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.

Correct Answer is A
Explanation
A. Both parents are carriers of the CF gene: Cystic fibrosis follows an autosomal recessive inheritance pattern, meaning both parents must carry one copy of the defective gene, even if they do not have the disease themselves. The child inherits one copy of the defective gene from each parent to develop CF.
B. The inheritance pattern is multifactorial: CF is not a multifactorial disease; it follows a clear recessive genetic inheritance pattern.
C. The result is probably a genetic mutation: CF is caused by a genetic mutation, but this mutation is inherited from both parents. It is not usually a spontaneous mutation unless it occurs in the parental genetic material, which is rare.
D. Only one parent carries the CF gene: For the child to inherit CF, both parents must be carriers of the gene. If only one parent carries the gene, the child would be a carrier, not affected by the disease.
Correct Answer is A
Explanation
A. Squatting increases the return of venous blood flow to the heart: Squatting increases systemic vascular resistance and venous return, which helps to increase oxygenation in children with Tetralogy of Fallot, as it reduces the right-to-left shunting and increases blood flow to the lungs.
B. Squatting in common resting position when a child is tachycardic: While squatting can be used to manage symptoms, this answer is misleading as squatting specifically helps in increasing blood flow and decreasing the symptoms of cyanosis in Tetralogy of Fallot, not just during tachycardia.
C. Squatting decreases arterial blood flow away from the heart: Squatting actually increases blood flow to the heart and lungs by increasing systemic vascular resistance.
D. Squatting increases the workload of the heart: Squatting helps reduce the workload on the heart in Tetralogy of Fallot by improving oxygenation and decreasing cyanosis.
