Question

A client is receiving a secondary infusion of vancomycin 1,500 mg in 250 ml to be infused over two hours. The intravenous (IV) administration set delivers 15 gtt/ml. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If sounding is required, round to the nearest whole number.)

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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

Answer 7

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.

Answer 8

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

Answer 9

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

Answer 10

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
