Question

The client has an order for Lactated Ringers 600 mL to infuse over 5 hours. At what rate will the nurse set the infusion? 1 mL/hr (If needed, round to the nearest whole number.)

Answer 1

Correct Answers:

120

Rationale :

🧮Lactated Ringer's solution is an isotonic IV fluid commonly used to replace fluids and electrolytes in patients with dehydration or during surgery.

🕒To determine the infusion rate in mL/hr, divide the total volume (600 mL) by the infusion time (5 hours).

📏This yields 600 ÷ 5 = 120 mL/hr, which is the rate that ensures the fluid is evenly distributed over the prescribed time.

✅Setting the IV pump to 120 mL/hr promotes accurate fluid balance and avoids under- or overhydration complications.

📌Core message

Always divide total volume by time to calculate the correct IV infusion rate in mL/hr.

Answer 2

Correct Answers:

0.3

Rationale :

🧮To determine volume for administration, use the formula: Dose ÷ Stock = Volume (60 mcg ÷ 200 mcg/mL = 0.3 mL).

📏This ensures the client receives the exact prescribed dose without over- or under-dosing.

🧪Octreotide is a potent medication, so precision in dosage calculation is critical to ensure therapeutic effects and avoid adverse reactions.

💉Subcutaneous administration requires accurate volume calculation to prevent tissue irritation or incorrect absorption.

📌Core message

Always divide ordered dose by available concentration to calculate volume to administer.

Answer 3

Correct Answers:

0.8

Rationale :

🧮To calculate mL: 30 mg ÷ (80 mg/2 mL) = 0.75 mL → round to 0.8 mL.

📏This ensures the appropriate anti-inflammatory and analgesic effect of ketorolac is delivered safely.

💉Ketorolac has renal and GI risk, so precise dosing avoids toxicity.

💊Using a concentration-based ratio helps ensure the medication is delivered accurately per provider instructions.

📌Core message

Use proportional math to safely convert medication strength to volume.

Answer 4

Correct Answers:

88

Rationale :

🧮350 mL ÷ 4 hr = 87.5, which rounds to 88 mL/hr.

🩸Infusing at the correct mL/hr rate ensures the client tolerates the blood product over time without circulatory overload.

🧠Packed RBCs require timed and temperature-controlled infusion for safety.

💉Infusing over the prescribed duration prevents hemolysis or fluid-related complications.

📌Core message

Divide total volume by time in hours to get the infusion rate in mL/hr.

Answer 5

Correct Answers:

75

Rationale :

💊Amphotericin B can cause renal toxicity, so a slow, controlled infusion is essential.

🧠Infusing too fast can lead to electrolyte imbalance or anaphylaxis, so rate calculation must be accurate.

📏The large dilution volume helps prevent vein irritation, so the correct hourly rate ensures safe administration.

📌Core message

Calculate infusion rate by dividing fluid volume by infusion time to ensure slow medication delivery.

Answer 6

Correct Answers:

167

Rationale :

🧮1000 mL ÷ 6 hr = 166.66, rounded to 167 mL/hr.

🧪0.9% Sodium chloride is a common isotonic fluid used for hydration or resuscitation.

📏An accurate rate ensures fluid replacement without overloading the circulatory system.

💧Nurses must monitor for signs of fluid overload, especially in cardiac or renal clients.

📌Core message

Always divide total fluid volume by infusion time to get the correct mL/hr rate.

Answer 7

Correct Answers:

44

Rationale :

🧮First, convert 45 minutes to minutes = already in minutes, so proceed to calculate:

(100 mL × 20 gtt/mL) ÷ 45 min = 44.4 → 44 gtt/min.

💧Using the drop factor (gtt/mL) helps calculate the correct manual infusion rate for gravity administration.

🧪Metronidazole requires timed delivery to maintain therapeutic levels and prevent resistance.

📏Setting the correct gtt/min rate also prevents infusion complications such as phlebitis or hypotension.

📌Core message

To calculate gtt/min, multiply volume by drop factor, then divide by minutes of infusion.

Answer 8

Correct Answers:

12

Rationale :

🧮Set up a proportion: (250 mg : 5 mL = 600 mg : X mL) → (600 × 5) ÷ 250 = 12 mL.

💊Amoxicillin dosage accuracy is crucial for bacterial eradication and to prevent resistance.

📏Oral liquid medications require exact volume measurements to ensure full therapeutic effect.

🧠Using proportions for conversions ensures the nurse administers the prescribed dose safely.

📌Core message

Calculate oral liquid doses using a ratio of available strength to ordered amount.

Answer 9

Correct Answers:

111

Rationale :

🧮Use the formula: (250 mL × 20 gtt/mL) ÷ 45 min = 111.1 → 111 gtt/min.

💧Cefazolin, a broad-spectrum antibiotic, must be infused at the prescribed rate to ensure proper blood levels.

🧪An incorrect drip rate could lead to incomplete treatment or adverse effects like phlebitis.

📏Nurses must monitor the rate carefully when using gravity tubing with gtt/mL specifications.

📌Core message

Multiply volume by drop factor, divide by infusion time in minutes to get gtt/min.

Answer 10

Correct Answers:

0.5

Rationale :

🧮Ordered: 5 mg. Available: 10 mg per tablet → 5 ÷ 10 = 0.5 tablet.

💊Glyburide, an oral antidiabetic, must be administered in precise doses to avoid hypoglycemia.

📏Since the tablet is scored, splitting is safe and allows accurate dose delivery.

🧠Over- or under dosing can cause blood glucose instability, so calculation accuracy is critical.

📌Core message

Divide ordered dose by available tablet dose to determine tablet fraction needed.
