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 {"A":{"answers":"C"},"B":{"answers":"B"},"C":{"answers":"B"},"D":{"answers":"B"},"E":{"answers":"A"}}
Explanation
A. Teach the client how to count carbohydrates - Non-urgent. While essential for long- term management of diabetes, carbohydrate counting is not immediately critical in the acute management phase of HHS in the ICU. This teaching should be delayed until the patient is stabilized.
B. Stop the insulin infusion - Contraindicated. Stopping insulin in a patient with HHS, which is characterized by severe hyperglycemia, would be harmful. Insulin therapy is critical to reduce blood glucose levels safely.
C. Decrease the frequency of blood glucose tests - Contraindicated. Frequent monitoring is crucial in managing HHS, especially when insulin therapy is being administered, to prevent hypoglycemia and to monitor the effectiveness of treatment.
D. Start the client on a regular diet - Contraindicated. Introducing a regular diet during the acute phase of HHS could exacerbate the hyperglycemia. Nutritional needs should be assessed and managed carefully, typically starting with IV fluids and gradually transitioning to enteral or oral feeding as the patient stabilizes.
E. Decrease the insulin IV infusion to 0.05 units/kg/hr- Indicated. As blood sugar levels decrease, the insulin infusion rate may be cautiously reduced to prevent hypoglycemia.
Correct Answer is D
Explanation
A. Pink-tinged hematuria is expected after the procedure, but reporting should be directed at increased bleeding or other signs of complications.
B. While some activity restrictions are necessary, a complete restriction of all physical activities is generally not advised and can lead to other complications like blood clots or decreased mobility.
C. An incentive spirometer is typically used to prevent respiratory complications post-surgery, but it is not specifically related to nephrolithotomy procedures.
D. Monitoring the urinary output is crucial because decreased output can indicate a blockage or other complications related to the nephrostomy tube.
