Ch 9 and Ch 10 (Lymphatic, Head, Neck) Flashcards
What are the 7 parts of the lymphatic system?
fluid, collecting ducts, lymph nodes, spleen, thymus, tonsils, adenoids, and peyer patches.
Can you find parts of the lymphatic system in the stomach, appendix, bone marrow and lungs?
yes
if (blank) is failing the patient may suffer from allergies, immune deficiency, or autoimmune diseases
lympathic system
The only tissues in the body that do not have lymphatic vessels are the (blank) and (blank)
brain and placenta
Fluid balance, production of lymphocytes, production of antibodies, phagocytosis of other cells/foreign bodies, backup of normal hematopoietic cells and (blank)
absorption of fat soluble substances from the GI tract
What color is lymph?
clear to yellow
What has cellular components mostly made of WBC’s “lymphocytes” with possible RBC’?.
lymph fluid
The microscopic ducts eventually coalesce and drain into the venous system at the (blank)
subclavian veins.
The lympathic system relies on the (blank) for flow
cardiovascular system
What are these:
Encapsulated structures that usually occur in groups. Superficial nodes are in the subcutaneous tissue. Deeper nodes exist in body cavities and under fascia and muscles. Most are smaller than 0.5 to 1cm.
lymph nodes
(blank) are a hint at the lymphatic system’s function via inspection/palpation for changes from baseline. Changes are mostly seen due to infection or malignancy.
superficial lymph nodes
(blank) cause an increase in lymphocyte counts.
Viral infections
Where is the spleen located?
left upper quadrant
The (blank) are activated by inhaled and intranasal antigens.
palatine tonsils
lymphatic system begins at (blank) gestation but is still immature at birth.
20 weeks
(blank) should always start a possible suspicion for malignancy.
Supraclavicular nodes
Palpable lymph nodes (inguinal, occipital, and postauricular nodes) after (blank) of age are more likely to be abnormal and indicate infection in children
2 years
Hep A, Hep B, Rubella, rubeola, and varicella, often present with obvious (blank)
Posterior cervical nodes
What makes for a suspicious node?
fast growing, immovable, painful, and large (2 cm) , should keep an eye out of bigger than .5cm
Is it a problem to have children with enlarged palantine tonsils?
no
Diphenylydantoin, aspirin, barbiturates, penicillin, tetracyclin, iodide, cephalosporin, sulfonamide, mesanoin can cause what>
nodal enlargement
What are the signs of mumps (epedmic parotiditis)?
painful swelling of parotid gland, and swelling of salivary glands on the mandible
How can you tell the difference between mumps and cervical adenitis?
cervical adenitis doesnt obscure the angle of the jaw and you can separate the node from the angle so you can feel the jaw.
(blank) is lymph tissue in the mucosa of the small intestine.
peyers patches
The umbilical cord should drop off by (blank) weeks after birth. If it hangs on longer->immune system defect
1-2
If cervical and submandibular nodes are present in the first year of life is this abnormal?
yes!
(blank) nodes should always start a possible susupicion for malignancy.
supraclavicular
Changes in pregnant women are due to (blank X 3)
progesterone, estrogen, and cortisol levels
In pregnant women what increases cells increase?
their leukocytes form 7200 to 8500 with largest increase in neutrophils and granulocytes
What type of immunity is increased in pregnant women?
humoral immunity (possibel decrease in autoimmune/inflammatory disease)
Who does this happen to?
Number and elements of lymph nodes are lost; the nodes may become fatty and fibrotic, leading to decreased ability to fight infection.
Older adults
What is pruritis?
itchy sensation
What is this for?
Character: onset, location, duration, number, tenderness
Associated local symptoms: pain, redness, warmth, red streaks
Associated systemic symptoms: malaise, fever, weight loss, night sweats, abdominal pain or fullness itching “pruritis”
Predisposing factors: infection, surgery, trauma
Medications: chemotherapy, antibiotics
Swelling of Extremity
Unilateral or bilateral, intermittent or constant
Predisposing factors: cardiac or renal disorder, surgery, infection, trauma, venous insufficiency
Associated symptoms: warmth, redness or discoloration, ulceration
Efforts at treatment and their effect: support stockings, elevation
HPI of enlarged lymph nods
What is this for?
Chest radiographs; reason and results
Tuberculosis and other skin testing
Blood transfusions, use of blood products
Chronic illness: cardiac, renal, malignancy, HIV infection
Surgery: trauma to regional lymph nodes; organ transplant
Recurrent infections
Autoimmune disorder
Allergies
PMH for enlarged lymph nodes
What is this important for?
Malignancy, anemia, recent infectious diseases tuberculosis, immune disorders, hemophilia
FH for enlarged lymph nodes
What is this important for?
Travel (Asia, Africa, Western Pacific, India, Philippines), Recreational drugs (Especially injected), ETOH use, Sexual History (HIV risk factors.)
Personal/social history
What are these important for?
Recurrent infections: tonsillitis, adenoiditis, bacterial infections, oral candidiasis, and chronic diarrhea. Recent infections or trauma distal to nodes, poor growth/Failure to thrive, Loss of interest in playing/eating, immunization history, maternal HIV infection, hemophilia
For infants
What are these important for?
weeks of gestation, exposure to rubella or other infections, Pets in household (cat feces etc.)
Pregnant women
What is this important for?
Autoimmune disease, recent infection/trauma distal to affected L nodes, delayed healing.
Diseases involving the lymphatic system: Toxoplasmosis, Roseaola infantum (HHV-6), HSV 1 or 2, cat scratch disease, HIV/AIDS, Serum sickness, Latex allergy type IV dermatitis, Latex allergy type I reaction
Older Adults
What is tenderness indicative of?
inflammation
Are cancerous nodes large and tender?
just large, not tender
How and what should you palpate and inspect for when looking at lymph nodes?
Use the pads of your fingers to lightly palpate note the consistency, mobility, tenderness, size and warmth.
What is lymphadenopathy (adenopathy)?
enlarged lymph nodes
What is lymphadenitis?
inflamed and enlarged lymph nodes
