Sample Questions and Answers

uestion 1. A healthcare provider prescribes 500 mg of a medication. The available tablets contain 250 mg each. How many tablets should the nurse administer?

A. 1 tablet

B. 2 tablets

C. 3 tablets

D. 4 tablets

Correct Answer: B

Explanation:
To determine the correct number of tablets, divide the prescribed dose by the amount of medication contained in each tablet. In this case, 500 mg divided by 250 mg equals 2 tablets. Accurate dosage calculations are essential for safe medication administration because even small errors can result in underdosing or overdosing. Nurses should always verify the prescribed dose, the medication strength, and the calculation before administering any medication. Developing strong calculation skills through regular practice helps improve patient safety and confidence during medication administration.

Question 2. A patient weighs 70 kg, and the prescribed medication dose is 5 mg/kg. What is the total dose the patient should receive?

A. 300 mg

B. 325 mg

C. 350 mg

D. 375 mg

Correct Answer: C

Explanation:
Weight-based medication calculations are commonly used to ensure patients receive doses appropriate for their body weight. Multiply the patient’s weight by the prescribed dose per kilogram. For this question, 70 kg × 5 mg/kg equals 350 mg. Before administering the medication, nurses should confirm the patient’s current weight, verify the prescribed dose, and compare the result with recommended dosing guidelines when applicable. Accurate weight-based calculations are particularly important because incorrect calculations can significantly affect medication safety and treatment effectiveness.

Question 3. An IV infusion contains 1,000 mL of normal saline and is prescribed to infuse over 8 hours. What is the infusion rate in mL/hour?

A. 100 mL/hour

B. 120 mL/hour

C. 125 mL/hour

D. 150 mL/hour

Correct Answer: C

Explanation:
To calculate the infusion rate, divide the total volume by the total infusion time. In this example, 1,000 mL divided by 8 hours equals 125 mL/hour. Correct IV flow rate calculations help ensure patients receive fluids and medications at the prescribed rate while reducing the risk of complications caused by infusing too quickly or too slowly. Nurses should always verify infusion settings before starting therapy and continue monitoring the patient and equipment throughout the infusion to ensure safe and accurate fluid administration.

Question 4. A medication order requires 750 mL of IV fluid to be infused over 5 hours. What should the infusion pump be set to?

A. 125 mL/hour

B. 150 mL/hour

C. 175 mL/hour

D. 200 mL/hour

Correct Answer: B

Explanation:
The infusion rate is calculated by dividing the total volume by the infusion time. Dividing 750 mL by 5 hours gives an infusion rate of 150 mL/hour. Programming the infusion pump correctly is essential to ensure the patient receives the prescribed amount of fluid within the correct timeframe. Incorrect pump settings can delay treatment or increase the risk of fluid overload and medication errors. Nurses should independently verify calculations and confirm pump settings before beginning the infusion to promote patient safety.

Question 5. A liquid medication is prescribed as 15 mL. The medicine cup is marked in 5 mL increments. Which amount should the nurse administer?

A. 5 mL

B. 10 mL

C. 15 mL

D. 20 mL

Correct Answer: C

Explanation:
The prescribed dose is 15 mL, so the nurse should accurately measure and administer exactly 15 mL using an appropriate measuring device. Reading the medication cup at eye level and using the correct measuring equipment helps improve dosing accuracy. Even simple liquid medication calculations require careful attention because incorrect measurements may affect the medication’s effectiveness or increase the risk of adverse effects. Accurate medication measurement is a fundamental nursing skill and is frequently assessed in nursing math exams and medication calculation competency tests.
