A nurse is reinforcing teaching with a client who is at 38 weeks of gestation and has a positive group B streptococcus B-hemolytic screening.
Which of the following medications should the nurse discuss as the prophylaxis treatment during labor for this client?
Penicillin.
Cefazolin.
Erythromycin.
Vancomycin.
The Correct Answer is A
Choice A rationale
Penicillin is the recommended prophylactic treatment for a client at 38 weeks of gestation with a positive group B streptococcus B-hemolytic screening. It is highly effective in preventing the transmission of group B strep from mother to baby during labor and delivery. Administering Penicillin reduces the risk of neonatal sepsis, pneumonia, and meningitis caused by group B strep.
Choice B rationale
Cefazolin is an alternative antibiotic for clients allergic to penicillin. It is less preferred compared to penicillin due to its broader spectrum of activity and potential for resistance. Cefazolin can be used if the client has a non-severe penicillin allergy.
Choice C rationale
Erythromycin is not recommended for group B strep prophylaxis during labor due to its lower efficacy compared to penicillin and cefazolin. It is less effective in preventing neonatal group B strep infections and is used less frequently.
Choice D rationale
Vancomycin is used for clients with a severe penicillin allergy or for those with resistant strains of group B strep. It is a last-resort antibiotic due to its potent effect and potential side effects. It is only used when absolutely necessary.

Correct Answer is B
Explanation
Choice A rationale
Bleeding gums can be common during pregnancy due to increased blood flow and hormonal changes that affect the gums, causing them to be more sensitive and prone to bleeding. It's usually not a cause for immediate concern unless it's severe or accompanied by other symptoms.
Choice B rationale
Abdominal cramping at 26 weeks of gestation could indicate preterm labor or other complications, such as placental abruption. It's a significant symptom that needs immediate medical attention to ensure both maternal and fetal well-being.
Choice C rationale
White vaginal discharge, known as leukorrhea, is common during pregnancy due to increased production of estrogen and greater blood flow to the vaginal area. It helps prevent infections and usually does not indicate a problem unless it has a foul odor or is accompanied by itching or irritation.
Choice D rationale
Asymptomatic palpitations are relatively common during pregnancy due to increased blood volume and changes in circulation. They usually don't indicate a serious problem unless they're severe, persistent, or accompanied by other symptoms like chest pain or shortness of breath.
Correct Answer is A
Explanation
Choice A rationale
Amniocentesis is used to detect fetal genetic abnormalities, such as Down syndrome, by analyzing the amniotic fluid for genetic markers.
Choice B rationale
An empty bladder is required for the test only in late pregnancy to prevent bladder injury; however, in early pregnancy, a full bladder may be required to better visualize the uterus and amniotic fluid.
Choice C rationale
An x-ray is not typically used during the needle placement for amniocentesis. Ultrasound is the preferred method to guide the needle to avoid harm to the fetus and mother.
Choice D rationale
The test does not determine the volume of amniotic fluid; it is used primarily for genetic analysis, assessing fetal lung maturity, and diagnosing certain fetal infections.
