Neuromusculoskeletal System

The nurse assists the health care provider to perform a lumbar puncture. When pressure is placed on the jugular vein during a lumbar puncture, the spinal fluid pressure is expected to increase. Which sign should the nurse expect the health care provider to document?

ExplanationD. If there is no obstruction, pressure on the jugular vein causes increased intracranial pressure (Queckenstedt sign). This, in turn, causes an increase in spinal fluid pressure. A. Homan sign is calf pain possibly elicited by dorsiflexion of the foot if thrombophlebitis is present. B. Romberg sign is failure to maintain balance when the eyes are closed; it indicates cerebellar pathology. C. Chvostek sign is twitching elicited by tapping the angle of the jaw; it occurs if hypocalcemia is present.
