A nurse is caring for a client who is at 32 weeks of gestation and is in labor. Which of the following medications is contraindicated for this client?
Misoprostol
Folic acid
Nifedipine
Terbutaline sulfate
The Correct Answer is A
Choice A rationale: Misoprostol is a prostaglandin analog and is contraindicated for use during labor at 32 weeks of gestation as it can lead to uterine hyperstimulation, which may pose a risk to the preterm fetus.
Choice B rationale: Folic acid is a vitamin supplement and is not contraindicated during labor. However, it is typically taken earlier in pregnancy to prevent neural tube defects.
Choice C rationale: Nifedipine is a calcium channel blocker that may be used to suppress preterm labor, and it is not contraindicated at 32 weeks of gestation.
Choice D rationale: Terbutaline is a beta-adrenergic agonist that may be used to relax the uterine smooth muscles and inhibit preterm labor. It is not contraindicated at 32 weeks of gestation.

Correct Answer is A
Explanation
Choice A rationale: Auscultating fetal heart tones in the right upper quadrant is not appropriate based on the information provided by Leopold maneuvers, which indicates the fetal back is on the right side of the mother's abdomen, and the fetal head is in the fundal portion of the uterus.
Choice B rationale: During Leopold maneuvers, the nurse palpated a round, firm, movable part in the fundal portion of the uterus. This finding corresponds to the fetal head, which is typically located at the top of the uterus (fundus). Additionally, the nurse palpated a long, smooth surface on the mother's right side. This finding indicates the fetal back, which typically lies along the right side of the mother's abdomen, suggesting that the fetus's back is positioned anteriorly (toward the mother's front). The location of the fetal heart is typically best heard over the back of the fetus. Therefore, the nurse should auscultate the fetal heart tones in the maternal quadrant corresponding to the back of the fetus, which is the left lower quadrant.
Choice C rationale: The information from Leopold maneuvers does not indicate the fetal back is in the right lower quadrant. The nurse should not auscultate fetal heart tones in this area.
Choice D rationale: Auscultating fetal heart tones in the left upper quadrant is not appropriate based on the information provided by Leopold maneuvers, which indicates the fetal head is in the fundal portion of the uterus and the fetal back is on the right side of the mother's abdomen. The fetal heart is usually best heard over the back of the fetus, which is not in the left upper quadrant.
Correct Answer is C
Explanation
Choice A rationale:
A gynaecoid pelvis is considered the most favorable pelvic shape for childbirth and is not a contributing cause of difficult, prolonged labor.
Choice B rationale:
A longitudinal fetal lie (baby's spine aligned with the mother's spine) is a normal and favorable presentation for birth and is not a contributing cause of difficult, prolonged labor.
Choice C rationale:
A persistent occiput posterior position (baby's head facing the mother's abdomen instead of her back) can be a contributing cause of difficult, prolonged labor and may lead to a severe backache for the mother.
Choice D rationale:
Fetal attitude in general flexion (baby's head flexed forward, chin to chest) is a normal and favorable presentation for birth and is not a contributing cause of difficult, prolonged labor.
