1.      The patient is to take 12.5 mg of a drug twice a day. The medication is supplied in 15 mg / 10 ml. How many teaspoons will you administer for a single dose?  ______________ 

To find how many teaspoons to administer for a single dose, we first need to convert the dosage and then the units.

### Step-by-Step Solution:
1. **Determine the dose needed**:  
   The patient is to take **12.5 mg** of the drug twice a day.

2. **Concentration of medication**:  
   The medication is supplied as **15 mg / 10 mL**.

3. **Set up a proportion to calculate the required volume in mL**:
   \[
   \frac{15 \, \text{mg}}{10 \, \text{mL}} = \frac{12.5 \, \text{mg}}{x \, \text{mL}}
   \]
   Solving for \( x \):
   \[
   x = \frac{12.5 \, \text{mg} \times 10 \, \text{mL}}{15 \, \text{mg}} = \frac{125}{15} \approx 8.33 \, \text{mL}
   \]

4. **Convert mL to teaspoons**:
   There are **5 mL** in 1 teaspoon, so:
   \[
   \frac{8.33 \, \text{mL}}{5 \, \text{mL/teaspoon}} \approx 1.67 \, \text{teaspoons}
   \]

### Final Answer:
You would administer **1.67 teaspoons** for a single dose.
