The nursing instructor is preparing to illustrate the various changes between the nonpregnant and pregnant female bodies.
The instructor should point out that the blood volume in the pregnant woman can increase by what percentage?
20% to 25%.
40% to 45%.
50% to 55%.
30% to 35%.
The Correct Answer is B
Blood volume increases significantly within the first few weeks of gestation and increases progressively throughout the pregnancy.
The total blood volume increase varies from 20% to 100% above prepregnancy levels, usually close to 45%1.
Choice A is incorrect because the increase is usually close to 45%, not 20% to 25%.
Choice C is incorrect because the increase is usually close to 45%, not 50% to 55%.
Choice D is incorrect because the increase is usually close to 45%, not 30% to 35%.

It is used to check for developmental dysplasia of the hip (DDH).

Choice B is not an answer because genu valgum is a condition where the knees angle in and touch each other when the legs are straightened, and it is not a screening test for DDH.
Choice C is not an answer because the Adams test is used to screen for scoliosis, not DDH.
