A nurse is planning care for a toddler who has epiglottitis.

Which of the following interventions should the nurse include?

1. . Answer and explanation.

The correct answer is choice C, first-degree atrioventricular block.

This is because the PR interval is longer than normal, which indicates a delay in the conduction of electrical impulses from the atria to the ventricles through the AV node. A normal PR interval is 0.12 to 0.2 seconds, or 3 to 5 small squares on the EKG strip.

In this case, the PR interval is 0.35 seconds, which is more than 5 small squares.

Choice A is wrong because atrial fibrillation is a type of arrhythmia where the atria beat irregularly and rapidly, producing chaotic and variable P waves and an irregular ventricular response.

There is no constant PR interval in atrial fibrillation.

Choice B is wrong because complete heart block is a type of arrhythmia where there is no conduction of electrical impulses from the atria to the ventricles, resulting in independent and dissociated atrial and ventricular rhythms.

There are no consistent P waves or PR intervals in complete heart block.

Choice D is wrong because premature atrial complexes are extra beats that originate from the atria and interrupt the normal sinus rhythm.

They produce abnormal P waves that are different from the sinus P waves, and may have a shorter or longer PR interval depending on the timing of the impulse.

However, they do not cause a constant prolongation of the PR interval.

The correct answer is choice B. Continuously monitor the child’s respiratory status. This is because epiglottitis is a life-threatening condition that can cause severe airway obstruction and respiratory distress in children. The nurse should monitor the child for signs of worsening breathing, such as stridor, cyanosis, restlessness, or drooling. The nurse should also be prepared to assist with intubation or tracheostomy if needed.

Choice A is wrong because assessing the child for frequent swallowing may increase the risk of vomiting and aspiration. Swallowing may also be difficult and painful for the child due to the inflammation of the epiglottis.

Choice C is wrong because suctioning the child’s oropharynx may cause more swelling and irritation of the epiglottis, or trigger a spasm that can close off the airway. The nurse should avoid any stimulation of the throat or mouth that may worsen the condition.

Choice D is wrong because administering pancreatic enzymes with meals is not relevant to epiglottitis. Pancreatic enzymes are used to treat cystic fibrosis, a genetic disorder that affects the lungs and digestive system. Epiglottitis is caused by a bacterial infection or an injury to the throat.
