Answer to Question 1

To determine whether the patient can hear clearly using the hearing aid, turn your back to the patient and ask a question slowly and clearly in a normal tone of voice. Depending on your position, the patient may be able to read your lips. The prostheses are limited by the function of the ear structures. The hearing aid may not be the problem in this case.
Answer to Question 2
C
Alopecia is balding patches in the periphery of the hairline. Offer patients access to scarves, hairpieces, or wigs. Stop hair care practices that damage hair. Shaving hair off of the affected area is the treatment for pediculosis pubis (crab lice). Permethrin is the treatment for pediculosis capitis (head lice). Ticks are removed by placing a drop of oil or ether on the tick, causing it to suffocate.
