Final answer:
The nurse should prepare to administer 0.3 ml of thiamine HCL.
Step-by-step explanation:
To calculate the volume of thiamine HCL that needs to be administered, we can use the following formula:
Volume (ml) = Mass (g) / Concentration (mg/ml)
Given that the healthcare provider prescribes 0.03 grams of thiamine HCL and the concentration of the thiamine injection is 100 mg/ml, we can substitute these values into the formula:
Volume (ml) = 0.03 g / 100 mg/ml
Converting grams to milligrams: 0.03 g = 30 mg
Volume (ml) = 30 mg / 100 mg/ml = 0.3 ml
Therefore, the nurse should prepare to administer 0.3 ml of thiamine HCL.
