A patient with no prenatal care is admitted to the labor and delivery unit.She is placed on an external fetal monitor, and an intravenous infusion is begun.
A tentative diagnosis of abruptio placentae is made.Which finding would support this diagnosis?

Sustained uterine hypertonicity.

Strong uterine contractions every 3-4 minutes.

Bile-colored vomitus.

Fetal heart rate acceleration with fetal activity.

Answer and Explanation

The Correct Answer is A

This means that the uterus is constantly contracted and does not relax between contractions. This can cause the placenta to separate from the uterine wall, which is called placental abruption or abruptio placentae. Placental abruption can deprive the baby of oxygen and nutrients and cause heavy bleeding in the mother.

Choice B is wrong because strong uterine contractions every 3-4 minutes are normal during labor and do not indicate placental abruption.

Choice C is wrong because bile-colored vomitus is not a sign of placental abruption, but rather a sign of hyperemesis gravidarum, a severe form of nausea and vomiting during pregnancy.

Choice D is wrong because fetal heart rate acceleration with fetal activity is a normal finding and indicates a healthy baby. Placental abruption can cause fetal distress and a decrease in fetal heart rate.

Correct Answer is A

Explanation

The correct answer is choice A. A patient who weighed less than 5 lb (2,268 gm) at birth is at risk for having an infant with intrauterine growth retardation (IUGR).This is because low birth weight is a possible indicator of genetic factors or placental insufficiency that can affect fetal growth.

Choice B is wrong because an ectopic pregnancy one year ago does not increase the risk of IUGR.An ectopic pregnancy is when the fertilized egg implants outside the uterus, usually in the fallopian tube.It does not affect the placental function or fetal development in a subsequent pregnancy.

Choice C is wrong because a mitral valve prolapse does not increase the risk of IUGR.

A mitral valve prolapse is when the valve between the left atrium and left ventricle of the heart does not close properly.It usually does not cause any symptoms or complications during pregnancy, unless it is associated with severe regurgitation or arrhythmias.

Choice D is wrong because the father’s age of 42 years old does not increase the risk of IUGR.The father’s age may affect the risk of chromosomal abnormalities or congenital anomalies in the fetus, but not the fetal growth.

Some of the other risk factors for IUGR include maternal smoking, alcohol, or drug use, medical conditions like anemia or lupus, infections such as rubella or syphilis, carrying twins or multiples, high blood pressure, gestational diabetes, and placenta problems.

A. The increase in the level of placental hormones tends to result in chelation of maternal iron. B. Fetal demand for iron is greater than the maternal intake. C. During the latter half of pregnancy, the maternal intestinal absorption of iron is decreased. D. The increase in maternal blood volume is greater than the increase in maternal red blood cells.

Correct Answer is D

Explanation

The correct answer is choice D. The increase in maternal blood volume is greater than the increase in maternal red blood cells.

This means that the concentration of hemoglobin and hematocrit in the blood is diluted by the extra fluid.

This is a normal physiological adaptation to pregnancy and does not indicate iron deficiency anemia.

Choice A is wrong because placental hormones do not chelate maternal iron.

Chelation is a process of binding metal ions to organic molecules, which is not relevant to this question.

Choice B is wrong because fetal demand for iron is not greater than maternal intake.

The mother can meet the iron needs of the fetus by increasing her dietary intake and taking iron supplements.

Choice C is wrong because maternal intestinal absorption of iron is not decreased during pregnancy.

In fact, it may be increased due to higher levels of estrogen and progesterone.
