A client is receiving "Heparin Sodium 25,000 Units in 250 mL 5% Dextrose" IV at 7 mL/hour. The healthcare provider changes the prescription to 900 units/hour. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["9"]
To calculate the new infusion rate in mL/hour for a prescription of 900 units/hour, one must first determine the concentration of the Heparin Sodium solution. The original concentration is 25,000 units in 250 mL, which means there are 100 units per mL. To deliver 900 units/hour, the nurse should program the infusion pump to deliver 9 mL/hour. This is because 900 units divided by the concentration of 100 units/mL equals 9 mL.

Correct Answer is B
Explanation
A. While the length of exposure can be relevant, it is not the most critical factor before starting isoniazid.
B. Isoniazid can cause hepatotoxicity, so a current diagnosis of hepatitis B is crucial to note as it increases the risk of liver damage.
C. A history of intravenous drug abuse is important for overall health assessment but is less critical than current liver disease.
D. Conversion of the PPD test indicates TB exposure, but assessing liver function and potential for hepatotoxicity is more urgent before starting the medication.
