Monitoring potassium levels is crucial because an imbalance can lead to serious cardiac complications, making it the priority value to monitor in this scenario. Monitoring hemoglobin levels (choice A) is important for anemia assessment in chronic renal failure but is not directly related to hemodialysis. Blood urea nitrogen (BUN) levels (choice B) and creatinine levels (choice D) are commonly monitored in renal function tests but are not the top priority for monitoring in a client undergoing hemodialysis.

3. The client with diabetes mellitus is being taught how to prevent or delay chronic kidney disease (CKD). Which client statements indicate a lack of understanding of the teaching? (Select all that apply.)

• A. I can continue to take an aspirin every 4 to 8 hours for my pain.
• B. My weight should be maintained at a body mass index of 30.
• C. Smoking should be stopped as soon as possible.
• D. A & B

Correct answer: D

Rationale: The correct answer is D. Both statements A and B indicate a lack of understanding of CKD prevention. Taking aspirin every 4 to 8 hours can lead to kidney damage, and maintaining a body mass index (BMI) of 30 is considered overweight, which can increase the risk of developing CKD. Statement C, on the other hand, correctly addresses smoking cessation, which is crucial in preventing CKD. Therefore, choices A and B are incorrect as they do not align with CKD prevention strategies, making option D the correct choice.

4. A client is vomiting. For which acid-base imbalance does the nurse assess the client?

• A. Metabolic acidosis
• B. Metabolic alkalosis
• C. Respiratory acidosis
• D. Respiratory alkalosis

Correct answer: B

Rationale: In a client who is vomiting, the loss of gastric fluid containing hydrochloric acid can lead to metabolic alkalosis. Metabolic alkalosis is caused by the loss of acids such as hydrochloric acid from the body. Therefore, in this scenario, the nurse should assess the client for metabolic alkalosis. Choices A, C, and D are incorrect because vomiting does not typically lead to metabolic acidosis, respiratory acidosis, or respiratory alkalosis.

5. Four hours following surgical repair of a compound fracture of the right ulna, the nurse is unable to palpate the client's right radial pulse. Which action should the nurse take first?

• A. Notify the healthcare provider of the finding immediately.
• B. Complete a neurovascular assessment of the right hand.
• C. Elevate the client's right hand on one or two pillows.
• D. Measure the client's blood pressure and apical pulse rate.

Correct answer: B

Rationale: Completing a neurovascular assessment of the right hand is the priority in this situation. This assessment will help determine the circulation, sensation, and movement of the affected limb, ensuring there are no complications like compartment syndrome or impaired perfusion. Notifying the healthcare provider immediately (Choice A) might be necessary but should come after assessing the client's neurovascular status. Elevating the client's right hand (Choice C) can be helpful in some cases but should not precede a neurovascular assessment. Measuring the client's blood pressure and apical pulse rate (Choice D) is important but not the priority when assessing a potential vascular compromise in the limb.
