What should a nurse monitor for in a child diagnosed with a coarctation of the aorta?

Monitoring for pulse discrepancies between extremities is crucial in a child diagnosed with coarctation of the aorta. This condition involves a narrowing of the aorta, which can lead to differential blood flow. When the aorta is constricted, it can significantly affect blood pressure and pulse strength in the arms compared to the legs. Typically, children with this condition may have stronger pulses and higher blood pressures in the upper body (arms) and weaker or absent pulses and lower blood pressures in the lower body (legs). Identifying these discrepancies can be pivotal in assessing the severity of the condition and monitoring for potential complications, such as hypertension in the upper body and decreased circulation to the lower extremities.

The other options do not directly relate to the primary concerns or manifestations of coarctation of the aorta. Hypoglycemia isn't a typical consideration in this context, while fever spikes may occur for various reasons but don't specifically indicate complications related to the aorta's condition. An increased appetite is not typically associated either, making pulse discrepancies the most relevant and important monitoring focus.
