COMPLETE 100 QUEST, EXAMS OF NURSING
Homeostasis refers to maintaining a relatively stable internal environment. The "internal
environment" is:
a) the blood cells
b) body parts beneath the skin
c) the cytoplasm of all the cells in the body
d) plasma, interstitial fluid, and transcellular fluid
e) intracellular fluid - - ANS✔️--plasma, interstitial fluid, and transcellular fluid
Which of the following is an example of positive feedback?
a) Consuming caffeine increases urine output, causing dehydration
b) The arrival of platelets at a wound causes the release of clotting factors which cause more
platelets to arrive at the wound
,2|Page
c) When a person stands up, blood pressure decreases because of the blood pooling in the feet
and legs. As a result, the heart beats faster and blood vessels constrict in order to bring blood
pressure back to normal
d) both a) and b) are correct
e) both b) and c) are correct - - ANS✔️--The arrival of platelets at a wound causes the release of
clotting factors which cause more platelets to arrive at the wound
Following an increase in body temperature, which of the following responses will NOT occur?
a) an increase in skin blood flow
b) an increase in skin temperature
c) an increase in non-shivering thermogenesis
d) an increase in sweat production
e) an increase in evaporation of the skin - - ANS✔️--an increase in non-shivering thermogenesis
When pyrogens are present, vasodilation is used by the body to create a fever
a) True
b) False - - ANS✔️--True
Mice from a certain lab strain remain healthy as long as you feed them regularly and do not let
them exercise. After they eat, their blood glucose level rises slightly and then declines to a
,3|Page
homeostatic level. However if these mice fast or if they exercise at all, their blood glucose drops
dangerously. Which hypothesis best explains their problem?
a) The mice have insulin-dependent diabetes
b) the mice lack insulin receptors on their cells
c) the mice lack glucagon receptors on their cells
d) The mice can't synthesize glycogen from glucose - - ANS✔️--The mice lack glucagon
receptors on their cells
Liver cells produce glycogen in response to:
a) glucagon
b) insulin - - ANS✔️--insulin
One of insulin's mechanisms of action is to:
a) activate Na+/K+ pump
b) increase the activity of SGLT
c) increase the facilitated diffusion of glucose into certain cells in the body
d) increase the number of sodium-linked glucose transporters in the cell membrane
e) more than one of the above is correct - - ANS✔️--increase the facilitated diffusion of glucose
into certain cells in the body
, 4|Page
NADH is produced from each reaction described except one. Identify the EXCEPTION.
a) during "aerobic" glycolysis
b) during the electron transport chain
c) in the Krebs cycle
d) during the conversion of pyruvate to acetyl CoA
e) more than one answer applies - - ANS✔️--during the electron transport chain
Under low oxygen conditions, ____________ must unload its electrons to allow glycolysis to
continue its production of ATP:
a) FADH2
b) lactic acid
c) NAD+
d) pyruvate
e) NADH - - ANS✔️--NADH
Which of the following statements about anaerobic metabolism is FALSE?
a) oxygen is limited or absent
b) pyruvate moves into the mitochondrion but then accumulates there, since the Krebs cycle does
not occur
