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:
Avocados and cheese are not specifically recommended for a client with a postoperative wound infection. While a balanced diet is important for overall health, yogurt or buttermilk is a better choice due to their probiotic content, which may promote gut health and support the immune system.
Choice B rationale:
Fresh fruits are generally a healthy dietary choice, but they are not particularly relevant to the management of a postoperative wound infection. The emphasis for this client should be on foods that support wound healing and immune function, such as yogurt or buttermilk.
Choice D rationale:
Green leafy vegetables are rich in vitamins and minerals, but they are not a primary focus for a client with a postoperative wound infection. Again, the emphasis should be on foods that support the immune system and overall recovery, such as yogurt or buttermilk.
Correct Answer is B
Explanation
Choice A rationale:
Substituting natural fruit juices for carbonated drinks may be a beneficial dietary change, but it does not address the client's immediate issue of severe pain and inability to bear weight on the right ankle. This choice does not directly address the client's current problem and should not be the priority instruction in discharge teaching.
Choice B rationale:
Encouraging active range of motion to limit stiffness is the most appropriate instruction in this situation. The client's inability to bear weight on the right ankle after making dietary changes may be related to musculoskeletal issues or gouty arthritis. Active range of motion exercises can help prevent stiffness and improve joint function.
Choice C rationale:
Using an electric heating pad when pain is at its worst may provide some comfort, but it does not address the underlying cause of the severe pain in the right ankle. It is important to address the cause of the pain rather than relying solely on symptom management.
Choice D rationale:
Avoiding the consumption of wine, beer, and coffee may be relevant for some medical conditions, but it does not directly address the client's current problem of severe ankle pain and inability to bear weight. It is not the most immediate concern.
