The nurse is assessing the exhaled tidal volume (EV ) in a mechanically ventilated patient. T What is the rationale for this assessment?
Correct Answer: D
Rationale: The correct answer is D: Determine the patient’s work of breathing. Assessing the exhaled tidal volume (EV) in a mechanically ventilated patient helps determine how much effort the patient is exerting to breathe. By monitoring the EV, the nurse can evaluate the patient's respiratory status and adjust ventilator settings if needed. It is crucial to ensure that the patient is not working too hard to breathe, as this can lead to respiratory distress.
Incorrect answers:
A: Assess for tension pneumothorax - Tension pneumothorax is typically assessed through other means such as physical examination and chest X-ray.
B: Assess the level of positive end-expiratory pressure - The level of positive end-expiratory pressure is usually set based on the patient's condition and not solely based on the exhaled tidal volume.
C: Compare the tidal volume delivered with the tidal volume prescribed - This comparison is important but does not directly relate to assessing the patient's work of breathing.
