Answer to Question 1

ANS: B
This child has an isotonic dehydration, in which fluids and solutes are lost in balanced proportions, as evidenced by the normal serum sodium level. The child needs an isotonic IV solution, which would be 0.9 normal saline. The 0.45 normal saline (half normal saline) is hypotonic, as is D5W, with or without potassium. The 3 normal saline is hypertonic.

Answer to Question 2

ANS: D
All items are appropriate to teach when a child has a UTI. However, E. coli infection stems from contamination with fecal material. The female child should be taught to wipe from front to back to prevent this cross-contamination.
