The Correct Answer is A

A. 3% sodium chloride is a hypertonic solution used to treat severe hyponatremia by raising the serum sodium levels rapidly.
B. 0.9% sodium chloride is isotonic and would not be sufficient to correct severe hyponatremia as quickly.

Correct Answer is ["18"]

Explanation

To calculate the IV pump setting, first convert the patient's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The patient weighs 195 pounds, which is approximately 88.64 kilograms (195 / 2.2). Next, calculate the total units of Heparin needed per hour by multiplying the patient's weight in kilograms by the dosage ordered: 20 units/kg/hr. So, 88.64 kg * 20 units/kg/hr equals 1,772.8 units/hr. Now, determine how many milliliters per hour this dosage requires. Since the premixed bag contains 25,000 units in 250 ml, there are 100 units per ml (25,000 units / 250 ml). Finally, divide the total units needed per hour by the concentration to find the volume needed per hour: 1,772.8 units/hr / 100 units/ml equals 17.728 ml/hr. Rounded to the nearest whole number, the IV pump should be set to 18 ml/hr.
