The nurse is caring for a client who is having chest pain. The healthcare provider prescribes an infusion of nitroglycerin. The initial dose is 12 mcg/min. The nitroglycerin is dispensed at a concentration of 100 mg/ 250 mL. How many mL/hr will the nurse set the infusion pump? (Round rate to the nearest tenth. Only enter numbers and decimals. Do not enter any letters in your answer.)

Answer and Explanation

The Correct Answer is ["1.8"]

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

Explanation

Sodium level: The client's sodium level is significantly elevated (157 mEq/L), indicating hyponatremia. This is a critical finding that needs to be addressed promptly to prevent serious complications such as seizures and coma.

Heart rate: While the heart rate is slightly elevated, it is not as urgent a concern as the sodium level. Once the sodium level is stabilized, the nurse can address the heart rate if it remains elevated.
