When administering Pitocin, you should start at a low dose and work your way up slowly to a dose that provides the best contraction rate.
True
False
The Correct Answer is A
Choice A rationale
Starting Pitocin at a low dose minimizes the risk of uterine hyperstimulation, which can cause fetal distress. Gradually increasing the dose allows careful monitoring of the mother’s and fetus’s responses for optimal contraction rate.
Choice B rationale
Administering Pitocin without starting at a low dose increases the risk of uterine tachysystole, leading to potential complications like uterine rupture or placental abruption. A gradual increase ensures safer labor progression.

Correct Answer is D
Explanation
Choice A rationale
The maternal-fetal exchange of oxygen and waste products is affected by uterine contractions, as these compress the placental blood vessels, temporarily reducing blood flow.
Choice B rationale
Blood pressure variations during labor can influence perfusion but do not increase maternal-fetal exchange as uterine contractions primarily cause transient vascular compression.
Choice C rationale
Maternal-fetal exchange continues during contractions except when the uterine pressure is high enough to occlude placental blood flow, temporarily halting the exchange.
Choice D rationale
Uterine contractions compress the spiral arteries, reducing blood flow through the placenta, thereby diminishing maternal-fetal exchange of oxygen and waste products during contractions.
Correct Answer is A
Explanation
Choice A rationale
Fetal sleep cycles cause temporary decreased variability in FHR, typically lasting 20 minutes or less. FHR baseline remains normal. Normal FHR variability is 6-25 bpm.
Choice B rationale
Head compression during contractions leads to early decelerations in FHR, not decreased variability. Early decelerations are a normal response to pressure on the fetal head.
Choice C rationale
Fetal hypoxemia causes decreased variability but usually persists for longer than 20 minutes. It indicates compromised oxygen supply, requiring immediate intervention.
Choice D rationale
Umbilical cord compression leads to variable decelerations in FHR rather than decreased variability. These decelerations vary in onset, duration, and intensity.
