,I. Achilles Tendon & Posterior Ankle
Questions 1-13
1. Achilles tendon rupture is likely to occur in this position
A. Sprinters
B. Marathon runners
C. Skiers
D. Pediatric patients
Correct Answer: A. Sprinters
Rationale: The source directly identifies this finding as “Sprinters.” This is the source-paired
answer for the stem.
2. Gastroc-soleal complex is enervated by:
A. Deltoid branch
B. Tibial nerve (S1-S2)
C. L4, L5, S1
D. Posterior tibial artery
Correct Answer: B. Tibial nerve (S1-S2)
Rationale: The source directly identifies this finding as “Tibial nerve (S1 S2).” This is the source-
paired answer for the stem.
3. Runs between the gastrocnemius and soleus. Assists in plantarflexion of the foot and
flexion of the knee
A. FDL and tibialis posterior
B. FHL
C. Plantaris
D. Achilles tendon
Correct Answer: C. Plantaris
Rationale: The source directly identifies this finding as “Plantaris.” This is the source-paired
answer for the stem.
4. Nerve enervation of the plantaris
A. Tibial nerve (S1-S2)
B. Posterior tibial artery
C. Deltoid branch
D. L4, L5, S1
Correct Answer: D. L4, L5, S1
Rationale: The source directly identifies this finding as “L4, L5, S1.” This is the source-paired
answer for the stem.

, 5. The narrowest part of the Achilles tendon
A. 4 cm proximal to insertion
B. 2-6 cm proximal to attachment (watershed area)
C. 10 cm proximal to calcaneal insertion
D. 4-5 cm above the joint line
Correct Answer: A. 4 cm proximal to insertion
Rationale: The source directly identifies this finding as “4cm proximal to its insertion.” This is the
source-paired answer for the stem.
6. An Achilles tendon rupture is likely to occur what anatomical location?
A. 4-5 cm above the joint line
B. 2-6 cm proximal to attachment (watershed area)
C. 4 cm proximal to insertion
D. 10 cm proximal to calcaneal insertion
Correct Answer: B. 2-6 cm proximal to attachment (watershed area)
Rationale: The source pairs this scenario with the following key point: 2-6cm proximal to
attachment (watershed area) of the left lower extremity (due to handedness: Right handed
individuals more commonly push off with the left foot).
7. Name the Test: squeezing of the calf muscle does not result in plantar flexion of the
foot
A. Fluorescein Test
B. Hawkins' sign
C. Thompson Test
D. O'Brien Test
Correct Answer: C. Thompson Test
Rationale: The source directly identifies this finding as “Thompson Test.” This is the source-paired
answer for the stem.
8. Name the Test: A 25 gauge needle is inserted a right angle to the leg through the skin of
the calf muscle just medial to midline. This should be performed 10 cm proximal to the
calcaneal insertion of the Achilles tendon. Motion of the hub of the needle in a direction
opposite that of the tendon during passive dorsiflexion and plantarflexion of the foot
confirms an intact tendon distal to the level of needle insertion.
A. Thompson Test
B. Fluorescein Test
C. Hawkins' sign
D. O'Brien Test
Correct Answer: D. O'Brien Test
Rationale: The source directly identifies this finding as “O'Brien Test.” This is the source-paired
answer for the stem.
