Two Patients Are Hospitalized with the Same Diagnosis, but One

Two patients are hospitalized with the same diagnosis, but one is 23 years old, with acute recent pain from an injury, and the other is 64 years old, with pain of long-standing duration of several years.What is the difference in the anticipated assessments?

A) Acute pain for young patients is more intense at the same level, but these patients experience few changes in vital signs.
B) Young patients with acute pain exhibit fewer changes in vital signs but still report true levels of pain at levels 8 to 10.
C) Older adult patients with chronic pain exhibit increased changes in vital signs and report levels of pain lower than reality.
D) Older adult patients with chronic pain usually report lower levels of pain much less severe than they really are.
