Included in the definition of tachysystole is:

A.

Contraction duration of less than 40 seconds.

B.

Contraction frequency of greater than 5 in 10 minutes.

C.

Contraction intensity of less than 80 mm Hg.

D.

Resting tone of less than 18 mm Hg.

Answer and Explanation

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 B

Explanation

Choice A rationale

Magnesium sulfate is not given to increase diuresis; this is not its primary effect and is incorrect in the context of treating preeclampsia.

Choice B rationale

Magnesium sulfate is administered to prevent seizures in patients with preeclampsia. It acts as a central nervous system depressant and helps in preventing eclampsia.

Choice C rationale

Although magnesium sulfate may have a mild effect on reducing blood pressure due to its vasodilatory properties, this is not its primary purpose in the management of preeclampsia.

Choice D rationale

Magnesium sulfate is not used to slow the process of labor; its main role is seizure prophylaxis in preeclampsia.

Correct Answer is C

Explanation

Choice A rationale

Decreased pain level can be an effect of addressing the cause of pain, but it doesn't indicate improved uterine tone or resolution of atony.

Choice B rationale

Stable blood pressure is important, but it is not the direct outcome of improved uterine tone or the resolution of uterine atony.

Choice C rationale

A firm fundus at or below the umbilicus indicates successful contraction of the uterus, resolving uterine atony and reducing bleeding.

Choice D rationale

Reduced lochial flow can indicate decreased bleeding, but it does not directly indicate improved uterine tone or resolution of uterine atony.
