Verified Answers)
Which of the following doses of RhoGAM is appropriate for a pregnant client
at 28 weeks gestation? ✔️Ans - 300 mcg in an unsensitized clinet
Rationale: An Rh-negative unsensitized woman should be given 300 mcg of
RhoGAM at 28 weeks after an indirect Coombs test is done to verify that
sensitization hasn't occurred. For a 1st trimester abortion or ectopic
pregnancy, 50 mcg of RhoGAM is given.
Before placenta functions, the corpus luteum is the primary source for
synthesis of which of the following hormones? ✔️Ans - Estrogen and
progesterone
Rationale: corpus luteum produces progesterone and estrogen for first 8-10
weeks of pregnancy until placenta takes over this function. High levels of
estrogen and progesterone cause suppression of LH and FSH.
Which of the following changes in respiratory functioning during pregnancy is
considered normal? ✔️Ans - Increased tidal volume
Rationale: A pregnant client breathes deeper, which increases tidal volume of
gas moved in and out of the respiratory tract with each breath. The expiratory
volume and residual volume decrease as the pregnancy progresses.
Inspiratory capacity increases. Oxygen consumption is 15-20% greater than
non-pregnant state.
Which of the following terms applies to the tiny, blanched, slightly raised end
arterioles found on the face, neck, arms, and chest during pregnancy? ✔️Ans
- Telangiectasias

Hyperemesis gravidarum ✔️Ans - results in electrolyte imbalance and
weight loss
Predisposing factors to developing hyperemesis gravidarum: ✔️Ans -
Trophoblastic disease
Obesity
