When a pregnant patient has genital herpes, for which complication is the patient at higher risk than the general population?

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.

The correct answer is choice D. Presence of human chorionic gonadotropin (hCG) in blood.This is apositive sign of pregnancythat can only be attributed to a fetus.hCG is a hormone produced by the placenta that can be detected in blood or urine tests.

Choice A. Quickening.This is apresumptive sign of pregnancythat is based on the woman’s report of feeling fetal movements in her lower abdomen.This can occur at 16 weeks for second time moms and around 20 weeks for first time moms.However, this sign is not conclusive as other conditions can cause similar sensations.

Choice B. Uterine enlargement.This is aprobable sign of pregnancythat can be observed by the nurse or doctor through palpation.However, this sign does not mean 100% that a baby is growing in the uterus as it can be due to other causes such as fibroids or tumors.

Choice C. Urinary frequency.This is apresumptive sign of pregnancythat is based on the woman’s report of needing to urinate more often than usual.This can be caused by hormonal changes and increased blood volume during pregnancy.However, this sign is not definitive as other conditions such as urinary tract infections or diabetes can also cause frequent urination.
