Correct Answer is ["24"]
Explanation
To calculate the IV pump rate, you'll need to use the formula: (Ordered amount of medication (units/hr) × Volume of fluid in mL) / Amount of medication in the volume = IV pump rate in mL/hr. For the given scenario, the ordered amount is 1,200 units/hr, the volume of fluid is 500 mL, and the amount of medication in the volume is 25,000 units. Plugging these numbers into the formula gives you: (1,200 units/hr × 500 mL) / 25,000 units = 24 mL/hr. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.
Correct Answer is D
Explanation
A. Heart transplantation is not indicated for atrial flutter; it is reserved for end-stage heart failure or severe cardiac conditions that cannot be managed by other means.
B. Defibrillation is used in emergency situations for life-threatening arrhythmias like ventricular fibrillation, not for atrial flutter.
C. Coronary artery stent placement is used to open blocked coronary arteries, not to treat arrhythmias.
D. Radiofrequency catheter ablation targets and destroys the abnormal conduction pathways causing atrial flutter, providing a more permanent solution when medications are ineffective.
