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

Explanation

Choice A rationale

During labor, the body experiences physiological stress, which typically causes an increase, not a decrease, in white blood cell (WBC) count. This increase is a normal response to stress.

Choice B rationale

Blood glucose levels can decrease during labor due to the energy expenditure and physiological demands of the process. This is why it is important to monitor glucose levels and provide necessary interventions if hypoglycemia occurs.

Choice C rationale

The respiratory rate generally increases during labor to meet the increased oxygen demands of the body. A decrease in respiratory rate is not expected during this time.

Choice D rationale

Body temperature may increase slightly during labor due to the physical exertion and metabolic activity involved. A decrease in temperature is not a typical finding during labor.

Correct Answer is C

Explanation

Choice A rationale

Gaining 2 pounds per week throughout the rest of pregnancy is excessive and not recommended. Normal weight gain is approximately 1 pound per week in the second and third trimesters.

Choice B rationale

Dieting during pregnancy can lead to inadequate nutrient intake for both the mother and the developing fetus. It is essential to focus on a balanced diet rather than trying to lose weight.

Choice C rationale

Meeting with a dietitian can help the client assess their nutritional needs and develop a healthy eating plan to support their pregnancy, ensuring both maternal and fetal health.

Choice D rationale

Eating an additional 700 calories per day is too high. Generally, an additional 300-500 calories per day is recommended during the second and third trimesters to support pregnancy.
