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 D
Explanation
An 18-year-old client with a mild mental disability is a client who has a lower than average intellectual functioning and some limitations in adaptive skills, such as communication, socialization, and self-care. A mild mental disability may affect the client's ability to understand, cope, or cooperate with medical interventions, such as ambulation after surgery.
Ambulation is the act of walking or moving around. It is an important part of postoperative care, as it helps to prevent complications such as deep vein thrombosis, pulmonary embolism, pneumonia, atelectasis, constipation, and pressure ulcers. Ambulation also promotes circulation, wound healing, and muscle strength.
When the practical nurse (PN) atempts to assist the client to ambulate on the first postoperative day after an appendectomy, the client becomes angry and says, "PN, 'Get out of here! I'll get up when I'm ready!" This may indicate that the client is experiencing pain, fear, anxiety, or frustration due to the surgery and the recovery process .
The best response for the PN to make is to acknowledge the client's feelings, provide reassurance and support, and set a clear and realistic goal for ambulation. This will help to establish rapport, reduce resistance, and motivate the client to participate in the care plan.
Therefore, option D is the correct answer, as it shows empathy and respect for the client's feelings, while also informing the client of the expectation and time frame for ambulation. Option D also allows the client some time to prepare mentally and physically for the activity.
Correct Answer is B
Explanation
Choice A rationale:
The statement, "This medication will shorten the duration of my symptoms," is correct. Oseltamivir is an antiviral medication used to treat influenza, and it can reduce the duration of symptoms when taken early in the course of the illness.
Choice B rationale:
The statement, "This medication will prevent me from spreading the virus to others," is incorrect. While oseltamivir can help reduce the severity and duration of symptoms, it does not prevent the spread of the virus to others. Clients with influenza should still take precautions to avoid transmitting the virus to others.
Choice C rationale:
The statement, "This medication will work best if I start taking it within 48 hours of symptom onset," is correct. Oseltamivir is most effective when started within 48 hours of the onset of symptoms.
Choice D rationale:
The statement, "This medication may cause nausea and vomiting as side effects," is correct. Nausea and vomiting are potential side effects of oseltamivir, and clients should be informed about these possible adverse reactions.
