A nurse is caring for a client who is in the first stage of labor, undergoing external fetal monitoring, and receiving IV fluid. The nurse observes variable decelerations in the fetal heart rate on the monitor strip. Which of the following is a correct interpretation of this finding?

A.

Variable decelerations are a result of the administration of IV narcotic analgesics.

B.

Variable decelerations are related to fetal head compression.

C.

Variable decelerations are due to umbilical cord compression.

D.

Variable decelerations are caused by uteroplacental insufficiency.

Answer and Explanation

The Correct Answer is C

A)    Variable decelerations are a result of the administration of IV narcotic analgesics: IV narcotic analgesics can cause changes in the fetal heart rate, but they are more commonly associated with early decelerations, not variable decelerations.
 
B)    Variable decelerations are related to fetal head compression: Fetal head compression is associated with early decelerations, not variable decelerations.
C)    Variable decelerations are due to umbilical cord compression: This is the correct answer.

Variable decelerations occur due to compression of the umbilical cord during contractions, leading to transient decreases in fetal blood flow and oxygenation.
D)    Variable decelerations are caused by uteroplacental insufficiency: Uteroplacental insufficiency is associated with late decelerations, not variable decelerations.

Correct Answer is B

Explanation

Choice A: Bowel prep protocols are not required for an amniocentesis procedure, as it involves sampling amniotic fluid from the uterus, not the bowel.
Choice B: Emptying the bladder before the procedure is important to improve comfort and minimize the risk of accidental puncture during the amniocentesis.

Choice C: It is essential to have a full bladder for some ultrasound procedures, but it is not necessary for an amniocentesis. A full bladder can help push the uterus upward and make it easier to visualize the fetus during the ultrasound, but it is not relevant to the amniocentesis procedure.
Choice D: Washing the abdomen with soap and water is not a required step for an amniocentesis procedure. The procedure involves sterile preparation of the abdomen using an antiseptic
solution.

Correct Answer is D

Explanation

A) "It is used to treat genital herpes simplex virus.": This statement is incorrect. Dinoprostone (Cervidil) gel is not used to treat genital herpes simplex virus; it is used in obstetrics to ripen the cervix and prepare it for labor induction.
B) "This medicine causes relaxation of the uterine muscles.": While dinoprostone is a prostaglandin that can induce uterine contractions, its primary use in this context is cervical ripening, not uterine muscle relaxation.
C) "This medication is used to treat preeclampsia.": Dinoprostone is not used to treat preeclampsia. It is used for cervical ripening and labor induction in appropriate situations.
D) "This medication is used to ripen, or soften, the cervix.": This is the correct answer. Dinoprostone (Cervidil) gel is used to ripen the cervix, making it more favorable for labor induction, especially in cases where the cervix is not yet fully dilated or effaced.
