Answer to Question 1
ANS: D
When providing oral hygiene to an unconscious patient, the nurse needs to protect him or her from choking and aspiration. Have two nurses provide care; one nurse does the actual cleaning, and the other caregiver removes secretions with suction equipment. The nurse can delegate nursing assistive personnel to participate. Some agencies use equipment that combines a mouth swab with the suction device. This device can be used safely by one nurse to provide oral care. Commercially made foam swabs are ineffective in removing plaque. Do not use lemon-glycerin sponges because they dry mucous membranes and erode tooth enamel. While cleansing the oral cavity, use a small oral airway or a padded tongue blade to hold the mouth open. Never use your fingers to hold the patient's mouth open. A human bite contains multiple pathogenic microorganisms.
Answer to Question 2
ANS: D
The oral cavity is the priority. Radiation to the head reduces salivary flow and lowers pH of saliva, leading to stomatitis and tooth decay, while chemotherapy drugs kill the normal cells lining the oral cavity, leading to ulcers and inflammation. While the feet, nail beds, and perineum are important, they are not as affected as the oral cavity with head or neck radiation and chemotherapy.
