A nurse is caring for a toddler who has acute laryngotracheobronchitis and has been placed in a cool mist tent. Which of the following findings should indicate to the nurse that the treatment is effective?

Choice A reason: Applying and releasing elbow restraints every hour prevents the infant from touching or injuring the surgical site, while allowing some movement and circulation. This is a standard nursing intervention for infants who have undergone cleft palate repair.

Choice B reason: Keeping the infant supine is not recommended, as it increases the risk of aspiration and bleeding. The infant should be placed in a side-lying or upright position to facilitate drainage and prevent pressure on the suture line.

Choice C reason: Feeding the infant with a spoon for 48 hours is not necessary, as it may cause discomfort and trauma to the palate. The infant can be fed with a special nipple or a syringe with a rubber tip that delivers small amounts of formula or breast milk to the side of the mouth.

Choice D reason: Suctioning the mouth with an oral suction tube is contraindicated, as it may damage the palate and cause bleeding or infection. The nurse should use a bulb syringe to gently suction the nose and mouth if needed.

Choice A reason: A 13% weight loss is a sign of severe dehydration in infants. Dehydration occurs when the body loses more fluid than it takes in. Acute gastroenteritis can cause vomiting and diarrhea, which can lead to fluid loss and dehydration.

Choice B reason: A bulging anterior fontanel is not a sign of dehydration, but rather a sign of increased intracranial pressure. The anterior fontanel is the soft spot on the top of the infant's head. It should be flat or slightly concave, not bulging or sunken.

Choice C reason: Bradypnea is not a sign of dehydration, but rather a sign of respiratory depression. Bradypnea is abnormally slow breathing, usually less than 12 breaths per minute in infants. Dehydration can cause tachypnea, which is abnormally fast breathing, usually more than 60 breaths per minute in infants.

Choice D reason: A capillary refill of 3 seconds is not a sign of dehydration, but rather a sign of normal perfusion. Capillary refill is the time it takes for the color to return to the nail bed after pressing on it. A normal capillary refill is less than 2 seconds. Dehydration can cause delayed capillary refill, which is more than 2 seconds.
