1. A student learns about modifiable risk factors for coronary artery disease. Which factors does this include? (Select one that does not apply)

• A. Age
• B. Hypertension
• C. Obesity
• D. Smoking

Correct answer: A

Rationale: Hypertension, obesity, smoking, and excessive stress are all modifiable risk factors for coronary artery disease, as they can be changed or controlled through interventions. Age, on the other hand, is a nonmodifiable risk factor, meaning it cannot be altered. Understanding the difference between modifiable and nonmodifiable risk factors is essential in preventive healthcare strategies.

2. 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.

3. A healthcare professional is assessing a client who has a fracture of the femur. Vital signs are obtained on admission and again in 2 hours. Which of the following changes in assessment should indicate to the healthcare professional that the client could be developing a serious complication?

• A. Increased respiratory rate from 18 to 44/min
• B. Increased oral temperature from 36.6° C (97.8° F) to 37° C (98.6° F)
• C. Increased blood pressure from 112/68 to 120/72 mm Hg
• D. Increased heart rate from 68 to 72/min

Correct answer: A

Rationale: An increased respiratory rate from 18 to 44/min is a significant change that should alert the healthcare professional to a potential serious complication. Such a drastic increase in respiratory rate may indicate respiratory distress or hypoxia, which are critical conditions requiring immediate attention. The other options show minor changes in vital signs that are within normal limits and are less likely to indicate a serious complication.

4. A client is 1 day postoperative following a lobectomy with a chest tube drainage system in place. Which finding by the nurse indicates a need for intervention?

• A. Chest tube eyelets not visible
• B. Continuous bubbling in the suction control chamber
• C. Presence of tidal fluctuation in the water seal chamber
• D. Development of subcutaneous emphysema

Correct answer: D

Rationale: The development of subcutaneous emphysema is a concerning finding that requires immediate intervention. Subcutaneous emphysema results from air leaking into the tissues, which can lead to respiratory compromise. It is important to address this issue promptly to prevent further complications. The other options are normal or expected findings in a chest tube drainage system. Chest tube eyelets not being visible may indicate dislodgement, continuous bubbling in the suction control chamber indicates proper functioning, and the presence of tidal fluctuation in the water seal chamber demonstrates appropriate drainage and lung re-expansion.

5. A client has a chest tube in place connected to a closed chest drainage system. Which of the following findings should indicate to the nurse that the client's lung has re-expanded?

• A. Oxygen saturation of 95%
• B. No fluctuations in the water seal chamber
• C. No reports of pleuritic chest pain
• D. Occasional bubbling in the water-seal chamber

Correct answer: B

Rationale: The absence of fluctuations in the water seal chamber indicates that the client's lung has re-expanded. This finding suggests that the negative pressure in the pleural space is restored, preventing air from entering the system. Oxygen saturation, absence of pleuritic chest pain, and occasional bubbling in the water-seal chamber are important assessments but do not specifically indicate lung re-expansion.
