The practical nurse (PN) is assisting with blood pressure measurement for adults at a community health fair. Which blood pressure measurement requires the most immediate action by the PN?

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.

Choice A reason: Lymph nodes are important components of the immune system and play a crucial role in filtering harmful substances and housing lymphocytes. While HIV/AIDS can affect lymph nodes, it is not the primary target of the virus.
Choice B reason: The spleen is another vital organ in the immune system that helps filter blood and fight infections. However, it is not the specific target of HIV.
Choice C reason: T cells, specifically CD4+ T cells, are the main target of HIV (the virus that causes AIDS). HIV infects and destroys these cells, leading to a weakened immune system. The progressive loss of CD4+ T cells impairs the body's ability to fight off infections and certain cancers, which is characteristic of AIDS.
Choice D reason: B cells are responsible for producing antibodies and play a key role in the humoral immune response. While HIV/AIDS can indirectly impact B cell function due to the overall compromised immune system, B cells are not the primary cells affected by the virus.
