Answer to Question 1
C
Impacted cerumen can be removed by a physician or by a registered nurse under the direction of a physician. Most commonly, the external canal is irrigated using a syringe, or the older person is instructed to use an eardrop to soften the cerumen to facilitate its removal. Occlusion of the ear canal with cerumen can cause hearing difficulties; however, these hearing problems resolve after the cerumen is removed. Responses B and D are unnecessary. Response A is incorrect. The use of cotton-tipped applicators to clean the ear canal may increase the older person's hearing difficulties by pushing the cerumen deeper into the ear canal.
Answer to Question 2
C
