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 ["B","C","D","E","F"]

Explanation

A. "I will inject this medication under your skin.": Tocolytic medications are typically administered orally, intravenously, or intramuscularly, not subcutaneously.

B. "You may experience a headache after receiving this medication."
Some tocolytic medications can cause headaches as a side effect.


C. "It is common for this medication to make you feel jittery."
Tocolytic medications, such as terbutaline, can cause nervousness or jitteriness.

D. "This medication should decrease your contractions."
The primary purpose of tocolytic medication is to decrease uterine contractions and delay preterm labor.


E. "I'll check your reflexes frequently while you are receiving this medication."
Some tocolytic medications, like magnesium sulfate, require monitoring of deep tendon reflexes to assess for potential toxicity.


F. "This medication can make your heart beat faster."
Tocolytic medications, such as terbutaline, can increase heart rate.


G. "This medication can increase your blood pressure.":

Some tocolytic medications, like magnesium sulfate, can actually lower blood pressure rather than increase it.

Correct Answer is B

Explanation

Choice A rationale

Elevated BUN levels (25 mg/dL) can indicate kidney dysfunction, dehydration, or high protein intake. However, it’s not directly related to a prenatal complication, though it still

requires monitoring.

Choice B rationale

Hemoglobin (Hgb) of 10.2 mg/dL is below the normal range (11 to 16 mg/dL) and can indicate anemia. During pregnancy, anemia can lead to serious complications such as preterm

birth and low birth weight, making this result significant.

Choice C rationale

A fasting blood glucose level of 70 mg/dL falls within the normal range (70 to 110 mg/dL) and does not indicate a complication. Thus, it is not concerning in the context of prenatal

complications.

Choice D rationale

Hematocrit (Hct) of 32% is slightly below the normal range (33 to 47%), which can be common in pregnancy due to increased plasma volume. While monitoring is required, it’s not as

critical as anemia.
