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 correct answer is D: Development of subcutaneous emphysema. This finding indicates air leakage, which can lead to potential complications like tension pneumothorax. Subcutaneous emphysema is a serious concern that requires immediate intervention.
A: Chest tube eyelets not visible - This is not a concerning finding as long as the chest tube is properly secured and functioning.
B: Continuous bubbling in the suction control chamber - This can indicate proper functioning of the system.
C: Presence of tidal fluctuation in the water seal chamber - This indicates that the system is working correctly, with the water seal chamber fluctuating with the patient's breathing.
Exercise can improve circulation and cardiovascular fitness by decreasing
- A. The number of small blood vessels throughout the body
- B. The heart rate and blood pressure
- C. High-density lipoproteins (HDL) in the blood
- D. The body’s breathing capacity
Correct Answer: B
Rationale: The correct answer is B because exercise can improve circulation and cardiovascular fitness by reducing the heart rate and blood pressure. When we exercise, our heart becomes more efficient at pumping blood, leading to a lower resting heart rate and reduced blood pressure. This helps improve circulation and strengthens the cardiovascular system.
Explanation for why the other choices are incorrect:
A: The number of small blood vessels throughout the body - Exercise actually promotes the growth of new blood vessels, improving circulation.
C: High-density lipoproteins (HDL) in the blood - Exercise can increase HDL levels, which is beneficial for heart health.
D: The body’s breathing capacity - Exercise can improve lung function and increase breathing capacity, but it is not directly related to circulation or cardiovascular fitness.
