A nurse is assessing a young child and suspects coarctation of the aorta based on which finding?

A.

Diastolic murmur.

B.

Hypotension.

C.

Excessive crying.

D.

Unequal upper and lower extremity pulses.

Answer and Explanation

The Correct Answer is D

Choice A rationale

 

A diastolic murmur is not a typical finding in coarctation of the aorta. This condition is more commonly associated with systolic murmurs.

 

Choice B rationale

 

Hypotension is not a common finding in coarctation of the aorta. In fact, hypertension in the upper extremities is more typical due to the narrowing of the aorta.

 

Choice C rationale

 

Excessive crying is not a specific indicator of coarctation of the aorta. It can be a symptom of many different conditions and is not diagnostic.

 

Choice D rationale

 

Unequal upper and lower extremity pulses are a key finding in coarctation of the aorta. The narrowing of the aorta causes reduced blood flow to the lower extremities, resulting in weaker pulses compared to the upper extremities.

Correct Answer is B

Explanation

Choice A rationale

Turning the child’s head to the side and pressing on the nasal ridge is not the recommended method for managing nosebleeds. This position can cause blood to flow into the throat, leading to swallowing blood and potential vomiting.

Choice B rationale

Sitting the child upright and leaning slightly forward while applying pressure to the sides of the nose is the correct method. This position helps prevent blood from flowing into the throat and allows it to clot more effectively.

Choice C rationale

Having the child lie flat and apply pressure to the cheeks is not effective for stopping a nosebleed. This position can cause blood to flow into the throat, leading to swallowing blood and potential vomiting.

Choice D rationale

Putting the child in bed, elevating the head slightly, and pressing on the forehead is not effective for stopping a nosebleed. The pressure needs to be applied directly to the soft part of the nose to control the bleeding.
