A client is admitted with the diagnosis of possible pneumonia, and laboratory studies are prescribed to rule out the etiology. Which specimen should the practical nurse (PN) collect prior to the beginning of antibiotic therapy?

Choice A reason: Smoking two packs of cigarettes a day is highly significant in planning the client's rehabilitation following a myocardial infarction. Smoking is a major risk factor for cardiovascular disease, and continuing to smoke can significantly hinder recovery and increase the risk of future cardiac events. Addressing this behavior is crucial for improving the client's long-term health outcomes. Smoking cessation should be a primary focus of the rehabilitation plan, and the client should be provided with resources and support to quit smoking, such as counseling, nicotine replacement therapy, or medications.
Choice B reason: Expressing a desire to change one's lifestyle is a positive and encouraging sign. It indicates the client's motivation to adopt healthier habits, which is essential for successful rehabilitation. However, while this is important, the immediate focus should be on addressing specific risk factors, such as smoking, that have a direct and significant impact on the client's recovery and future health. The desire to change is a valuable component of the rehabilitation process, but it should be coupled with targeted interventions to address critical behaviors like smoking.
Choice C reason: Drinking 1 to 2 glasses of red wine daily may have both positive and negative health implications. Moderate alcohol consumption has been suggested to have some cardiovascular benefits, but it can also pose risks, especially if not monitored. While this information is relevant to the client's overall lifestyle, it is not as immediately critical as addressing smoking, which has a well-documented and direct impact on cardiovascular health. The client's alcohol consumption can be discussed as part of the broader lifestyle changes during rehabilitation.
Choice D reason: Walking four city blocks to work each day indicates a level of physical activity that is beneficial for cardiovascular health. Encouraging regular physical activity is an essential part of the rehabilitation process. However, compared to the impact of smoking, this information is less critical in the immediate planning of the client's rehabilitation. The focus should be on eliminating harmful behaviors like smoking, while also promoting continued and possibly increased physical activity as part of a comprehensive rehabilitation plan.

Choice A reason: Administering a PRN prescription for an antiemetic is not the first action to take in this situation. Shaking and feelings of nausea and vomiting during a blood transfusion can indicate a possible transfusion reaction, which is a serious and potentially life-threatening event. While managing symptoms like nausea is important, the immediate priority is to stop the transfusion to prevent further complications.
Choice B reason: Flushing the IV tubing with sodium chloride is not the appropriate first step. Before addressing the IV line, it is crucial to stop the blood infusion to prevent any more blood from entering the client's system, which could exacerbate a potential transfusion reaction. After stopping the infusion, flushing the line can be considered to maintain IV access, but it is not the initial action to take.
Choice C reason: Notifying the healthcare provider is necessary, but it is not the first action to take. Immediate intervention is required to prevent further administration of the potentially problematic blood product. Once the infusion is stopped, the healthcare provider should be notified promptly so that appropriate assessments and interventions can be initiated.
Choice D reason: Turning off the blood infusion is the first and most critical action to take. This step immediately stops the administration of the blood product, preventing further exposure to the potential cause of the reaction. Once the infusion is stopped, the PN can then proceed to assess the client's vital signs, notify the healthcare provider, and follow the institution's protocol for managing transfusion reactions. Ensuring the client's safety by stopping the infusion is the top priority.
