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.)

Answer and Explanation

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.

Answer =24

A. Side-lying B. Supine C. High-Fowler's D. Leaning forward

Correct Answer is C

Explanation

A. The side-lying position is not appropriate for paracentesis because it does not allow optimal access to the abdomen and can make fluid removal more difficult.

B. The supine position is also not suitable for paracentesis, as it may not allow for proper drainage and can increase the risk of respiratory compromise, especially in clients with large volumes of ascitic fluid.

C. High-Fowler’s position is correct because it helps pool the ascitic fluid in the lower abdomen, making it easier to access and drain during the procedure. This position also helps improve breathing by relieving pressure on the diaphragm caused by the ascites.

D. The leaning forward position is not appropriate for paracentesis, as it can be uncomfortable and does not provide optimal access to the abdominal cavity for fluid removal.
