Question

If Linda’s red blood cell count was low, what is your prediction of her reticulocyte count (assuming her bone marrow is working normally)?

A) low

B) normal

C) high

As a bruise (ecchymosis = blood in the tissues) heals, it progresses through several stages marked by color variations (from dark blue to greenish to yellow) before fading. Which molecules are responsible for the color variations?

A) deoxy-hemoglobin -> bilirubin -> biliverdin

B) oxy-hemoglobin -> bilirubin -> biliverdin

C) deoxy-hemoglobin -> biliverdin -> bilirubin

D) transferrin -> biliverdin -> bilirubin

E) erythropoietin -> bilirubin -> biliverdin

Answer 1

1. High

If bone marrow is functioning properly and RBC is low it predicts that reticulocyte count will be high and the person has Hemolytic anemia. In this case, RBC dies before they would normally die.

2. Option C is correct

deoxy-hemoglobin -> biliverdin -> bilirubin
