Question

A client with dehydration is prescribed a potassium chloride infusion at 10 mEq/hr. Potassium chloride 80 mEq is mixed with 1 liter of normal saline. The nurse should regulate the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number.)

Answer 1

Correct Answers:

125

Rationale :

⏺️ The IV bag contains 80 mEq of potassium chloride in 1,000 mL of normal saline.

⏺️ The prescription is to infuse 10 mEq per hour.

⏺️ Step-by-step Calculation:

Determine the potassium concentration:
80 mEq/1000 mL=0.08 mEq/mL
Calculate how many mL will deliver 10 mEq:
10 mEq/0.08 mEq/mL=125 mL/hr

Answer 2

Correct Answers:

0.9

Rationale :

✔Ordered dose: 90 mg ✔Available concentration: 100 mg per 1 mL

✔Use the formula: 👉Volume (mL)= Desired dose (mg)/Available concentration (mg/mL)

✔Volume=90/100 =0.9 mL

Answer 3

Correct Answers:

0.8

Rationale :

⏺️ Prescribed dose: 300 mg

⏺️ Available concentration: 1 gram (1,000 mg) in 2.5 mL

⏺️ Step-by-step calculation:

Convert 1 gram to milligrams:
1,000 mg=2.5 mL
Use the formula: 🔷Volume (mL)=Desired dose/Available concentration ✍=300/1000×2.5=0.75 mL
Rounded to the nearest tenth: 0.8 mL

Answer 4

Correct Answers:

375

Rationale :

⏺️ Total volume ordered: 1000 mL

⏺️ Infusion rate: 125 mL/hour

⏺️ Time elapsed: 5 hours

⏺️ Step-by-step Calculation:

Volume infused so far: 125 mL/hr×5 hours=625 mL
Volume remaining:1000 mL−625 mL=375 mL

Answer 5

Correct Answers:

97.7

Rationale :

To convert Celsius to Fahrenheit, ✍Use the formula:

°F=(°C×9/5)+32

°F=(36.5×1.8)+32=65.7+32=97.7

Answer 6

Correct Answers:

120

Rationale :

Prescribed rate: 2 mg/min
Available drug: 200 mg labetalol in 200 mL of solution

⏺️ Step 1: Calculate drug concentration

Concentration=200 mg/200 mL=1 mg/mL

⏺️ Step 2: Determine volume needed for 2 mg

2 mg/min=2 mL/min because 1 mg = 1 mL

⏺️ Step 3: Convert mL/min to mL/hour

2 mL/min×60 min/hour=120 mL/hour

Answer 7

Correct Answers:

1.0

Rationale :

✍️ Prescribed dose: 5 mcg/kg

✍️ Client weight: 59 kg

✍️ Available concentration: 300 mcg/mL

✍️ Step 1: Calculate total dose 5 mcg×59 kg=295 mcg

✍️ Step 2: Calculate mL to administer 295 mcg/300 mcg/mL=0.983 mL

✍️ Step 3: Round to the nearest tenth= 1.0 mL

Answer 8

Correct Answers:

83

Rationale :

✍️ Total volume prescribed: 1 liter = 1000 mL

✍️ Time to infuse: 12 hours

✍️ Use the formula: Rate (mL/hr)=Total volume (mL)/Time (hr)

Rate=1000/12=83.33 =83 mL/hr

Answer 9

Correct Answers:

0.7

Rationale :

✍️ Prescribed dose: 35 mg

✍️ Available concentration: 50 mg/mL

✍️ Use the formula: mL=Desired dose (mg)/Available concentration (mg/mL) =35/50=0.7 mL

Answer 10

Correct Answers:

56

Rationale :

✍️ Total volume: 2 liters = 2000 mL

✍️ Time: 12 hours = 720 minutes

✍️ Drop factor: 20 gtt/mL

✍️ Use the formula: 📌Flow rate (gtt/min)=Volume (mL)×Drop factor (gtt/mL)/Time (min)

➡2000×20/720=40000/720 =56 gtt/min
