The practical nurse (PN) knows that AIDS is a viral infection that compromises the effectiveness of the immune system. Which component of the immune system is characteristically affected?

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: Suction equipment is essential for a client who has undergone fixation of a mandible fracture. Due to the nature of the surgery and the presence of wiring, the client may have difficulty managing oral secretions. Suction equipment ensures that any secretions can be promptly and effectively removed, preventing aspiration and maintaining a clear airway. This equipment is vital for managing the client's immediate postoperative needs and ensuring their safety.
Choice B reason: A crash cart, while critical in emergency situations, is not specifically required to be present in the client's room following mandible fracture fixation. Crash carts are typically available on the unit and can be quickly brought to the room if needed. The practical nurse should be familiar with the location of the crash cart and how to access it, but it does not need to be permanently stationed in the client's room.
Choice C reason: A non-rebreather mask is used to deliver high concentrations of oxygen to clients experiencing severe respiratory distress or hypoxemia. While it is an important piece of equipment for respiratory emergencies, it is not specifically necessary to have in the room of a client with a mandible fracture fixation. The priority is to have suction equipment and wire cutters immediately available, while other oxygen delivery devices can be accessed as needed.
Choice D reason: A nasogastric tube is used for decompression of the stomach or for feeding clients who are unable to take oral nutrition. It is not specifically required for a client with a mandible fracture fixation unless there are additional complications or indications for its use. The practical nurse should focus on equipment directly related to managing the fixation and maintaining the client's airway.
Choice E reason: Wire cutters are a critical item to have in the room of a client with a mandible fracture fixation. In the event of an emergency, such as vomiting or respiratory distress, the wires securing the mandible may need to be quickly cut to ensure the client's airway is not compromised. Having wire cutters immediately available ensures that the practical nurse can respond swiftly and effectively to any urgent situations, maintaining the client's safety and airway patency.
