In which congenital heart defect would the nurse need to take upper and lower extremity blood pressures?
Aortic stenosis (AS)
Transposition of the Great Vessels (Arteries)
Coarctation of the Aorta (COA)
Tetralogy of Fallot (TOF)
The Correct Answer is C
A. Aortic stenosis (AS) typically causes a difference in blood flow across the aortic valve but does not usually require assessment of upper and lower extremity blood pressures.
B. Transposition of the Great Vessels (Arteries) results in cyanosis and abnormal circulatory flow but does not require upper and lower extremity blood pressure monitoring.
C. Coarctation of the Aorta (COA) is characterized by narrowing of the aorta, often resulting in higher blood pressure in the upper extremities compared to the lower extremities. Measuring both helps identify this condition.
D. Tetralogy of Fallot (TOF) involves right ventricular outflow obstruction, VSD, overriding aorta, and right ventricular hypertrophy, but upper and lower extremity blood pressures are not typically used for diagnosis.

C. Adenovirus can cause respiratory infections but is not the primary pathogen for bronchiolitis.
D. Rhinovirus causes the common cold but is not typically responsible for bronchiolitis.
Correct Answer is A
Explanation
A. The child is showing signs of severe respiratory distress, likely due to epiglottitis. The priority is to keep the child calm to avoid further airway obstruction and to prepare for emergency airway management.
B. While assessing the throat for epiglottitis is important, direct visualization of the throat can cause spasm and worsen airway obstruction.
C. The knee-to-chest position is typically used in cases of respiratory distress in infants (e.g., with RSV), but not in this case.
D. While IV access and fluids may be necessary, the immediate priority is securing the airway.
