tabs
question 5
you are to give 750,000 units. the bottle is labelled 1,000,000 units/5 ml. how many ml do you give?
answer:
question 6
the order is for 0.375 mg of a drug. the available drug reads 0.25 mg per tablet. how many tablets will you give the patient?

Explanation:

Question 4

Step1: Convert units to be consistent

We know that \(1\space g = 1000\space mg\). The order is \(500\space mg\) and each tablet is \(1000\space mg\) (since it's \(1\space g\) per tablet).

Step2: Calculate number of tablets

Let \(x\) be the number of tablets. We set up the proportion: \(\frac{500\space mg}{1000\space mg} = \frac{x}{1}\). Solving for \(x\), we get \(x=\frac{500}{1000}=0.5\).

Step1: Find the concentration per mL

The bottle is labeled \(1,000,000\) units/\(5\space mL\), so the concentration per mL is \(\frac{1,000,000\space units}{5\space mL}=200,000\space units/mL\).

Step2: Calculate volume for 750,000 units

Let \(V\) be the volume in mL. We know that \(200,000\space units/mL\times V = 750,000\space units\). Solving for \(V\), we get \(V=\frac{750,000}{200,000}=3.75\space mL\).

Step1: Set up the proportion

Let \(x\) be the number of tablets. The available drug is \(0.25\space mg\) per tablet and we need \(0.375\space mg\). So we have \(\frac{0.375\space mg}{0.25\space mg}=\frac{x}{1}\).

Step2: Solve for \(x\)

\(x = \frac{0.375}{0.25}=1.5\).

Answer:

\(0.5\) tabs
