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 A
Explanation
A. Digoxin is a positive inotropic agent, meaning it increases the force of cardiac contractions. This helps improve cardiac output in patients with heart failure.
B. Digoxin does not decrease the force of contractions; instead, it strengthens them, making it beneficial for heart failure treatment.
C. Digoxin is commonly used in heart failure management, particularly in cases of systolic dysfunction or atrial fibrillation.
D. Digoxin decreases heart rate by slowing conduction through the atrioventricular (AV) node, making it useful in atrial fibrillation, but its primary benefit in heart failure is increasing contractility.
Correct Answer is D
Explanation
A. Muffled heart sounds are associated with pericardial effusion or tamponade, not infective endocarditis.
B. Palpitations can occur but are not a classic sign of infective endocarditis.
C. Hives suggest an allergic reaction, not endocarditis.
D. Splinter hemorrhages (tiny, red-brown streaks under the nails) are a classic sign of infective endocarditis due to small emboli from the infected heart valves.
