Question 1 of 5
A child is to receive atropine 0.15 mg (1/400 g) as part of his preoperative medication. A vial containing atropine 0.4 mg (1/150 g)/mL is on hand. How much atropine should be given?
Correct Answer: B
Rationale: The answer is correct. 0.4 mg = 1 mL : 0.15 mg = x mL, 0.4x = 0.15, x = 0.15 / 0.4, x = 0.375 or 0.38 mL. Sufficient information is provided to determine the amount of atropine to administer. The amount of atropine available and the amount of atropine ordered is required to determine the amount of atropine to be given.
