- A 59-year- old woman has been told by her orthopedist that the preferred treatment for her debilitating pain in both knees is knee replacement surgery. She agrees to have the surgery in one month when she will have time for rehabilitation. In the interim, the physician prescribes a medication for pain relief and to reduce inflammation. The woman is otherwise healthy, takes no medication, and has no known drug allergies. The physician decides on a nonsteroidal anti- inflammatory drug that has a high affinity for cyclooxygenase-2 (COX-2) and no affinity for COX-1. Compared to other NSAIDs, this drug is less likely to cause:
- A 69-year-old male presents to your office complaining of pain in his neck that extends bilaterally over his shoulders. He also complains of an aching sensation in both of his arms and loss of fine motor control of his hands. This has been progressing over the past six months. He worked in construction and had multiple small neck injuries during college wrestling and football. His overall health is quite good. On X-rays studies of his cervical spine you would expect to find?

- A 54-year-old male construction worker has had low back pain for about two months. He has had previous episodes of low back pain.

He is embarrassed to report that he was incontinent of urine and stool this morning. You should plan on:
- A 25-year-old female medical student comes to your office asking for an MRI of her neck to confirm her suspicion that she has a herniated cervical disc. On exam, her triceps reflex is absent, and she has weakness of elbow extension and numbness on her long finger. You both expect the MRI to reveal a disc herniation at:
- A 57-year-old physician presents to his doctor complaining of neck pain that radiates down the lateral aspect of his right arm. He also complains of numbness in his right thumb with weakness on resisted thumb extension. You suspect a herniated disc compression which nerve root?

- A 35-year-old male presents to your office with complaints of back pain and some weakness in his left leg. It has been present for a few weeks and the back and leg pains have been increasing in intensity. You are concerned about a herniated lumbar disc.

- A 25-year-old medical student comes to your office asking for an MRI of her neck to confirm her suspicion that she has a cervical disc herniation. On exam, her triceps reflex is absent. She has weakness of elbow extension and numbness on her long finger. You expect the MRI to reveal a disc herniation at at which of the following levels?
- A patient sustained a cervical sprain/strain (somatic dysfunction) secondary to trauma. She complains of non radiating neck pain in absence of shoulder pain. Given this scenerio, which of the following signs/symptoms would more likely be present than any other?
- What is the treatment for pseudoaddiction?
- Which is the most specific of the urine drug tests?
- What are the 4 A's for pain management?
- Which of the following are side effects from chronic opioid use?
- A 42-year-old nurse presents to the office to see if OMM can be helpful for her long-standing foot pain. The patient had sustained her foot injury five years prior when a car ran over her foot while trying to cross the street. She sustained multiple fractures at that time and the injury healed subsequent to multiple surgeries. There is no back pain and no pain in the legs. She is currently on morphine 60mg every twelve hours. Physical examination reveals relatively normal lumbar range of motion, normal straight leg raise, and reveals normal muscle tone, strength and sensation throughout both lower extremities. The foot and ankle are painful to touch on the surface. There is decreased range of motion of the ankle with erythema and skin dystrophic/atrophic changes. Which of the following pain management approaches is indicated:
- A 40-year-old male presents with a one-week history of low back pain without radiation. The symptoms started after he was carrying some luggage. There is no tingling, numbness in the legs, nor any reported weakness. There is minimal spasm in the paravertebral muscles in the lumbo-sacral spine, straight leg raising test is negative and the neurological examination is normal. There are somatic dysfunctions in form of neutral dysfunctions L1-L5 NSleftRright. Which of the following statements is most appropriate?
- Which of the following is correct about the various pain types?
- A 64-year-old school superintendent with known rheumatoid arthritis presents to the office with a recurrent episode of significant hand and wrist pain after having been virtually pain-free for about eight months on DMARD therapy as closely monitored by her rheumatologist. She questions the doctor as to how it could be that she has these painful chronic-recurrent flare-ups alternating with pain-free periods, all the while it seems that the "arthritis is getting better" with the medications. What would be the best explanation, based on the article by D. Marcus: "Treatment of Nonmalignant Chronic Pain?"
- A 56-year-old female with a known history of seropositive rheumatoid arthritis maintained on etanercept injections presents complaining of right knee pain and swelling for two days. She has been in good health otherwise and denies fevers and chills. She reports stiffness in the right knee that lasts for longer than 1 hour. Her other joints are doing well. You perform an arthrocentesis and remove 30cc of clear fluid. You send the sample to the lab, and 24 hours later no organisms are seen. The patient follows up later that day.

One of this drug's early signs/symptoms of toxicity is:
