A nurse is planning care for a 4-year-old child who requires airborne precautions. Which of the following activities should the nurse plan for the child?

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 reason: This choice is incorrect because the radial artery is not an ideal site to assess the heart rate in an infant. The radial artery is located on the thumb side of the wrist, and it can be palpated by placing two fingers over it. It may be used for adults or older children who have a strong pulse, but it may be difficult to locate or feel in an infant who has a small or weak pulse.

Choice B reason: This choice is incorrect because the carotid artery is not an ideal site to assess the heart rate in an infant. The carotid artery is located on either side of the neck, and it can be palpated by placing two fingers over it. It may be used for adults or older children who have a cardiac arrest or shock, but it may be risky to use in an infant who has a fragile neck or airway.

Choice C reason: This choice is incorrect because the brachial artery is not an ideal site to assess the heart rate in an infant. The brachial artery is located on the inner side of the upper arm, and it can be palpated by placing two fingers over it. It may be used for infants or young children who have a blood pressure measurement, but it may be uncomfortable or inaccurate to use for a heart rate assessment.

Choice D reason: This choice is correct because the apex of the heart is an ideal site to assess the heart rate in an infant. The apex of the heart is located at the fifth intercostal space on the left midclavicular line, and it can be auscultated by placing a stethoscope over it. It may be used for infants or young children who have a regular and strong heartbeat, and it may provide the most accurate measurement of the heart rate.
