Question 1
The most cost-effective screening test for determining HIV status is
which of the following?
A) Western blot
B) Polymerase chain reaction (PCR)
C) Enzyme-linked immunosorbent assay (ELISA)
D) CD4 count
Answer: C) Enzyme-linked immunosorbent assay (ELISA)
Rationale: ELISA is the most cost-effective screening test for HIV. It is
highly sensitive, relatively inexpensive, and widely available. Positive ELISA
results must be confirmed with a Western blot or other confirmatory test.
PCR is more expensive and used for viral load monitoring or early
detection. CD4 count assesses disease progression, not diagnosis.
Question 2
Which blood test is a nonspecific method and most helpful for
evaluating the severity and course of an inflammatory process?
A) Erythrocyte sedimentation rate (ESR)
B) C-reactive protein (CRP)
C) White blood cell count
D) Rheumatoid factor
Answer: B) C-reactive protein (CRP)
Rationale: CRP is a nonspecific acute-phase reactant that rises rapidly in
response to inflammation. It is more sensitive and responds more quickly
,than ESR to changes in inflammatory status, making it particularly useful for
monitoring disease activity and treatment response.
Question 3
Cocaine acts as a stimulant by blocking the reuptake of which
neurotransmitter?
A) Serotonin
B) Norepinephrine
C) Dopamine
D) Acetylcholine
Answer: C) Dopamine
Rationale: Cocaine's primary mechanism of action is blocking the reuptake
of dopamine at the synaptic cleft, leading to increased dopamine
concentrations in the brain's reward centers. This produces euphoria and
reinforcing effects. Cocaine also affects norepinephrine and serotonin
reuptake but to a lesser extent.
Question 4
Mrs. Thomas was seen in the office complaining of pain and point
tenderness in the area of her elbow. The pain has increased following
a day of gardening one week ago. A physical finding that
differentiates the diagnosis and is most consistent with lateral
epicondylitis (tennis elbow) is:
A) Pain with passive wrist flexion
B) Pain at the elbow with resisted movements at the wrist and forearm
C) Numbness in the fourth and fifth fingers
D) Decreased range of motion at the elbow joint
Answer: B) Pain at the elbow with resisted movements at the wrist and
forearm
Rationale: Lateral epicondylitis is characterized by pain over the lateral
epicondyle that worsens with resisted wrist extension and supination. The
, pain is reproduced when the patient resists the clinician's attempt to
extend the wrist or supinate the forearm. This finding helps differentiate it
from other elbow pathologies.
Question 5
Which of the following statements concerning the musculoskeletal
examination is true?
A) The involved side should be examined initially and then compared to the
uninvolved side
B) The uninvolved side should be examined initially and then compared to
the involved side
C) Both sides should be examined simultaneously
D) Only the involved side needs to be examined
Answer: B) The uninvolved side should be examined initially and then
compared to the involved side
Rationale: Examining the uninvolved (asymptomatic) side first establishes
a baseline for normal anatomy, range of motion, and strength. This
approach prevents the patient from anticipating painful maneuvers and
allows for more accurate comparison with the affected side.
Question 6
Which of the following signs or symptoms indicate an inflammatory
etiology to musculoskeletal pain?
A) Pain that worsens with activity
B) Morning stiffness
C) Pain that improves with rest
D) Localized tenderness
Answer: B) Morning stiffness
Rationale: Morning stiffness lasting longer than 30-60 minutes is a
hallmark of inflammatory joint disease (e.g., rheumatoid arthritis).
