A nurse is assisting with the admission of a child who has measles. Which of the following isolation precautions should the nurse initiate?

Choice A: This statement is correct, as the mother should notify the doctor if the child's temperature is not controlled with acetaminophen, which is an antipyretic and analgesic medication that can lower fever and relieve pain. A high fever can increase the child's metabolic rate and insulin requirements, which can lead to hyperglycemia or ketoacidosis.

Choice B: This statement is incorrect, as the mother should check the child's blood sugar more frequently than two times every day, especially when the child is sick. An upper respiratory infection can cause inflammation and stress hormones, which can increase the child's blood sugar levels and insulin needs. The mother should monitor the child's blood sugar at least four times a day or more often if indicated by symptoms or ketone testing.

Choice C: This statement is correct, as the mother should encourage the child to drink half a cup of water or sugar-free fluids every 30 minutes, which can prevent dehydration and flush out excess glucose and ketones from the body. Dehydration can worsen hyperglycemia and ketoacidosis, which are serious complications of diabetes.

Choice D: This statement is correct, as the mother should report a change in the child's breathing or any signs of confusion, which can indicate respiratory distress or cerebral edema. Respiratory distress can occur due to hypoxia or acidosis, which can impair oxygen delivery and carbon dioxide elimination. Cerebral edema can occur due to fluid shifts or electrolyte imbalances, which can cause increased intracranial pressure and neurological impairment.

Choice A: Nausea and vomiting are not common signs of hypoglycemia, which is a low blood glucose level. Nausea and vomiting are more likely to occur with hyperglycemia, which is a high blood glucose level, or with diabetic ketoacidosis, which is a life-threatening complication of diabetes.

Choice B: Sweating is not a common sign of hyperglycemia, but rather a sign of hypoglycemia. Sweating occurs as a result of the activation of the sympathetic nervous system, which tries to raise the blood glucose level by releasing adrenaline and other hormones.

Choice C: The onset of low blood glucose usually occurs quickly, not slowly. Low blood glucose can be caused by taking too much insulin, skipping meals, exercising too much, or drinking alcohol. Low blood glucose can lead to confusion, seizures, coma, or death if not treated promptly.

Choice D: Feeling shaky is a common sign of hypoglycemia, as the body tries to cope with the lack of glucose as an energy source. Feeling shaky can also be accompanied by other signs such as hunger, nervousness, dizziness, or weakness.
