HIM 141 Chapter 3 Exam with Complete
Solutions Graded A+
With proper therapy the prognosis for children with juvenile rheumatoid arthritis is -
Answer-generally good.
With proper therapy, children with all forms of arthritis will usually improve over time.
Indeed, the vast majority of children with arthritis grow up to lead normal lives without
significant physical limitations.
Transmission of human immunodeficiency virus (HIV) is possible - Answer-- before it
can be detected by laboratory tests.
- during the "window period."
( when both a and c occur. )
Transmission of HIV is possible during all stages of infection, even before it can be
detected by laboratory tests, which is called the "window period." Patients with positive
test results for HIV should be encouraged to inform their sexual partners since they may
be at high risk for contracting the disease.
An autoimmune condition in which erythrocytes (red blood cells, RBCs) are destroyed
by antibodies, causing the patient to experience fatigue, chills, fever, dyspnea, and
jaundice, is - Answer-autoimmune hemolytic anemia.
Injections of vitamin B12, which must be continued for life, are the primary treatment for
pernicious anemia. - Answer-true
Intrinsic factor must be present in the gastric mucosa for vitamin B12 absorption to
occur. Vitamin B12 is necessary for RBC formation, and a deficiency causes RBCs to
be deformed and reduced in number.
The group of diseases that occur when antibodies develop and begin to destroy the
body's own cells is - Answer-autoimmune diseases.
Tolerance to self-antigens is believed to commence during fetal life. - Answer-true
Tolerance to self-antigens is believed to commence during fetal life. As the body ages
and experiences various disease processes or environmental exposures, persons with
a variety of genetic risks can have changes in their immune system whereby the system
misidentifies body tissues and develops autoantibodies that result in self-destruction.
