Questions with Correct Answers | latest
2025.Chamberlain college of Nursing
Asthma - answer-; Chronic disease due to bronchoconstriction and an excessive
inflammatory response in the bronchioles
What are 5 s/s of asthma - answer-; coughing
wheezing
shortness of breath
rapid breathing
chest tightness
Why does hepatosplenomegaly develop in right sided heart failure - answer-; the
large volume of blood flow through the liver and spleen causes these areas to be
engorged
why does peripheral edema occur in right sided heart failure - answer-; Increased
pressure forces fluid from the systemic capillaries into the peripheral tissues and
flood those areas
,High output failure - answer-; inability of the heart to pump sufficient amounts of
blood to meet the circulatory needs of the body despite normal blood volume and
cardiac contractility
causes of high output failure - answer-; Severe anemia
Nutritional deficiencies
Hyperthyroidism
Sepsis
Extreme febrile state
Process of high output failure - answer-; - impaired oxygen delivery of excessive
tissue oxygen demands cause tissue hypoxia
- catecholamines initiation increase HR and stroke volume
- increased cardiac output is produced but depletes cardiac muscle reserve
overtime and leads to low output failure over time
Troponin-Calcium Binding - answer-; Calcium binds to troponin on the thin
filament
sliding filament theory - answer-; theory that actin filaments slide toward each
other during muscle contraction, while the myosin filaments are still
Hematopoiesis - answer-; formation of blood cells
, Where does blood cell formation occur in a fetus - answer-; 3 weeks - yolk
week 8 - fetal liver and spleen
5th month - bone marrow
Blood cell formation in chidren 0-5 years old - answer-; red marrow of all bones to
make blood cells
blood cell formation in adults over 20 - answer-; red marrow in large bones
-illium, vertebrae, cranium, jaw, sternum, ribs, humerus, and femur
Erythropietin - answer-; Produce: Kidney (small amount in liver)
Released: Kidney
Target: Bone Marrow
Functions: Stimulates bone marrow to produce more red blood cells
hematopoietic stem cells - answer-; The stem cells that give rise to RBC WBC and
platelets through the process of haematopoiesis.
How does a hematopoietic stem cell produce a red blood cell - answer-;
hematopoietic stem cells produces an unndifferentiated hemocytoblast
- erythropoietin binds to it and createsa a proerythroblast
- cell develops into an erythrocyte 7 days later
