1. What is the Lachman maneuver assessing for?
o A) Injury to wrist
o B) Injury to ACL
o C) Injury to ankle
o D) Injury to C-spine
Correct Answer: B) Injury to ACL
Rationale: The Lachman test is a specific physical exam
maneuver designed to assess the integrity of the anterior cruciate
ligament (ACL) in the knee by detecting anterior tibial translation.
2. What is the McMurray sign assessing for?
o A) Carpal tunnel
o B) Rotator cuff injury
o C) None of the above

o D) Injury to the meniscus
Correct Answer: D) Injury to the meniscus
Rationale: The McMurray test is a classic orthopedic exam used
to detect tears in the menisci of the knee by eliciting a click or
pain with rotation of the tibia on the femur.
3. How can pain from a meniscus injury present?
o A) Inability to sleep on back
o B) Inability to hop on two feet
o C) Inability to rotate wrist
o D) Immediate pain on affected planted leg and inability to bear
weight
Correct Answer: D) Immediate pain on affected planted leg
and inability to bear weight
Rationale: Acute meniscal tears often occur with a twisting injury
on a planted foot, leading to immediate, severe pain, swelling, and
mechanical symptoms like locking or catching, making weight-
bearing difficult.
4. What can happen with a meniscus injury when the leg is
attempted to be straightened?

NR 511
o A) It can make it feel better
o B) It will stay that way forever
o C) It can lock up
o D) None of the above
Correct Answer: C) It can lock up
Rationale: A classic symptom of a displaced meniscal tear (a
"bucket-handle" tear) is mechanical locking of the knee, where the
patient cannot fully extend the leg due to a fragment of torn
meniscus blocking joint movement.
5. How do you assess for a radial head fracture?
o A) Palpate for tenderness
o B) Palpate for crepitus just distal to the lateral epicondyle
o C) All of the above
o D) Palpate for swelling
Correct Answer: C) All of the above
Rationale: Assessment for a radial head fracture involves
examining for localized tenderness and swelling over the radial
head (lateral elbow), and crepitus with rotation. The "fat pad sign"
on lateral elbow x-ray is also indicative.

6. What is the difference between articular and non-articular
musculoskeletal complaints?
o A) Non-articular involves no focal tenderness
o B) Articular involves no focal tenderness
o C) Non-articular complaints involve a point or focal tenderness
o D) Articular involves a point or focal tenderness
Correct Answer: C) Non-articular complaints involve a point
or focal tenderness
Rationale: This is a bit tricky. Typically, articular (joint)
problems cause pain throughout the joint's range of motion. Non-
articular problems (like tendinitis, bursitis) often present with
very specific, focal tenderness at a discrete point, such as the
lateral epicondyle in tennis elbow. The phrasing here is key: non-
articular issues often have a specific "point" of tenderness.
7. What does the bulge test check for?
o A) Knee joint effusion
o B) Wrist joint pain
o C) Ankle effusion
