A nurse is teaching the parent of a toddler who has phenylketonuria about meal planning.
Which of the following information should the nurse include in the teaching?
Use aspartame as sugar substitute
Avoid foods containing milk products
Increase the toddlers protein consumption
Limit foods high in iron
The Correct Answer is B
Choice A rationale
Aspartame is a low-calorie sweetener used in place of sugar. However, it is not recommended for individuals with phenylketonuria (PKU) because it contains phenylalanine, an amino acid that individuals with PKU cannot metabolize properly.
Choice B rationale
Individuals with PKU are advised to avoid foods containing milk products. This is because milk and other
dairy products contain phenylalanine, which individuals with PKU cannot metabolize properly. Instead, they are advised to consume a diet low in protein and supplemented with a phenylalanine-free medical formula.
Choice C rationale
Increasing protein consumption is not recommended for individuals with PKU. This is because protein-rich foods often contain phenylalanine, an amino acid that individuals with PKU cannot metabolize properly.
Instead, they are advised to consume a diet low in protein and supplemented with a phenylalanine-free medical formula.
Choice D rationale
Limiting foods high in iron is not specifically related to the dietary management of PKU. Individuals with PKU primarily need to avoid foods high in phenylalanine.

Correct Answer is A
Explanation
Giving water after administering digoxin helps ensure that the medication is swallowed and reaches the stomach, which is important for proper absorption.
Correct Answer is C
Explanation
Choice A rationale
Washing the site with alcohol prior to applying the cream is not recommended. Alcohol can cause skin irritation and dryness, which may increase the discomfort during the procedure.
Choice B rationale
Rubbing the cream into the skin is not advised. The cream should be applied in a thick layer and not spread on the skin. Rubbing the cream can cause it to absorb into the skin too quickly and reduce its numbing effect.
Choice C rationale
Applying the cream 1 hour before the procedure is the correct action. Lidocaine and prilocaine cream should be applied at least 1 hour before the procedure to ensure adequate numbing of the skin.
Choice D rationale
The cream should not be left on the skin during the procedure. The healthcare provider will remove the cream just before the procedure. Leaving the cream on the skin could interfere with the procedure.
