When you don’t seem to get any better, you eventually end up in the hospital.  The doctor orders a dosage amount of 120 mg of medicine.  The nurse comes in with 6 tablets and tells you that there are 30 mg in each tablet.  Is this the correct dosage?  If not, how many tablets should you get? Using quantitative literacy

To solve this problem using quantitative literacy, we'll break it down step by step, focusing on understanding the quantities and their relationships.

### Step 1: Understand the Given Information
- The **doctor's order** is for a **total dosage of 120 mg**.
- The **nurse provides 6 tablets**.
- Each tablet contains **30 mg** of the medicine.

### Step 2: Calculate the Total Dosage Provided
The total dosage provided by the nurse can be calculated by multiplying the number of tablets by the amount of medicine in each tablet:

\[
\text{Total dosage provided} = \text{Number of tablets} \times \text{Dosage per tablet}
\]

Substituting the given values:

\[
\text{Total dosage provided} = 6 \times 30 \text{ mg} = 180 \text{ mg}
\]

### Step 3: Compare the Total Dosage Provided to the Doctor's Order
- The doctor ordered **120 mg**.
- The nurse provided **180 mg**.

Since **180 mg** is greater than the prescribed **120 mg**, the dosage provided by the nurse is **incorrect**.

### Step 4: Determine the Correct Number of Tablets
To find the correct number of tablets to achieve the prescribed dosage:

\[
\text{Number of tablets required} = \frac{\text{Prescribed dosage}}{\text{Dosage per tablet}}
\]

Substituting the given values:

\[
\text{Number of tablets required} = \frac{120 \text{ mg}}{30 \text{ mg/tablet}} = 4 \text{ tablets}
\]

### Conclusion
The correct dosage is **4 tablets**. The nurse should have provided 4 tablets, not 6.
