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

Explanation

Choice A rationale:

This choice indicates 3 pregnancies, 1 term, 2 preterm, 2 living children, and 3 abortions. However, the client has had 4 pregnancies (twins, a son, and a miscarriage), so this choice is incorrect.

Choice B rationale:

This choice indicates 3 pregnancies, 2 term, 1 preterm, no living children, and 3 abortions. The client has 3 living children (twins and a son), so this choice is incorrect.

Choice C rationale:

This choice indicates 4 pregnancies, 1 term, 1 preterm, 1 living child, and 3 abortions. The client has 3 living children (twins and a son), so this choice is incorrect.

Choice D rationale:

This choice indicates 4 pregnancies, 2 term, 1 preterm, 3 living children, and 1 abortion. This correctly reflects the client’s obstetric history.

Correct Answer is B

Explanation

Choice A rationale:

Bacterial vaginosis typically presents with a thin, grayish-white discharge with a fishy odor. It does not usually cause intense itching or dyspareunia.

Choice B rationale:

Candidiasis is characterized by a thick, white, cottage cheese-like vaginal discharge, intense itching, and dyspareunia. These symptoms align with the client’s presentation.

Choice C rationale:

Genital herpes simplex usually presents with painful blisters or ulcers in the genital area, not a thick, white discharge.

Choice D rationale:

Trichomoniasis often causes a frothy, yellow-green discharge with a fishy smell. Itching can occur, but the discharge is not typically thick and white.
