A patient weighing 60 kg is prescribed intravenous dopamine 4 micrograms/kg/minute. Calculate the infusion rate in mL/hour. (Stock = dopamine 200 mg in 50 mL glucose 5%).

$$\text{Dose per hour} = 240 \frac{\mu\text{g}}{\text{min}} \times \frac{1\text{ mg}}{1000\text{ }\mu\text{g}} \times \frac{60\text{ min}}{1\text{ hr}}$$ $$\text{Dose per hour} = \frac{240 \times 60}{1000} \frac{\text{mg}}{\text{hr}} = \frac{14400}{1000} \frac{\text{mg}}{\text{hr}} = 14.4 \frac{\text{mg}}{\text{hr}}$$

$$\text{Infusion rate} = \frac{\text{Dose per hour}}{\text{Concentration}} = \frac{14.4 \frac{\text{mg}}{\text{hr}}}{4 \frac{\text{mg}}{\text{mL}}}$$ $$\text{Infusion rate} = 3.6 \frac{\text{mL}}{\text{hr}}$$

The correct option is B.
The infusion rate is $\boxed{\textbf{3.6 mL/hour}}$.

5. The procedure which is used to prove that the various production procedures, equipment and materials will produce accurate results is known as:

The correct option is D.

• Validation is the documented act of proving that any procedure, process, equipment, material, activity, or system actually leads to the expected results. This directly matches the description of proving that production procedures, equipment, and materials will produce accurate results.

The correct answer is $\boxed{\textbf{D. Validation}}$.
