  • 400869 & 400213

    The first's explanation says: "After giving blood your body has less blood = less haemoglobin = less oxygen available = hypoxia"
    The second one: "The reduction in blood pressure is the potential problem.".

    It seems like there are contraticting each other.

    Thanks!!

    I don't think they are contradictory. The issue is that there is a shortage of blood and consequently a shortage of haemoglobin. However, the haemoglobin levels, as a percentage of the blood remain unchanged.

      But the shortage of haemoglobin is never put as the right answer.

      Question 400869 puts as right answer "You are more susceptible to hypoxia after a blood-donation" having "Your blood-pressure is too low after blood-donation" as an option.
      Question 400213 puts "Because there is a small increased risk of low blood pressure due to loss of blood volume." over "The haemoglobin level is too low".

      Do you see what i mean?

      Thank you for answering!

        Ok, I thought you were querying the haemoglobin. I which case, notice the second one is acknowledging 'small' increased risk e.g this is not the major reason.

          Ok perfect, so:
          BIG risk-->Hypoxia
          SMALL risk-->Low blood pressure.

          Great support, cheers!
