A nurse is reinforcing teaching with the parent of a school-age child who has ADHD and a new prescription for a methylphenidate transdermal patch. Which of the following statements by the parent indicates an understanding of the teaching?

Choice A reason: The correct answer is choice A. The nurse should expect the presence of the Moro reflex in a 6-month-old infant. The Moro reflex is a normal primitive reflex seen in infants up to about 6 months of age. When the infant experiences a sudden loss of support or a loud noise, they react by extending their arms and legs and then pulling them back in, as if trying to grasp onto something. This reflex is an important indicator of the baby's neurological development.

Choice B reason:

The birth weight doubling by 6 months of age is a typical growth milestone for infants. However, this statement is not correct in the context of the question, as it is not something the nurse should "expect” during a well-child visit. Instead, it is a general developmental milestone that healthcare providers monitor over time.

Choice C reason:

The correct answer is choice C. The nurse should expect the posterior fontanel to be closed in a 6-month-old infant. Fontanels are soft spots on a baby's skull that allow for brain growth during early development. The posterior fontanel, located at the back of the head, is typically closed by 6 months of age.

Choice D reason:

The correct answer is choice D. At 6 months of age, many infants can sit unsupported. However, not all infants achieve this milestone at the exact same age. Some may achieve it a bit earlier, while others might take a little more time. It is essential for the nurse to assess the infant's developmental progress and provide appropriate guidance to the parents.

Choice E:

The correct answer is choice E. By 6 months of age, some infants may be able to move from their back to their front. This is usually accomplished through rolling over. However, like other developmental milestones, the age at which infants achieve this can vary. Therefore, while the nurse may expect this ability in some infants, it is not something that all 6-month- old infants will have mastered at the time of the well-child visit.

Choice A reason:

The nurse should not initiate contact precautions for a child with suspected epiglottitis. Epiglottitis is primarily caused by Haemophilus influenzae type B, and it spreads through respiratory droplets. Contact precautions are not necessary as the transmission occurs through droplets, and standard precautions should be sufficient.

Choice B reason:

The nurse should monitor pulse oximetry. Epiglottitis is a condition where the epiglottis becomes inflamed and swollen, potentially blocking the airway. Monitoring the child's pulse oximetry helps assess their oxygen saturation levels, which is crucial in determining if there is adequate oxygenation. If the oxygen saturation drops significantly, immediate intervention might be needed to maintain the child's airway and prevent hypoxia.

Choice C reason:

Obtaining a throat culture is not an appropriate intervention for suspected epiglottitis. In cases of suspected epiglottitis, the priority is to ensure the child's airway is maintained and that they receive appropriate medical attention promptly. Throat culture collection involves swabbing the throat to identify the infectious agent and is not a priority in this urgent situation.

Choice D reason:

Administering epinephrine IM is not indicated for suspected epiglottitis. Epinephrine is typically used to treat severe allergic reactions (anaphylaxis) and not for managing epiglottitis. The primary focus in epiglottitis is securing the airway and providing appropriate medical treatment, which might include antibiotics and respiratory support.
