question 9 (4 points)
a syrup used to treat a child’s allergies contains 2 mg of antihistamine in a 15 ml dose. how many total mg of antihistamine would be contained in a 120 ml bottle of this syrup? (4 pts)

Explanation:

Question 7

Step1: Identify the required and available dose

The ordered dose per administration is 50 mg, and each tablet is 100 mg.

Step2: Calculate the number of tablets per dose

To find the number of tablets, we divide the ordered dose by the dose per tablet. So, the number of tablets \(=\frac{50\space mg}{100\space mg/tablet}\)
\(=\frac{50}{100}= 0.5\) tablet.

Step1: Find the number of tablets per dose

The ordered dose per administration is 5 mg, and each tablet is 2.5 mg. So, tablets per dose \(=\frac{5\space mg}{2.5\space mg/tablet}= 2\) tablets per dose.

Step2: Find the number of doses in 7 days

Since the medication is taken BID (twice a day), the number of doses in 7 days \(= 2\times7 = 14\) doses.

Step3: Calculate the total number of tablets

Total tablets \(=\) tablets per dose \(\times\) number of doses \(= 2\times14=28\) tablets.

Step1: Find the number of 15 mL doses in 120 mL

First, find how many 15 mL doses are in 120 mL. The number of doses \(=\frac{120\space mL}{15\space mL/dose}= 8\) doses.

Step2: Calculate the total amount of antihistamine

Each dose has 2 mg of antihistamine, so total antihistamine \(= 2\space mg/dose\times8\space doses = 16\space mg\)

Answer:

D. 0.5 tablet
