and extracellular K+
In hyperkalemia what change occurs to the cells resting membrane
potential?
A) hypopolarization
B) hyperexcitability
C) depolarization

,Physiologic pH is maintained around 7.4 because carbonic acid (H2CO3)
and bicarbonate (HCO3) exist in a ratio of:
A) 20:1
B) 1:20
C) 10:2
D) 10:5 - ANSWERS-Ans: A- 20:1
Increased capillary hydrostatic pressure results in edema because of:
A) losses or diminished production of plasma albumin
B) inflammation resulting from an immune response
C) blockage within the lymphatic channel system
D) sodium and water retention - ANSWERS-Ans: C- blockage within the
lymphatic channel system
Hyopmethylation and the resulting effect on oncogenes result in:
A) a decrease in the activity fo the oncogene, thuse suppressing cancer
development
B) deactivation of MLH1 to halt deoxyribonucleic acid (DNA) repair
C) an incrase in tumor progression from benign to malignant
D) overexpression of micro-ribonucleic acid (miRNA), resulting in
tumorigenesis - ANSWERS-Ans: C- an increase in tumor progression from
benign to malignant
, During cell injury caused by hypoxia, sodium and water move into the cell
because:
A) during cell injury cause by hypoxia, sodium and water move into the cell
because:
B) the pump that transports sodium out of the cell cannot function because
of a decrease in adenosine triphosphate (ATP) levels
C) the osmotic pressure is increased, which pulls additional sodium across
the cell membrane
D) oxygen is not available to bind with sodium to maintain it outside of the
cell - ANSWERS-Ans: C- the osmotic pressure is increased, which pulls
additional sodium across the cell membrane
