Which of the following blood types would the nurse identify as the rarest?

  • A. A
  • B. AB
  • C. B
  • D. O
Correct Answer: B

Rationale: The correct answer is B (AB). AB blood type is the rarest because it is a result of inheriting both A and B alleles, making it less common in the population. AB individuals can only receive blood from other AB individuals due to their unique antigens. Blood types A, B, and O are more common in the population, with O being the most common as it is the universal donor. Blood type A and B are more common than AB since they only require one allele for their respective antigens. Thus, the rarity of AB blood type is due to the inheritance of both A and B alleles, making it the least common among the choices provided.
