Explanation

Blood volume increases significantly within the first few weeks of gestation and increases progressively throughout the pregnancy.

Choice D is incorrect because the increase is usually close to 45%, not 30% to 35%.

A. Risk for Down syndrome. B. Risk for neural tube defects. C. Further testing is required. D. Test needs to be repeated.

Correct Answer is C

Explanation

Elevated levels of MSAFP may indicate that the baby is at risk of a neural tube defect, like spina bifida.
However, further testing is required to confirm the results and determine the cause of the elevated levels.

Choice A is incorrect because low levels of MSAFP may indicate a risk for Down syndrome, not elevated levels.
Choice B is incorrect because while elevated levels of MSAFP may indicate a risk for neural tube defects, further testing is required to confirm this.
Choice D is incorrect because while repeating the test may be necessary, further testing beyond just repeating the MSAFP screening may also be required.
