Question

A client returns from the PACU with a bag of IV fluids that has 630 mL remaining in the 1,000 mL bag. The prescription reads, "Continue the present IV over the next 7 hours." The IV administration set delivers 10 gtt/mL. The nurse should regulate the infusion to deliver how many drops/minute to accomplish the new prescription? (Enter numeric value only)

Answer 1

Correct Answers:

15

Rationale :

Volume to infuse = 630 mL over 7 hrs = 90 mL/hr Drop factor = 10 gtt/mL Use formula: 90×1060=15 gtt/min\frac{90 \times 10}{60} = 15 \text{ gtt/min}6090×10=15 gtt/min This regulates the flow rate to ensure the prescribed infusion time.

Answer 2

Correct Answers:

168

Rationale :

Weight in kg = 1852.2=84.1 kg\frac{185}{2.2} = 84.1 \text{ kg}2.2185=84.1 kg Dose = 2 mg/kg → 84.1×2=168.2≈168 mg84.1 \times 2 = 168.2 \approx 168 \text{ mg}84.1×2=168.2≈168 mg Zidovudine dose must match the client’s body weight accurately to prevent toxicity.

Answer 3

Correct Answers:

18

Rationale :

20,000 units in 250 mL → Concentration = 80 units/mL Required: 1,400 units/hr → 140080=17.5≈18 mL/hr\frac{1400}{80} = 17.5 \approx 18 \text{ mL/hr}801400=17.5≈18 mL/hr This calculation ensures safe and effective heparin delivery.

Answer 4

Correct Answers:

0.5

Rationale :

Weight = 132 lb → 132÷2.2=60 kg132 ÷ 2.2 = 60 \text{ kg}132÷2.2=60 kg Dose = 5 mcg/kg → 60×5=300 mcg60 × 5 = 300 \text{ mcg}60×5=300 mcg Available: 480 mcg/0.8 mL → 300480×0.8=0.5 mL\frac{300}{480} × 0.8 = 0.5 \text{ mL}480300×0.8=0.5 mL Filgrastim dose must be weight-based to promote safe white blood cell growth.

Correct Answers:

400

Rationale :

1,000 mL over 2.5 hrs → 10002.5=400 mL/hr\frac{1000}{2.5} = 400 \text{ mL/hr}2.51000=400 mL/hr The infusion rate ensures timely hydration in renal calculi treatment.

Answer 6

Correct Answers:

2

Rationale :

10 mg ordered; concentration = 5 mg/5 mL → 10 mg = 10 mL Since 1 tsp = 5 mL → 105=2 teaspoons\frac{10}{5} = 2 \text{ teaspoons}510=2 teaspoons This ensures accurate patient self-administration.

Answer 9

Correct Answers:

600

Rationale :

🟠 Volume = 200 mL 🟠 Time = 20 minutes = 0.33 hrs 🟠 2000.33≈600 mL/hr\frac{200}{0.33} \approx 600 \text{ mL/hr}0.33200≈600 mL/hr 🟠 High rate needed for rapid bolus administration.

Answer 10

Correct Answers:

1.2

Rationale :

🔴 Weight = 132 lb → 60 kg 🔴 1 mg/kg = 60 mg → 2 doses/day = 120 mg/day 🔴 Syringe = 60 mg/0.6 mL → 1 dose = 0.6 mL 🔴 Total daily = 0.6 mL × 2 = 1.2 mL
