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.

Answer and Explanation

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. Syphilis.A negative rapid plasma reagin (RPR) test indicates that a patient is probably not infected with syphilis, a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum.The RPR test works by detecting the nonspecific antibodies that your body produces while fighting the infection.

Choice A is wrong because herpes simplex II is a viral infection that causes genital herpes, and it is not detected by the RPR test.

Choice C is wrong because gonorrhea is a bacterial infection caused by Neisseria gonorrhoeae, and it is also not detected by the RPR test.

Choice D is wrong because condylomata are genital warts caused by human papillomavirus (HPV), and they are not detected by the RPR test either.

The RPR test is a screening test, and it can give false-positive results due to other conditions or infections.Therefore, a positive RPR test should always be confirmed by a more specific treponemal test, such as TPPA or FTA-ABS.The RPR test can also be used to monitor the treatment response of syphilis, as the antibody levels should decrease after effective antibiotic therapy.

A. The newborn’s nostrils flare slightly during respiration. B. The newborn’s hands and feet are blue and feel cool. C. The newborn’s eyes move randomly when his head is turned to the side. D. The newborn’s tongue thrusts forward when it is lightly touched.

Correct Answer is A

Explanation

The correct answer is choice A. The newborn’s nostrils flare slightly during respiration.This is a sign of respiratory distress in a newborn.

Flaring nostrils indicate that the newborn is working hard to breathe and may not be getting enough oxygen.

Choice B is wrong because the newborn’s hands and feet are blue and feel cool.This is a normal finding called acrocyanosis, which occurs due to immature peripheral circulation.

It usually resolves within 24 to 48 hours after birth.

Choice C is wrong because the newborn’s eyes move randomly when his head is turned to the side.This is a normal finding called nystagmus, which occurs due to immature eye muscles and coordination.

It usually disappears by 6 months of age.

Choice D is wrong because the newborn’s tongue thrusts forward when it is lightly touched.This is a normal finding called the extrusion reflex, which helps the newborn to suck and swallow.

It usually fades by 4 months of age.
