A nurse is caring for a 6-month-old infant who is postoperative following a myringotomy. Which of the following pain scales should the nurse use to determine the infant's pain level?

Choice A: This response is appropriate, as it informs the parent that reporting suspected child abuse is a legal and ethical obligation for nurses, regardless of their personal opinions or feelings. This response also shows respect and honesty by acknowledging the parent's concern and explaining the reason for the nurse's action.

Choice B: This response is not appropriate, as it deflects responsibility and avoids answering the parent's question. This response also shows disrespect and dishonesty by implying that the provider is more qualified or authorized to explain the situation than the nurse.

Choice C: This response is not appropriate, as it denies information and creates confusion for the parent. This response also shows indifference and avoidance by suggesting that the nurse does not want to deal with the issue or communicate with the parent.

Choice D: This response is not appropriate, as it shifts blame and undermines trust between the nurse and the parent. This response also shows defensiveness and insecurity by implying that the nurse did not make the decision or take accountability for their action.

Choice A: A popping sensation when swallowing is not a sign of a tympanic membrane rupture, as it is a normal phenomenon that occurs when the eustachian tube opens and closes to equalize the pressure between the middle ear and the atmosphere. A popping sensation when swallowing may be associated with otitis media with effusion, which is a condition that causes fluid accumulation behind the eardrum, but it does not indicate a rupture.

Choice B: Green-blue discharge could be indicative of infection but is not as directly related to the rupture event as the sudden pain relief is.

Choice C: The correct answer is sudden relief of pain. This is because the rupture of the tympanic membrane releases the pressure and fluid that has built up in the middle ear, leading to an immediate decrease in pain.

Choice D: An increased temperature is not a sign of a tympanic membrane rupture, as it is a nonspecific symptom that may indicate various conditions, such as inflammation, infection, or fever. An increased temperature may be associated with otitis media with effusion, which is a condition that causes fluid accumulation behind the eardrum, but it does not indicate a rupture.
