A nurse is providing teaching to the parent of an infant who has gastroesophageal reflux. Which of the following statements by the parent indicates an understanding of the teaching?

D. A client's blood pressure changes from 112/60 mm Hg to 90/54 mm Hg when standing.
A significant drop in blood pressure when changing positions from lying to standing may indicate orthostatic hypotension, which can be a sign of dehydration, blood loss, or other underlying medical issues. This can be a cause for concern, especially if the client is an adolescent, as it may lead to decreased perfusion of vital organs and may require immediate medical attention.

The other options are as follows:
A. A client who has a burn injury to an estimated 5% of his leg and is crying - While it's essential to assess and address the client's pain and comfort, this finding does not indicate an immediate need for medical attention. Pain management and wound care can be addressed based on the severity of the burn and the client's pain level.
B. A client who has an ankle fracture reports a pain level increase from 3 to 5 after initial ambulation - This finding is concerning, and the nurse should notify the provider to reassess pain management and evaluate for potential complications related to the fracture. However, it may not require immediate medical attention unless there are signs of severe pain or complications.
C. A client who is 1 day postoperative and has a temperature of 37.5° C (99.5° F) - A slight increase in temperature in the immediate postoperative period may not be unusual and can be attributed to the normal inflammatory response after surgery. The nurse should continue monitoring the client's temperature and report any further changes or additional signs of infection or complications to the provider.
Overall, while all findings should be addressed and managed appropriately, the significant drop in blood pressure (option D) should be reported immediately due to the potential implications for the client's overall health and well-being.

In an infant with a history of vomiting and fever, body weight is the most reliable indicator of fluid loss. Monitoring the infant's weight over time can help assess the degree of dehydration and guide the appropriate fluid replacement therapy. A significant decrease in body weight suggests significant fluid loss.

Option A: Skin integrity is important to assess for signs of dehydration, but it is not as reliable as body weight in determining the extent of fluid loss.
Option B: Respiratory rate can be affected by various factors and is not a direct indicator of fluid loss.
Option D: Blood pressure is not the most reliable indicator of fluid loss in an infant with dehydration. In severe cases of dehydration, blood pressure can drop, but it is not as sensitive as body weight in assessing the extent of fluid loss.
