What does the student learn about erythrocytes? Select one.
Question options:
a) 20 to 30
b) 60 to 90
c) 200 to 240
d) 100 to 120
Hide question 1 feedback
Feedback
Because it cannot undergo mitotic division, the erythrocyte has a limited life span of up t
days.

Shortened erythrocyte life span, ineffective bone marrow response to
erythropoietin, and altered iron metabolism describe the pathophysiologic
characteristics of which type of anemia? Select one.
Question options:
a) Aplastic
b) Anemia of chronic disease
c) Iron deficiency
d) Sideroblastic
Hide question 2 feedback
Feedback
Anemia of chronic disease specifically results from a combination of (1) decreased erythr
suppressed production of erythropoietin, (3) ineffective bone marrow erythroid progenito
erythropoietin, and (4) altered iron metabolism and iron sequestration in macrophages.

The healthcare professional explains to a student that glucose 6-phosphate
dehydrogenase (G6PD) deficiency is what type of inherited disorder? Select
one.
Question options:
a) X-linked dominant
b) Autosomal dominant
c) X-linked recessive
d) Autosomal recessive
Hide question 3 feedback
Feedback
G6PD deficiency is an inherited, X-linked recessive disorder.

A patient is 8 hours postoperative after a long orthopedic procedure. The
student asks why this patient is at particular risk of developing a
thromboembolism. What response by the healthcare professional is best?
Select one.
Question options:
a) Endothelial damage occurs and repair is slowed by postoperative pain.
b) Atherosclerotic build up causes turbulent blood flow leading to clots.
c) Patients tend to have venous stasis from orthopedic operations.
d) Anesthetic agents often cause an immune response against clotting factors.
Hide question 4 feedback
Feedback
Thromboembolic events are caused by some component of Virchow triad: endothelial inju
flow, and hypercoagulability of the blood. Long operative procedures such as orthopedic
stasis. Anesthetic agents are not implicated. Endothelial repair is not appreciably hinder
pain. Atherosclerotic buildup can lead to endothelial injury but that is not specific to this

A hospitalized patient's lab work is as follows: WBC 2000, bands 14.8%, and
segmented neutrophils 5. The healthcare professional calculates the
patient's absolute neutrophil count (ANC). What action does the
professional take next? Select one.
Question options:
a) Implements protocols to prevent life-threatening infections
b) Encourages the patient to limit any visitors for the present time
c) Does nothing; this is a normal ANC for the white cell count
d) Holds the patient's medications until the ANC returns to normal
Hide question 5 feedback
Feedback
The ANC is calculated by multiplying the white blood cell count by the sum of the bands
neutrophils. This patient's ANC is 396, placing him or her at extremely high risk of devel
threatening infection. Visitors may need to be limited but that will not protect the patien
infection. The patient's medications would not all be held because of this finding.

A patient has been diagnosed with acute lymphocytic leukemia (ALL) and
asks the healthcare professional to describe it. What description by the
professional is most accurate? Select one.
Question options:

marrow or blood.
What does the student learn about erythrocytes? Select one.
