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 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.

Correct Answer is B

Explanation

Choice A rationale

Checking for ketones in urine is related to metabolic conditions like diabetic ketoacidosis, not directly relevant to the immediate care of an eclamptic client.

Choice B rationale

Padding the bed rails and headboard helps prevent injury during seizures, which is crucial in managing a client with eclampsia.

Choice C rationale

Providing visual and auditory stimulation can increase the risk of further seizures in an eclamptic client. Reducing stimulation is usually recommended.

Choice D rationale

Placing the bed in the high Fowler's position is not appropriate for managing a client post-seizure. The priority is ensuring airway patency and preventing injury.
