Question

a physician orders 2 teaspoons daily of a certain drug in five equally divided doses. refer to the appropriate entries in the table of english and metric equivalents for capacity to convert given units to the unit indicated. complete parts a. through d.
click to check the table of english and metric equivalents for capacity.
a. how many milliliters of the drug should be administered daily?
(round to two decimal places as needed.)
b. how many cc of the drug should be administered daily?
(round to two decimal places as needed.)
c. how many fluid ounces of the drug should be administered daily?
(round to two decimal places as needed.)
d. how many fluid ounces of the drug should the patient receive in each divided dose?
(round to two decimal places as needed.)

Explanation:

Step1: Convert teaspoons to milliliters

Since \(1\) teaspoon (\(tsp\))\(\approx5\) milliliters (\(mL\)), for \(2\) teaspoons, we use the formula \(V = 2\times5\).

$$V=2\times5 = 10\space mL$$

Step2: Convert milliliters to \(cc\)

Given \(1\space cc = 1\space cm^{3}=1\space mL\), so if \(V = 10\space mL\), then \(V = 10\space cc\)

Step3: Convert milliliters to fluid ounces

Since \(1\) fluid ounce (\(fl\space oz\))\(\approx30\) milliliters (\(mL\)), let \(x\) be the number of fluid ounces. We use the proportion \(\frac{x}{1}=\frac{10}{30}\)

$$x=\frac{10}{30}\approx0.33\space fl\space oz$$

Step4: Divide the daily fluid - ounce dose into five equal parts

Let \(y\) be the dose per part. We know the daily fluid - ounce dose is approximately \(0.33\space fl\space oz\). Using the formula \(y=\frac{0.33}{5}\)

$$y = 0.07\space fl\space oz$$

Answer:

a. \(10.00\)
b. \(10.00\)
c. \(0.33\)
d. \(0.07\)
