Answer to Question 1

2
Rationale: Sunken anterior fontanel is symptomatic of dehydration, and the nurse would assess the child's skin turgor, weight, urine output, and intake for further evidence of abnormalities. Craniosynostosis is premature closure of the fontanels, and sunken fontanels do not indicate increased risk for developmental delays or neglect.

Answer to Question 2

2
Rationale: Excessive use of antacids can result in elevated magnesium levels (hypermagnesemia). The client's sodium, chloride, and potassium levels are all within normal limits, which would be unlikely if the hypermagnesemia were caused by renal failure.
