A nurse is preparing a child for a lumbar puncture. In which of the following positions should the child be placed for the procedure?

A. Placing the child in a protected environment for 48 hours is not a necessary measure for managing pertussis. Pertussis is transmitted through respiratory droplets, and standard precautions are typically sufficient.

B. Administering the pertussis vaccine is a preventive measure, but it is not a treatment for an active infection. In this case, the child already has pertussis, so administering the vaccine will not address the current illness.

C. Restricting oral fluids to 500 mL per day is not a recommended intervention for pertussis. Maintaining hydration is important, and fluid intake should be based on the child's needs.

D. This is the correct action. Reporting the diagnosis of pertussis to the public health department is a crucial step in preventing the spread of the disease. It allows for contact tracing and appropriate public health measures to be implemented to limit further
transmission.

A. Toddlers with phenylketonuria (PKU) need to limit their intake of phenylalanine, an amino acid found in protein. Therefore, the toddler's protein consumption should be carefully controlled and monitored.

B. Foods high in iron do not need to be specifically limited for a child with PKU. Iron-rich foods are important for overall health and should be included in the diet.

C. Aspartame contains phenylalanine and should be avoided by individuals with PKU. PKU is a metabolic disorder that impairs the body's ability to break down phenylalanine, so it is important to limit phenylalanine intake.

D. This is correct. Foods containing milk products should be avoided, as they are a source of phenylalanine and can contribute to an excessive intake of this amino acid in a child with PKU. Instead, specialized medical foods low in phenylalanine are recommended.
