Hint : 💎Volume × drop factor ÷ time (min) = gtt/min.

Correct Answers:

  • 31


Rationale :

💎 Volume to infuse: 250 mL

💎 Time: 2 hours = 120 minutes

💎 Drop factor: 15 gtt/mL

💎 Step-by-step calculation: gtt/min=Volume (mL)×Drop factor (gtt/mL)/Time (min)

=250×15/120​=3750​/120 =31 gtt/min​

Hint : 💎Rate × time = total volume, then multiply by units per mL.

Correct Answers:

  • 12000


Rationale :

💎 Total heparin in bag: 20,000 units

💎 Total volume: 500 mL

💎 Infusion rate: 25 mL/hour

💎 Duration: 12 hours

💎 Step 1: Calculate units per mL

20,000 units/500 mL=40 units/mL

💎 Step 2: Calculate total volume in 12 hours

25 mL/hr×12 hours=300 mL

💎 Step 3: Calculate total units received

300 mL×40 units/mL=12,000 units

Hint : 🧪Use ratio to convert mg to mL.

Correct Answers:

  • 0.42


Rationale :

✏️ Prescription Details:

Ordered dose: 0.0625 mg

Available concentration: 0.3 mg reconstituted with 2 mL sterile water

✏️ Step 1: Set up a proportion using the available concentration to determine how many mL contain 0.0625 mg:

0.0625 mg/0.3 mg=x/2 mL

✏️ Step 2: Cross-multiply and solve for x (the volume in mL): 0.0625×2=0.125

0.125​/3=0.4167 mL

✏️Step 3: Round to the nearest hundredth as instructed: 0.42 mL

Hint : 💧Volume ÷ hours = rate.

Correct Answers:

  • 111


Rationale :

✏️ Total volume to infuse: 1 liter = 1000 mL

✏️ Total time: 9 hours

✏️ Use the formula Rate (mL/hr) Total volume (mL)/Time (hr)=1000/9=111.1

✏️ Rounded to the nearest whole number: 111 mL/hr

Hint : 💉 Draw up 2.4 mL from reconstituted vial.

Correct Answers:

  • 2.4


Rationale :

✏️To determine how many mL to administer for a prescribed dose of 800 mg when using a reconstituted vial of 1 gram (1000 mg) in 3.0 mL,

Follow this step-by-step calculation:

✏️ Available concentration:

1 gram = 1000 mg in 3.0 mL

So, concentration =1000 mg/3.0 mL=333.33 mg/mL

✏️ Desired dose: 800 mg

✏️ Volume to administer:800 mg/333.33 mg/mL=2.4 mL

Hint : 💧Use formula: (Volume × Drop Factor) ÷ Time

Correct Answers:

  • 42


Rationale :

✏️ Total volume = 500 mL

✏️ Total time = 2 hours = 120 minutes

✏️ Drop factor = 10 gtt/mL

✏️Use the formula:

gtt/min=Volume (mL)×Drop factor (gtt/mL)/Time (min) gtt/min=500×10/120=5000/120=41.67

✏️ Rounded to the nearest whole number = 42 gtt/min

Hint : ⚖️Convert pounds to kg, then multiply by dose per kg.

Correct Answers:

  • 2000


Rationale :

✏️ Child's weight = 88 pounds

✏️ Convert to kilograms: 88÷2.2=40 kg

✏️ Dosage ordered = 50 mg/kg/day

50×40=2000 mg/day

✏️ This represents the total daily dose of ampicillin the child should receive.

Hint : 💧Use formula: (mL × drop factor) ÷ time in minutes.

Correct Answers:

  • 21


Rationale :

✏️ Total volume 2 liters = 2000 mL

✏️ Time 24 hours = 1440 minutes

✏️ Drop factor 15 gtt/mL

✏️Use the formula: gtt/min=Volume×Drop Factor/Time in minutes 2000×15/1440=30000/1440=20.83

✏️ Rounded to the nearest whole number = 21 gtt/min

Hint : 💉Dose desired ÷ dose on hand × mL = mL to give.

Correct Answers:

  • 2.4


Rationale :

✏️ Prescribed dose:

0.6 mg = 600 mcg

✏️ Available vial:

500 mcg in 2 mL

✏️Set up a proportion to solve for the volume (x):

500 mcg/2 mL=600 mcg/x

✏️Cross-multiply: 500x=1200⇒x=1200/500=2.4 mL

Hint : 💉Volume ÷ Time = Pump Rate.

Correct Answers:

  • 100


Rationale :

✏️ Total volume = 150 mL

✏️ Total time = 90 minutes = 1.5 hours

✏️Use the formula:

mL/hour=Total volume/Time in hours=150/1.5=100
