Answers | Verified & Revised Answers (NEW)!
Question 1
The B-cell receptor (BCR) complex functions uniquely by:
A) communicating information about the anitgen to the helper T (Th) cell
B) secreting chemical signals to help cells communicate
C) recognizing the anitgen on the surface of the B lymphocyte
D) communicating information about the antigen to the cell nucleus
Correct Answer
Ans: D- communicating information about the antigen to the cell nucleus
Question 2
What causes the clinical manifestations of confusion, convulsions, cerebral hemorrhage, and coma in hypernatremia?
A) high sodium in the blood vessels pulls water out of the brain cells into the blood vessels, causing brain cells to shrink
B) high sodium in the brain cells pulls water out of the blood vessels into the brain cells, causing them to swell
C) high sodium in the blood vessels pulls potassium out of the brain cells, which slows the synapses in the brain
D) high sodium in the blood vessels draws chloride into the brain cells followed by water, causing the brain cells to swell
Correct Answer
Ans: A- high sodium in the blood vessels pulls water out of the brain cells into the blood vessels, causing brain cells to
shrink

Correct Answer
Ans: B- suppression of the bone marrow to produce adequate amounts of erythrocytes, leukocytes, and thrombocytes

, Question 5
When diagnosed with hemolytic disease of the newborn (HDN), why does the newborn develop hyperbilirubinemia after
birth but not in utero?
A) excretion of unconjugated bilirubin through the placenta into the mother's circulation is no longer possible
B) hemoglobin does now break down inot bilirubin in the intrauterin environment
C) the liver of the fetus is too immature to conjugate bilirubin from a lipid-soluble form to a water-soluble form
D) the destruction of erythtocytes producing bilirubin is greater after birth
Correct Answer
Ans: A- excretion of unconjugated bilirubin through the placenta into the mother's circulation is no longer possible
