1 : A nurse is preparing to administer cefazolin IVPB over 20 min.Available is cefazolin 1 g in 100 mL of dextrose 5% in water (D5W). The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.Use a leading zero if it applies.Do not use a trailing zero.)

Hint : Use the formula: (Volume × Drop factor) ÷ Minutes

Correct Answers:

Rationale :

✅Flow rate = (Volume × Drop factor) ÷ Time (in minutes) = (100 × 15) ÷ 20 = 1500 ÷ 20 = 75 gtt/min

Distractor Analysis :

Rationale for Incorrect Options to be Available Soon

2 : A nurse is providing discharge teaching to the parent of a child who is prescribed diphenhydramine 25 mg elixir every 4 hr as needed. The amount available is diphenhydramine elixir 125 mg/5 mL. How many mL should the nurse administer per dose?(Round the answer to the nearest tenth.Use a leading zero if it applies.Do not use a trailing zero.)

Hint : Convert mg to mL using the concentration ratio.

Correct Answers:

Rationale :

✅To calculate the volume per dose: 👉25mg/125mg×5mL=1mL ♦️Thus, the nurse will administer 1 mL per dose.

Distractor Analysis :

Rationale for Incorrect Options to be Available Soon

3 : A nurse is preparing to administer dextrose 5% in water (D5W) 150 mL IV to infuse over 3 hr. The drop factor of the IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number.Use a leading zero if it applies.Do not use a trailing zero.) 8gt/min

Hint : Always convert hours to minutes before calculating drip rates.

Correct Answers:

Rationale :

👉Total minutes: 3 hours = 180 minutes ✅(150 mL×10 gtt/mL)÷180=1500÷180=8.3≈8 gtt/min ♦️Rounding gives the correct drip rate for accurate administration.

4 : A nurse is preparing to administer 3000 units of drugX. Available is drug X, 5000 units/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth.Use a leading zero if it applies.Do not use a trailing zero.

Hint : Dose ÷ Concentration = Volume to give

Correct Answers:

Rationale :

✅3000 units÷5000 units/mL=0.6 mL ♦️This provides the correct volume for the desired dosage.

5 : A nurse is preparing to administer amoxicillin 2 gm/day PO divided into two doses. The amount available is amoxicillin 500 mg tablets .How many tablets should the nurse administer with each dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Convert grams to mg, then divide by tablet strength.

Correct Answers:

Rationale :

🎯Total daily dose: 2000 mg. 🎯2000 ÷ 2 = 1000 mg per dose 📌1000 ÷ 500 mg/tablet = 2 tablets per dose

6 : A nurse is administering RBC 350 mL over 3 hr to a client who has anemia.

The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) 117ml/hr

Hint : Total volume ÷ total time = mL/hr for pump settings.

Correct Answers:

Rationale :

📌350 mL÷3 hr=116.6≈117 mL/hr 🎯This setting ensures even RBC infusion over 3 hours.

Distractor Analysis :

Rationale for Incorrect Options to be Available Soon

7 : A nurse is preparing to administer hydrocortisone sodium succinate 250 mg via IV bolus every 6 hr. Available is hydrocortisone sodium succinate 1000 mg/8 mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) 2ml

Hint : Always apply (Desired ÷ Available) × Volume

Correct Answers:

Rationale :

📌(250÷1000)×8=2 mL 🎯This delivers the accurate dose of hydrocortisone based on concentration.

Distractor Analysis :

Rationale for Incorrect Options to be Available Soon

8 : A nurse is preparing to administer 0.45% sodium chloride solution 1000 mL IV to infuse over 8 hr. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hint : Basic pump rate = Volume ÷ Time

Correct Answers:

Rationale :

📌1000 mL÷8 hr=125 mL/hr 🎯This is a standard infusion rate for IV fluids over 8 hours.

Distractor Analysis :

Rationale for Incorrect Options to be Available Soon

9 : A provider prescribes dextrose 5% in water (D5W) IV to infuse at 100 mL/hr. The drop factor on the IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number.)

Hint : For 60 gtt/mL tubing, the number of mL/hr = gtt/min

Correct Answers:

Rationale :

📌With a microdrip (60 gtt/mL), mL/hr = gtt/min 🎯100 mL/hr=100 gtt/min

Distractor Analysis :

Rationale for Incorrect Options to be Available Soon

10 : A nurse is preparing to infuse 1 liter of 0.99% sodium chloride IV over 8 hr with a tubing set that delivers 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many drops/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) .

Hint : Convert hours to minutes before plug-in.

Correct Answers:

Rationale :

📌(1000×15)÷480=31.25≈31 gtt/min 🎯8 hr = 480 minutes
