A client is seen in the emergent care clinic for right wrist pain with a pattern of ecchymosis observed on the wrist. Which motion should the nurse instruct the client to perform to assess the wrist mobility?

Choice A Reason: Hyperextension and palmar flexion are correct. Hyperextension involves moving the wrist joint backward, testing its ability to extend beyond its neutral position. Palmar flexion involves moving the wrist joint forward, testing its ability to flex toward the palm. These movements collectively assess the range of motion of the wrist joint in both directions, which is essential for identifying any limitations or pain associated with certain movements. Since the client presents with right wrist pain and ecchymosis, assessing both hyperextension and palmar flexion can help determine if there's any injury or impairment affecting the wrist's mobility. Choice B Reason: Plantar flexion is incorrect. Plantar flexion refers to a movement of the foot and ankle, not the wrist. Therefore, instructing the client to perform plantar flexion would not assess the wrist's mobility and is not relevant to the presented scenario of right wrist pain with ecchymosis. Choice C Reason: Forearm pronation is incorrect. Forearm pronation involves rotating the forearm so that the palm faces downward. This movement primarily assesses the pronation and supination of the forearm, not the wrist's mobility. Since the client's symptoms are specific to the wrist, assessing forearm pronation would not directly evaluate the wrist's range of motion. Choice D Reason: Forearm supination is incorrect. Forearm supination involves rotating the forearm so that the palm faces upward. Similar to forearm pronation, this movement primarily assesses the forearm's mobility, not the wrist's mobility. Therefore, instructing the client to perform forearm supination would not be an appropriate method for assessing the wrist's range of motion in the context of right wrist pain with ecchymosis.
