A nurse in a clinic is assessing a 9-month-old infant.
Which of the following findings requires further intervention?

The correct answer is Choice B.

Choice A rationale

Environment plays a significant role in a child’s growth and development, including factors like socioeconomic status, access to education, and living conditions. However, it can be altered to some extent.

Choice B rationale

Genetics is the largest factor impacting growth and development that cannot be altered. Genetic factors determine physical characteristics, susceptibility to certain diseases, and overall growth patterns.

Choice C rationale

Socialization influences a child’s development, including social skills and behavior. While important, it can be influenced and altered through various interventions.

Choice D rationale

Nutrition is crucial for growth and development, affecting physical and cognitive development. However, it can be modified through dietary changes and interventions.

The correct answer is Choice 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.
