The pharmacy sends a bag of 150 mLs of D5W/0.456 normal saline with 25 units of Regular Insulin.

The patient is ordered to receive an insulin drip at a rate of 9 units/hour.

What rate will you set the IV pump to deliver? Numeric values only.
Answer and Explanation

The Correct Answer is ["20"]

  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.

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

Explanation

Choice A rationale:

Cervical effacement of 30% is more indicative of the early phase of labor, not the active phase. In the active phase, effacement is usually 80-100%.

Choice B rationale:

A strong desire to push is usually associated with the transition phase of labor, not the active phase.

Choice C rationale:

Contractions every 90 seconds could be indicative of the active phase, but this can vary between individuals.

Choice D rationale:

Cervical dilation of 6 cm is indeed indicative of the active phase of labor, which is typically characterized by cervical dilation of 4-7 cm.

Choice E rationale:

Contractions every 2 to 3 minutes are common in the active phase of labor.

Correct Answer is A

Explanation

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.
