The patient was diagnosed with an injury to the ligaments and tendons of the right knee. Which terminology, documented by the nurse, best reflects the injury? {Ans: Sprain}A patient sustains a fracture of the arm. When does the nurse anticipate pendulum exercise should begin? {Ans: As soon as tolerated, after a reasonable period of immobilization Many impacted fractures of the surgical neck of the humerus are not displaced and do not require reduction. The arm is supported and immobilized by a sling and swathe that secure the supported arm to the trunk (Fig. 43-10). Limitation of motion and stiffness of the shoulder occur with disuse. Therefore, pendulum exercises begin as soon as tolerated by the patient. In pendulum or circumduction exercises, the physical therapist instructs the patient to lean forward and allow the affected arm to hang in abduction and rotate. These fractures require approximately 4 to 10 weeks to heal, and the patient should avoid vigorous arm activity for an additional 4 weeks. Residual stiffness, aching, and some limitation of ROM may persist for 6 months
