Question

In an effort to reduce her weight. Vera has been living for foe past 6 months on a diet consisting mostly of white rice. She donated a little Mood for the physiology exercise and her colleagues a foe lab obtained the following values: What hematocrit would generate the value above? (You MUST show your work!) Put hematocrit value in the table above. Fill in the last column of the table, indicating which values are within the normal range, too low. Explain why Vera has a normal hematocrit, based on your conclusions about ha ocher blood values. What is the main cause of Vera s MCV mid MCHC blood values? Vera complains that she tires easily suggest an addition to her diet that might help. References Silverthorn ed'n pp.

Answer 1

Answer a:

Hematocrit % = (RBC count per mm³ ) X (MCV in mm³) X 100

RBC count=6.03 million = 6.03 x 10⁶ per mm³

MCV=68 micrometre³   = 68 x (10^-3)³mm³ = 68 x 10^-9 mm³    

Hematocrit % =( 6.03 x 10⁶) x (68 x 10^-9) x 100 =40%

Answer b:

• Red Cell Count normal range (Female) 4.2 - - 5.4 Thus 6.03 is above range
• MCV normal range is                           80 - - 100 Thus 68 is below range
• MCHC normal range is                             30 -- 34 Thus 24 is below range
• Hematocrit normal range is                   34.9 -- 44.5 Thus 40 is in normal range

Answer C: Hematocrit is in normal range as it depends on both RBC count and plasma Here Their is increase in RBC count but MCV is below range which compensate the increase count.

Answer D: Due to her diet (mainly white rice) she is deficient in Iron content in her body.
