A nurse is preparing to administer a vaccine to a 4-year-old child. Which of the following vaccines should the nurse administer?

Choice A reason: Maintaining the infant in the supine position is not an appropriate intervention, as it can increase the pressure on the myelomeningocele sac and cause further damage to the spinal cord. The nurse should position the infant prone or side-lying, with the head turned to one side and the hips flexed.

Choice B reason: Limiting visitors to immediate family members is not a necessary intervention, as the infant does not have an infectious condition that requires isolation. The nurse should encourage the parents and other family members to visit and bond with the infant, and provide emotional support and education.

Choice C reason: Initiating contact precautions is not a required intervention, as the infant does not have a contagious condition that poses a risk of transmission to others. The nurse should follow standard precautions, such as washing hands, wearing gloves, and disposing of contaminated materials properly.

Choice D reason: Providing a latex-free environment is an essential intervention, as the infant has a high risk of developing a latex allergy due to the frequent exposure to latex products during surgery and other procedures. The nurse should avoid using latex gloves, catheters, syringes, bandages, or other items that contain latex, and use alternative materials instead. The nurse should also label the infant's chart, crib, and door with a latex allergy alert.

Choice A reason: Offering the child clear liquids for the first 24 hours is not necessary, as the child can resume a normal diet after the procedure. Clear liquids are only recommended for the first few hours after the procedure to prevent nausea and vomiting.

Choice B reason: Assisting the child to take a tub bath for the first 3 days is not advised, as it can increase the risk of infection and bleeding at the catheter insertion site. The child should avoid tub baths, swimming, and soaking the site until it is completely healed, which may take up to a week.

Choice C reason: Giving the child acetaminophen for discomfort is appropriate, as it can relieve the pain and soreness at the catheter insertion site. The child should avoid aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs), as they can increase the risk of bleeding.

Choice D reason: Keeping the child home for 1 week is not required, as the child can resume normal activities within a few days after the procedure. The child should avoid strenuous activities, such as running, jumping, and biking, for at least 24 hours after the procedure.
