3 stages of hemostasis
1. vascular constriction
2. formation of platelet plug
3. blood coagulation
Bleeding associated with platelet disorders reflects: decrease
in platelet number because of:
1. decreased production (bone marrow dysfunction)
2. increased destruction (thrombocytopenia)
3. impaired function of platelets (thrombocytopathia)
Spontaneous bleeding from platelet disorders often involve small
vessels of mucus membranes and skin:
mucus membranes of nose, mouth, GI tract, and uterine cavity
petechiae is seen exclusively with conditions of platelet
deficiency
**not platelet dysfunction thrombocytopenia
Platelet < 150,000 can
result from:
1. decrease in platelet production
2. increased sequestration of platelets in spleen
3. decreased platelet survival

4. Inadequate RBC production because of bone marrow failure characteristics of RBC
in iron deficiency anemia microcytic and hypochromic characteristics of RBC in
megablastic anemai macrocytic and misshaped characteristics of RBC in sickle
cell disease abnormally shaped blood loss anemia is characterized by loss of iron
containing blood cells in body hemolytic anemia is characterized by
destruction of RBC in the body with iron being retained Reason
for iron deficiency anemia (IDA) in adults inadequate iron
available for recycling:
-men/postmenopausal women: GI bleed from peptic ulcer, vascular lesions, intestinal
polyps, hemorrhoids, or cancer -women childbearing age: menstruation
-pregnant women: fetal development increases iron requirements for erythropoiesis
Reason for IDA in children blood volume increases with greater need for iron
(proportionally higher in infancy between 3-24 months):
low iron levels at birth because of maternal deficiency and a diet consisting mainly of
cow's milk (low in absorbable iron)
Clinical Course of Infectious Mononucleosis
-onset is insidious
-incubation period (from exposure to the development of symptoms) 4-6 weeks -
prodromal period (early stage/symptom presentation) lasts for several days and
characterized by malaise, anorexia, and chills--> precedes onset of fever, pharyngitis,
and lymphadenopathy
-acute phase lasts 2-3 weeks with recovery occurring rapidly
-debility and lethargy may persist for 2-3 months most
common complication of infectious mononucleosis
splenomegaly (50-60% cases) spleen enlarged 2-3 times
normal size rupture is rare; educate to avoid contact sports
diagnosing infectious mononucleosis monospot testing
for heterophile antibodies (hallmark)

IgM and IgG increased early in disease
Manifestations of Hodgkin's Lymphoma
-painless enlargement of single node or group of nodes (typically at level of diaphragm:
neck, supraclavicular, axilla)
-mediastinal mass (c/o chest discomfort with cough or dyspnea)
-fever, chills, night sweats, and weight loss
-pruritus and intermittent night fevers
Diagnosis of Hodgkin's Lymphoma
Reed-Sternberg cells present in biopsy of lymph tissue
-bipedal lymphangiogram detects structural changes of lymph nodes too small to see on
CT
-bilateral bone marrow biopsy performed on patient's suspected of disseminated
diseases
Treatment of Hodgkin's Lymphoma
localized disease is treated with radiation
advanced disease may use combined approach of radiation, chemotherapy, and
biotherapy
Definition of preload aka ventricular filling; considered the end-diastolic pressure when
the ventricle has been filled
represents the volume work of the heart; work or load imposed on the heart before
contraction begins & represents the amount of blood the heart must pump with every
beat
Conditions that increase preload
cardiogenic shock mitral or aortic
regurgitation bradycardia
