The nurse is caring for a pediatric client with a new onset of hypercalcemia.
What condition would be most likely to cause this altered serum calcium level?
Liver failure.
Radiation injury.
Malignancy.
Hypothyroidism.
The Correct Answer is C
Hypercalcemia is a condition caused by having too much calcium in the blood, which can affect the function of nerves, muscles, kidneys and heart. Hypercalcemia can occur in children due to various causes, both acquired and genetic. One of the most common causes of hypercalcemia in children is cancer, especially cancers that affect the bones or produce substances that mimic parathyroid hormone (PTH), which regulates calcium levels.
Choice A is wrong because liver failure does not directly cause hypercalcemia, although it can affect vitamin D metabolism and calcium absorption.
Choice B is wrong because radiation injury does not cause hypercalcemia, unless it damages the parathyroid glands or causes bone destruction.
Choice D is wrong because hypothyroidism does not cause hypercalcemia, although it can affect bone turnover and calcium excretion.

Correct Answer is A
Explanation
Diaphoresis means excessive sweating, which is one of the symptoms of hypoglycemia. Hypoglycemia occurs when the blood sugar level is lower than the normal range, which can cause dizziness, confusion, weakness, hunger, and other signs.
Choice B is wrong because flushing of the face is not a symptom of hypoglycemia.
Flushing can be caused by other conditions, such as fever, allergic reactions, or rosacea.
Choice C is wrong because fruity breath is a symptom of hyperglycemia, not hypoglycemia.
Hyperglycemia means high blood sugar level, which can cause the body to produce ketones that give the breath a fruity odor.
Choice D is wrong because unpredictable behaviors are not a specific symptom of hypoglycemia.
However, hypoglycemia can cause confusion, irritability, or anxiety, which may affect the behavior of some people.
The normal range of blood sugar level for most people is between 70 and 130 mg/dL (3.9 and 7.2 mmol/L) before meals and less than 180 mg/dL (10 mmol/L) after meals.
However, this may vary depending on the individual and the type of diabetes.
It is important to monitor the blood sugar level regularly and treat hypoglycemia promptly by eating or drinking a simple sugar source.
Correct Answer is C
Explanation
The nurse would assess these factors to determine the need for therapy. Some possible explanations for the other choices are:
Choice A. Number of times client’s family reports the client is nauseated.
This is not a reliable indicator of the severity or cause of nausea and vomiting.
The nurse should assess the client directly and not rely on the family’s reports.
Choice B. How well the client is eating.
This is not a specific or objective measure of nausea and vomiting.
The client may have other reasons for not eating well, such as loss of appetite, taste changes, or pain.
The nurse should also monitor the client’s weight, hydration status, and electrolyte levels.
Choice D. Client’s nutritional status and fluid balance.
These are important aspects of the client’s overall health, but they are not directly related to nausea and vomiting.
The nurse should assess these factors as part of the comprehensive care plan, but they are not sufficient to determine the need for therapy.
