A nurse is teaching a newly licensed nurse about wearing medical masks. Which of the following statements should the nurse include?

A. Delayed gastric emptying (gastroparesis) typically manifests with symptoms related to the gastrointestinal system, such as nausea, vomiting, bloating, and early satiety. It does not cause changes in lung auscultation findings.
B. Pulmonary edema is characterized by the accumulation of fluid in the lungs, leading to symptoms such as shortness of breath, crackles (rales) on lung auscultation, and possibly decreased oxygen saturation. While pulmonary edema can cause abnormal lung sounds, it is less likely in a client recovering from a lacerated spleen unless there are additional complications or comorbidities.
C. Atelectasis refers to the collapse or closure of a part of the lung, resulting in reduced or absent air exchange. It can occur due to prolonged bedrest, shallow breathing, or conditions that restrict lung expansion. A client who has been on bedrest for several days is at increased risk for developing atelectasis, especially in the lower lobes where ventilation may be compromised. Decreased breath sounds in the lower lobes suggest atelectasis as a likely condition.
D. An upper respiratory infection typically affects the upper airways (nose, throat, sinuses), causing symptoms such as nasal congestion, sore throat, cough, and sometimes fever. Lung auscultation findings in an upper respiratory infection are more likely to include rhonchi or wheezes rather than decreased breath sounds in the lower lobes.

A. Notifying the laboratory is not the first action to take in this situation. While it's important to inform the laboratory about suspected transfusion reactions for further investigation and documentation, immediate patient care takes precedence to ensure the client's safety.

B. This is the correct action to take first. Stopping the infusion of blood is crucial to prevent further administration of the potentially harmful blood product. Suspecting an acute hemolytic reaction (symptoms like chills, back pain, and hypotension) necessitates immediate cessation of the transfusion to minimize complications.
C. Obtaining a urine specimen may be indicated later to assess for hemolysis and kidney function, but it is not the first action to take. The priority is to stop the transfusion and assess the client's condition to manage the suspected transfusion reaction.
D. While it's important to notify the provider promptly, stopping the transfusion (option B) is the first critical action to take in response to suspected acute transfusion reactions. The provider will need to be informed for further orders and management, but immediate cessation of the transfusion is essential to prevent worsening of the client's condition.
