A nurse is caring for a client who had chorionic villus sampling (CVS) performed at 12 weeks’ gestation and asks when she can expect results from this test.

The nurse should inform her that results are typically available within which timeframe?

This is because migraine headaches with aura are a contraindication for receiving oral contraceptives, as they increase the risk of stroke and other cardiovascular complications.

Some possible explanations for the other choices are:

Choice B: A 32-year-old client who has endometriosis.

This is not a contraindication for receiving oral contraceptives, as they can actually help reduce the symptoms of endometriosis by suppressing ovulation and reducing menstrual bleeding.

Choice C: A 28-year-old client who has polycystic ovary syndrome (PCOS).

This is not a contraindication for receiving oral contraceptives, as they can help regulate the menstrual cycle and lower the levels of androgens (male hormones) that cause acne, hirsutism (excess hair growth), and other problems in women with PCOS.

Choice D: A 22-year-old client who has irregular menstrual cycles.

This is not a contraindication for receiving oral contraceptives, as they can help normalize the menstrual cycle and prevent unintended pregnancy.

Normal ranges for oral contraceptive doses are:

Estrogen: 10 to 35 mcg of ethinyl estradiol or estradiol valerate

Progestin: varies depending on the type and brand of oral contraceptive

The correct answer is choice D. The client has a history of placenta previa.

Placenta previa is a condition where the placenta covers all or part of the cervix, blocking the baby’s exit from the uterus.

This can cause severe bleeding during pregnancy and delivery and increase the risk of complications for both the mother and the baby.

Therefore, the nurse should report this condition to the provider before performing an amniocentesis.

Choice A is wrong because having Rh-negative blood type is not a contraindication for amniocentesis.

However, the client may need an injection of Rh immunoglobulin after the procedure to prevent Rh sensitization.

Choice B is wrong because having a history of preterm labor is not a contraindication for amniocentesis.

However, the client may need to be monitored closely for signs of preterm labor after the procedure.

Choice C is wrong because having a history of gestational diabetes is not a contraindication for amniocentesis.

However, the client may need to have their blood glucose levels checked before and after the procedure.

Amniocentesis is a diagnostic procedure that involves removing and testing a small sample of amniotic fluid from the uterus for genetic or chromosomal conditions, such as Down syndrome, Edwards syndrome or Patau syndrome.

It can also be used to diagnose fetal infections, treat excess amniotic fluid, or test fetal lung maturity
