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 C

Explanation

Choice A rationale:

This statement emphasizes the importance of health over time, which is true. However, it doesn’t directly answer the woman’s question about the duration of labor.

Choice B rationale:

The size of the baby can influence labor duration, but it’s not the only factor. Other factors like the woman’s health, age, and labor progression also matter.

Choice C rationale:

This response is supportive and honest. It acknowledges the unpredictability of labor while assuring the woman of continuous support.

Choice D rationale:

While it’s true that first-time mothers may have longer labors, predicting a specific duration like 10 hours isn’t accurate or helpful.

Correct Answer is B

Explanation

Swallowing a preprocedure sedative is not typically required for an amniocentesis. Sedatives can affect the mother and the fetus, and are usually avoided unless absolutely necessary.

Choice B rationale:

Emptying the bladder is important before an amniocentesis. A full bladder can push against the uterus, increasing the risk of puncturing the bladder during the procedure.

Choice C rationale:

Showering with an antiseptic scrub is not typically required before an amniocentesis. The area of the abdomen where the needle will be inserted is usually cleaned with an antiseptic by the healthcare provider.

Choice D rationale:

Lying on the left side is not typically required for an amniocentesis. The procedure is usually performed with the woman lying on her back.
