Which of the following are expected assessment findings in a child with congestive heart failure (CHF)?

Choice A rationale

Cyanosis, a bluish discoloration of the skin and mucous membranes, indicates significant hypoxemia (low oxygen saturation) and is a sign of severe, life-threatening asthma exacerbation, not a mild to moderate presentation. In mild to moderate asthma, the body can usually compensate to maintain adequate tissue oxygenation despite airway constriction and inflammation.

Choice B rationale

Chest tightness is a subjective but common symptom in asthma, resulting from the bronchoconstriction and smooth muscle spasm that narrow the airways. The sensation is often described as a band around the chest, reflecting the increased work of breathing and the mechanical effort required to move air through the restricted bronchial passages.

Choice C rationale

An asthma cough is typically non-productive (dry) or, if secretions are present, it is often a mucoid, tenacious sputum. A consistently productive cough suggests other underlying conditions, such as infection (e.g., pneumonia) or bronchiectasis, rather than being the hallmark of a primary, mild-to-moderate asthma flare.

Choice D rationale

Wheezing, a high-pitched whistling sound, is the classic objective sign of asthma, caused by the vibration of air attempting to move rapidly through the severely narrowed, obstructed small airways (bronchioles) during respiration. It is often most prominent on expiration but can be present on inspiration during a significant episode.

Choice E rationale

Prolonged expiration occurs because the narrowed, inflamed airways obstruct the outflow of air, leading to air trapping and a higher residual volume. The patient must forcefully and slowly push air out against the resistance, making the expiratory phase last significantly longer than the inspiratory phase, a key sign of obstructive lung disease.

Choice A rationale

Epiglottitis is a rapidly progressive, life-threatening bacterial infection causing severe swelling of the epiglottis, potentially leading to acute, complete upper airway obstruction. The most critical initial nursing action is to minimize distress and be immediately prepared for definitive airway management (intubation or tracheostomy) by the appropriate team, as the airway can close suddenly.

Choice B rationale

Racemic epinephrine is an α-adrenergic agonist used to cause vasoconstriction and reduce subglottic edema, primarily indicated for croup. Epiglottitis involves supraglottic swelling, and while it may theoretically reduce edema, the primary risk is mechanical obstruction, making preparation for airway management the priority.

Choice C rationale

While prompt intravenous antibiotic administration is essential to treat the causative bacterium, usually Haemophilus influenzae type b, this action is secondary to securing a patent airway. A patient can die from asphyxiation much faster than from bacteremia, thus airway security must be addressed first.

Choice D rationale

Attempting to obtain a throat culture in a child with suspected epiglottitis is contraindicated. Any manipulation of the posterior pharynx or epiglottis, such as using a tongue blade or swab, can trigger laryngospasm and cause immediate, complete airway obstruction, which is a catastrophic complication.
