A nurse is caring for a 3-year-old toddler who has dehydration.
Which of the following findings should the nurse report to the provider?
Sodium 142 mEq/L.
Respiratory rate 22/min.
Potassium 3.9 mEq/L.
Heart rate 148/min.
The Correct Answer is D
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.

Correct Answer is A
Explanation
- A. Correct. The nurse should initiate seizure precautions for a client who is at 33 weeks of gestation and has severe gestational hypertension, which is a blood pressure of 160/110 mm Hg or higher on two occasions at least 4 hr apart, or once with signs of end-organ damage. Severe gestational hypertension can lead to preeclampsia, which is a condition characterized by hypertension, proteinuria, and edema, and can progress to eclampsia, which is a lifethreatening complication that involves seizures.
- B. Incorrect. The nurse does not need to initiate seizure precautions for a client who is at 16 weeks of gestation and has a hydatidiform mole, which is an abnormal growth of placental tissue that resembles grape-like clusters. A hydatidiform mole can cause vaginal bleeding, hyperemesis gravidarum, and elevated human chorionic gonadotropin levels, but it does not increase the risk of seizures.
- C. Incorrect. The nurse does not need to initiate seizure precautions for a client who is at 28 weeks of gestation and is experiencing vaginal bleeding, which can have various causes such as placenta previa, placental abruption, or cervical trauma. Vaginal bleeding can indicate a potential hemorrhage, but it does not increase the risk of seizures.
- D. Incorrect. The nurse does not need to initiate seizure precautions for a client who is at 36 weeks of gestation and has a positive group B streptococcal culture, which means that the client has bacteria in their vagina or rectum that can cause infection in the newborn during delivery. A positive group B streptococcal culture requires antibiotic prophylaxis during labor, but it does not increase the risk of seizures.
Correct Answer is A
Explanation
Irritability.

The rationale for each choice is as follows:
- A. Irritability: Correct. Irritability is one of the signs of hypoglycemia, which occurs when blood glucose levels fall below 70 mg/dL (3.9 mmol/L). Other signs include shakiness, sweating, hunger, headache, confusion, and blurred vision.
- B. Increased urination: Incorrect. Increased urination is one of the signs of hyperglycemia, which occurs when blood glucose levels rise above 180 mg/dL (10 mmol/L). Other signs include thirst, dry mouth, fatigue, nausea, and fruity breath odor.
- C. Vomiting: Incorrect. Vomiting is not a specific sign of hypoglycemia or hyperglycemia, but it can occur as a complication of either condition if left untreated or poorly managed.
- D.Facial flushing: Incorrect. Facial flushing is not a sign of hypoglycemia or hyperglycemia, but it can occur as a side effect of some medications used to treat diabetes, such as niacin or rosiglitazone.
