Included in the definition of tachysystole is:
Contraction duration of less than 40 seconds.
Contraction frequency of greater than 5 in 10 minutes.
Contraction intensity of less than 80 mm Hg.
Resting tone of less than 18 mm Hg.
The Correct Answer is B
Choice A rationale
Contraction duration less than 40 seconds doesn't define tachysystole. Tachysystole focuses on frequency, not duration, of contractions over a specific time frame.
Choice B rationale
Contraction frequency of more than 5 in 10 minutes defines tachysystole. This frequency indicates excessive uterine activity, requiring intervention to prevent fetal distress.
Choice C rationale
Contraction intensity less than 80 mm Hg does not define tachysystole. Intensity relates to contraction strength, but tachysystole is about frequency exceeding the normal range.
Choice D rationale
Resting tone less than 18 mm Hg isn't part of tachysystole's definition. Tachysystole pertains to contraction frequency, not resting tone, which measures uterine relaxation between contractions.

Correct Answer is D
Explanation
Choice A rationale
Bleeding is typically not associated with a vaginal hematoma; it is more indicative of other postpartum complications such as uterine atony or retained placenta fragments.
Choice B rationale
Warmth is usually associated with infection or inflammation. A hematoma is a collection of clotted blood outside the blood vessels, not typically characterized by warmth.
Choice C rationale
Redness might be seen in cases of infection or inflammation. A vaginal hematoma is a localized collection of blood and does not inherently cause redness.
Choice D rationale
Pain is a common symptom of a vaginal hematoma due to the pressure and swelling from the accumulated blood.
Correct Answer is A
Explanation
Choice A rationale
Blood pressure of 160/110 indicates severe preeclampsia and warrants immediate intervention to prevent complications. Stopping oxytocin is part of the management of severe
preeclampsia to avoid exacerbating the condition.
Choice B rationale
Frequency of contractions every 3 minutes is within the normal range during labor induction and does not warrant stopping the infusion unless there are other concerns.
Choice C rationale
A fetal heart rate of 155 bpm with early decelerations may require close monitoring but does not necessarily warrant stopping the oxytocin infusion. Early decelerations are typically a
normal physiological response.
Choice D rationale
Frequency of contractions every 3 minutes is expected during active labor and is generally not a cause to stop the oxytocin infusion. The nurse should continue to monitor the labor
progression closely.
