When caring for an older adult client, which new finding should prompt the nurse to call for assistance immediately?

Choice A reason: Rhinorrhea for several days may indicate infection or allergies, but it is not immediately life-threatening. Choice B reason: Salivary glands not being enlarged is a normal finding and does not require intervention. Choice C reason: Mild pain in bilateral knees is common in older adults due to arthritis or degenerative changes. It is not urgent. Choice D reason: Unilateral facial drooping is a critical finding because it may indicate a stroke or neurological emergency. Immediate assistance is required to prevent permanent damage and initiate timely treatment.
