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

Contraction duration less than 40 seconds doesn't define tachysystole. Tachysystole focuses on excessive frequency of contractions rather than their duration.

Choice B rationale

Contraction frequency of more than 5 in 10 minutes defines tachysystole. This condition indicates too frequent uterine activity, which can compromise fetal oxygenation.

Choice C rationale

Contraction intensity less than 80 mm Hg doesn't define tachysystole. Tachysystole is characterized by the number of contractions, not their intensity.

Choice D rationale

Resting tone less than 18 mm Hg is not related to the definition of tachysystole. Tachysystole concerns contraction frequency, not the resting tone of the uterus between contractions. .

Correct Answer is B

Explanation

Choice A rationale

While infection prevention is vital, ensuring breathing function is more critical after ASP.

Choice B rationale

ASP affects the respiratory system severely; thus, restoring normal breathing is a primary goal.

Choice C rationale

Gastrointestinal function is less immediately affected by ASP compared to respiratory issues.

Choice D rationale

Voiding without pain is important, but respiratory stability takes precedence.
