#1
What is the formula for calculating intravenous medication flow rate?
Volume (in mL) × Time (in min) ÷ Drop factor
ExplanationFlow rate is calculated by multiplying volume, time, and drop factor.
#2
What is the primary purpose of calculating IV medication flow rate?
To ensure the patient receives the correct dosage
ExplanationCalculating flow rate ensures accurate dosage administration.
#3
What is the drop factor for a microdrip IV set?
15 drops/mL
ExplanationA microdrip IV set typically has a drop factor of 15 drops/mL.
#4
What is the primary role of a healthcare professional in verifying IV medication dosages?
To double-check calculations for accuracy
ExplanationHealthcare professionals verify IV medication dosages by double-checking calculations for accuracy.
#5
A medication is available in a concentration of 25 mg/mL. How many milligrams of the medication are in 10 mL of the solution?
250 mg
ExplanationCalculation: Concentration × Volume = 25 mg/mL × 10 mL = 250 mg.
#6
Which of the following factors does not affect IV medication dosage calculation?
Patient's age
ExplanationPatient's age does not impact IV medication dosage calculation.
#7
A patient needs to receive 500 mL of IV medication over 4 hours using an infusion set with a drop factor of 15 drops/mL. What is the flow rate in drops per minute?
31.25 drops/min
ExplanationFlow rate calculation: (Volume ÷ Time) × Drop factor = 31.25 drops/min.
#8
What is the purpose of using a burette in intravenous medication administration?
To regulate the flow rate of medication
ExplanationA burette is used to control and regulate the flow rate of medication.
#9
A patient is prescribed 1500 mL of IV fluid to be administered over 8 hours using a macrodrip set with a drop factor of 20 drops/mL. What is the flow rate in drops per minute?
62.5 drops/min
ExplanationFlow rate calculation: (Volume ÷ Time) × Drop factor = 62.5 drops/min.
#10
What is the maximum volume of medication that can typically be administered via an intravenous bolus injection?
50 mL
ExplanationThe maximum volume for an intravenous bolus injection is typically 50 mL.
#11
Which equation is used to calculate the total volume of IV medication to be administered?
Volume (in mL) = Flow rate (in mL/hr) × Time (in hours)
ExplanationTotal volume is calculated using the formula: Volume = Flow rate × Time.
#12
Which of the following factors can cause variations in IV medication absorption rates in patients?
Tissue integrity at the injection site
ExplanationTissue integrity at the injection site can affect medication absorption rates.
