tablets are 700 mcg each. the patient needs 1.4 mg of this drug. how many tablets do you give?
answer:

Explanation:

Question 7

Step1: Convert grams to milligrams

We know that \(1\space g = 1000\space mg\), so \(0.5\space g=0.5\times1000 = 500\space mg\).

Step2: Calculate the number of tablets

Let the number of tablets be \(n\). Each tablet is \(25\space mg\), so \(n=\frac{500}{25}\).

Step1: Convert milligrams to micrograms

We know that \(1\space mg = 1000\space mcg\), so \(0.4\space mg = 0.4\times1000=400\space mcg\). The concentration is \(400\space mcg/10\space mL\), which simplifies to \(40\space mcg/mL\).

Step2: Calculate the volume

Let the volume be \(V\). We have \(V=\frac{50}{40}\times10\) (first find out how many mL per mcg from the concentration and then multiply by the ordered mcg). Wait, another way: The concentration is \(0.4\space mg/10\space mL = 400\space mcg/10\space mL=40\space mcg/mL\). So \(V=\frac{50\space mcg}{40\space mcg/mL}=1.25\space mL\). Wait, let's do it step by step.
First, the available is \(0.4\space mg\) in \(10\space mL\), which is \(400\space mcg\) in \(10\space mL\). So per mL, it's \(\frac{400}{10} = 40\space mcg/mL\). The order is \(50\space mcg\). So the volume \(V=\frac{50}{40}=1.25\space mL\).

Step1: Convert milligrams to micrograms

We know that \(1\space mg = 1000\space mcg\), so \(1.4\space mg=1.4\times1000 = 1400\space mcg\).

Step2: Calculate the number of tablets

Let the number of tablets be \(n\). Each tablet is \(700\space mcg\), so \(n = \frac{1400}{700}\).

Answer:

\(20\)
