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 D
Explanation
Choice A rationale:
Monitoring blood pressure is a general health assessment measure and may not directly contribute to pain relief in a client with migraine headaches. While it's essential to manage blood pressure as part of overall health, this choice does not address the client's specific request for pain relief.
Choice B rationale:
Taking a few days off work may provide some relief from external stressors, but it is not a reliable intervention for migraine pain relief. Migraine management typically involves strategies that directly target headache symptoms.
Choice C rationale:
Learning muscle relaxation techniques can be helpful in managing migraine headaches. Relaxation techniques, such as progressive muscle relaxation, can reduce muscle tension and help alleviate headache symptoms. However, it may not be the highest-priority intervention.
Choice D rationale:
Lying down in a dark, quiet room is the most appropriate intervention for obtaining pain relief from a migraine headache. This approach minimizes sensory stimuli, reduces external factors that may exacerbate the headache, and promotes relaxation. It is a well-established non-pharmaceutical method for managing migraine pain.
Correct Answer is ["C","E"]
Explanation
Choice A rationale:
A bedside commode is positioned near the bed. Positioning a bedside commode near the bed is appropriate for a client with heart failure and COPD who may have mobility issues or difficulty walking to the bathroom. It promotes safety and convenience for the client.
Choice B rationale:
A full pitcher of water is on the bedside table. While it's essential to keep clients with heart failure adequately hydrated, having a full pitcher of water within easy reach might encourage excessive fluid intake, which can exacerbate heart failure symptoms. However, this choice is not an immediate risk requiring intervention.
Choice C rationale:
The client is lying in a supine position in bed. A client with heart failure and COPD should not be lying in a supine position because it can exacerbate respiratory distress and increase the workload of the heart. This is an observation that requires immediate intervention, such as repositioning the client to an upright or semi-fowler's position.
Choice D rationale:
A saline lock is present in the right forearm. The presence of a saline lock is a standard precaution in a hospitalized client and does not require immediate intervention unless there are specific issues with it, such as signs of infection or dislodgement. It does not pose an immediate harm to the client.
Choice E rationale:
A low sodium diet tray was brought to the room. A low sodium diet is crucial for managing heart failure because excessive sodium intake can lead to fluid retention and exacerbate symptoms. Ensuring that the client follows the prescribed diet is essential for their well-being, and any deviations may require immediate intervention.
