A nurse is providing care to a pregnant woman in labor.

The woman is in the first stage of labor.

When describing this stage to the client, which event would the nurse identify as the major change occurring during this stage?

Cervical dilation (dilatation).

Fetal movement through the birth canal.

Placental separation.

Regular contractions.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Cervical dilation is the major change occurring during the first stage of labor. This stage begins with the onset of labor and ends when the cervix is fully dilated.

Choice B rationale:

Fetal movement through the birth canal primarily occurs during the second stage of labor, not the first.

Choice C rationale:

Placental separation occurs during the third stage of labor, after the baby is born.

Choice D rationale:

Regular contractions do occur during the first stage of labor, but they are not the major change. The major change is cervical dilation.

Correct Answer is ["B","C","D","E"]

Explanation

Choice A rationale:

The vagina is not part of the true pelvis. It is the canal that leads from the uterus to the exterior of the body.

Choice B rationale:

The pelvic inlet is the upper part of the lesser pelvis where the baby’s head engages during labor. It is part of the true pelvis.

Choice C rationale:

The pelvic outlet is the lower opening of the pelvis. It is part of the true pelvis.

Choice D rationale:

The mid pelvis is the part of the pelvis where the baby turns to get into the right position for birth. It is part of the true pelvis.

Choice E rationale:

The pelvic floor muscles support the pelvic organs and help in the process of childbirth. They are part of the true pelvis.

Choice F rationale:

The cervix is the lower part of the uterus that opens into the vagina. It is not part of the true pelvis. So, the correct answers are B, C, D, and E.

Correct Answer is ["mLs\/hr."]

Explanation

Step 1 is to convert the order from milliunits/minute to units/hour. So, 12 milliunits/minute is equal to 0.72 units/hour. Step 2 is to calculate the total units in the IV bag, which is 20 units. Step 3 is to calculate the total volume of the IV bag, which is 500 mL. Step 4 is to calculate the flow rate. So, (0.72 units/hour ÷ 20 units) × 500 mL = 18 mL/hr. So, the correct flow rate to set on the IV pump is 18 mL/hr.
