Question

Working in the health sciences, you will find that you will have to make different kinds of mathematical conversions. Start this activity by reading through the following story problems to familiarize yourself with the various conversions that you will need to perform. Use the information below to answer the questions.Submit your answer (rounded to 2 decimals) and all work.Conversion Formulas1 oz = 29.57mL1 ml = 0.20 teaspoonsQuestion 4: A patient is prescribed 6 mg of cough medication. The label on the prescription says there are 2 mg per 4 mL. How many teaspoons of cough medication does the patient need to take?Question 5: A patient requires 80 milligrams of Risperidone. The stock dose is 40mg / 10mL. What volume is required?

Answer 1

Question 4

Step1: Write out the given information

`\begin{gathered} \text{Quantity prescribe: 6mg} \\ \text{label on the prescription =2mg per 4ml} \end{gathered}`

Step2: Convert the quantity prescribe to ml

`\begin{gathered} 2mg\text{ contains 4ml} \\ 6mg\text{ will contains }(6*4)/(2)=(24)/(2)=12ml \end{gathered}`

Step3: Convert 12ml to the number of teaspoons using the conversion formula

`1ml=0.20\text{ teaspoon}`

Hence

`\begin{gathered} \text{if 1ml=0.2teaspoon} \\ \text{then } \\ 12ml\text{ = 12}*0.2=12*(2)/(10)=(24)/(10)=2.4\text{ teaspoon } \end{gathered}`

Therefore the number of teaspoons of cough medicine the patient needs to take is 2.4
