The nurse is caring for a client who has disseminated intravascular coagulation (DIC). The healthcare provider prescribes an infusion of heparin. Based on the protocol, the initial dose is 14 units/kg/hr. The heparin is dispensed at a concentration of 25,000 units/250 ml. The client weighs 79.1 kg. How many mL/hr will the nurse set the Infusion pump? (Round the rate to nearest tenth. Only enter numbers and decimals. Do not enter any letters in your answer.)
Answer and Explanation

The Correct Answer is ["11.074"]

To calculate the infusion rate, we'll use the following formula:

Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of heparin (units/mL)

First, calculate the desired dose in units/hr:

  • 14 units/kg/hr x 79.1 kg = 1107.4 units/hr

Next, calculate the concentration of heparin in the IV bag:

  • 25,000 units / 250 mL = 100 units/mL

Finally, plug the values into the formula:

  • Infusion rate = 1107.4 units/hr / 100 units/mL = 11.074 mL/hr

Correct Answer is ["1.8"]

Explanation

Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of nitroglycerin (units/mL)

First, calculate the concentration of nitroglycerin in the IV bag:

  • 100 mg / 250 mL = 0.4 mg/mL

Next, convert the desired dose from mcg/min to mg/hr:

  • 12 mcg/min 60 min/hr = 720 mcg/hr = 0.72 mg/hr

Finally, plug the values into the formula:

  • Infusion rate = 0.72 mg/hr / 0.4 mg/mL = 1.8 mL/hr

Correct Answer is C

Explanation

A. Using a portable electronic thermometer is incorrect as the device must be dedicated to the client to avoid cross-contamination.
B. Wiping the stethoscope with alcohol after use is insufficient because alcohol-based sanitizers are ineffective against C. difficile spores. The stethoscope should be cleaned with bleach-based disinfectant.
C. Removing the protective gown before leaving the client's room is correct as it prevents the spread of C. difficile spores outside the isolation area.
D. Removing the protective gown before removing gloves is incorrect. Gloves should be removed first to prevent contamination when removing the gown.
