A nurse is admitting a patient to the birthing unit who reports her contractions started 1 hour ago. The nurse determines the patient is 80% effaced and 8 cm dilated.The nurse realizes that the patient is at risk for which of the following conditions?

Choice A rationale
A pudendal nerve block is not typically used for postpartum perineal pain management. It is more commonly used during labor to relieve pain in the perineum and vagina.
Choice B rationale
While hydrogel pads can provide cooling relief, they are not typically used for third-degree perineal lacerations. These types of lacerations often require more intensive interventions.
Choice C rationale

Applying a warm pack to the perineum can help with discomfort, but it is not the primary intervention for a third-degree perineal laceration.
Choice D rationale
Witch hazel pads are often recommended for postpartum perineal care. They can provide relief from soreness, reduce inflammation, and promote healing.

Choice A rationale
Chorionic villus sampling (CVS) is a prenatal test that diagnoses chromosomal abnormalities such as Down syndrome, as well as a host of other genetic disorders. While it can determine the sex of the baby, it is not typically used for this purpose.

Choice B rationale
The statement that one cannot have an amniocentesis until they are at least 35 years of age is incorrect. While it is true that amniocentesis is often offered to women over the age of 35 due to an increased risk of chromosomal abnormalities, it can be performed on anyone at risk, regardless of age.
Choice C rationale
Scheduling the procedure for later in the day is not typically how amniocentesis is planned. It is a medical procedure that requires careful planning and preparation. It is usually performed between the 15th and 20th weeks of pregnancy.
Choice D rationale
This is the correct answer. Amniocentesis is a prenatal test that allows doctors to diagnose a range of genetic and chromosomal disorders. It involves taking a small sample of the amniotic fluid that surrounds the baby in the uterus for testing. The procedure can indeed determine if the baby has genetic or congenital disorders.
