A nurse is caring for a client who is taking valproic acid for seizure control. For which of the following adverse effects should the nurse monitor and report?

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.

Choice A rationale:

Beginning ball squeezing exercises is not advisable immediately after a modified radical mastectomy. The client's arm on the affected side needs time to heal, and strenuous exercises can strain the surgical site, increase pain, and potentially disrupt the healing process.

Choice B rationale:

Wearing a bra with wire support is not recommended, especially in the early postoperative period. Underwire bras can irritate the surgical site and interfere with the healing process. Patients are usually advised to wear soft, non-underwire bras or special post-surgical bras designed for comfort and support.

Choice C rationale:

Avoiding the use of the affected arm for eating is the correct instruction. Protecting the surgical site and preventing strain is essential for proper healing. Encouraging the client to use the opposite arm for activities like eating can minimize movement in the affected area, reducing the risk of complications.

Choice D rationale:

Using deodorant under the affected arm is not recommended immediately after surgery. The surgical site needs to be kept clean and dry to prevent infection and promote healing. Deodorants, especially those containing chemicals or fragrances, can irritate the skin and increase the risk of complications. Patients are usually advised to avoid applying any products to the surgical area until it is fully healed.
