A nurse is caring for a client who reports back pain. The nurse asks the client to rate the pain on a scale of 0 to 10. The nurse is using which of the following components of the PQRST mnemonic?

A) Delayed gastric emptying: This condition refers to a slowdown in the movement of food from the stomach to the small intestine, often leading to symptoms like nausea, vomiting, bloating, and early satiety. It is not related to breath sounds and would not be detected through auscultation of the lungs.

B) Atelectasis: This condition involves the collapse or closure of lung tissue, resulting in reduced or absent gas exchange. It commonly occurs in patients who are immobile or on bedrest for extended periods, such as the client with a lacerated spleen. Decreased breath sounds in the lower lobes of the lungs are a typical finding in atelectasis, as the collapsed or partially collapsed alveoli do not allow air to move through them, leading to diminished or absent breath sounds in the affected areas.

C) An upper respiratory infection: This condition involves infections in the nose, throat, and airways and typically presents with symptoms like cough, nasal congestion, sore throat, and sometimes fever. It can affect breath sounds, but it more commonly causes wheezing, crackles, or rhonchi rather than isolated decreased breath sounds in the lower lobes.

D) Pulmonary edema: This condition is characterized by the accumulation of fluid in the lungs, often due to heart failure or acute lung injury. Auscultation findings typically include crackles or rales, particularly in the lower lung fields, but not necessarily decreased breath sounds unless there is a significant consolidation or fluid volume.

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.
