While the Nurse Is Assisting a Patient to Ambulate, the Patient

While the nurse is assisting a patient to ambulate, the patient suddenly says, "I'm dizzy. I can't stand up." As the patient begins to fall, the nurse should:

A) tell the patient, "Look up, take some deep breaths, and stand up straight. You can do it."
B) call for another nurse or aide to get a wheelchair to return the patient to her room via wheelchair.
C) step behind the patient, grasp her around the waist or chest, and slide her down his leg gently to the floor.
D) look for the nearest chair and assist the patient to it.
