Question 1

Calculate IV rates for medications administered over time. Set the rate in mL/hr. Round answers to the nearest tenth.
-Pronestyl 4 g in 1000 mL D₅W. Infuse at 2½ mg/min.

Accepted Answer

$\frac{2.5 \mathrm{mg}}{\min } \times \frac{1 \mathrm{~g}}{1000 \mathrm{mg}} \times \frac{1000 \mathrm{~mL}}{4 \mathrm{~g}} \times \frac{60 \mathrm{~min}}{1 \mathrm{hr}}=\frac{150,000}{4000}=\frac{37.75 \mathrm{~mL}}{\mathrm{hr}}$

Question 2

Calculate IV rates for medications administered over time, based on body weight. Round answers to the nearest tenth. Set the rate in mL/hr.
-Ordered: Infuse nitroprusside 100 mg in 500 mL D₅W at 3 mcg/kg/min. Patient weighs 55 kg.

Accepted Answer

$\frac{55 \mathrm{~kg}}{1} \times \frac{3 \mathrm{mcg}}{\mathrm{kg} / \mathrm{min}} \times \frac{1 \mathrm{mg}}{1000 \mathrm{mcg}} \times \frac{500 \mathrm{~mL}}{100 \mathrm{mg}} \times \frac{60 \mathrm{~min}}{1 \mathrm{hr}}=\frac{49,500}{1000}=\frac{49.5 \mathrm{~mL}}{\mathrm{hr}}$

Question 3

Calculate small volumes to be infused in less than 1 hour in gtt/min.
-Tagamet 200 mg in D₅W 100 mL over 20 minutes. Drop factor is 15 gtt/mL.

Accepted Answer

$\frac{100 \mathrm{~mL}}{20 \mathrm{~min}} \times \frac{15 \mathrm{gtt}}{1 \mathrm{~mL}}=\frac{1500}{20}=\frac{75 \mathrm{gtt}}{\mathrm{min}}$
