A nurse is caring for a client who has oligohydramnios and is undergoing a biophysical profile (BPP).

The nurse should expect to see which of the following findings on the ultrasound?

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

A contraction stress test (CST) is a test that simulates labor contractions to see how the baby’s heart rate responds to the stress of uterine contractions.

The biggest risk of the test is that it may cause the pregnant person to go into labor before their due date.

Some possible explanations for the other choices are:

Choice B. Premature rupture of membranes.

This is a condition where the amniotic sac breaks before labor begins.

It can increase the risk of infection and cord prolapse, but it is not a direct complication of CST.

Choice C. Infection.

This is a possible risk of any invasive procedure, but CST is usually done with external fetal monitoring and oxytocin infusion, which do not require breaking the skin or entering the uterus.

Choice D. Bleeding.

This is a potential risk of CST for people who have placenta previa, a condition where the placenta covers the cervix and can detach during contractions.

However, CST is not recommended for people who have placenta previa or other conditions that increase the risk of uterine rupture or bleeding.
