Question 1 of 5
A nurse is preparing to administer valproic acid 500 mg PO. Available is valproic acid oral solution 250 mg/5 mL. How many mL should the nurse administer?
Correct Answer: A
Rationale:
To deliver 500 mg: (500 mg / 250 mg) × 5 mL = 10 mL.
Question 2 of 5
A nurse is reinforcing teaching to a school-age child who has asthma. Which of the following medications should the nurse instruct the child to use to abort an ongoing attack?
Correct Answer: D
Rationale: Albuterol, a short-acting beta agonist, rapidly relieves acute asthma symptoms by relaxing airway muscles. Montelukast, fluticasone, and cromolyn are maintenance medications, not suitable for aborting an ongoing attack.
Question 3 of 5
A nurse is preparing to administer 1,000 mL of lactated Ringer's IV over 6 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?
Correct Answer: A
Rationale: Using the formula (volume × drop factor) / time in minutes: (1000 mL × 10 gtt/mL) / 360 min = 27.78 gtt/min, rounded to 28 gtt/min.
Question 4 of 5
A nurse is reinforcing teaching to a school-age child who has asthma. Which of the following medications should the nurse instruct the child to use to abort an ongoing attack?
Correct Answer: D
Rationale: Albuterol is used to rapidly relieve acute asthma symptoms, unlike montelukast, fluticasone, or cromolyn, which are for long-term control.
Question 5 of 5
The healthcare provider has ordered 1000 mL of 0.9% sodium chloride to be administered intravenously over 5 hours. The drop factor on the tubing is 15 drops/mL. How many milliliters per hour will you administer and how many drops per minute?
Correct Answer: C
Rationale: Rate: 1000 mL / 5 hr = 200 mL/hr. Drops/min: (1000 mL × 15 drops/mL) / (5 × 60 min) = 50 drops/min.
