Try Naxlex NCLEX-RN (Free-Trial)

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

Correct Answer is A

Explanation

A. The first priority in this situation is to open the client's airway using the jaw-thrust maneuver. This technique is preferred for clients with suspected spinal injuries to avoid further spinal cord damage. Ensuring the airway is open and providing oxygenation are immediate life-saving actions.
B. Checking cranial nerve function, including assessing pupils, is important for evaluating neurological status but is not the first action when the client is not breathing. Ensuring the airway is open and providing oxygenation is the priority.
C. While placing the client in a rigid cervical collar is important for stabilizing the spine and preventing further injury, it should be done after ensuring the airway is clear. The immediate concern is to address the client's non-breathing status.
D. Evaluating the client for brain injury is important for overall assessment but is secondary to addressing the immediate life threat of not breathing. Ensuring the airway is open and then stabilizing the spine is the priority.
