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: This is not a correct instruction for the nurse to include in the teaching. The Pavlik harness is a device that holds the infant's hips in a flexed and abducted position to allow the femoral head to fit into the acetabulum. The harness should not be removed by the parents, as this may interfere with the treatment and cause complications. The nurse should instruct the parents to sponge bathe the infant while wearing the harness.

Choice B reason: This is not a correct instruction for the nurse to include in the teaching. The length of the straps of the Pavlik harness should not be adjusted by the parents, as this may affect the alignment and stability of the infant's hips. The nurse should instruct the parents to bring the infant to the provider's office regularly for check-ups and adjustments of the harness.

Choice C reason: This is not a correct instruction for the nurse to include in the teaching. Massaging the infant's skin under the straps of the Pavlik harness may cause irritation, friction, or pressure on the skin, which may lead to skin breakdown or infection. The nurse should instruct the parents to keep the infant's skin clean and dry, and to check for any signs of redness, swelling, or drainage.

Choice D reason: This is a correct instruction for the nurse to include in the teaching. Placing the diaper under the straps of the Pavlik harness prevents the diaper from interfering with the position and function of the harness. The nurse should instruct the parents to change the diaper frequently and to avoid using bulky or cloth diapers.

Choice A reason: Your baby will receive a hepatitis B vaccine prior to discharge is correct, as this is the recommended schedule for the first dose of the hepatitis B vaccine for all newborns, regardless of maternal hepatitis B status.

Choice B reason: Your baby will have the first diphtheria, tetanus, pertussis vaccine at the 2 week well-baby visit is incorrect, as this is too early for the first dose of the DTaP vaccine. The first dose of the DTaP vaccine should be given at 2 months of age.

Choice C reason: Your baby should receive the pneumococcal conjugate vaccine on his first birthday is incorrect, as this is too late for the first dose of the PCV13 vaccine. The first dose of the PCV13 vaccine should be given at 2 months of age, followed by three more doses at 4, 6, and 12-15 months of age.

Choice D reason: Your baby should receive the measles, mumps, rubella vaccine at 6 months is incorrect, as this is too early for the first dose of the MMR vaccine. The first dose of the MMR vaccine should be given at 12-15 months of age, followed by a second dose at 4-6 years of age.
