A nurse is caring for a client is who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 mL D5W. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["24"]
- First, determine the concentration of the heparin solution. In this case, it's 25,000 units in 500 mL, which means there are 50 units per mL.
- Next, calculate the required rate to deliver 1,200 units per hour. Since the concentration is 50 units per mL, divide 1,200 units by 50 units/mL to find the required mL per hour.
- The calculation will be 1,200 units/hr ÷ 50 units/mL = 24 mL/hr.
- Since the question asks to round to the nearest tenth or whole number, and the result is a whole number, the IV pump should be set to deliver 24.0 mL/hr.

Correct Answer is ["100"]
Explanation
- First, determine the total volume to be infused: 50 mL.
- Next, calculate the time in hours: 30 minutes is 0.5 hours.
50/0.5
= 100mL/hr
Correct Answer is []
Explanation
Condition:
A. Transfusion-associated circulatory overload (TACO)
Rationale: The client’s symptoms—dyspnea, restlessness, crackles in the lungs, jugular vein distension, and elevated blood pressure—are consistent with TACO, a condition resulting from excessive fluid volume during a blood transfusion.
Actions to Take:
C. Administer furosemide
Rationale: Furosemide is a diuretic that helps reduce fluid overload, which is a key issue in TACO.
B. Administer diphenhydramine
Rationale: Although not the primary treatment for TACO, diphenhydramine can help manage symptoms if there is a mild allergic reaction contributing to the situation.
Parameters to Monitor:
A. Intake and output
Rationale: Monitoring intake and output helps assess fluid balance and effectiveness of treatment for TACO.
D. Weight
Rationale: Weight monitoring helps assess fluid overload and effectiveness of diuretic therapy
