Question 1 of 5
A nurse is preparing to administer hydrocortisone sodium succinate 250 mg via IV bolus every 6 hr. Available is hydrocortisone sodium succinate 1000 mg/8 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: B
Rationale:
To calculate the mL to administer, use the formula: Desired dose (250 mg) x Volume available (8 mL) / Stock dose (1000 mg) = X mL. Substituting the values, we get 250 x 8 / 1000 = 2.
Therefore, the nurse should administer 2 mL. Option B is correct. Option A (1 mL) is too low as it would be less than the required dose. Option C (3 mL) and Option D (4 mL) are too high as they exceed the required dose.
