A nurse is presenting a community-based program about HIV and AIDS. A client asks the nurse to describe the initial symptoms experienced with HIV infection. Which of the following manifestations should the nurse include in the explanation of initial symptoms?

Choice A rationale:
Magnet activation: Placing a magnet over the implantable device activates an on-demand feature of the VNS, delivering extra stimulation to the vagus nerve. This can potentially disrupt or shorten a seizure, especially when used at the onset of an aura (a warning sign that a seizure may be imminent).
Patient empowerment: Teaching the patient how to use the magnet provides them with a sense of control and a way to actively manage their seizures. It can reduce anxiety and improve quality of life.
Choice B rationale:
Microwave safety: While there's no definitive evidence that microwaves directly interfere with VNS devices, manufacturers generally recommend avoiding close or prolonged exposure to microwaves as a precaution. Specific guidelines may vary, but they often suggest keeping a distance of at least 15-20 inches from microwaves. The statement in Choice B about 12,000 watts or less is inaccurate and misleading.
Choice C rationale:
CT scans with contrast: There's no contraindication for patients with VNS to undergo CT scans with contrast. The device is designed to withstand common imaging procedures.
Choice D rationale:
Pain management: Burst catheters are typically used for pain management after surgery or during childbirth. They have no direct relevance to VNS therapy or seizure management.

Choice A rationale:
Urine collection from an indwelling catheter is a sterile procedure that requires aseptic technique to prevent contamination of the specimen and potential urinary tract infection. Assistive personnel (AP) may not have the necessary training in sterile technique and therefore should not be delegated this task. Additionally, the nurse needs to assess the patient for any signs of urinary tract infection or other complications before collecting the urine specimen, which is within the scope of nursing practice.

Choice B rationale:
Blood collection for PaCO2 (partial pressure of carbon dioxide) is an invasive procedure that requires assessment of the patient's condition, appropriate site selection, and proper technique to ensure accurate results. This task is within the scope of nursing practice and should not be delegated to AP.

Choice C rationale:
Wound drainage collection for culture also requires aseptic technique to prevent contamination of the specimen and ensure accurate results. The nurse needs to assess the wound for signs of infection, choose the appropriate collection method, and ensure proper labeling and transport of the specimen. This task is within the scope of nursing practice and should not be delegated to AP.

Choice D rationale:
Random stool specimen collection is a non-invasive procedure that does not require sterile technique. AP can be trained to collect random stool specimens safely and effectively, following standard precautions for handling body fluids.
