A nurse in a provider's office is caring for a 20-year-old client who is at 12 weeks of gestation and requests an amniocentesis to determine the sex of the fetus. Which of the following responses should the nurse make?
"You cannot have an amniocentesis until you are at least 35 years of age.".
"We can schedule the procedure for later today if you'd like.".
"This procedure determines if your baby has genetic or congenital disorders.".
"Your provider will schedule a chorionic villus sampling to determine the sex of your baby.".
The Correct Answer is C
Choice A rationale:
The nurse should not tell the client that she cannot have an amniocentesis until she is at least 35 years of age. Age is not the primary factor for determining the eligibility for an amniocentesis. Amniocentesis is typically performed when there is a medical indication, such as advanced maternal age, abnormal prenatal screening, or a family history of genetic disorders.
Choice B rationale:
The nurse should not schedule the amniocentesis for later today without further clarification from the provider. Scheduling medical procedures without the provider's approval is not within the nurse's scope of practice and could lead to potential risks.
Choice C rationale:
This is the correct answer. The nurse should explain to the client that amniocentesis is a procedure used to determine if the baby has genetic or congenital disorders. It involves the extraction of a small amount of amniotic fluid to analyze the fetal cells for genetic abnormalities.
Choice D rationale:
The nurse should not tell the client that her provider will schedule a chorionic villus sampling (CVS) to determine the sex of the baby. CVS is another prenatal diagnostic test, but its primary purpose is to detect genetic disorders early in pregnancy, not to determine the baby's sex.

Correct Answer is A
Explanation
The correct answer is choiceA. Continue to monitor the client.
Choice A rationale:
Early decelerations are typically benign and are caused by fetal head compression during contractions.They usually do not require any specific intervention other than continued monitoring to ensure they remain early decelerations and do not progress to more concerning patterns.
Choice B rationale:
Discontinuing oxytocin is not necessary for early decelerations, as they are not indicative of fetal distress.Oxytocin would be discontinued if there were signs of more severe decelerations or other complications.
Choice C rationale:
Assisting the client to lay on her right side is not specifically required for early decelerations.This position change is more commonly used for variable or late decelerations to improve uteroplacental blood flow.
Choice D rationale:
Administering oxygen at 8 L/min per mask is not needed for early decelerations.Oxygen is typically reserved for situations where there is evidence of fetal hypoxia or distress.
Correct Answer is C
Explanation
The correct answer is c. Ampicillin.
Rationale:
- Group B Streptococcus (GBS) B-hemolyticis a bacterium that can colonize the vagina and rectum of pregnant women.While usually harmless to the mother,it can be passed to the newborn during birth and cause serious infections,including pneumonia,meningitis,and sepsis.
- Ampicillinis thefirst-line antibioticrecommended by the Centers for Disease Control and Prevention (CDC) for theprevention of GBS disease in newborns.It belongs to thepenicillin classof antibiotics,which are highly effective against GBS and generally well-tolerated by pregnant women and newborns.
- Doxycyclineis not recommended for GBS prophylaxis due to its poor penetration into amniotic fluid and potential for causing tooth discoloration and bone development problems in newborns.
- Cefotetanis an alternative option for women with penicillin allergy,but ampicillin is still preferred due to its lower cost and broader spectrum of activity against GBS strains.
- Fluconazoleis an antifungal medication and has no activity against GBS bacteria.
Detailed Rationale for Each Choice:
a. Doxycycline:
- Rationale against:
- Poor penetration into amniotic fluid:Doxycycline does not effectively reach the amniotic sac,where the baby is surrounded,and therefore may not adequately protect the newborn from GBS infection.
- Adverse effects in newborns:Doxycycline can cause tooth discoloration and bone development problems in infants exposed in utero.
b. Cefotetan:
- Rationale for:
- Alternative for penicillin allergy:Cefotetan is a cephalosporin antibiotic effective against GBS and can be used in women with penicillin allergy.
- Rationale against:
- Second-line option:Ampicillin is the preferred choice due to its lower cost and broader spectrum of activity against GBS strains.
c. Ampicillin:
- Rationale for:
- First-line antibiotic:Ampicillin is the CDC-recommended first-line antibiotic for GBS prophylaxis due to its:
- High effectiveness against GBS:Ampicillin has a broad spectrum of activity against GBS strains.
- Good safety profile:Ampicillin is generally well-tolerated by pregnant women and newborns.
- Cost-effectiveness:Ampicillin is a relatively inexpensive antibiotic compared to other options.
- First-line antibiotic:Ampicillin is the CDC-recommended first-line antibiotic for GBS prophylaxis due to its:
d. Fluconazole:
- Rationale against:
- Antifungal medication:Fluconazole is an antifungal medication and has no activity against GBS,which is a bacterium.
