A nurse in an emergency department is caring for an infant who has a 2-day history of vomiting and an elevated temperature. Which of the following should the nurse recognize as the most reliable indicator of fluid loss?
Blood pressure.
Respiratory rate.
Body weight.
Skin integrity.
The Correct Answer is C
Choice A rationale
Blood pressure is not the most reliable indicator of fluid loss in infants. Blood pressure can remain normal until dehydration is severe.
Choice B rationale
Respiratory rate can be affected by many factors and is not the most reliable indicator of fluid loss.
Choice C rationale
Body weight is the most reliable indicator of fluid loss in infants. A significant decrease in body weight indicates significant fluid loss and helps guide appropriate fluid replacement therapy.
Choice D rationale
Skin integrity can be affected by many factors and is not the most reliable indicator of fluid loss.

Correct Answer is C
Explanation
Choice A rationale
While discipline is an important aspect of parenting, the nurse’s response should focus on normalizing the child’s behavior and providing reassurance to the parent. Discussing discipline methods may not address the parent’s immediate concern about temper tantrums.
Choice B rationale
Suggesting that some children have more difficult personalities and recommending parenting books may not provide the immediate reassurance and understanding the parent needs. It is important to normalize the child’s behavior and explain that temper tantrums are a normal part of development.
Choice C rationale
Toddlers are beginning to develop a sense of autonomy and independence, which can lead to temper tantrums as they assert their desires and preferences. Explaining that temper tantrums are normal during this stage of development helps reassure the parent and provides a better understanding of their child’s behavior.
Choice D rationale
While diet can play a role in behavior, the nurse’s response should focus on normalizing the child’s behavior and providing reassurance. Discussing diet may not address the parent’s immediate concern about temper tantrums and difficult behaviors.
Correct Answer is D
Explanation
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.
