Answer and Explanation

The Correct Answer is B

Choice B rationale:

Tachycardia and a falling blood pressure are classic signs of shock as the body tries to compensate for the decreased blood flow.

Choice C rationale:

Tachypnea and a widening pulse pressure can be signs of shock, but they are not as indicative as tachycardia and a falling blood pressure.

Choice D rationale:

Bradycardia and auscultation of fluid in the base of the lungs are not typically signs of impending shock.

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.
