Answer to Question 1

B

Feedback
A Splitting of S1 and S2 is more audible.
B Between 14 and 20 weeks of gestation, the pulse increases about 10 to 15 beats/min, which persists to term.
C In the first trimester, blood pressure usually remains the same as at the prepreg-nancy level, but it gradually decreases up to about 20 weeks of gestation. During the second trimester both the systolic and diastolic pressures decrease by about 5 to 10 mm Hg.
D Production of RBCs accelerates during pregnancy.

Answer to Question 2

C, E
Feedback
Correct The results of the screening test are valid if the child acted in a normal and
expected manner. The child's chronologic age in years, months, and days
must be calculated in order to draw the age line. This is necessary in order
to perform an accurate DDST-II. Reliability and validity of the test can be
altered if the child is not feeling well or is under the influence of
medications.
Incorrect The child's height and weight are not relevant to the DDST-II screening
process. The parent's ability to understand the results of the screening is
not relevant to the validity of the test. The parent-child interaction is not
significantly relevant to the test results.
