A nurse is assessing a young child and suspects coarctation of the aorta based on which finding?
Diastolic murmur.
Hypotension.
Excessive crying.
Unequal upper and lower extremity pulses.
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 D
Explanation
Choice A rationale
While some children may pull their ears when they have a cold, it is not a definitive sign of acute nasopharyngitis. Ear pulling can also indicate other issues such as ear infections.
Choice B rationale
Antibiotics are not typically prescribed for acute nasopharyngitis, as it is usually caused by a viral infection. Antibiotics are only used if there is a secondary bacterial infection.
Choice C rationale
Healthy children can have multiple colds per year, especially if they are exposed to other children in settings like daycare or school. It is not uncommon for children to have several colds annually.
Choice D rationale
A cough that accompanies a cold should not be suppressed as it helps clear mucus from the airways. Suppressing the cough can lead to mucus buildup and potential complications.
Correct Answer is D
Explanation
Choice A rationale
Explaining the difference between right and wrong is a developmental task expected of older children, typically preschoolers or early school-aged children. Toddlers are still developing their understanding of rules and consequences.
Choice B rationale
Printing letters and numbers is a skill expected of preschoolers or early school-aged children. Toddlers are still developing fine motor skills and are not yet capable of printing letters and numbers.
Choice C rationale
Cooperating in doing simple chores is a developmental task that can be expected of toddlers. However, it is not as specific or significant as the ability to separate easily from the primary caregiver for short periods of time, which is a key developmental milestone for toddlers.
Choice D rationale
Separating easily from the primary caregiver for short periods of time is an important developmental milestone for toddlers. It indicates that the child is developing a sense of independence and trust in their environment, which is crucial for their social and emotional development.
