A nurse is walking by a client's room and can hear the fetal heart rate dropping.
The nurse observes the heartbeat and interprets the monitor strip as indicating which of the following?

A.

Uteroplacental insufficiency.

B.

Umbilical cord compression.

C.

Maternal bradycardia.

D.

Fetal head compression.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Uteroplacental insufficiency typically results in late decelerations, not a sudden drop in fetal heart rate, which is more commonly caused by umbilical cord compression.

 

Choice B rationale

Umbilical cord compression can cause variable decelerations, which are characterized by a sudden drop in fetal heart rate. This occurs due to the umbilical cord being compressed,

leading to decreased blood flow and oxygen to the fetus.

 

Choice C rationale

Maternal bradycardia refers to a slow maternal heart rate and does not directly cause changes in the fetal heart rate pattern.

 

Choice D rationale

Fetal head compression typically causes early decelerations, which are gradual decreases in fetal heart rate that occur with contractions and are usually benign.

Correct Answer is C

Explanation

Choice A rationale

A 10% to 15% increase in blood volume during pregnancy is too low compared to the average physiological changes that occur.

Choice B rationale

A 20% to 30% increase in blood volume is also below the expected range of increase during pregnancy.

Choice C rationale

Blood volume typically increases by 40% to 50% during pregnancy. This significant increase supports the demands of the growing fetus and placenta and prepares the mother's body for the blood loss that occurs during delivery.

Choice D rationale

A 65% to 75% increase is an overestimate. Such an extensive increase would be abnormal and is not typical in healthy pregnancies.

Correct Answer is D

Explanation

Choice A rationale

Severe nausea and vomiting, known as hyperemesis gravidarum, are more commonly associated with high levels of human chorionic gonadotropin (hCG) and are not specific to

ectopic pregnancy.

Choice B rationale

While vaginal bleeding can occur in an ectopic pregnancy, it is usually not a large amount. The bleeding in ectopic pregnancy tends to be light and irregular.

Choice C rationale

Uterine enlargement greater than expected for gestational age is typically associated with conditions like molar pregnancy, not ectopic pregnancy, as the pregnancy is located outside

the uterus.

Choice D rationale

Unilateral, cramp-like abdominal pain is a classic symptom of ectopic pregnancy as the fertilized egg implants outside the uterus, most commonly in a fallopian tube, causing

localized pain.
