A nurse is caring for an older adult client. The nurse informs the client that straining while defecating can cause which of the following?

B) Placing clean linen that touched the floor in the soiled linen bag: This action demonstrates an understanding of infection control principles because it prevents cross-contamination between clean and soiled linens. Placing clean linens that have come into contact with the floor in the soiled linen bag reduces the risk of spreading pathogens and maintains a clean environment for the client.

A) Placing the soiled linen on the floor before bagging it: This action increases the risk of contamination by exposing the linen to potentially contaminated surfaces. Placing soiled linen on the floor can spread pathogens and is not consistent with infection control practices.

C) Holding the soiled linen against her body while carrying it to the linen bag: This action increases the risk of contamination to the AP's clothing and skin. Contact with soiled linen can transfer pathogens to the caregiver's body, leading to the potential spread of infection.

D) Shaking the soiled linen to remove any toilet paper remnants: This action can aerosolize fecal matter and spread pathogens into the air and onto nearby surfaces. Shaking soiled linen increases the risk of contamination and is not recommended as part of infection control practices.

The rationale for identifying the client as at risk for hypoxia is based on the respiratory assessment findings. Diminished lung sounds in the posterior lobes suggest reduced air movement or potential complications such as atelectasis or pneumonia, which can impair gas exchange. Additionally, the decreased oxygen saturation of 84% on room air indicates inadequate oxygenation of the blood. Hypoxia occurs when there is insufficient oxygen supply to tissues, which can lead to serious complications if not addressed promptly. Therefore, recognizing these respiratory assessment findings is crucial for identifying the risk of hypoxia in the client.
