A
Feedback:
If a nurse taps the client's facial nerve (which lies under the tissue in front of the ear), the client's mouth twitches and the jaw tightens. The response is identified as a positive Chvostek's sign. A positive Trousseau's sign is elicited by placing a BP cuff on the upper arm, inflating it between the systolic and diastolic BP, and waiting 3 minutes. The nurse observes the client for spasm of the hand (carpopedal spasm), which is evidenced by the hand flexing inward. Positive Babinski's sign is elicited by stroking the sole of the foot. Paresthesia is not a symptom that can be elicited; it is felt by the client.
