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. While assisting a client with a closed chest tube drainage system to move from bed to a chair, the chest tube gets caught on the chair leg and becomes dislodged from the insertion site. What is the immediate priority for the nurse?

• A. Contacting the physician
• B. Reinserting the chest tube
• C. Transferring the client back to bed
• D. Covering the insertion site with a sterile occlusive dressing

Correct answer: D

Rationale: The immediate priority for the nurse when a chest tube becomes dislodged from the insertion site is to cover the site with a sterile occlusive dressing. This action helps prevent air from entering the pleural space, which could lead to a pneumothorax. The nurse should then perform a respiratory assessment to monitor the client's breathing, assist the client back into bed to a position of comfort, and notify the physician. Reinserting the chest tube is a task for the physician, not the nurse, as it requires specific training and expertise.

3. What is the priority assessment for a patient receiving intravenous morphine?

• A. Assessing the patient's blood pressure.
• B. Monitoring the patient's respiratory rate.
• C. Checking the patient's pain level.
• D. Monitoring the patient's oxygen saturation.

Correct answer: B

Rationale: The correct answer is monitoring the patient's respiratory rate. When a patient receives intravenous morphine, the priority assessment is to monitor the respiratory rate due to the risk of respiratory depression associated with morphine. This assessment helps in detecting and managing any potential respiratory complications promptly. Assessing blood pressure, checking pain level, and monitoring oxygen saturation are important aspects of patient care but are not the priority when considering the specific risk of respiratory depression with intravenous morphine.

4. A client arrived to the medical-surgical unit 4 hours after a transurethral resection of the prostate (TURP). A triple-lumen catheter for continuous bladder irrigation with normal saline is infusing, and the nurse observes dark, pink-tinged outflow with blood clots in the tubing and collection bag. Which action should the nurse take?

• A. Monitoring catheter drainage
• B. Decreasing the flow rate
• C. Irrigating the catheter manually
• D. Discontinuing infusing the solution

Correct answer: C

Rationale: In this scenario, the nurse should choose option C - irrigating the catheter manually. This action can help clear the clots from the catheter and ensure proper bladder drainage. Monitoring catheter drainage (option A) alone may not address the issue of clots obstructing the flow. Decreasing the flow rate (option B) could potentially worsen clot formation. Discontinuing the infusing solution (option D) without addressing the clots first may lead to inadequate irrigation and increase the risk of complications.

5. In a patient with type 1 diabetes, which of the following is a sign of diabetic ketoacidosis (DKA)?

• A. Polyuria
• B. Bradycardia
• C. Dry skin
• D. Tachycardia

Correct answer: D

Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.
