A Nurse is preparing to start a heparin drip on a client with acute coronary syndrome. Ordered: Give Heparin 1000 units per hour, standard dilution of 25,000 units in 250 mL of normal saline. What is the correct drip setting for the pump in mL/hr?
The Correct Answer is ["10"]
- Determine the heparin concentration:
- You have 25,000 units of heparin in 250 mL of normal saline.
- Concentration = 25,000 units / 250 mL = 100 units/mL
- Calculate the mL/hr rate:
- The order is for 1,000 units/hour.
- Drip rate (mL/hr) = 1,000 units/hour / 100 units/mL = 10 mL/hour
Answer = 10mL/hr

Correct Answer is B
Explanation
A. Lidocaine is used for ventricular arrhythmias, not supraventricular tachycardia (SVT).
B. Adenosine is the first-line treatment for stable SVT, as it temporarily blocks AV node conduction, allowing the heart to reset into a normal rhythm. It is given as a rapid IV push.
C. Atropine increases heart rate and is used for bradycardia, not tachycardia.
D. Epinephrine stimulates the heart and is used for asystole and severe bradycardia, not SVT.
Correct Answer is C
Explanation
A. Hypertensive crisis is not a direct complication of atrial fibrillation. It is typically caused by uncontrolled hypertension rather than arrhythmias.
B. Cardiogenic shock can occur in severe heart failure but is not a primary complication of atrial fibrillation.
C. Embolic cerebral vascular accident (stroke) is a major risk for clients with atrial fibrillation. The irregular atrial contractions allow blood to pool in the atria, increasing the risk of clot formation. If a clot dislodges, it can travel to the brain and cause a stroke.
D. Flash pulmonary edema is a complication of acute decompensated heart failure but is not directly caused by atrial fibrillation.
