A nurse is completing a focused assessment addressing a client's immune function. What should the nurse prioritize in the physical assessment?

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:
Coughing and deep breathing: These techniques directly promote airway clearance by mobilizing and expelling secretions from the lungs. They are essential for clients with pneumonia, as the buildup of secretions can obstruct the airways and impair gas exchange.
Hydration maintenance: Adequate hydration helps to thin secretions, making them easier to cough up and clear from the lungs. It also helps to prevent dehydration, which can worsen respiratory symptoms.

Choice B rationale:
Keeping the head of the bed elevated: This can help to improve breathing by decreasing the work of breathing and promoting lung expansion. However, it is not the most effective intervention for directly clearing secretions from the lungs.

Choice C rationale:
Preparation for insertion of a tracheostomy tube: This is a more invasive intervention that may be necessary in severe cases of airway obstruction. However, it is not the priority intervention for a client with ineffective airway clearance related to pneumonia.

Choice D rationale:
Providing supplemental oxygen: This can help to improve oxygenation in clients with pneumonia. However, it does not directly address the problem of ineffective airway clearance.
