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.
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 B
Explanation
The correct answer is choice B. “You are doing a great job.
It’s very difficult to support someone during this part of labor.” This response acknowledges the husband’s feelings and efforts, and provides reassurance and encouragement.
It also reflects the reality that active labor can be very intense and painful for the woman, and she may not want to be touched or talked to.
Choice A is wrong because it suggests that the husband is not needed or wanted, and may make him feel rejected or useless.
Choice C is wrong because it implies that the husband is not a good support person, and may hurt his self-esteem or damage his relationship with his wife.
Choice D is wrong because it focuses on the physical aspect of labor, rather than the emotional one.
It also assumes that the woman wants medication, which may not be the case.
Correct Answer is B
Explanation
The correct answer is choice B. Insulin amount needs will continue to increase throughout the second and third trimesters.This is because gestational diabetes is a form of diabetes that develops during pregnancy, usually during the 2nd or 3rd trimester.It is caused by hormonal changes that interfere with the action of insulin, leading to high blood sugar levels.As the pregnancy progresses, the placenta produces more hormones that increase insulin resistance, so the mother needs more insulin to keep her blood sugar within normal range.
Choice A is wrong because insulin amount needs will not remain stable during the third trimester.They will increase as the placenta grows and produces more hormones that cause insulin resistance.
Choice C is wrong because insulin amount needs will not decrease during the third trimester.They will increase as the placenta grows and produces more hormones that cause insulin resistance.
Choice D is wrong because insulin amount needs will not remain stable for the rest of the second and during the third trimesters.They will increase as the pregnancy progresses and the placenta produces more hormones that increase insulin resistance.
Normal ranges for blood sugar during pregnancy are: fasting < 95 mg/dL, 1 hour after meal < 140 mg/dL, 2 hours after meal < 120 mg/dL.
