- A. multiple sclerosis.
- B. human immunodeficiency virus (HIV).
- C. Parkinson's disease.
- D. Guillain-Barré syndrome.

After a thoracotomy, the nurse instructs the client to perform deep-breathing exercises. Which of the following is an expected outcome of these exercises?
- A. Deep breathing elevates the diaphragm, which enlarges the thorax and increases the lung surface available for gas exchange.
- B. Deep breathing increases blood flow to the lungs to allow them to recover from the trauma of surgery.
- C. Deep breathing controls the rate of air flow to the remaining lobe so that it will not become hyperinflated.
- D. Deep breathing expands the alveoli and increases the lung surface available for ventilation.
Correct Answer: D
Rationale: Deep breathing expands alveoli, increasing lung surface for ventilation and preventing atelectasis post-thoracotomy. It does not elevate the diaphragm, increase blood flow, or control airflow to prevent hyperinflation.
The nurse is assessing a client with hepatitis and notices that the AST and ALT levels have increased. Which of the following statements by the client requires further instruction by the nurse?
- A. I require increased periods of rest.
- B. I follow a low-fat, high carbohydrate diet.
- C. I eat dry toast to relieve my nausea.
- D. I take acetaminophen (Tylenol) for arthritis pain.

The nurse should instruct the client with an ileostomy to report which of the following signs and symptoms immediately?
- A. Passage of liquid stool from the stoma.
- B. Occasional presence of undigested food in the effluent.
- C. Absence of drainage from the ileostomy for 6 or more hours.
- D. Temperature of 99.8°F (37.7°C).
Correct Answer: C
Rationale: Absence of drainage from an ileostomy for 6 or more hours may indicate a blockage, requiring immediate reporting. Liquid stool and undigested food are normal, and a slightly elevated temperature is less urgent unless persistent. CN: Physiological adaptation; CL: Synthesize
In order to prevent recurrent vasospastic episodes with Raynaud's phenomenon, the nurse should instruct the client to:
- A. Keep the hands and feet elevated as much as possible
- B. Use a vibrating massage device on the hands
- C. Wear gloves when obtaining food from the refrigerator
- D. Increase coffee intake to 2 cups per day
Correct Answer: C
Rationale: Wearing gloves when obtaining food from the refrigerator prevents cold-triggered vasospasm in Raynaud's. Elevation is irrelevant, vibrating devices may worsen symptoms, and coffee (caffeine) can cause vasoconstriction, increasing episodes.
