What classic sign would the nurse, auscultating breath sounds of a child hospitalized for an asthma attack, expect to find?
Expiratory Wheezing
Fine Crackles
Coarse rhonchi
Decreased breath sounds at the lung bases
The Correct Answer is A
A. Expiratory Wheezing: Expiratory wheezing is a classic sign of an asthma attack. It occurs due to narrowing and inflammation of the airways, which causes turbulent airflow during exhalation. Wheezing typically gets louder during expiration as the airways are more constricted during this phase of breathing.
B. Fine Crackles: Fine crackles are often heard in conditions like pneumonia or heart failure, where fluid is present in the lungs. They are not a hallmark of asthma.
C. Coarse Rhonchi: Coarse rhonchi are low-pitched sounds often associated with mucous secretions in the larger airways, but they are not the classic finding in asthma, where wheezing predominates.
D. Decreased Breath Sounds at the Lung Bases: Decreased breath sounds can indicate severe respiratory distress or a condition like pleural effusion or atelectasis. However, in asthma, breath sounds are usually more prominent during wheezing and are not typically decreased in the absence of complications.

A. Inhaled Glucocorticoid: Used for managing asthma or other respiratory conditions, not for cardiac function.
B. Beta Adrenergic Blocker: Reduces blood pressure and heart rate but is not the mechanism of Digoxin.
C. Cardiac Glycoside: Digoxin is used to improve myocardial contractility and slow the heart rate, which aligns with this classification.
D. Angiotensin Enzyme Inhibitor: Typically used to manage hypertension and heart failure by affecting the renin-angiotensin system.
Correct Answer is C
Explanation
A. Temporal: The temporal pulse is difficult to palpate accurately in infants, so it is not the most reliable site to assess the pulse.
B. Dorsalis pedis: The dorsalis pedis pulse is located in the foot and is not as reliable for infants, as it can be difficult to palpate, especially in younger infants.
C. Apical: The apical pulse is the most reliable site to assess pulse in infants, as it is easily accessible and is directly over the heart. This is the preferred site for infants under 2 years old.
D. Carotid: The carotid pulse is sometimes used in emergencies but is not the most reliable or common site for routine pulse checks in infants, as it can be difficult to assess in younger infants.
