The nurse is performing a functional assessment on an older client who lost five pounds (2.27 Kg) of weight since the last visit 12 weeks ago, and who reports a decrease in energy and appetite. Which action should the nurse include during the assessment?

A) Incorrect- While a second IV site might be considered if the first one is causing significant discomfort, it's not the initial intervention. The nurse should first address the immediate concern of pain.
B) Correct- Pain at the IV site during infusion might indicate infiltration or irritation. Stopping the infusion is the most immediate intervention to prevent further discomfort and potential complications like tissue damage.
C) Incorrect- While assessing for blood return is important to ensure proper IV placement, it's not the initial intervention for managing pain caused by the infusion.
D) Incorrect- Discontinuing the IV might be considered if the pain is severe and unmanageable, but the nurse should initially try to address the discomfort without removing the IV.

- 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 humans¹². Humans can incorporate Neu5Gc from their diet into their own cells, which can trigger an immune response and the production of AGNA¹².

- AGNA has been associated with various inflammatory and autoimmune diseases, such as atherosclerosis, rheumatoid arthritis, Crohn's disease, and cancer¹². AGNA may also play a role in the rejection of bioprosthetic heart valves, which are made from animal tissues that contain Neu5Gc¹.

- 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 expression¹². 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 the 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.
