Answer to Question 1

B
Three-point gait requires the patient to bear all of the weight on one foot. In a three-point gait, the patient puts weight on both crutches and then on the uninvolved leg. A two-point gait requires at least partial weight bearing on each foot. A four-point gait gives stability to the patient but requires weight bearing on both legs. The tripod position is the basic crutch stance.

Answer to Question 2

D
Turgor is the skin's elasticity. To assess skin turgor, grasp a fold of skin on the back of the forearm or sternal area with the fingertips and release. Normally the skin lifts easily and snaps back immediately to its resting position. The skin stays pinched or tented when turgor is poor. You can see pallor (unusual paleness) more easily in the face, buccal mucosa (mouth), conjunctivae, and nail beds. Localized skin changes, such as pallor or erythema (red discoloration), often indicate circulatory changes or are caused by localized vasodilation resulting from sunburn or fever. Observe for cyanosis (bluish discoloration) in the lips, nail beds, palpebral conjunctivae, and palms.
