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.

Explanation
Administer an analgesic: Essential. The client is experiencing sudden, sharp chest pain and appears anxious, which indicates the need for pain management.
Initiate a weight-based continuous heparin infusion: Non-essential. This intervention is related to anticoagulation management and is not indicated for the immediate management of a pneumothorax or pain.
Initiate supplemental oxygen: Essential. The client has a low pulse oximetry reading of 85%, indicating a need for supplemental oxygen to improve oxygenation.
Prepare client for a chest tube insertion: Essential. The chest x-ray shows a right upper lobe pneumothorax, and preparing for chest tube insertion is crucial for managing this condition.
Insert an indwelling urinary catheter: Non-essential. There is no indication from the client's current condition that an indwelling urinary catheter is required.
