1. When caring for a client with acute renal failure, which laboratory value is most important to monitor?

• A. Serum sodium
• B. Serum potassium
• C. Serum calcium
• D. Serum chloride

Correct answer: B

Rationale: In acute renal failure, monitoring serum potassium is crucial because impaired kidney function can lead to hyperkalemia, which can result in life-threatening cardiac dysrhythmias. Elevated potassium levels need close monitoring and prompt interventions to prevent serious complications.

2. What instruction should be included when teaching a client with asthma about using a metered-dose inhaler (MDI)?

• A. Shake the inhaler well before use.
• B. Inhale rapidly while administering the medication.
• C. Administer the medication while lying down.
• D. Hold the inhaler 2 inches away from the mouth while inhaling.

Correct answer: A

Rationale: Shaking the inhaler well before use ensures that the medication is properly mixed, allowing for an accurate dose with each administration. Inhaling slowly and deeply, not rapidly, helps the medication reach the lungs effectively. The medication should be administered while sitting or standing to facilitate proper lung expansion and airflow. Holding the inhaler 2 inches away from the mouth can lead to medication loss; it should be placed directly in the mouth or used with a spacer to optimize delivery to the airways.

3. A healthcare professional is assessing a client who has postoperative atelectasis and is hypoxic. Which of the following manifestations should the healthcare professional expect?

• A. Bradycardia
• B. Bradypnea
• C. Lethargy
• D. Intercostal retractions

Correct answer: D

Rationale: Postoperative atelectasis can lead to hypoxia, which causes respiratory distress. Intercostal retractions, where the muscles between the ribs pull inward during inspiration, are a common sign of respiratory distress in a client with atelectasis. Bradycardia (slow heart rate), Bradypnea (slow breathing rate), and lethargy are not typically associated with atelectasis and hypoxia.

4. The healthcare provider is caring for a postoperative client who has a chest tube connected to suction and a water seal drainage system. Which of the following indicates to the healthcare provider that the chest tube is functioning properly?

• A. Fluctuation of the fluid level within the water seal chamber
• B. Absence of fluid in the drainage tubing
• C. Continuous bubbling within the water seal chamber
• D. Equal amounts of fluid drainage in each collection chamber

Correct answer: A

Rationale: Fluctuation of the fluid level within the water seal chamber indicates proper functioning of the chest tube. This fluctuation reflects the normal ebb and flow of air and fluid in the pleural space, demonstrating that the system is maintaining the appropriate pressure. Continuous bubbling in the water seal chamber may indicate an air leak, absence of fluid in the drainage tubing suggests a blockage, and equal amounts of fluid drainage in each collection chamber are not expected in this system.

5. A healthcare professional assesses a client who is experiencing an acute asthma attack. Which assessment finding requires immediate intervention?

• A. Loud wheezing
• B. Increased respiratory rate
• C. Use of accessory muscles
• D. Silent chest

Correct answer: D

Rationale: A silent chest in a client experiencing an acute asthma attack indicates severe airway obstruction and impending respiratory failure. It is a critical finding that requires immediate intervention as it signifies a lack of airflow and ventilation. Loud wheezing, increased respiratory rate, and use of accessory muscles are common signs of an asthma attack and indicate the body's attempt to compensate. However, a silent chest suggests a dangerous lack of airflow that necessitates urgent medical attention to prevent respiratory arrest.
