A nurse is assessing a client who has major depressive disorder and is taking amitriptyline.

Which of the following findings should the nurse identify as an adverse effect of the medication?

Electrolyte imbalance in pregnant clients is often associated with conditions that lead to dehydration and nutritional deficiencies. In this scenario, the key indicators are persistent nausea and significant weight loss.

• Persistent nausea can lead to reduced food and fluid intake. This condition, especially if prolonged, can cause dehydration and electrolyte imbalances due to the loss of essential minerals and nutrients that are not being replenished due to inadequate dietary intake.
• Significant weight loss, particularly the amount described in the scenario (6.8 kg or 15 lb), is a clear sign of inadequate nutritional intake and can further exacerbate the risk of electrolyte imbalance. It indicates that the body is not receiving enough nutrients, which is crucial for maintaining electrolyte balance.

The other options, while related to diet and fluid intake, are more specific to the client's eating habits and do not directly point to the primary cause of potential electrolyte imbalance in the context of this scenario. Therefore, the most comprehensive and medically relevant choice is (A) Persistent nausea and significant weight loss.

- 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.
