A.

-2.

B.

+1.

C.

0.

D.

-1.

E.

-1.

Answer and Explanation

The Correct Answer is C

Choice A rationale:

Station -2 means the presenting part is 2 cm above the ischial spines. Engagement usually occurs at 0 station.

Choice B rationale:

Station +1 means the presenting part is 1 cm below the ischial spines. This usually occurs during labor, not necessarily at engagement.

Choice C rationale:

Station 0 means the presenting part is at the level of the ischial spines. This is typically when engagement occurs.

Choice D rationale:

Station -1 means the presenting part is 1 cm above the ischial spines. Engagement usually occurs at 0 station.

Correct Answer is C

Explanation

Choice A rationale:

Offering fluids is important to prevent dehydration, but it’s not the priority during the fourth stage of labor.

Choice B rationale:

Encouraging the woman to void can help prevent urinary retention, but it’s not the priority.

Choice C rationale:

Assessing the uterine fundus is the priority during the fourth stage of labor. This is to ensure that the uterus is contracting and to prevent postpartum hemorrhage.

Choice D rationale:

Assisting with perineal care is important for comfort and hygiene, but it’s not the priority.

So, the correct answer is C, assessing the uterine fundus.

Correct Answer is ["20"]

Explanation

  1. Calculate the total units of insulin in the IV bag:

    • The bag contains 150 mL of solution.
    • The concentration is 0.456 units/mL.
    • Total insulin = 150 mL × 0.456 units/mL = 68.4 units.

  2. Determine how long the IV bag will last:

    • The ordered rate is 9 units/hour.
    • Total duration = 68.4 units ÷ 9 units/hour = 7.6 hours.

  3. Calculate the IV pump rate:

    • The total volume of the bag is 150 mL.
    • Pump rate = 150 mL ÷ 7.6 hours = 19.74 mL/hr.
    • Rounded to the nearest whole number: 20 mL/hr.

So the nurse should set the IV pump to 20 mL/hr.
