Sample Questions

1. A patient is prescribed 500 mg of medication. The available tablet is 250 mg. How many tablets should be given?

A. 1
B. 2
C. 3
D. 4

Answer: B. 2

Explanation:
To calculate the number of tablets required, divide the prescribed dose by the dose available per tablet. In this case, 500 mg ÷ 250 mg = 2 tablets. This type of calculation is very common in nursing practice and ensures patients receive the correct dose. Giving too little medication may be ineffective, while too much can be harmful. Accuracy is critical in medication administration, and the exam often tests your ability to perform these calculations quickly and correctly. Always double-check your work to prevent medication errors.

2. Convert 1 gram to milligrams.

A. 10 mg
B. 100 mg
C. 1000 mg
D. 10,000 mg

Answer: C

Explanation:
One gram (g) is equal to 1000 milligrams (mg). This conversion is essential in nursing because medications are often prescribed in different units than they are supplied. Understanding metric conversions helps ensure accurate dosing. For example, if a medication is ordered in grams but supplied in milligrams, you must convert units before calculating the dose. The exam frequently includes conversion questions because they are fundamental to safe medication administration. Remember: 1 g = 1000 mg, and always verify units before calculating.

3. A doctor orders 1 liter of IV fluid over 8 hours. What is the flow rate in mL/hr?

A. 100 mL/hr
B. 125 mL/hr
C. 150 mL/hr
D. 200 mL/hr

Answer: B

Explanation:
First, convert 1 liter to milliliters: 1 L = 1000 mL. Then divide by the time in hours: 1000 mL ÷ 8 hours = 125 mL/hr. This calculation determines the correct IV flow rate to ensure the fluid is delivered evenly over the prescribed time. Accurate IV calculations are essential to avoid underhydration or fluid overload. The exam often tests IV rate calculations because they are a critical nursing skill. Always double-check both the volume and time before calculating.

---

4. A medication order is 0.5 g. How many milligrams is this?

A. 50 mg
B. 500 mg
C. 1000 mg
D. 1500 mg

Answer: B

Explanation:
To convert grams to milligrams, multiply by 1000. Therefore, 0.5 g × 1000 = 500 mg. This conversion is commonly required in nursing calculations because medications may be prescribed in grams but administered in milligrams. Understanding these conversions helps prevent dosing errors and ensures patient safety. The exam frequently includes unit conversion questions, making it important to practice them regularly.

---

5. A patient needs 250 mg of medication. The available solution is 125 mg per 5 mL. How many mL should be given?

A. 5 mL
B. 10 mL
C. 15 mL
D. 20 mL

Answer: B

Explanation:
Set up a proportion: 125 mg = 5 mL, so 250 mg = x mL. Since 250 mg is double 125 mg, the volume is double 5 mL, which equals 10 mL. This method ensures accurate medication administration. Dosage calculations like this are common in nursing practice and require careful attention to detail. Always verify your calculations before administering medication to ensure patient safety.

---

6. Convert 500 mL to liters.

A. 0.5 L
B. 5 L
C. 50 L
D. 0.05 L

Answer: A

Explanation:
To convert milliliters to liters, divide by 1000. Therefore, 500 mL ÷ 1000 = 0.5 L. This conversion is essential when working with IV fluids and medication orders. The exam often tests your ability to switch between units quickly and accurately.

---

7. A patient is to receive 60 drops per minute. How many drops per second is this?

A. 1
B. 2
C. 3
D. 4

Answer: A

Explanation:
There are 60 seconds in a minute, so 60 drops per minute equals 1 drop per second. This type of calculation is important for manual IV administration. Understanding time-based conversions ensures accurate flow rates and patient safety.

---

8. A medication is ordered as 2 tablets every 6 hours. How many tablets in 24 hours?

A. 4
B. 6
C. 8
D. 10

Answer: C

Explanation:
There are 24 hours in a day, and doses are given every 6 hours. So, 24 ÷ 6 = 4 doses per day. Each dose is 2 tablets, so 4 × 2 = 8 tablets. This calculation ensures proper scheduling and dosing frequency. The exam often includes timing and frequency questions to test your understanding of medication schedules.

---

9. A patient weighs 70 kg. If the dose is 2 mg/kg, what is the total dose?

A. 120 mg
B. 140 mg
C. 160 mg
D. 180 mg

Answer: B

Explanation:
Multiply the patient’s weight by the dose per kilogram: 70 kg × 2 mg/kg = 140 mg. Weight-based dosing is common in nursing, especially for medications like antibiotics. Accurate calculations are essential to ensure safe and effective treatment. The exam frequently tests this concept.

---

10. What is the most important rule in medication calculations?

A. Speed
B. Accuracy
C. Guessing
D. Estimation

Answer: B

Explanation:
Accuracy is the most important rule in medication calculations. Even small errors can lead to serious consequences for patients. Nurses must carefully check calculations, verify units, and ensure correct dosing before administration. While speed is helpful, it should never compromise accuracy. The exam emphasizes safe practices because patient safety is the top priority in healthcare. Developing strong calculation skills and double-checking your work are essential habits for every nurse.
