●● What causes the edema that occurs during the inflammatory process?
Answer: Increased vascular permeability. Increased pressure in the
vasculature secondary to the vasodilatory effects of inflammation result
in leakage of fluid into 3rd spaces
●● Klinefelter syndrome
Answer: A chromosomal disorder in which males have an extra X
chromosome, making them XXY instead of XY.
High pitched voice
mental impairment
sparse body hair
small testes
gynecomastia
●● Alpha Thalassemia
Answer: Disease in which there are insufficient alpha-globin chains due
to gene deletions causing a reduction in hemoglobin. Future offspring
have 1/4 chance of disease.
,●● Blood flow of the heart
Answer: -Oxygen poor blood enter right atrium and flows into right
ventricle via vena cava
-Blood is pumped from right ventricle into pulmonary artery (goes into
lungs)
-Oxygen rich blood returns to heart via pulmonary vein and enters left
atrium and flows into left ventricle
-Blood is pumped into the aorta and circulated to body
●● What happens during diastole?
Answer: the heart is relaxed, semilunar valves are closed and blood from
atria fills ventricles; low pressure.
●● What happens during systole?
Answer: Heart muscles contract, creating pressure to open the
pulmonary and aortic valves.
Blood from R ventricle is pushed into the lungs to exchange O2 and
CO2.
Blood from the L ventricle is pushed thru the aorta to be distributed
throughout the body.
●● QRS complex
Answer: ventricular depolarization and atrial repolarization
,●● What effect does atherosclerosis have on the development of an
aneurysm?
Answer: Erodes the vessel wall. Plaque formation makes vessel rigid
and susceptible to rupture.
●● low-density lipoprotein (LDL)
Answer: blood fat that transports cholesterol to organs and tissues;
excess amounts result in the accumulation of fatty deposits on artery
walls.
<100
●● Which factor is responsible for hypertrophy of the myocardium
associated with HTN?
Answer: Angiotensin II
Stimulates increased cardiac preload and afterload leading to
hypertrophy, poor myocardial compliance, and ventricular dilation.
Causes sarcomere death, abnormal collagen matrices, and interstitial
fibrosis.
●● What gland produces Antidiuretic hormone?
Answer: posterior pituitary gland
●● T3 and T4 are regulated by
Answer: TSH
, ●● What causes SIADH?
Answer: Too much ADH.
Increased intravascular volume, decreased urine production, electrolyte
disturbance.
CNS - stroke, hemorrhage, infection, trauma
Medications - narcotics, oxytocin, chlorpropamide, antiepileptic agents
Trauma - pain is a powerful stimulus for ADH. What for post op pts who
is receiving fluids
Lung - simple pneumonia or ADH secreting small cell cancer of the
lung.
●● Hypothyroidism
Answer: High TSH, low T3 and T4
●● During the body's inflammatory process, what causes edema?
-Vasodilation of blood vessels
-Emigration of neutrophils
-Endothelial cell expansion
-Increased capillary permeability
Answer: Increased capillary permeability
