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?

A. Assessing fluid intake every 24 hr is important for a postoperative client, but it is not the priority action. The nurse should monitor fluid intake and output more frequently, such as every 8 hr or every shift, to detect any imbalances or complications.

B. Ambulating three times a day is beneficial for a postoperative client, but it is not the priority action. The nurse should encourage early and frequent ambulation to promote circulation, prevent thromboembolism, and enhance bowel function, but only after ensuring that the client is stable and has adequate pain control.

C. Assisting with deep breathing and coughing is the priority action for a postoperative client who had abdominal surgery. The nurse should help the client perform these exercises every 1 to 2 hr to prevent atelectasis, pneumonia, and respiratory failure, which are common and serious complications after abdominal surgery.

D. Monitoring the incision site for findings of infection is important for a postoperative client, but it is not the priority action. The nurse should inspect the wound for signs of infection, such as redness, swelling, warmth, drainage, or odor, but this can be done during routine dressing changes or as needed.

The client is at risk for experiencing electrolyte imbalance due to the vomiting. Persistent vomiting during pregnancy, especially with significant weight loss, can lead to electrolyte imbalances such as hypokalemia, hyponatremia, or metabolic alkalosis. This can result from the body's inability to retain essential minerals and fluids. The client’s reported diet of minimal food intake, primarily consisting of toast and pretzels, indicates inadequate nutrition and potential for further exacerbation of these imbalances.

The significant weight loss of 6.8 kg (15 lb) within a month and continuous nausea and vomiting are concerning symptoms that warrant immediate medical evaluation. The nurse’s advice to seek a provider’s assessment underscores the need for timely intervention to address potential complications, ensure maternal and fetal health, and possibly prescribe antiemetic medications or other treatments to manage symptoms.
