Final answer:
If epiglottitis is suspected, parents should rush to the hospital because it is a serious condition that requires immediate medical attention.
Step-by-step explanation:
If epiglottitis is suspected, the parents should be told to rush to the hospital. Epiglottitis is a serious condition where the epiglottis, a small flap of cartilage in the throat, becomes inflamed and blocks the airway. It can lead to difficulty breathing and can be life-threatening, so immediate medical attention is necessary. Encouraging hot drinks, keeping the child lying flat, or giving over-the-counter medication is not recommended and could potentially worsen the condition.
