A nurse is completing discharge teaching to a patient who has seizures and received a vagal nerve stimulator to decrease seizure activity. Which of the following statements should the nurse include in the teaching?

You should place a magnet over the implantable device when you feel an aura occurring

It's safe to use a microwave that is 12,000 watts or less

You should avoid the use of CT scan with contrast

It's recommended that you use a burst catheter for pain management .

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is A

Explanation

Choice A rationale:
Lymph nodes are small, bean-shaped structures that play a crucial role in the immune system. They filter lymph fluid, which carries white blood cells and other immune cells throughout the body.
When the body is fighting an infection or other immune challenge, lymph nodes often swell and become tender. This is because they are actively working to filter out pathogens and activate immune cells.
Palpation of the lymph nodes can provide valuable information about the patient's immune function. The nurse can assess for enlargement, tenderness, and mobility of the lymph nodes.
Lymph node assessment is a non-invasive, painless procedure that can be performed quickly and easily.
Choice B rationale:
Auscultation of the apical heart rate is important for assessing cardiovascular function, but it does not directly assess immune function.
While heart rate can be indirectly affected by certain immune conditions (e.g., fever), it is not a primary indicator of immune system activity.
Choice C rationale:
Palpation of the liver can provide information about liver size and consistency, but it does not directly assess immune function.
The liver plays a role in immune function by producing proteins that help fight infection, but its size and consistency do not necessarily reflect its immune activity.
Choice D rationale:
Percussion of the abdomen can be used to assess the size and location of abdominal organs, but it does not directly assess immune function.
While certain immune conditions may involve abdominal organs (e.g., splenomegaly), percussion is not a primary method for assessing immune function.

A. Candidiasis B. Xerostomia C. Halitosis D. Gingivitis

Correct Answer is A

Explanation

Choice A rationale:
Candidiasis, also known as thrush, is a fungal infection caused by Candida albicans. It commonly affects the mouth, causing white patches on the tongue, inner cheeks, gums, or tonsils.
Individuals with AIDS often have weakened immune systems due to a decreased CD4 T-cell count. This makes them more susceptible to opportunistic infections like candidiasis.
The fungal infection can spread to the esophagus, causing difficulty swallowing, or even to the bloodstream, leading to more serious complications.
Choice B rationale:
Xerostomia refers to dry mouth. It can be caused by various factors, including medications, salivary gland dysfunction, or radiation therapy. While it can occur in individuals with AIDS, it's not directly linked to a decreased CD4 T-cell count.
Choice C rationale:
Halitosis, or bad breath, can have multiple causes, including poor oral hygiene, gum disease, or digestive issues. It's not specifically associated with AIDS or a decreased CD4 T-cell count.
Choice D rationale:
Gingivitis is inflammation of the gums, often caused by plaque buildup. It's a common condition, but it's not directly linked to AIDS or a decreased CD4 T-cell count.
