A nurse is reviewing laboratory results of a pregnant patient.Which result will require further assessment?
Rubella titer 1:33.
Serologic test for syphilis (STS) - non-reactive.
Blood type A-negative.
Hemoglobin 12.2 gm/dL.
The Correct Answer is A
A rubella titer of 1:33 indicates a low level of immunity to rubella, which can be dangerous for a pregnant woman and her fetus.
Rubella is a viral infection that can cause birth defects or miscarriage if contracted during pregnancy. A rubella titer of 1:10 or higher is considered protective.
Choice B is wrong because a non-reactive serologic test for syphilis (STS) means that the patient does not have syphilis, which is a bacterial infection that can also harm the fetus if untreated.
Choice C is wrong because blood type A-negative does not require further assessment unless the patient has antibodies to the Rh factor, which can cause hemolytic disease of the newborn if the fetus is Rh-positive.
This can be prevented by giving the patient Rh immunoglobulin injections during pregnancy and after delivery.
Choice D is wrong because hemoglobin 12.2 gm/dL is within the normal range for a pregnant woman, which is 11 to 14 gm/dL.
Hemoglobin is the protein in red blood cells that carries oxygen.
A low hemoglobin level can indicate anemia, which can affect the oxygen delivery to the fetus and increase the risk of preterm labor or low birth weight.

Correct Answer is B
Explanation
The correct answer is choice B.“The placenta was blocking the opening of the womb.”
This statement shows that the patient understands that placenta previa is a condition where the placenta covers or is near the internal os of the cervix, which prevents a safe vaginal delivery.The patient would need a cesarean delivery to avoid bleeding and complications.
Choice A is wrong because it describes placental abruption, not placenta previa.
Placental abruption is when the placenta separates from the uterine wall before delivery, which can cause severe bleeding and fetal distress.
Choice C is wrong because it describes a normal position of the placenta at the top of the womb.
This does not interfere with vaginal delivery and does not cause bleeding.
Choice D is wrong because it describes placenta increta or percreta, not placenta previa.
Placenta increta or percreta is when the placenta grows too deeply into or through the uterine wall, which can cause severe bleeding and damage to the uterus and other organs.
Correct Answer is A
Explanation
The correct answer is choice A and it indicates fetal distress because it is a sign oflate deceleration.Late decelerations are due touteroplacental insufficiencyas the result of decreased blood flow and oxygen to the fetus during the uterine contractions.This causeshypoxemiaand can lead to fetal acidosis and neurological damage.
Choice B is wrong because it indicates anormal variabilityin the fetal heart rate, which reflects a healthy autonomic nervous system.A normal fetal heart rate is 120-160 beats per minute.
Choice C is wrong because it indicates anearly accelerationin the fetal heart rate, which is a benign finding that may occur with fetal movement or stimulation.
Choice D is wrong because it indicates anearly decelerationin the fetal heart rate, which is a normal response to fetal head compression during contractions.
It does not indicate fetal distress.
Normal ranges for fetal heart rate patterns are:
• Baseline: 120-160 beats per minute
• Variability: 6-25 beats per minute
• Accelerations: at least 15 beats per minute above baseline for at least 15 seconds
• Decelerations: none or early (mirror contractions)
