Explanation:

Step1: Calculate the dosage of Ondansetron

We know the ordered dose is 3 mg and the available concentration is 4 mg/2 mL. Use the proportion formula $V=\frac{D}{C}\times V_0$, where $D$ is the desired dose, $C$ is the concentration, and $V_0$ is the volume - related to the concentration. Here, $C = 4$ mg/2 mL, $D = 3$ mg. First, find the concentration per mL: $C = 2$ mg/mL. Then $V=\frac{3}{2}=1.5$ mL.

Step2: Calculate the number of Ativan tablets per morning

Mr. Brown takes 1.5 mg of Ativan each morning and the tablets are 1 mg per tablet. Using the formula $n=\frac{D}{d}$, where $D$ is the desired dose and $d$ is the dose per tablet. So $n=\frac{1.5}{1}=1.5$ tablets.

Step3: Calculate the total number of Eliquis tablets per day

Mr. Rybka takes Eliquis 5 mg twice - a day and the tablets are 2.5 mg each. The total daily dose is $5\times2 = 10$ mg. Using the formula $n=\frac{D}{d}$, where $D = 10$ mg and $d = 2.5$ mg. So $n=\frac{10}{2.5}=4$ tablets.

Answer:

Question 6: 1.5 mL
Question 5: 1.5 tabs
Question 4: 4 tabs
