The ACOLS Manual Lymphatic Drainage (MLD) Training Examination is the definitive certification assessment for
healthcare professionals seeking to practice Manual Lymphatic Drainage and Complete Decongestive Therapy.
Administered by the Academy of Lymphatic Studies (ACOLS)—the first school in the United States to establish
its curriculum based on the European Foeldi CDT system—this examination validates mastery of lymphatic
system anatomy, physiology, pathology, MLD techniques, compression therapy, and clinical decision-making for
lymphedema management. The ACOLS Complete Lymphedema Certification (CLC) is a rigorous 135-hour
program that includes 45 hours of online coursework and 9 days of hands-on practical training, culminating in
written and practical examinations that must be passed to earn the Certified Lymphedema Therapist (CLT)
credential. The examination is critical because certified lymphedema therapists are entrusted with managing
complex lymphatic disorders, and a single error in technique or clinical judgment can exacerbate a patient's
condition. This question bank has been meticulously crafted to simulate the advanced, application-level
difficulty of the actual ACOLS MLD Training Examination. By working through these 200 scenario-driven
questions covering lymphatic anatomy, MLD techniques, contraindications, compression therapy, and clinical
applications, you will develop the clinical reasoning and technical precision needed to pass on your first
attempt.
CORE DOMAINS TESTED
1. Lymphatic System Anatomy & Physiology – Lymphatic capillaries, pre-collectors, collectors, lymph
nodes, lymphatic trunks, ducts, watersheds, and lymph formation; superficial vs. deep lymphatic
systems.
2. Lymphatic Pathways & Drainage Territories – Cervical, axillary, inguinal, and popliteal lymph node
regions; lymphatic watersheds; and specific drainage territories for extremities, trunk, head, and neck.
3. Pathophysiology of Lymphedema & Edema – Primary vs. secondary lymphedema, Stages 0–III,
Starling's law, lymphatic load vs. safety valve capacity, and differential diagnosis of edema.
4. Manual Lymphatic Drainage (MLD) Techniques – Vodder technique, basic strokes (stationary circles,
pump technique, scoop technique, rotary technique), sequence of treatment, and hand placement.
5. Contraindications & Precautions – Absolute vs. relative contraindications for MLD, compression
therapy, and deep abdominal techniques; special populations.
6. Compression Therapy & Bandaging – Short-stretch bandages, multi-layer bandaging, compression
garments, measurement techniques, and contraindications for compression.
7. Complete Decongestive Therapy (CDT) Components – MLD, compression, decongestive exercises,
skin and nail care; phase I vs. phase II treatment.
8. Clinical Applications & Patient Assessment – Lymphedema measurement (circumference and
volumetric), patient education, home maintenance, and billing considerations.

QUESTIONS 1-200
Q1: A therapist is reviewing the structure of the lymphatic system with a
student. Which of the following best describes the primary purpose of the
lymphatic collectors?
A) To transfer interstitial fluid to the lymph capillaries
B) To connect the superficial and deep lymphatic systems
C) To transport lymph to lymph nodes and lymphatic trunks
D) To forward lymph directly to the liver for filtration
Rationale: The correct answer is C because collectors transport lymph from pre-
collectors to lymph nodes and lymphatic trunks. Option A is incorrect because
transferring interstitial fluid to lymph capillaries is the function of initial lymph
capillaries. Option B is incorrect because connecting superficial and deep
systems is a function of perforating vessels. Option D is incorrect because lymph
is not forwarded to the liver for filtration; it is filtered by lymph nodes.
Q2: A therapist is teaching a patient about the normal volume of lymph fluid
returned to the venous system daily. What is the correct volume?
A) 0.5–1 liter
B) 2–4 liters
C) 5–7 liters
D) 8–10 liters
Rationale: The correct answer is B because the lymphatic system returns
approximately 2–4 liters of lymph fluid to the venous system daily. Option A is
incorrect because 0.5–1 liter is too low. Option C is incorrect because 5–7 liters
exceeds normal volume. Option D is incorrect because 8–10 liters is far above
normal.
Q3: A therapist is performing MLD on a patient with lymphedema of the left
upper extremity. Where should the therapist begin the treatment sequence?
A) At the affected extremity to mobilize fluid
B) At the ipsilateral axillary lymph nodes
,3
C) At the contralateral axillary lymph nodes and trunk
D) At the cervical lymph nodes only
Rationale: The correct answer is C because MLD treatment always begins with
the contralateral, unaffected lymph node regions and trunk to clear central
drainage pathways before addressing the affected area. Option A is incorrect
because starting at the affected extremity would overwhelm blocked drainage
pathways. Option B is incorrect because the ipsilateral axillary nodes are the
affected region. Option D is incorrect because cervical nodes alone do not
provide adequate central clearance.
Q4: Which of the following is an absolute contraindication for Manual
Lymphatic Drainage?
A) Fibromyalgia
B) Acute deep vein thrombosis
C) Chronic venous insufficiency
D) Osteoarthritis
Rationale: The correct answer is B because acute DVT is an absolute
contraindication for MLD due to the risk of dislodging the thrombus and
causing pulmonary embolism. Option A is incorrect because fibromyalgia is not
an absolute contraindication. Option C is incorrect because chronic venous
insufficiency is a relative contraindication and may benefit from MLD with
precautions. Option D is incorrect because osteoarthritis is not a
contraindication.
Q5: A therapist is assessing a patient with swelling in the right lower extremity.
The patient has a history of coronary artery bypass grafting and is on
anticoagulants. Which of the following is the most appropriate action?
A) Proceed with MLD as normal
B) Avoid MLD entirely and refer to a physician
C) Perform MLD with reduced pressure and monitor for bleeding
D) Apply compression bandages only
, 4
Rationale: The correct answer is C because anticoagulant therapy is a relative
contraindication, and MLD may be performed with reduced pressure and
careful monitoring for signs of bleeding or bruising. Option A is incorrect
because normal pressure could increase bleeding risk. Option B is incorrect
because complete avoidance is not necessary. Option D is incorrect because
compression alone does not address lymphatic drainage.
Q6: A therapist is explaining the four main components of lymphatic load to a
patient. Which of the following is NOT a component?
A) Water
B) Proteins
C) Red blood cells
D) Long-chain fatty acids
Rationale: The correct answer is C because the lymphatic load consists of water,
proteins, cells/cell fragments, and long-chain fatty acids—not intact red blood
cells. Option A is incorrect because water is a component. Option B is incorrect
because proteins are a component. Option D is incorrect because long-chain
fatty acids are a component.
Q7: A patient presents with Stage II lymphedema of the left arm. Which of the
following best describes this stage?
A) Reversible pitting edema that resolves with elevation
B) Pitting edema that does not resolve with elevation and may have fibrosis
C) Non-pitting edema with significant fibrosis and skin changes
D) Elephantiasis with severe skin changes and disability
Rationale: The correct answer is B because Stage II lymphedema is
characterized by pitting edema that does not resolve with elevation and may
begin to show signs of fibrosis. Option A is incorrect because reversible pitting
edema describes Stage 0 or latent lymphedema. Option C is incorrect because
non-pitting fibrosis describes Stage III. Option D is incorrect because
elephantiasis is the most severe form of Stage III.
