A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 68 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?
Decrease expiratory flow time.
Decrease expiratory pressure.
Increase rate of ventilation.
Increase ventilator tidal volume.
The Correct Answer is B
Choice A rationale:
Decreasing expiratory flow time is not the appropriate intervention in this case. The client's pH and PaCO2 levels suggest respiratory acidosis, which indicates inadequate ventilation. Increasing expiratory flow time might exacerbate the acidosis by reducing ventilation.
Choice C rationale:
Increasing the rate of ventilation (respiratory rate) is a potential intervention to improve the client's acid-base balance. However, it should be done cautiously and under medical supervision to avoid respiratory alkalosis. It is not the first-line intervention in this scenario.
Choice D rationale:
Increasing the ventilator tidal volume may help improve ventilation, but it should also be done under medical guidance to prevent barotrauma. It is not the initial intervention to address the client's respiratory acidosis.

Correct Answer is C
Explanation
Choice A rationale:
The neurology unit supervisor is not the most appropriate nurse to coordinate the progression of care for a client with a spinal cord injury (SCI). While they may have expertise in neurology, the nurse case manager is specifically trained to coordinate and manage the care of patients with complex conditions, including SCI. They can facilitate communication between various healthcare providers and ensure that the client receives comprehensive care throughout their stay.
Choice B rationale:
An adult nurse practitioner may have specialized knowledge in the care of adults, but they may not have the specific skills and training required to coordinate the care of a client with a spinal cord injury in the ICU. Nurse case managers are better equipped to manage complex cases and ensure the continuity of care for the client.
Choice D rationale:
A risk management nurse focuses on minimizing healthcare-related risks and ensuring the safety of patients and staff. While their role is essential, it is not the primary responsibility to coordinate the progression of care for a client with a spinal cord injury. The nurse case manager is better suited for this role as they specialize in care coordination.
