Costovertebral angle tenderness should be assessed whenever the nurse suspects:

Choice A reason: Deep-vein thrombophlebitis involves deep vein inflammation and clotting, causing pain, swelling, and warmth, but not typically visible dilated veins. The described tortuous veins are superficial, not deep, making this an incorrect diagnosis for the findings.

Choice B reason: Varicose veins are dilated, tortuous superficial veins, often in the lower legs, causing heaviness or aching. These result from venous insufficiency, leading to blood pooling, which matches the patient’s visible veins and symptoms, making this correct.

Choice C reason: Peripheral artery disease causes reduced arterial blood flow, leading to pain, pallor, or claudication, not dilated veins. The visible tortuous veins suggest a venous issue, not arterial, making this an incorrect condition for the findings.

Choice D reason: Chronic lymphedema causes swelling due to lymphatic fluid accumulation, typically without dilated veins. The patient’s tortuous veins and heaviness point to venous pathology, not lymphatic, making this an incorrect diagnosis for the described symptoms.

Choice A reason: The Brief Pain Inventory relies on verbal or cognitive input, which is unreliable in advanced dementia due to impaired communication and cognition. Patients may not articulate pain, making this tool ineffective for assessing pain in this population.

Choice B reason: Observing body language, like pacing or agitation, is a valid pain indicator in advanced dementia. These nonverbal behaviors reflect discomfort processed by intact pain pathways, despite cognitive decline, making this a reliable assessment method.

Choice C reason: Noting vocalizations like groaning or crying is effective, as these are instinctive responses to pain, even in advanced dementia. These behaviors bypass cognitive deficits, reflecting pain perception in the brain’s nociceptive pathways, making this a correct choice.

Choice D reason: Assessing breathing changes, like rapid or irregular patterns, is a reliable nonverbal pain indicator in dementia. Pain can stimulate the autonomic nervous system, altering respiration independently of vocalization, making this a valid assessment technique.

Choice E reason: A 1-to-10 pain scale requires cognitive ability to quantify and communicate pain, which is impaired in advanced dementia. This method is unreliable, as patients cannot reliably report, making it an incorrect choice for this population.
