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.)

Answer and Explanation

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

Explanation

A. An ionized calcium level significantly above the reference range can lead to cardiac dysrhythmias and requires immediate attention to assess cardiac function.
B. While urine output and characteristics are important indicators of renal function, cardiac assessment takes priority due to the potential cardiac effects of hypercalcemia.
C. Assessment of deep tendon reflexes is relevant since hypercalcemia can lead to muscle weakness and diminished reflexes. However, this should be done after assessing for any cardiac dysrhythmias.
D. Comparing muscle strength bilaterally is important for assessing neurological integrity but is not the priority when hypercalcemia is suspected.

A. Monitor the amount of drainage from the client's incision. B. Observe both lower extremities for redness and swelling. C. Evaluate the client's ability to use an incentive spirometer. D. Palpate all peripheral pulse points for volume and strength.

Correct Answer is B

Explanation

A. Monitoring incision drainage is important for infection and wound healing but not directly related to the effectiveness of compression devices.
B. Observing both lower extremities for redness and swelling directly assesses the effectiveness of the pneumatic compression devices in preventing deep vein thrombosis (DVT).
C. Evaluating the use of an incentive spirometer is important for respiratory function but unrelated to the compression devices.
D. Palpating peripheral pulse points is useful for circulation assessment but does not specifically evaluate the prevention of DVT, which is the primary purpose of the compression devices.
