A patient receives a 6 oz bottle of medication. The physician prescribes 5 mL q.i.d. How many doses does the bottle contain?
The bottle contains 36 doses of medication.
To determine the number of doses in a 6 oz bottle when each dose is 5 mL and prescribed four times a day (q.i.d.), we first convert ounces to milliliters and then calculate the total doses available.
This choice represents a misunderstanding of the total volume available in the bottle. If only 5 doses were available, it would imply that the total volume of the medication is only 25 mL (5 doses x 5 mL), which is far less than the 6 oz provided.
Choosing 9 doses suggests that the total volume of the medication is 45 mL (9 doses x 5 mL). This is still insufficient compared to the 6 oz bottle, which contains 177.44 mL, indicating a significant underestimation of the available doses.
This option indicates that the total volume of the medication is 90 mL (18 doses x 5 mL), which also falls short of the total volume available in the 6 oz bottle. It does not account for the full capacity of the medication provided.
This is the correct answer as it accurately reflects the total number of doses from the bottle. Converting 6 oz to milliliters gives approximately 177.44 mL. Dividing this by 5 mL per dose results in 35.49 doses, rounded to 36 doses, confirming the total available in the bottle.
In summary, the calculation of doses from a 6 oz bottle of medication prescribed at 5 mL q.i.d. results in a total of 36 doses. Understanding unit conversions and dosage calculations is critical for accurate medication administration, ensuring patients receive the correct amount of medication over the prescribed period.
