A healthcare professional is teaching a patient about Raynaud
phenomenon and instructs the patient to avoid cold. What is the
best explanation of how cold impacts the manifestations of this
disease?
Immune complexes that are deposited in capillary beds, blocking
circulation
Mast cells that are bound to specific endothelial receptors, causing
them to degranulate and creating a localized inflammatory reaction
that occludes capillary circulation
Cytotoxic T cells that attack and destroy the capillaries so that they
are unable to perfuse local tissues
2 | P a g e
Antibodies that detect the capillaries as foreign protein and destroy
them using lysosomal enzymes and toxic oxygen species -
ANSWER-ANS: A
Raynaud phenomenon is a condition (type III hypersensitivity
reaction) caused by the temperature-dependent deposition of
immune complexes in the capillary beds of the peripheral
circulation. The healthcare professional should teach the
patient to avoid cold or to wear gloves to mitigate the cold.
None of the other options are involved in causing this
condition.
Deficiencies in which element can produce depression of both Band T-cell function?
Iron
Zinc
Iodine
Magnesium - ANSWER-ANS: B
Of the options available, only deficient zinc intake can
profoundly depress T- and B-cell function.
3 | P a g e
An Rh-negative woman gave birth to an Rh-positive baby. When
discussing Rho[D] immunoglobulin with her, what information
should the healthcare professional provide?
It provides protection against infection from poor immunity in the
baby.
It prevents alloimmunity and hemolytic anemia of the newborn.
It provides necessary antibodies in case the mother doesn't
breastfeed.
It causes the intestinal tract of the newborn to produce antibodies. -
ANSWER-ANS: B
Alloimmunity occurs when an individual's immune system
reacts against antigens on the tissues of other members of the
same species. This can occur when a woman is Rh- negative
and gives birth to an Rh-positive baby, leading to hemolytic
anemia of the newborn. Rho[D] immunoglobulin does not
provide protection against infection, provide antibodies to a
bottle-fed baby, or cause the intestine to produce antibodies.
4 | P a g e
Tissue damage caused by the deposition of circulating immune
complexes containing an antibody against the host DNA is the
cause of which disease?
Hemolytic anemia
Pernicious anemia
Systemic lupus erythematosus
Myasthenia gravis - ANSWER-ANS: C
The deposition of circulating immune complexes containing
an antibody against the host DNA produces tissue damage in
individuals with systemic lupus erythematosus (SLE). That is
not a process in hemolytic anemia, pernicious anemia, or
myasthenia gravis.
A patient asks the healthcare professional why tissue damage
occurs in acute rejection after organ transplantation. What
response by the professional is best?
Th1 cells release cytokines that activate infiltrating macrophages,
and cytotoxic T cells directly attack the endothelial cells of the
transplanted tissue.
