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.

Answer and Explanation

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 C

Explanation

Choice A rationale:

Nausea can be a significant factor contributing to decreased food intake, but it is not the most likely cause in this scenario. Xerostomia (dry mouth) and mucositis are mentioned as symptoms in the question stem. Nausea alone does not explain why the client is consuming less than their body requirements.

Choice B rationale:

Fatigue can also contribute to decreased food intake, but it is not the most likely cause in this case. While fatigue can be a side effect of cancer treatment and may lead to reduced appetite, the question specifically mentions xerostomia and mucositis as issues contributing to imbalanced nutritional intake.

Choice C rationale:

Pain when eating is the most likely cause of imbalanced nutritional intake in this scenario. The client's laryngeal cancer and the development of mucositis indicate that eating is likely painful for them. This discomfort can significantly deter the client from eating, leading to decreased nutritional intake.

Choice D rationale:

Altered taste sensation can affect food preferences, but it is not the most likely cause in this case. Pain when eating is a more direct and immediate barrier to food intake, especially in the context of mucositis and laryngeal cancer.

A. Discuss the character of labor from endogenous vs. exogenous oxytocin. B. Ask the healthcare provider to discuss the issue with the client. C. Discuss alternative ways to support the client's birth plan. D. Explain the indications for induction related to post-term pregnancy.

Correct Answer is C

Explanation

Choice A rationale:

Discuss the character of labor from endogenous vs. exogenous oxytocin. While it is important to educate the client about the difference between endogenous (naturally occurring) and exogenous (administered) oxytocin, this information may not address the client's primary concern. The client is refusing the prescribed oxytocin infusion and wants a "natural" delivery. Therefore, discussing alternative ways to support her birth plan is more pertinent.

Choice B rationale:

Ask the healthcare provider to discuss the issue with the client. Involving the healthcare provider in the discussion is a reasonable step, but it should not be the first action taken. The nurse can initiate a conversation with the client to explore her concerns and preferences before escalating the issue to the healthcare provider.

Choice C rationale:

Discuss alternative ways to support the client's birth plan. This is the correct choice because it directly addresses the client's refusal of the oxytocin infusion and desire for a "natural" delivery. Exploring alternative methods for inducing or facilitating labor in a way that aligns with the client's birth plan is essential.

Choice D rationale:

Explain the indications for induction related to post-term pregnancy. Explaining the indications for induction is important for educating the client about the medical reasons behind the prescribed treatment. However, this information may not immediately address the client's refusal of the oxytocin infusion. The nurse should first explore the client's concerns and preferences regarding her birth plan.
