                   226. Answer: 2


                  Rationale: A normal fetal heart rate is 110 to 160 beats per minute. A fetal heart
               rate of 180 beats per minute could indicate fetal distress and would warrant
               immediate notification of the PHCP. By full term, a normal maternal hemoglobin
               range is 11 to 13 g/dL (110 to 130 mmol/L) because of the hemodilution caused by an
               increase in plasma volume during pregnancy. The maternal pulse rate during
               pregnancy increases 10 to 15 beats per minute over prepregnancy readings to
               facilitate increased cardiac output, oxygen transport, and kidney filtration. White
               blood cell counts in a normal pregnancy begin to increase in the second trimester
                                                                                              3
               and peak in the third trimester, with a normal range of, 11,000–15,000/mm  (11–15 ×

               10 /L) up to 18,000/mm  (18 × 10 /L) During the immediate postpartum period, the
                                                                   3
                                                                                9
               white blood cell count may be 25,000–30,000/mm  (25–30 × 10 /L) because of
               increased leukocytosis that occurs during delivery.
                  Test-Taking Strategy: Focus on the subject, normal assessment and laboratory
               findings and those that indicate the need to contact the PHCP. Knowledge regarding
               the normal and abnormal findings in a pregnant client and fetus will direct you to
               the correct option.

                   227. Answer: 3


                  Rationale: Station is the measurement of the progress of descent in centimeters
               above or below the midplane from the presenting part to the ischial spine. It is
               measured in centimeters and noted as a negative number above the line and as a
               positive number below the line. At the negative 1 (−1) station, the fetal presenting
               part is 1 cm above the ischial spine. Option 1 is at the negative 5 (−5) station and the
               fetal presenting part is 5 cm above the ischial spine. Option 2 is at the negative 2 (−2)
               station, and the fetal presenting part is 2 cm above the ischial spine. Option 5 is at
               the positive 3 (+ 3), and the fetal presenting part is 2 cm below the ischial spine.
                  Test-Taking Strategy: Recalling that station is measured in centimeters and uses
               the ischial spine as a reference point will assist in answering this question. Focus on
               the data in the question and note the location of the ischial spine and that the
               stations range from −5 cm to + 5 cm above or below this reference point.
