Nursing Elites

1. A client's arterial blood gas results show a pH of 7.3 and a PaCO2 of 50 mm Hg. The client is experiencing which of the following acid-base imbalances?

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

Correct answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

2. While providing teaching to a client who is postoperative following coronary artery bypass graft (CABG) surgery and is receiving opioid medications to manage discomfort, which of the following desired effects of medications should the nurse identify as most important for the client's recovery?

• A. It decreases the client's level of anxiety.
• B. It facilitates the client's deep breathing.
• C. It enhances the client's ability to sleep.
• D. It reduces the client's blood pressure.

Correct answer: B

Rationale: In the postoperative period following CABG surgery, deep breathing exercises are essential to prevent complications such as atelectasis and pneumonia. Opioid medications can depress the respiratory system, making it crucial for the nurse to emphasize the importance of deep breathing to maintain optimal lung function. While managing pain and anxiety are important, facilitating deep breathing takes precedence in this situation to promote effective recovery and prevent respiratory complications.

3. A client is prescribed prednisone for asthma management. Which statement by the client indicates a need for further teaching?

• A. I will take this medication every day to prevent asthma attacks.
• B. I will avoid people with infections while taking this medication.
• C. I will take this medication with food to prevent stomach upset.
• D. I will stop taking this medication if I feel fine.

Correct answer: D

Rationale: The correct answer is D because prednisone, a corticosteroid, should not be abruptly stopped. It must be tapered off gradually to prevent adrenal insufficiency. Choices A, B, and C demonstrate proper understanding of the medication's use and side effects, emphasizing the importance of daily intake, infection prevention, and taking it with food to avoid stomach upset.

4. A client is scheduled for a colonoscopy and receiving education from a healthcare provider. Which statement by the client indicates a need for further teaching?

• A. I can have clear liquids up to 2 hours before the procedure.
• B. I need to take a laxative the night before the procedure.
• C. I will be sedated during the procedure.
• D. I should avoid eating solid foods for 24 hours before the procedure.

Correct answer: D

Rationale: The correct answer is D because clients are typically instructed to avoid solid foods for 12-24 hours before a colonoscopy, not a full 24 hours. This statement indicates a need for further teaching to ensure the client follows the correct dietary instructions for the procedure.

5. A client learns about pursed-lip breathing. Which statement by the client indicates teaching has been effective?

• A. I will breathe in quickly through my mouth and out through my nose.
• B. I will breathe in slowly through my nose and out through pursed lips.
• C. I will hold my breath for 10 seconds before exhaling.
• D. I will breathe in and out through pursed lips.

Correct answer: B

Rationale: The correct technique for pursed-lip breathing involves inhaling slowly through the nose and exhaling slowly through pursed lips. This technique helps improve expiration and reduce air trapping. Breathing in quickly, holding the breath, or breathing in and out through pursed lips does not align with the correct method of pursed-lip breathing.
