The nurse places a Toco (tocodynamometer) on a client admitted in early labor.
The nurse explains to the client that this device provides an accurate assessment of which of the following:
Frequency and intensity of contractions.
Frequency and intensity of contractions.
Uterine resting tone and hypertonus.
Duration of contractions only.
The Correct Answer is A
Choice A rationale
The tocodynamometer detects both the frequency and intensity of uterine contractions by measuring the pressure changes on the abdomen. It provides real-time data on contraction patterns during labor.
Choice B rationale
Repeating the frequency and intensity of contractions is redundant. The tocodynamometer accurately measures these parameters, providing essential information for managing labor progress.
Choice C rationale
While the tocodynamometer can infer uterine resting tone, it is not designed to measure hypertonus directly. Other methods, like intrauterine pressure catheters, offer more accurate assessments of uterine tone.
Choice D rationale
The tocodynamometer measures the duration of contractions, but it does not solely focus on this parameter. It captures comprehensive data, including frequency and intensity, for effective labor management.

Correct Answer is ["A","C","D"]
Explanation
Choice A rationale
Pitocin is used for augmentation of labor to increase uterine contractions' frequency and strength, enhancing labor progression in cases where labor is slow or stalled.
Choice B rationale
Pitocin does not increase prolactin receptor sites; instead, it focuses on enhancing uterine contractions during labor and addressing postpartum hemorrhage.
Choice C rationale
Pitocin is used for induction of labor to stimulate uterine contractions and initiate labor in women who need medical intervention for various reasons.
Choice D rationale
Pitocin helps decrease bleeding after delivery by promoting uterine contractions, which aid in reducing postpartum hemorrhage and expelling the placenta.
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.
