The nurse is preparing an adolescent for discharge after a cardiac catheterization. Which statement by the adolescent would indicate the need for further teaching?

The correct answer is choice D. Epiglottitis.

Choice A rationale:

Laryngotracheobronchitis (LTB) is a viral infection commonly known as "croup." While it can cause airway inflammation and respiratory distress, it is usually not considered a medical emergency. LTB is characterized by barking cough, stridor, and hoarseness. It typically responds well to supportive care, humidity, and sometimes oral corticosteroids.

Choice B rationale:

Spasmodic croup is another type of viral croup, often triggered by allergies or irritants. It is characterized by sudden onset of symptoms, usually at night, including stridor and a barking cough. While it can be distressing, it is generally not considered a medical emergency. It usually responds to humidity and sometimes oral corticosteroids.

Choice C rationale:

Laryngitis involves inflammation of the larynx and is often caused by viral infections or excessive voice use. While it can lead to hoarseness and voice changes, it does not typically cause severe respiratory distress and is not considered a medical emergency. Resting the voice and staying hydrated are common interventions.

Choice D rationale:

Epiglottitis is a potentially life-threatening condition that causes inflammation of the epiglottis, a flap of tissue that prevents food from entering the windpipe during swallowing. It can rapidly progress to airway obstruction and respiratory failure. Children with epiglottitis often assume a "tripod" position, leaning forward to maintain an open airway. Immediate medical intervention, including securing the airway and administering antibiotics, is crucial.

The correct answers are choices C. Novolin R, and D. NovoLog.

Choice A rationale:

Novolin N is an intermediate-acting insulin, not rapid or short acting. It has a slower onset and longer duration of action, making it unsuitable for rapid blood sugar control.

Choice B rationale:

Lantus is a long-acting insulin that provides basal insulin coverage and has a relatively steady effect over 24 hours. It is not rapid or short acting and is used to provide a baseline level of insulin, not for immediate blood sugar control.

Choice C rationale:

Novolin R, also known as regular insulin, is a short-acting insulin with an onset of about 30 minutes and a peak effect around 2 to 3 hours. It is often used to cover mealtime blood sugar elevations and is suitable for short-term blood sugar control.

Choice D rationale:

NovoLog is a rapid-acting insulin analog with an onset of about 15 minutes and a peak effect within 1 to 2 hours. It is designed to mimic the body's rapid insulin release after meals, making it effective for controlling postprandial blood sugar levels.
