All of the following changes are seen in pregnancy except:
Ans. is d, i.e. Increased peripheral vascular resistanceRef: Dutta Obs. 7/e, p 51-53As discussed in detail:Blood volume increases during pregnancyCardiac output = Stroke volume x Heart rateAll these three parameters increase during pregnancyIn pregnancy since the main hormone is progesterone, which has a smooth muscle relaxant effect so peripheral vascular resistance decreases during pregnancy (and not increases).
Increased stroke volume
Increased cardiac output
Increased Intravascular volume
Increased peripheral vascular resistance
