A school-age child with leukemia experienced severe nausea and vomiting when receiving chemotherapy for the first time. Which is the most appropriate nursing action to prevent or minimize these reactions with subsequent treatments?

A. Urine specific gravity 1.015 is correct. A specific gravity of 1.015 indicates good hydration status and that the child is effectively retaining fluids after oral rehydration therapy. Normal urine specific gravity ranges from 1.010 to 1.020.

B. Respiratory rate 24/min is not directly related to hydration status and does not necessarily indicate that rehydration therapy has been effective. It is a normal rate for a 3-year-old child, but respiratory rate alone isn't an indicator of fluid balance.

C. Heart rate 130/min is elevated for a 3-year-old child and may indicate dehydration or other stressors, suggesting that oral rehydration therapy has not been completely effective. A normal heart rate for this age is typically 80-120 beats per minute.

D. Capillary refill greater than 3 seconds is a sign of dehydration and poor perfusion, indicating that the oral rehydration therapy has not been effective in restoring hydration. Normal capillary refill time is less than 2 seconds.

A. Has your child had a fever? While fever can be associated with febrile seizures, it is not a question used to screen for epilepsy. Febrile seizures are typically isolated events in young children and are not considered part of chronic epilepsy.

B. Did your child have an aura prior to a seizure? This is an important question for assessing epilepsy, especially focal seizures, as many individuals with epilepsy experience an aura (a warning sign) before a seizure. The presence or absence of an aura helps in classifying the type of seizure and can be useful in diagnosis.

C. Has your child had two or more seizures, in the last 1 year? This is not a screening question for epilepsy, but it would be relevant if epilepsy has already been diagnosed. Two or more seizures within a year can indicate a seizure disorder, but asking if the child has had multiple seizures would be more appropriate once epilepsy is suspected.

D. How long did your child's seizure last? The duration of a seizure is important to note during an episode, but it is not a question used during initial screening. The nurse would focus more on whether seizures occur, how they manifest, and if there are any warning signs (like an aura) prior to the event.
