The healthcare provider prescribes interferon beta-1b 0.0625 mg subcutaneously every other day for a client with multiple sclerosis. The nurse reconstitutes the single-use vial of powder labeled 0.3 mg with 1.2 mL of sterile water. How many mL should the nurse administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest hundredth.)
-
0.25
Explanation
The concentration after reconstitution is 0.3 mg ÷ 1.2 mL = 0.25 mg/mL. Using the formula dose ordered ÷ dose on hand: 0.0625 mg ÷ 0.25 mg/mL = 0.25 mL.
Correct Answer Is:
0.25
The healthcare provider prescribes a hydration infusion of normal saline to run over 3 hours at 30 mL/kg for a client who is dehydrated and weighs 70 kg. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
-
700
Explanation
The total volume is calculated by multiplying the client's weight by the prescribed dose: 70 kg × 30 mL/kg = 2,100 mL. This total volume must infuse over 3 hours: 2,100 mL ÷ 3 hours = 700 mL/hour.
Correct Answer Is:
700
A 4-year-old is admitted with croup and receives a prescription for a single dose of dexamethasone 0.6 mg/kg IM. The child weighs 35 pounds. How many mg should the nurse administer
-
8 mg
-
10 mg
-
9 mg
-
11 mg
Explanation
Correct Answer B: 10 mg
Explanation:
Step 1: Convert weight to kilograms
35 lb ÷ 2.2 = 15.91 kg
Step 2: Multiply by prescribed dose
0.6 mg/kg × 15.91 kg = 9.55 mg
Step 3: Round to the nearest whole number
9.55 mg rounds to 10 mg
Why the Other Options Are Incorrect:
A. 8 mg
Would underdose the child and not meet the required therapeutic level.
C. 10 mg
This is the correct dose based on rounding and is not incorrect.
D. 11 mg
Would exceed the recommended dose based on weight.
Prior to performing an electroencephalogram, the healthcare provider prescribes a sedative dose of 35 mg/kg PO to an infant who weighs 11 pounds. The medication is labeled 500 mg/5 mL. How many mL should the nurse administer to this infant? (Enter numerical value only. If rounding required, round to the nearest tenth.)
-
1.8
Explanation
First convert the infant's weight to kilograms: 11 lb ÷ 2.2 = 5 kg. The dose is calculated as 5 kg × 35 mg/kg = 175 mg. Finally, calculate the volume: 175 mg ÷ 500 mg × 5 mL = 1.75 mL, which rounds to 1.8 mL.
Correct Answer Is:
1.8
A child weighing 67 pounds receives a prescription for benztropine 0.61 mg IV every 12 hours. This drug is available as 1 mg/mL ampules. How many mL should the nurse administer? (Enter the numeric value only. If rounding is required, round to the nearest hundredth.)
-
0.61
Explanation
The child's weight is not needed since the dose is already prescribed in mg rather than mg/kg. Using the formula dose ordered ÷ dose on hand: 0.61 mg ÷ 1 mg/mL = 0.61 mL.
Correct Answer Is:
0.61
The healthcare provider prescribes an IV solution of regular insulin 100 units in 250 mL of 0.45% saline to infuse at 12 units/hour. The nurse should program the infusion pump to deliver how many mL/hour
-
25 mL/hr
-
30 mL/hr
-
35 mL/hr
-
40 mL/hr
Explanation
Correct Answer B: 30 mL/hr
Explanation:
Step 1: Determine the concentration of insulin in the solution
100 units ÷ 250 mL = 0.4 units/mL
Step 2: Calculate the volume needed for 12 units/hour
12 units ÷ 0.4 units/mL = 30 mL/hour
Why the Other Options Are Incorrect:
A. 25 mL/hr
Delivers only 10 units/hour—underdosing the client.
C. 35 mL/hr
Delivers 14 units/hour—more than prescribed.
D. 40 mL/hr
Delivers 16 units/hour—significantly exceeds the ordered rate.
The healthcare provider prescribes heparin 1,000 units subcutaneously twice a day. The available vial is labeled, "Heparin Sodium Injection 2,000 units/2 mL." How many mL should the nurse administer
-
0.5 mL
-
1 mL
-
1.5 mL
-
2 mL
Explanation
Correct Answer B: 1 mL
Explanation:
The vial contains 2,000 units in 2 mL, which means:
2,000 units ÷ 2 mL = 1,000 units per mL
The prescribed dose is 1,000 units, so:
1,000 units ÷ 1,000 units/mL = 1 mL
Why the Other Options Are Incorrect:
A. 0.5 mL
This would deliver only 500 units, which is half the prescribed dose.
C. 1.5 mL
This would provide 1,500 units, exceeding the ordered amount.
D. 2 mL
This would deliver 2,000 units—double the correct dose and potentially harmful.
A client who is scheduled for induction of labor receives a prescription for oxytocin 2 milliunits/min intravenously (IV). The IV bag contains oxytocin 20 units in lactated Ringer's 1 liter. How many mL/hour should the nurse program the infusion pump to deliver? (Enter numeric value only.)
-
6
Explanation
Convert the bag concentration to milliunits: 20 units × 1,000 = 20,000 milliunits in 1,000 mL, which equals 20 milliunits/mL. To deliver 2 milliunits/min, divide the desired dose by the concentration: 2 milliunits/min ÷ 20 milliunits/mL = 0.1 mL/min. Converting to an hourly rate: 0.1 mL/min × 60 min/hour = 6 mL/hour.
Correct Answer Is:
6
The healthcare provider (HCP) prescribes erythromycin suspension 250 mg PO every 6 hours for a child with streptococcal pharyngitis. The drug is available in a suspension labeled, "200 mg/5 mL." How many mL should the nurse administer
-
5.75 mL
-
6.00 mL
-
6.25 mL
-
6.50 mL
Explanation
Correct Answer C: 6.25 mL
Explanation:
Step 1: Use the formula:
(Dose ordered × Volume) ÷ Dose on hand = mL to administer
(250 mg × 5 mL) ÷ 200 mg =
1,250 ÷ 200 = 6.25 mL
Why the Other Options Are Incorrect:
A. 5.75 mL
Delivers 230 mg—less than prescribed.
B. 6.00 mL
Delivers 240 mg—still under the required 250 mg dose.
D. 6.50 mL
Delivers 260 mg—more than ordered, risking overtreatment.
The nurse is reviewing instructions with a client who is to take 120 mL of a carbohydrate-balanced meal replacement four times a day, three hours postprandial. The client has a measuring cup marked in ounces. How many ounces should the client take for each dose
-
3.5 oz
-
4.0 oz
-
4.1 oz
-
4.5 oz
Explanation
Correct Answer C: 4.1 oz
Explanation:
Step 1: Use the conversion factor
1 ounce = 29.5735 mL
Step 2: Convert 120 mL to ounces
120 mL ÷ 29.5735 = 4.06 oz, rounded to the nearest tenth = 4.1 oz
Why the Other Options Are Incorrect:
A. 3.5 oz
Equals only about 103.5 mL—less than the prescribed 120 mL.
B. 4.0 oz
Equals about 118.3 mL—slightly under the prescribed dose.
D. 4.5 oz
Equals about 133 mL—exceeds the prescribed volume.
