Which of the following changes are not likely during pregnancy?: (A) A reduction in platelet concentration to the lower end of normal value, (B) Increase in the white cell count, (C) Increase in the levels of factor VII, VIII & X, (D) Decrease in vital capacity
Answer is D. The vital capacity doesn't change in pregnancy, its the tidal volume that expands into the ERV & IRV. The levels of factor VII ,VIII & X is usually at least double the non-pregnant state. The increase in WBC and ESR during pregnancy causes difficulty in diagnosing infections as well.
