A nurse is assessing a client who has placenta previa and is receiving fetal monitoring.
Which of the following clinical findings should the nurse expect?

A.

Variable decelerations.

B.

Painless vaginal bleeding.

C.

Rigid abdomen.

D.

Uterine tachysystole.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Variable decelerations are associated with umbilical cord compression, not placenta previa. In placenta previa, the placenta covers the cervical os, but it does not typically cause

variable decelerations on fetal monitoring.

 

Choice B rationale

Painless vaginal bleeding is a hallmark sign of placenta previa. This occurs because the placenta is located near or over the cervical os, leading to bleeding when the cervix dilates

or effaces.

 

Choice C rationale

A rigid abdomen is more indicative of placental abruption, where the placenta detaches prematurely from the uterine wall, causing pain and a tense abdomen, not typically seen in

placenta previa.

 

Choice D rationale

Uterine tachysystole is characterized by excessive uterine contractions and is not a clinical finding related to placenta previa. Tachysystole often results from excessive oxytocin use

or other uterine stimulants.

Correct Answer is D

Explanation

Choice A rationale

Only one dose of rubella immunization is necessary post-delivery, no need for a second dose in 2 weeks.

Choice B rationale

Prevention of pregnancy is recommended for at least 1 month (not 4 months) after receiving the rubella vaccine to avoid possible teratogenic effects.

Choice C rationale

An additional rubella immunization is not recommended during pregnancy as the live vaccine is contraindicated during gestation.

Choice D rationale

Rubella vaccine is safe for breastfeeding mothers, as it does not affect the safety of breast milk.

Correct Answer is D

Explanation

Choice A rationale

Uterine contractions occur more frequently than every 15 minutes during the active phase of labor, typically every 2-3 minutes.

Choice B rationale

A fetal heart rate baseline of 166/min is considered tachycardia and may not be normal during labor.

Choice C rationale

Late decelerations are concerning and not expected as they may indicate fetal distress.

Choice D rationale

Contractions lasting about 75 seconds are expected during the active phase of labor.
