A nurse is reviewing a client's laboratory report of arterial blood gas (ABG) findings: pH 7.28, HCO3 18, and PaCO2 36. Which of the following conditions should the nurse anticipate when interpreting these findings?

Choice A reason: A fractured femur, while a serious injury, does not inherently contraindicate the use of lipid emulsions. These patients may require additional nutrition if they are unable to eat adequately by mouth, and lipid emulsions can be part of their parenteral nutrition regimen if needed.

Choice B reason: Severe anorexia nervosa is a condition that can lead to malnutrition and may necessitate the use of parenteral nutrition, including lipid emulsions, to provide essential nutrients. However, care must be taken to avoid refeeding syndrome, a potentially fatal condition that can occur when malnourished patients begin to refeed too quickly.

Choice C reason: Gastrointestinal obstruction is a condition that could be exacerbated by the administration of lipid emulsions. In cases of obstruction, enteral or parenteral nutrition may need to be carefully managed or avoided until the obstruction is resolved to prevent further complications. While lipid emulsions are a valuable component of parenteral nutrition, their use must be carefully considered in the context of the patient’s overall clinical condition. In the case of gastrointestinal obstruction, the nurse would be most concerned about the prescription of a lipid emulsion due to the potential for exacerbating the obstruction and complicating the patient’s condition.

Choice D reason: Chronic diarrhea and vomiting can lead to dehydration and electrolyte imbalances, but they do not directly contraindicate the use of lipid emulsions. However, the underlying cause of these symptoms should be addressed, and fluid and electrolyte balance should be carefully monitored.

Choice A reason:Providing oral care every 4 hours and as needed is an evidence-based practice to lower the risk of ventilator-associated pneumonia by minimizing the buildup of bacteria in the mouth³.

Choice B reason:Positioning the head of the client's bed in the flat position is not recommended as it can increase the risk of aspiration; elevating the head of the bed to 30° to 45° is the standard practice.

Choice C reason:Turning the client every 4 hours is important for preventing pressure ulcers and improving lung function but is not the primary action for reducing pneumonia risk³.

Choice D reason:Providing humidity helps to maintain mucous membrane integrity but must be carefully managed to prevent bacterial growth and is not the primary action for reducing pneumonia risk³.
