A pregnant client at 22 weeks’ gestation has a hematocrit of 35%. Pre-pregnancy hematocrit was 40%. Which of the following statements by the nurse best explains this change?

Because of your pregnancy, you’re not eating enough iron-rich foods.

Because of your pregnancy, you’re developing a serious problem.

Because of your pregnancy, you’re making more blood.

Because of your pregnancy, you’re not making enough new blood cells.

Answer and Explanation

The Correct Answer is C

Choice A rationale
While iron-rich foods are important, the decrease in hematocrit is primarily due to hemodilution rather than inadequate iron intake. Hemodilution occurs as plasma volume increases more than red cell mass.
Choice B rationale
Hematocrit changes in pregnancy are typically not indicative of a serious problem but a normal physiological adaptation. Hemodilution reduces hematocrit without indicating a pathological condition.
Choice C rationale
During pregnancy, plasma volume increases by approximately 50%, while red cell mass increases by about 30%, leading to hemodilution. This physiological change results in a lower hematocrit value.
Choice D rationale
Although hematocrit decreases due to hemodilution, it does not mean that there is a deficiency in red blood cell production. It reflects the dilution effect of increased plasma volume during pregnancy.

Correct Answer is C

Explanation

Choice A rationale
Calculating from the LMP of February 14, 2019, the estimated date of birth using Naegele's rule would not fall in September.
Choice B rationale
Naegele's rule calculates EDB by adding 7 days to the LMP and then subtracting 3 months. This does not lead to a November date.
Choice C rationale
Using Naegele's rule, adding 7 days to February 14 results in February 21, 2019, then subtracting 3 months, results in November 2019.
Choice D rationale
While close, November 7 is not accurate. Naegele's rule would adjust from February 14, giving an EDB in mid to late November.

A. Valsalva maneuver. B. Ferguson’s reflex. C. Lightening. D. Molding.

Correct Answer is D

Explanation

Choice A rationale
Valsalva maneuver involves forced expiration against a closed airway, increasing intrathoracic pressure and used to aid in expelling the fetus during labor.
Choice B rationale
Ferguson’s reflex involves the release of oxytocin due to vaginal and cervical stretching, resulting in stronger contractions during the second stage of labor.
Choice C rationale
Lightening refers to the descent of the fetus into the pelvis before labor, relieving pressure on the diaphragm and easing breathing.
Choice D rationale
Molding is the slight overlapping of cranial bones, allowing the fetal head to shape and fit through the birth canal during labor.
