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 B
Explanation
Choice A rationale:
Leaving the client alone to give them space is not an appropriate intervention for a client with depression and a history of suicide attempts. Isolation can increase feelings of hopelessness and despair, potentially leading to self-harm or suicidal thoughts.
Choice B rationale:
Removing any potential means of self-harm from the client's environment is the most essential intervention in this scenario. It is crucial to ensure the client's safety by eliminating access to items or substances that could be used for self-harm, such as medications, sharp objects, or other dangerous items. This intervention helps reduce the immediate risk of harm.
Choice C rationale:
Encouraging the client to confront their feelings of hopelessness is important in the long term, as it can be part of therapeutic interventions. However, it should not be the immediate priority when the client is at risk of self-harm. Ensuring their safety is paramount.
Choice D rationale:
Telling the client that they should be grateful for what they have is not an appropriate intervention. It can be perceived as dismissive of their feelings and may worsen their sense of hopelessness and isolation.
Correct Answer is B
Explanation
Choice A rationale:
Assessment of tobacco use geared toward adolescents. Rationale: While assessing tobacco use is essential for promoting health in adolescents, the question is about developing a class about mental health and addressing the increase in suicides in the community. Assessing tobacco use is not directly related to this topic. Stress self-management techniques are more relevant.
Choice B rationale:
Exploration of stress self-management techniques. Rationale: This is the correct answer. Addressing stress and teaching adolescents self-management techniques is crucial in the context of mental health promotion and suicide prevention. Adolescents often face stressors, and providing them with effective strategies to manage stress can contribute to their overall well-being.
Choice C rationale:
Video with statistics showing trends in suicide rates. Rationale: While providing statistics about suicide rates can be informative, it may not be the most engaging or effective method for teaching adolescents about mental health and stress management. Interactive activities and skill-building exercises are often more beneficial.
Choice D rationale:
Handouts for local substance abuse treatment centers. Rationale: Providing handouts for substance abuse treatment centers
