A nurse is caring for a school-age child who is taking valproic acid. The nurse should expect the provider to order which of the following diagnostic tests?

• Anti-Glycan Neu5Gc Antibodies (AGNA) are antibodies that recognize a carbohydrate antigen called N- glycolylneuraminic acid (Neu5Gc), which is found in animal-derived foods and tissues, but not in humans. Humans can incorporate Neu5Gc from their diet into their own cells, which can trigger an immune response and the production of AGNA.
• AGNA have been associated with various inflammatory and autoimmune diseases, such as atherosclerosis, rheumatoid arthritis, Crohn's disease, and cancer. AGNA may also play a role in the rejection of bioprosthetic heart valves, which are made from animal tissues that contain Neu5Gc.
• A client with carcinoma in situ of the left breast is a client with a non-invasive form of breast cancer, where the abnormal cells are confined to the ducts or lobules of the breast. This type of cancer has a high chance of cure with surgery and/or radiation therapy.
• Increased levels of AGNA in a client with carcinoma in situ of the left breast may indicate that the client has an increased risk of inflammation and infection, as AGNA can activate the complement system and recruit inflammatory cells to the site of Neu5Gc expression. This may impair the healing process and increase the chances of complications after surgery or radiation therapy.

Therefore, the practical nurse (PN) should anticipate that the client's plan of care will include initiation of changes in infection control measures, such as prophylactic antibiotics, wound care, sterile dressing changes, and monitoring for signs and symptoms of infection (such as fever, redness, swelling, pain, or pus). These measures will help to prevent or treat any potential infection and promote wound healing.

Therefore, option A is the correct answer, while options B, C, and D are incorrect.

Option B is incorrect because increasing the client's dietary servings of fruits and vegetables may not have a significant impact on the levels of AGNA or Neu5Gc in the client's body.

Option C is incorrect because limiting the client's fluid intake to avoid hemodilution may not be necessary or beneficial for the client's condition.

Option D is incorrect because avoiding the client's exposure to cold temperatures may not be relevant or helpful for the client's condition.

Choice A reason:

Allow the client's partner to translate. While the partner may be well-intentioned, using a family member or friend as an ad-hoc interpreter can compromise the confidentiality of the information and may not accurately convey the client's medical concerns.

Choice B reason:

Have the client's child translate. Relying on a child to translate sensitive medical information is inappropriate, as it may burden the child and may lead to potential misunderstandings or omissions in communication.

Choice C reason:

Ask a nursing student who speaks the same language as the client to translate. Although a nursing student who speaks the same language as the client may be able to assist, using a professional interpreter is the preferred option. Professional interpreters have specific training in medical terminology and communication, ensuring the most accurate and effective exchange of information.

Choice D reason:

Using a professional interpreter is essential in situations where the healthcare provider and the client do not speak the same language. It ensures accurate communication, maintains confidentiality, and prevents misunderstandings. In this scenario, the nurse should request an interpreter who is proficient in the client's language to assist with the admission process.
