A client in an emergency department has a sucking chest wound resulting from a gunshot. The client has a blood pressure of 100/60 mm Hg, a weak pulse rate of 118/min, and a respiratory rate of 40/min. Which of the following actions should the nurse take?
- A. Raise the foot of the bed to a 90° angle
- B. Remove the dressing to inspect the wound
- C. Prepare to insert a central line
- D. Administer oxygen via nasal cannula
Correct Answer: D
Rationale: The correct answer is D: Administer oxygen via nasal cannula. In a client with a sucking chest wound, the priority is to ensure adequate oxygenation due to potential respiratory compromise. Administering oxygen via nasal cannula will help improve oxygenation and support the client's respiratory function. This action takes precedence over other interventions as hypoxia can lead to further deterioration.
A: Raising the foot of the bed to a 90° angle is not indicated in this situation as it does not address the immediate need for oxygenation.
B: Removing the dressing to inspect the wound can worsen the condition by disrupting any seals in place to prevent air from entering the chest cavity.
C: Preparing to insert a central line is not the priority in this situation as the client's respiratory status needs to be stabilized first.
A client with chronic obstructive pulmonary disease (COPD tells the nurse, 'I can feel the congestion in my lungs, and I certainly cough a lot, but I can't seem to bring anything up.' Which of the following actions should the nurse take to help this client with tenacious bronchial secretions?
- A. Maintaining a semi-Fowler's position as often as possible
- B. Administering oxygen via nasal cannula at 2 L/min
- C. Helping the client select a low-salt diet
- D. Encouraging the client to drink 2 to 3 L of water daily
Correct Answer: D
Rationale: The correct answer is D: Encouraging the client to drink 2 to 3 L of water daily. Increased fluid intake helps to thin out bronchial secretions, making them easier to cough up. Step-by-step rationale:
1. Increased water intake promotes hydration, which thins mucus in the airways.
2. Thinner mucus is easier to expectorate, aiding in clearing airway congestion.
3. Adequate hydration also helps to prevent dehydration, which can further thicken secretions.
Summary:
A: Maintaining a semi-Fowler's position may help with breathing comfort but does not directly address the issue of thick secretions.
B: Administering oxygen is important for COPD patients but does not specifically target bronchial secretions.
C: Selecting a low-salt diet is beneficial for managing fluid retention but does not directly address the issue of tenacious bronchial secretions.
