Medication Dosage - Ccma

1. What is the household conversion for teaspoons to milliliters?

   $1\,\text{tsp}=5\,\text{mL}$. Standard metric equivalent for household teaspoon measurement in dosing.

2. Identify the correct rounding rule for volumes in a syringe under $1\,\text{mL}$.

   Round to the nearest $0.01\,\text{mL}$. Ensures high precision for small syringe volumes to minimize dosing errors.

3. What is the formula to convert micrograms to milligrams?

   $mg=\frac{mcg}{1000}$. Divides by 1000 because $1\,\text{mg} = 1000\,\text{mcg}$, for unit conversion.

4. What is the formula to convert liters to milliliters?

   $mL=L\times 1000$. Multiplies by 1000 because $1\,\text{L} = 1000\,\text{mL}$, shifting units.

5. What is the formula to convert milligrams to grams?

   $g=\frac{mg}{1000}$. Divides by 1000 since $1\,\text{g} = 1000\,\text{mg}$, converting smaller to larger unit.

6. What is the household conversion for tablespoons to milliliters?

   $1\,\text{tbsp}=15\,\text{mL}$. Accepted conversion for tablespoon in medical and household contexts.

7. What volume is administered if $D=300\,\text{mg}$ and $H=150\,\text{mg}$ per $5\,\text{mL}$?

   $10\,\text{mL}$. Desired is twice the concentration, so doubles the $5\,\text{mL}$ quantity.

8. Convert $125\,\text{mcg}$ to milligrams for documentation.

   $0.125\,\text{mg}$. Divides micrograms by 1000 to express in milligrams accurately.

9. Identify the correct rounding rule for volumes in a syringe at or above $1\,\text{mL}$.

   Round to the nearest $0.1\,\text{mL}$. Provides appropriate accuracy for larger syringe volumes per standard practice.

10. What is the formula to convert grams to milligrams?

    $mg=g\times 1000$. Multiplies by 1000 as $1\,\text{g} = 1000\,\text{mg}$, shifting to smaller unit.

11. How many tablets are given if the order is $750\,\text{mg}$ and tablets are $250\,\text{mg}$ each?

    $3\,\text{tablets}$. Divides total dose by per-tablet strength to get whole number.

12. What is the household conversion for fluid ounces to milliliters?

    $1\,\text{fl oz}=30\,\text{mL}$. Common approximation used in pharmacology for fluid ounce to metric.

13. Convert $0.25\,\text{g}$ to milligrams for documentation.

    $250\,\text{mg}$. Multiplies grams by 1000 for equivalent milligrams in documentation.

14. What volume is drawn up if the order is $0.6\,\text{mg}$ and the vial is $1\,\text{mg}/1\,\text{mL}$?

    $0.6\,\text{mL}$. Directly equals the dose since concentration is $1\,\text{mg/mL}$.

15. What is the formula to convert milligrams to micrograms?

    $mcg=mg\times 1000$. Multiplies by 1000 since $1\,\text{mg} = 1000\,\text{mcg}$, converting to smaller unit.

16. What is the oral liquid formula for milliliters to administer?

    $\text{mL} = \frac{D}{H}\times Q$. Multiplies the ratio of desired to available dose by the volume containing H to calculate the liquid volume required.

17. What is the formula to convert milliliters to liters?

    $L=\frac{mL}{1000}$. Divides by 1000 as $1\,\text{L} = 1000\,\text{mL}$, for volume conversion.

18. Identify the correct documentation entry for an injection dose of $0.75\,\text{mL}$ from a multidose vial.

    Document $0.75\,\text{mL}$ given (dose, route, site, time, initials per policy). Records essential details to comply with legal and safety standards for multidose vials.

19. What is the injectable formula for milliliters to draw up from a vial?

    $\text{mL} = \frac{D}{H}\times Q$. Uses the dosage ratio times the vial's quantity to compute the injectable volume based on concentration.

20. What is the household conversion for cups to milliliters?

    $1\,\text{cup}=240\,\text{mL}$. Standard medical conversion for cup volume in liquid dosing.

21. Identify the correct rounding rule for tablets when the order is not a whole tablet.

    Round to the nearest $\frac{1}{2}$ tablet when scored and allowed. Permits halving scored tablets for practical administration when calculation yields fraction.

22. What is the basic dosage calculation formula using desired, have, and quantity?

    $\text{Dose to give}=\frac{D}{H}\times Q$. This formula scales the available quantity by the ratio of desired dose to available strength to determine the amount to administer.

23. What is the oral tablet formula for number of tablets to administer?

    $\text{Tablets} = \frac{D}{H}$. Divides the desired dose by the strength per tablet to find the number needed, assuming one tablet contains H.

24. What is the maximum number of decimal places recommended when documenting a calculated dose?

    Use no more than $2$ decimal places unless policy specifies otherwise. Prevents unnecessary precision that could lead to documentation errors unless specified.

25. What volume is drawn up if the order is $25\,\text{mg}$ and supply is $50\,\text{mg}/2\,\text{mL}$?

    $1\,\text{mL}$. Half the concentration requires half the $2\,\text{mL}$ volume.
