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 C
Explanation
The correct answer is choice C. Count the time from the beginning of one contraction to the end of the same contraction.
This is because the duration of a contraction is the length of time that the uterine muscle is tightening and relaxing.
The duration is measured from the start of one contraction until the end of that same contraction.
Choice A is wrong because it measures the frequency of contractions, not the duration.
The frequency is the time between the start of one contraction and the start of the next one.
Choice B is wrong because it measures only half of the duration of a contraction.
The middle of a contraction is when the uterine muscle reaches its peak intensity and then starts to relax.
Choice D is wrong because it measures both the duration and the interval of contractions.
The interval is the time between the end of one contraction and the start of the next one.
Normal ranges for contractions during labor are:
• Duration: 30 to 90 seconds
• Frequency: 2 to 5 minutes apart
• Interval: 30 to 120 seconds
Correct Answer is D
Explanation
The correct answer is choice D. “Have you noticed any tenderness in your breasts?”
Breast tenderness is one of the early signs of pregnancy that may occur as early as one to two weeks after conception.It is caused by hormonal changes that prepare the breasts for lactation.
Choice A is wrong because shortness of breath is not a sign of early pregnancy.It may occur later in pregnancy due to the growing uterus pressing on the diaphragm.
Choice B is wrong because episodes of loss of consciousness are not a sign of early pregnancy.They may indicate a serious condition such as anemia, dehydration, or hypoglycemia that requires medical attention.
Choice C is wrong because spotting is not a sign of early pregnancy.
It may be a sign of implantation bleeding, which occurs when the fertilized egg attaches to the lining of the uterus.However, implantation bleeding is usually much lighter and shorter than a normal period.
