Conversion Table For Nurses

Nurses play a crucial role in administering medications to patients. To ensure the safe and effective delivery of these medications, nurses must possess a thorough understanding of medication calculations. When administering medications, nurses need to convert medication doses from one unit of measure to another. This article provides a comprehensive conversion table that nurses can use as a quick reference guide for commonly used medications.

Importance of Conversion Calculations:

Conversions are essential for accurately calculating the correct medication dose for each patient. The wrong dosage can result in adverse drug effects, such as toxicity or ineffectiveness. By knowing how to convert dosages accurately, nurses can help prevent medication errors and ensure patient safety.

Numeric Conversion Techniques:

1. Decimal to Fraction: Move the decimal point to the right by the number of zeros in the denominator of the fraction. For example, to convert 0.5 to a fraction, move the decimal point two places to the right, which gives you 5/10 and simplifies to 1/2.

2. Fraction to Decimal: Divide the numerator by the denominator. For example, to convert 1/2 to a decimal, divide 1 by 2, which gives you 0.5.

3. Converting Different Units of Measure: Multiply by the conversion factor. For example, to convert 1 gram to milligrams, multiply by 1000 (1 g = 1000 mg).

Medication Dosages:

1. Oral Medications: Milliliters (mL) to milligrams (mg) and milligrams (mg) to milliliters (mL)
2. Parenteral Medications: Milliliters (mL) to micrograms (mcg) and micrograms (mcg) to milliliters (mL)
3. Infusions: Micrograms per minute (mcg/min) to milliliters per hour (mL/hr) and milliliters per hour (mL/hr) to micrograms per minute (mcg/min)

Example:

Calculate the number of milligrams in 5 mL of a 2 mg/mL oral medication.

• 5 mL (volume) x 2 mg/mL (concentration) = 10 mg (dose)

Common Conversions:

mL <-> mg: Divide mL by the concentration (mg/mL) to convert to mg; multiply mg by the concentration to convert to mL
mL <-> mcg: Divide mL by the concentration (mcg/mL) to convert to mcg; multiply mcg by the concentration to convert to mL
mcg/min <-> mL/hr: Divide mcg/min by 60 to convert to mL/hr; multiply mL/hr by 60 to convert to mcg/min

Utilizing a Conversion Table:

Nurses can use the conversion table provided in this article to quickly and accurately convert doses for medications commonly encountered in clinical practice. The table includes the most frequently used conversions, allowing nurses to easily compare different units of measure.

Conclusion:

Medication calculations are fundamental to safe nursing practice. By using a conversion table and understanding the principles of numeric conversion, nurses can confidently and accurately measure and administer medications, ensuring optimal patient care. This article provides a valuable resource for nurses to enhance their understanding of medication conversions and contribute to patient safety.
