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?

Choice A rationale:

Sodium level of 142 mEq/L is within the normal range (135-145 mEq/L) for adults. However, normal ranges for children might vary slightly, but 142 mEq/L is not indicative of dehydration on its own.

Choice B rationale:

Respiratory rate of 22/min is within the normal range for a 3-year-old child (20-30 breaths/min) This rate alone does not provide evidence of dehydration.

Choice C rationale:

Potassium level of 3.9 mEq/L is within the normal range (3.5-5.1 mEq/L) for children. Like sodium, normal ranges for potassium may differ slightly in pediatric patients, but 3.9 mEq/L is not alarming on its own.

Choice D rationale:

Heart rate of 148/min is elevated for a 3-year-old child. Tachycardia is a common sign of dehydration in pediatric patients. This increased heart rate indicates the body's compensatory mechanism to maintain cardiac output in response to decreased blood volume, a typical consequence of dehydration.

The four findings that require follow-up are B, C, E, and F.

Rationale:

1. Blood pressure: A normal blood pressure for an adolescent is 110/70 mm Hg. The question does not provide the adolescent's blood pressure, so it cannot be determined if it requires followup or not.
2. Capillary refill: A normal capillary refill time is less than 2 seconds. A prolonged capillary refill time indicates impaired blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
3. Pedal pulse: A normal pedal pulse is +2 or +3. A weak pedal pulse (+1) indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
4. Heart rate: A normal heart rate for an adolescent is 60 to 100 beats per minute. The question does not provide the adolescent's heart rate, so it cannot be determined if it requires follow-up or not.
5. Skin temperature: A normal skin temperature is warm and dry. A cool skin temperature indicates reduced blood flow to the extremity, which could be due to vascular injury, compartment syndrome, or shock.
6. Pain: A pain level of 10 on a scale of 0 to 10 indicates severe pain that needs to be managed with appropriate analgesics and nonpharmacological interventions.
