A nurse is teaching a class about aromatherapy. The nurse should include that which of the following essential oils can promote sleep

A) Contact: While contact precautions are important for preventing the transmission of infections, they primarily apply to clients with known or suspected infections that can spread through direct or indirect contact with the client or their environment. Protective isolation goes beyond contact precautions and involves comprehensive measures to protect immunocompromised clients from all potential sources of infection.

B) Airborne: Airborne precautions are necessary for clients with infections that spread through the airborne route, such as tuberculosis or measles. While respiratory infections can pose a significant risk to immunocompromised clients, the focus of care for clients after hematopoietic stem-cell transplant is on preventing all types of infections, not just airborne ones.

C) Droplet: Droplet precautions are used for infections transmitted through respiratory droplets expelled when a person coughs, sneezes, or talks, such as influenza or pertussis. While respiratory infections are a concern for immunocompromised clients, the broader approach of protective isolation is more appropriate for clients after hematopoietic stem-cell transplant, as it encompasses all potential routes of infection transmission, not just droplet spread.

D) Protective: Clients who have undergone allogeneic hematopoietic stem-cell transplant are profoundly immunocompromised due to the destruction of their immune system and are highly susceptible to infections. Protective isolation, also known as reverse isolation, is necessary to minimize the risk of infection in these clients. This includes implementing strict infection control measures such as wearing gowns, gloves, masks, and sometimes goggles to prevent exposure to pathogens. Additionally, maintaining a clean environment and limiting visitors and healthcare personnel who may carry infectious agents are essential components of protective isolation.

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.
