A mother with a diagnosis of AIDS states that she has been caring for her baby even though she has not been feeling well.
What important information should the nurse determine?

Choice A rationale:
Acute retroviral syndrome (ARS) is an early stage of HIV infection that often presents with flu-like symptoms. It does not determine AIDS diagnosis.

Choice B rationale:
A CD4+ T lymphocyte level of less than 200 cells/mm is a defining criterion for AIDS diagnosis. This low count indicates a severely weakened immune system, leading to susceptibility to opportunistic infections and other AIDS-defining illnesses.

Choice C rationale:
A person with HIV can transmit the virus to others regardless of their CD4+ T cell count. Transmission risk is not a diagnostic criterion for AIDS.

Choice D rationale:
HIV-specific antibodies are produced by the immune system in response to HIV infection but their presence does not signify AIDS progression.

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.
