What is secondary hemostasis? Ans: ✓ ✓ ✓ Activation of clotting factors, fibrin mesh, stable clot
Which test monitors heparin therapy? Ans: ✓ ✓ ✓ aPTT(activated partial thromboplastintime)
Which test monitors warfarin therapy? Ans: ✓ ✓ ✓ PT( (partial thrombin time)/INR
What labs are in a BMP(Basic metabolic panel)? Ans: ✓ ✓ ✓ Na, K, Cl, CO2, BUN, Creatinine(CR),
Glucose

Liver Function Tests, Albumin, Calcium

Which immune system response is fast but nonspecific? Ans: ✓ ✓ ✓ Innate immunity (neutrophils,
macrophages)
Which immune cells provide long-term memory and specific response? Ans: ✓ ✓ ✓ Lymphocytes
(B cells and T cells).
What is the function of red blood cells? Ans: ✓ ✓ ✓ Transport oxygen, carry CO■, maintain acid-
base balance
What is the function of white blood cells? Ans: ✓ ✓ ✓ Defend against infection and foreign
substances.
What is Hemostasis? Ans: ✓ ✓ ✓ Hemostasis is the process of preventing blood loss from intact
vessels and of stopping bleeding from a severed vessel, which requires adequate numbers of
functional platelets. Platelets nurture the endothelium and thereby maintain the structural integrity
of the vessel wall. Two processes are involved in arresting bleeding: primary and secondary
hemostasis
Primary hemostasis vs secondary hemostasis Ans: ✓ ✓ ✓ In primary hemostasis, the severed
blood vessel constricts. Circulating platelets aggregate at the site and adhere to the vessel and to
one another. An unstable hemostatic plug is formed. For the coagulation process to be correctly
activated, circulating inactive coagulation factors must be converted to active forms. This process
occurs on the surface of the aggregated platelets at the site of vessel injury.
Primary hemostasis involves the formation of a platelet plug at the site of injury, while secondary
hemostasis involves the coagulation cascade and the formation of a fibrin clot to stabilize the initial
plug.
Blood is _% plasma and _% cells Ans: ✓ ✓ ✓ 55% plasma
40-45% cells
Erythrocytes
Leukocytes
Thrombocytes Ans: ✓ ✓ ✓ Erythrocytes -red blood cells
Leukocytes-white blood cells
