A nurse is preparing to administer mirtazapine 45 mg PO to a client. The nurse should identify that this is equivalent to how many g? (Round the answer to the nearest thousandth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.045"]
Rationale:
To solve, convert milligrams (mg) to grams (g) step by step:
Determine the dosage required in mg: 45 mg
Understand the conversion factor: 1 g = 1000 mg
Use the formula:
45/1000= 0.045g
Calculate the weight:
