The nurse is caring for a child with cystic fibrosis. What is the rationale for the nurse performing chest physiotherapy for this child?
To monitor and assess the patient's lung function and oxygen saturation.
To provide pain relief and reduce inflammation in the lungs.
To improve lung function and remove mucus from the airways.
To administer medications directly into the lungs for targeted treatment.
The Correct Answer is C
A. Monitoring lung function and oxygen saturation is important but not the primary purpose of chest physiotherapy.
B. Chest physiotherapy does not primarily focus on pain relief or reducing inflammation; instead, it targets mucus clearance.
C. Chest physiotherapy is primarily performed to enhance lung function by mobilizing and clearing thick mucus from the airways, which is critical in managing cystic fibrosis and preventing infections.
D. While medications can be administered via nebulization, chest physiotherapy itself is not used for direct medication delivery but rather for airway clearance.

C. The test does not confirm immunity but rather measures antibodies against streptolysin O, indicating recent infection.
D. An elevated ASO titer confirms that the child had a recent streptococcal infection, which is important in diagnosing rheumatic fever.
Correct Answer is B
Explanation
A. Tricuspid atresia typically leads to decreased pulmonary blood flow due to the absence of normal blood flow to the lungs.
B. Patent ductus arteriosus results in increased pulmonary blood flow because it allows blood to flow from the aorta to the pulmonary artery, increasing the volume of blood going to the lungs.
C. Coarctation of the aorta can cause decreased blood flow to the lower body, which may not directly relate to increased pulmonary blood flow.
D. Tetralogy of Fallot is characterized by decreased pulmonary blood flow due to right ventricular outflow obstruction, making it not associated with increased pulmonary blood flow.
