NPTE Lymphedema UPDATED Exam
Questions and CORRECT Answers
What amount of interstitial fluid is collected by the Lymph system? - CORRECT
ANSWER - - Collects 10% to 20% of interstitial fluid
- Collection of > 20% indicates that the venous system is not functioning properly
What are the 3 classifications of Lymph vessels? - CORRECT ANSWER - 1. Superficial
2. Intermediate
3. Deep
What organs are associated with the Lymph system? - CORRECT ANSWER - 1. Spleen
2. Tonsils
3. Thymus gland
- The thymus gland of the lymphatic system makes and trains special white blood cells of the
immune system called "T cells"
4. Bone Marrow
What is the normative size of lymph nodes? - CORRECT ANSWER - - Normal: <1 cm,
soft, nontender, nonpalpable
- If >1 cm in size → referral needed
What are some notable types of lymph nodes? - CORRECT ANSWER - 1.
Supramandibular
2. Cervical
3. UE
- Supraclavicular, axillary, central, subscapular, pectoral, humeral, cubital
4. LE
, - Iliac, inguinal, politeal
5. Parasternal, Mesenteric
What is the flow of lymph circulation? - CORRECT ANSWER - 1. Lymph capillaries ->
lymphatic vessels -> large lymph ducts (right lymphatic duct -> thoracic duct) -> Left subclavian
vein
2. Right lymphatic duct: right UE, right head and neck, right upper trunk
- Right subclavian vein
3. Thoracic duct: everything else
- Left subclavian vein
How does lymph vessel contraction occur? - CORRECT ANSWER - - Autonomic and
sensory nerve stimulation
- Contraction of adjacent muscle
- Changes in pressure of abdominal and thoracic cavities with breathing
- Mechanical stimulation of dermal tissue
- Volume changes within individual lymph vessel
What is lymphatic load? - CORRECT ANSWER - - Amount of lymphatic fluid that
NEEDS to be transported
What is Transport Capacity as it pertains to the lymph system? - CORRECT ANSWER -
Amount of lymph fluid that CAN be transported
Imbalance between load and capacity yields pathology. - CORRECT ANSWER - Yes.
What imbalance occurs during Venous insufficiency? - CORRECT ANSWER - Increased
load beyond normal capacity, leading to lymphedema
