The nurse is teaching a client about how to use crutches. Which action performed by the client demonstrates to the nurse a correct understanding of how to use the crutches?

Choice A reason: Reviewing the advanced directive document is not the priority action. The nurse should first intervene to clear the airway and prevent aspiration of vomitus.

Choice B reason: Elevating the head of the bed 45 degrees is a good practice, but it is not sufficient to relieve the choking. The nurse should also perform suctioning to remove the vomitus from the mouth and throat.

Choice C reason: Performing oropharyngeal suctioning is the best action as it helps to clear the airway and prevent aspiration of vomitus. The nurse should use a Yankauer suction catheter and apply intermittent suction while moving the catheter around the mouth and throat.

Choice D reason: Irrigating the nasogastric tube with water is not appropriate as it may worsen the vomiting and choking. The nurse should stop the enteral feeding and clamp the tube until the client's condition is stabilized.

Choice A reason: This is an incorrect action as it indicates poor posture and balance. The client should walk with the elbows slightly flexed and the shoulders relaxed.

Choice B reason: This is the correct action as it ensures proper fit and comfort of the crutch. The client should fit the crutch 2 finger widths from the axilla to prevent nerve damage and pressure ulcers.

Choice C reason: This is an incorrect action as it may cause pain and injury to the wrists and hands. The client should adjust the height of the hand grips to allow a 30-degree bend at the elbow.

Choice D reason: This is an incorrect action as it may cause instability and falls. The client should hold the crutch 4 to 6 inches (10 to 15 cm) in front and to the side of the foot.
