What is accurate health promotion teaching to prevent ear infection or trauma? (Select all that apply)
Correct Answer: D
Rationale: The correct health promotion teachings to prevent ear infection or trauma include blowing the nose gently without blocking nostrils, wearing hearing protection when exposed to loud noise, and avoiding the use of cotton-tipped applicators to clean the external ear. Blocking one nostril when blowing the nose is incorrect, as it can cause problems. Therefore, choice A is inaccurate. Additionally, using cotton-tipped applicators to clean the external ear can lead to trauma or infection, making choice C a correct preventive measure.
