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 C
The correct answer is choice C: Increase rate of ventilation.
Choice A rationale:
Decreasing expiratory flow time would not directly address the elevated PaCO2 levels. This intervention is more related to managing expiratory phase issues rather than correcting respiratory acidosis.
Choice B rationale:
Decreasing expiratory pressure might help with certain ventilation issues, but it does not specifically target the elevated PaCO2 and resulting acidosis.
Choice C rationale:
Increasing the rate of ventilation helps to blow off more CO2, thereby reducing PaCO2 levels and correcting the respiratory acidosis indicated by the pH of 7.26 and PaCO2 of 68 mm Hg.
Choice D rationale:
Increasing the ventilator tidal volume could also help reduce PaCO2 by increasing the amount of air exchanged with each breath. However, increasing the rate of ventilation is generally a more immediate and effective intervention for acute respiratory acidosis.

Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A rationale:
Provide a safe and calm environment for the client during a panic attack. Creating a safe and calm environment is crucial during a panic attack. It can help the client feel more secure and reduce the intensity and duration of the panic attack.
Choice B rationale:
Use therapeutic communication skills to establish rapport and trust with the client. Therapeutic communication is essential for clients with panic disorder. It helps establish a trusting relationship between the nurse and the client, which is crucial for effective treatment and support.
Choice C rationale:
Educate the client about panic disorder and its treatment options. Educating the client about their condition and available treatment options empowers them to make informed decisions about their care. It also reduces anxiety and fear associated with the disorder.
Choice D rationale:
Encourage the client to participate in cognitive-behavioral therapy (CBT). Cognitive-behavioral therapy is a well-established and effective treatment for panic disorder. Encouraging the client to participate in CBT can help them develop coping strategies and manage their symptoms.
Choice E rationale:
Refer the client to self-help groups for peer support and education. Self-help groups can provide valuable peer support and education to individuals with panic disorder. Being part of such a group can reduce feelings of isolation and provide practical advice for managing the condition.
Correct Answer is D
Explanation
Choice A rationale:
The client being the oldest of their siblings is not a contributing factor related to the development of conduct disorder. Family dynamics such as birth order may have some influence on personality traits, but they are not a primary factor in the development of conduct disorder.
Choice B rationale:
The fact that the client's father lives in the client's home is a family dynamic, but it does not necessarily contribute to the development of conduct disorder. Other factors related to parenting style, communication, and family interactions play a more significant role in the development of conduct disorder.
Choice C rationale:
The client's mother having asthma is a medical condition and not a family dynamic that directly contributes to the development of conduct disorder. Conduct disorder is more closely associated with social, environmental, and psychological factors.
Choice D rationale:
The presence of several siblings in the family dynamic can contribute to the development of conduct disorder. Increased family size can lead to competition for attention and resources, which may affect the child's behavior and interactions. Sibling relationships and family dynamics are crucial in shaping a child's behavior and psychological well-being.
