Quiz Score: 116 out of 120
IncorrectQuestion 1
pts
Which hepatitis virus is known to be sexually transmitted?
A
B
C
D
Only hepatitis B virus (HBV) is known to be sexually transmitted.
IncorrectQuestion 2
pts
Which term is used to identify the movement of gas and air into and out of the lungs?
Perfusion
Ventilation
Respiration
Diffusion
,Of the options available, ventilation is the only term used to identify the mechanical movement
of gas or air into and out of the lungs.
Question 3
pts
Between which months of age does sudden infant death syndrome (SIDS) most often occur?
0 and 1
2 and 4
5 and 6
6 and 7
The incidence of SIDS is low during the first month of life but sharply increases in the second
month of life, peaking at 2 to 4 months and is unusual after 6 months of age.
Question 4
pts
Erythrocyte life span of less than 120 days, ineffective bone marrow response to erythropoietin,
and altered iron metabolism describe the pathophysiologic characteristics of which type of
anemia?
Aplastic
Sideroblastic
Anemia of chronic disease
,Iron deficiency
Anemia of chronic disease results from a combination of (1) decreased erythrocyte life span, (2)
suppressed production of erythropoietin, (3) ineffective bone marrow erythroid progenitor
response to erythropoietin, and (4) altered iron metabolism and iron sequestration in
macrophages. This result is not true of the other options.
Question 5
pts
How is most carbon dioxide (CO2) in the blood transported?
Attached to oxygen
In the form of bicarbonate
Combined with albumin
Dissolved in the plasma
Approximately 60% of the CO2 in venous blood and 90% of the CO2 in arterial blood are carried
in the form of bicarbonate.
Question 6
pts
The glomerular filtration rate is directly related to which factor?
Perfusion pressure in the glomerular capillaries
Diffusion rate in the renal cortex
Diffusion rate in the renal medulla
, Glomerular active transport
The filtration of the plasma per unit of time is known as the glomerular filtration rate (GFR),
which is directly related to only the perfusion pressure in the glomerular capillaries.
Question 7
pts
Which blood cell type is elevated at birth but decreases to adult levels during the first year of
life?
Monocytes
Platelets
Neutrophils
Lymphocytes
Only monocyte counts are high in the first year of life and then decrease to adult levels.
Question 8
pts
Perceived stress elicits an emotional, anticipatory response that begins where?
Prefrontal cortex
Anterior pituitary
Limbic system
