The nurse is caring for a client who had an appendectomy 4 hours ago. Which finding requires immediate action by the nurse?

Choice A reason: This is incorrect because sleeping with the head ofthe bed flat can worsen OSA by allowing gravity to pull down on the soft tissues ofthe throat and obstructing airflow.

Choice B reason: This is incorrect because taking sedatives prior to sleep can also worsen OSA by relaxing the muscles ofthe upper airway and increasing airway collapse.

Choice C reason: This is correct because beginning a weight loss program can help reduce OSA by decreasing fat deposits around the neck and chest that can compress and narrow the airway.

Choice D reason: This is incorrect because drinking 1to 2 glasses of wine at bedtime can have similar effects as sedatives, such as relaxing the muscles ofthe upper airway and impairing the respiratory drive.

Choice A reason: This is incorrect because reviewing the need for pneumococcal vaccine is not the most important intervention for the nurse to implement. Pneumococcal vaccine is recommended for people who are at high risk of pneumococcal infections, such as those with chronic diseases or immunosuppression. However, it is not a priority action for a client with neutropenia, which is a low number of neutrophils that increases the risk of bacterial and fungal infections.

Choice B reason: This is incorrect because implementing bleeding precautions is not the most important intervention for the nurse to implement. Bleeding precautions are indicated for clients who have thrombocytopenia, which is a low number of platelets that impairs blood clotting. However, this is not the case for a client with neutropenia, which affects the white blood cells that fight infections.

Choice C reason: This is incorrect because assessing vital signs every 4 hours is not the most important intervention for the nurse to implement. Vital signs are important indicators of the client's health status and may reveal signs of infection, such as fever, tachycardia, or hypotension. However, this is not a sufficient measure to prevent or treat infections in a client with neutropenia, who needs more aggressive and proactive interventions.

Choice D reason: This is correct because placing the client in protective isolation is the most important intervention for the nurse to implement. Protective isolation, also known as reverse isolation or neutropenic precautions, is a set of measures that aim to protect the client from exposure to pathogens that may cause infections. These include wearing gloves, masks, gowns, and eye protection; using sterile equipment and techniques; avoiding contact with people who are sick or have infections; and restricting visitors and fresh flowers or fruits.
