Final answer:
Acute pain is characterized by interfering with sleep, being minimized with traditional pain medication, and being related to medical findings.
Step-by-step explanation:
Acute pain is characterized by the fact that it interferes with the patient's ability to sleep (option A), whereas chronic pain does not. Therefore, option A is the correct answer. This type of pain is also typically minimized with traditional pain medication (option B) and is related to a medical finding (unlike option C). Acute pain is temporary and lasts for a shorter duration, usually less than three months, making option D incorrect.
