Explanation:

First Question (Sertraline Tablets)

Step1: Identify dose and available strength

Ordered dose: 50 mg, Available tablet strength: 100 mg/tablet.

Step2: Calculate tablets per dose

Use formula: Tablets = $\frac{\text{Ordered Dose}}{\text{Available Strength}}$ = $\frac{50\ \text{mg}}{100\ \text{mg/tablet}}$ = 0.5 tablet.

Step1: Identify dose and concentration

Ordered dose: 100 mg, Medication concentration: 80 mg/mL.

Step2: Calculate volume

Use formula: Volume (mL) = $\frac{\text{Ordered Dose}}{\text{Concentration}}$ = $\frac{100\ \text{mg}}{80\ \text{mg/mL}}$ = 1.25 mL.

Answer:

0.5 tablet (Option: 0.5 tablet)
