Differential lab test correct answer: - total up to 100
- contains (segmented) neutrophils make up 60%-70%,
lymphocytes, Monocytes 3%-7%
Monocytes correct answer: -When they leave the circulation
and enter tissue, they mature into macrophages, which are found
in large quantities in the spleen and other organs.
-Their primary function is phagocytosis
Neutrophils correct answer: immature=bands/ number comes
out separate from the total neutrophils if infection or
inflammatory process is present
mature=segmented
-They are first responders to an infection, stressful event, or
inflammatory reaction.
-Antigens, epinephrine, and corticosteroids stimulate generation
and release of neutrophils in the bloodstream.
-Mature neutrophils = also called polymorphonuclear leukocytes

Basophils correct answer: Basophils are generated and released by the bone marrow in response to many inflammatory reactions, particularly parasitic infection. Leukocytosis correct answer: - white blood cells are elevated, above 11,

  • average white count for an adult is 5k-10k Leukemoid reaction correct answer: is a white blood count of more than 50,000.
  • will just be written as 50 implying 50k. What is reverse isolation? correct answer: - Protect the patient from you.
  • cover entire body so nothing infectious is in contact with the patient.
  • room cannot contain flowers, plants and raw food. Leukopenia correct answer: -A decrease in WBC count below 4,000/uL is leukopenia, which is a general term that describes a decrease in all types of WBCs. -Leukopenia increases the risk of infection, and diminishes healing ability.

breathing fast, BP might be on the lower side, HR is high.

  • bp and hr are opposing. Erythropoiesis correct answer: - makes red blood cells
  • epogen increases red blood cells. when you want to know how well your patient is able to make rbc's where do you look? correct answer: RETIC COUNT.
  • separate test concerning the persons hemoglobin and hematocrit and ability to make new cells.
  • higher the number the more the person is doing a good job at making rbc's. What stimulates bone marrow to synthesize RBC's? correct answer: Erythropoietin What stimulates the kidney to release erythropoietin? correct answer: Hypoxia Healthy RBCs include.. correct answer: Nutrition is key. protein, iron, vitamin B12, and folic acid. Iron is the main nutritional element needed for hemoglobin synthesis. Breakdown of HemoGlobin correct answer: - in the breakdown process if heme is getting spit out into the tissues at a rapid rate patient will turn yellow (jaundice)
  • bilirubin accumulates in the bloodstream, a condition called hyperbililirubinemia
  • two occasions you may see this:
  1. newborn can turn yellow treated with phototherapy and fluids. if not treated bilirubin can stain the brain
  2. liver failure from any cause Splenomegaly correct answer: - enlarged spleen
  • if you feel the spleen thats abnormal ABO Blood Types correct answer: -There are two different types of agglutinogens: type A and type B. -The ABO blood type classification system categorizes blood into four types according to these agglutinogens: type A, B, AB, and O ABO incompatibility correct answer: - when mother and baby have different blood types.

  • most moms are RH positive but If mom is Rh negative she needs to be administered rogam

  • but If trying to stimulate production number then normal reticulocyte count is more than 1%

Thrombocytosis correct answer: is the term for an excessive number of platelets, greater than 750,000/uL, which can cause excessive clotting Hemostasis correct answer: stops the bleeding..
