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

The correct answer is choice D. Presence of human chorionic gonadotropin (hCG) in blood.This is apositive sign of pregnancythat can only be attributed to a fetus.hCG is a hormone produced by the placenta that can be detected in blood or urine tests.

Choice A. Quickening.This is apresumptive sign of pregnancythat is based on the woman’s report of feeling fetal movements in her lower abdomen.This can occur at 16 weeks for second time moms and around 20 weeks for first time moms.However, this sign is not conclusive as other conditions can cause similar sensations.

Choice B. Uterine enlargement.This is aprobable sign of pregnancythat can be observed by the nurse or doctor through palpation.However, this sign does not mean 100% that a baby is growing in the uterus as it can be due to other causes such as fibroids or tumors.

Choice C. Urinary frequency.This is apresumptive sign of pregnancythat is based on the woman’s report of needing to urinate more often than usual.This can be caused by hormonal changes and increased blood volume during pregnancy.However, this sign is not definitive as other conditions such as urinary tract infections or diabetes can also cause frequent urination.

This is because a normal fetal heart rate is between 110 and 160 beats per minute, and the range of 136 to 143 indicates that the fetus is well-oxygenated and not experiencing hypoxia or acidosis. The nurse should reassure the patient and explain that fetal movement may decrease during labor due to the pressure of the contractions on the uterus and the fetus.

Choice A is wrong because asking the patient about alcohol consumption is irrelevant and insensitive.

Alcohol can affect fetal development and growth, but it does not directly affect fetal movement or heart rate.

Choice B is wrong because bloody vaginal discharge, or bloody show, is a normal sign of cervical dilation and effacement during labor.

It does not indicate fetal distress or placental abruption.

Choice D is wrong because explaining the relationship between anxiety and fetal movement does not address the patient’s concern or provide any factual information.

Anxiety can affect maternal perception of fetal movement, but it does not cause fetal movement to decrease.

The nurse should validate the patient’s feelings and provide factual reassurance.
