When a client reports using cocaine during her current pregnancy, which laboratory study should a nurse anticipate?

Urine estriol levels.

Serum bilirubin levels.

Urine toxicology studies.

Lecithin-sphingomyelin ratio.

Answer and Explanation

The Correct Answer is C

This is because urine toxicology studies can detect the presence of cocaine and other drugs in the body of the pregnant woman and her unborn baby. Cocaine use during pregnancy can have serious consequences for both the mother and the baby, such as high blood pressure, premature labor, low birth weight, and developmental problems.

Choice A is wrong because urine estriol levels are used to measure the activity of the placenta and the fetal adrenal glands. They are not related to cocaine use.

Choice B is wrong because serum bilirubin levels are used to assess the liver function and the risk of jaundice in newborns. They are not related to cocaine use.

Choice D is wrong because lecithin-sphingomyelin ratio is used to evaluate the fetal lung maturity and the risk of respiratory distress syndrome. It is not related to cocaine use.

Correct Answer is D

Explanation

This is because epidural anesthesia can cause hypotension (low blood pressure) which can affect the placental blood flow and fetal oxygenation.

The nurse should monitor the patient’s blood pressure frequently and intervene if it drops below the baseline.

Choice A is wrong because assessing the patient’s urine for acetone is not relevant to the side effects of epidural anesthesia.Acetone in urine can indicate diabetic ketoacidosis, a complication of diabetes that occurs when the body breaks down fat for energy due to lack of insulin.

However, this is not related to epidural anesthesia.

Choice B is wrong because monitoring the patient’s deep tendon reflexes is not relevant to the side effects of epidural anesthesia.Deep tendon reflexes can be affected by magnesium sulfate, a medication used to prevent seizures in patients with preeclampsia (a condition characterized by high blood pressure and proteinuria in pregnancy).

However, this is not related to epidural anesthesia.

Choice C is wrong because assessing the patient’s pupillary accommodation is not relevant to the side effects of epidural anesthesia.

Pupillary accommodation is the ability of the eye to adjust its focus from distant to near objects.It can be impaired by drugs that affect the nervous system, such as opioids or anticholinergics.

A. Plan to remain flat in bed for six hours after the test. B. Expect some vaginal bleeding after the test. C. Empty your bladder prior to the test. D. Do not consume any solid foods for sixteen hours prior to the test.

Correct Answer is C

Explanation

The correct answer is choice C. Empty your bladder prior to the test.This is because a full bladder can interfere with the insertion of the needle and increase the risk of complications.Amniocentesis is a test that involves removing and testing a small sample of cells from amniotic fluid, the fluid that surrounds the baby in the womb.It is done to check for genetic or chromosomal conditions, such as Down’s syndrome, Edwards’ syndrome or Patau’s syndrome.

Choice A is wrong because there is no need to remain flat in bed for six hours after the test.You can resume your normal activities after a few hours of rest.

Choice B is wrong because vaginal bleeding is not a normal outcome of amniocentesis.If you experience any bleeding, leaking of fluid, fever or severe pain after the test, you should contact your doctor immediately.

Choice D is wrong because there is no restriction on eating before the test.You can have your normal meals and drinks before amniocentesis.
