Q

It measures the rate at which the red blood cells (RBCs), or erythrocytes, in a sample of whole blood, fall to the bottom of the Westergren tube. This process of “falling” is called sedimentation.

16
Q

It is the initial analgesic of choice for patients with osteoarthritis.

A

Acetaminophen (paracetamol)

17
Q

It reduces friction between articulating cartilage surfaces, which serves as a protector against friction-induced cartilage wear.

A

Synovial fluid

18
Q

The lubrication function of synovial fluid depends on two factors.

A

hyaluronic acid, lubricin

19
Q

It develops when a minor joint injury occurs in the presence of posterior column peripheral neuropathy.

A

Charcot arthropathy

20
Q

Inflammatory cytokines that induce chondrocytes to synthesize prostaglandin E2 and nitric oxide which have complex effects on matrix synthesis and degradation.

A

interleukin 1-beta, tumor necrosis factor alpha

21
Q

To minimize the risk of nonsteroidal-related GI side effects, patients should ____________.

A

take NSAIDs after food, gastroprotective agent

22
Q

The only conventional NSAID that appears safe from cardiovascular perspective but have GI toxicity.

A

Naproxen

23
Q

These are secreted by the synovium which activate the chondrocytes to produce enzymes which accelerate destruction of matrix in osteoarthritis.

a. inflammatory cytokines
b. alarmins
c. fibroblasts
d. two of the options are correct
e. all of the options

A

D. inflammatory cytokines and alarmins

24
Q

(TRUE or FALSE) Stiffness in OA of the affected joint may be prominent, but morning stiffness usually lasts for >30min.

A

FALSE. <30min (brief)

25
Q

It is also called a degenerative joint disease which is characterized by cartilage degeneration that results in structural and functional failure of synovial joints.

A

Osteoarthritis

26
Q

It is the principal pathogenic mechanism of osteoarthritis.

a. genetic factors
b. age
c. biomechanical stress
d. obesity

A

C

27
Q

These are mushroom-shaped bony outgrowths which develop at the margins of the articular surface and are capped by fibrocartilage and hyaline cartilage that gradually ossify.

A

Osteophytes

28
Q

(TRUE or FALSE) Joint deformities develop over time in OA leading to fusion.

A

FALSE

29
Q

It is characterized by erythema, warmth, and tenderness on palpation of the bursa, and possibly decreased range-of-motion in certain planes secondary to discomfort.

A

Bursitis

30
Q

These are considered red flags of musculoskeletal disorders and are Acute, Focal, and Monoarticular, except:

a. Gout
b. Septic arthritis
c. Fibromyalgia
d. Vascular ischemia
e. Carpal tunnel syndrome

A

C. it should be fracture

MNEMONICS: GradSchoolFVCk

31
Q

What makes aspirin unique from other NSAIDs?

a. Reduces the risk of GI toxicity
b. Reduces fever
c. Irreversibly inhibits its target enzyme
d. Selectively inhibits the COX-2 enzyme

A

C

32
Q

Acetaminophen is an analgesic and antipyretic drug which lacks __________ action.

A

anti-inflammatory

33
Q

It is a nonselective COX inhibitor NSAID which have shown to interfere with the antiplatelet effects of aspirin.

A

Ibuprofen

34
Q

It is a non–purine xanthine oxidase inhibitor which prevents hyperuricemia and should not be given to patients on azathioprine or mercaptopurine as plasma levels of these drugs will rise.

A

Febuxostat

35
Q

I has been widely used for treatment of knee OA, with the rationale to reduce joint inflammation and pain by the local delivery of a potent anti-inflammatory agent.

A

intra-articular corticosteroids
