A nurse is reinforcing teaching about sibling adaptation with a parent of a child who has cystic fibrosis. Which of the following instructions should the nurse include in the teaching?

Choice A rationale:
This medication can cause ringing in the ears (Choice A) is not a common side effect of amoxicillin. Ringing in the ears (tinnitus) is not typically associated with the use of this antibiotic.
Choice B rationale:
This medication can cause muscle pain (Choice B) is not a common side effect of amoxicillin. Muscle pain is not among the usual adverse reactions associated with its use.
Choice C rationale:
This medication can cause loose stools (Choice C) is a relevant side effect of amoxicillin. Antibiotics, including amoxicillin, can disrupt the normal balance of gut bacteria, potentially leading to gastrointestinal disturbances such as diarrhea or loose stools.
Choice D rationale:
This medication can cause blurred vision (Choice D) is not a common side effect of amoxicillin. Blurred vision is not a typical adverse effect associated with the use of this antibiotic.

Choice A rationale:
Placing a toddler in a side-lying position on the affected side after administering otic medication is not recommended. This position can cause the medication to leak out, reducing its effectiveness, and can also increase the risk of infection. It's important to keep the medication in the ear canal for an adequate amount of time to allow it to work properly.
Choice B rationale:
Allowing the medication to reach room temperature prior to administration is not a critical step for otic medications. While warming certain medications can reduce discomfort, this is not a specific requirement for ear drops. Ensuring the cleanliness of the ear, proper positioning, and correct administration technique are more important.
Choice C rationale:
The correct choice. Sitting the child in an upright position is the recommended approach for administering otic medication. This position helps ensure that the medication remains in the ear canal and is not immediately expelled. It also facilitates better penetration of the medication into the ear canal, increasing its effectiveness.
Choice D rationale:
Gently pulling a child's ear upward is a technique used for administering otic medications to straighten the ear canal and allow better access to the medication. However, this step alone is not sufficient. Proper positioning of the child is equally important to prevent the medication from leaking out.
