#### How much cocabutter is needed to distribute 12 tannic acid suppositories, each weighing 2 gm and containing 400 mg of tannic acid?

Correct!
Wrong!

We’d like to give out 12 suppositories, each weighing 2 grams and containing 400 milligrams of tannic acid:

Amount of coca butter = 2 gm x 12

= 24 gm

Amount of tannic acid = 0.4 gm x 12

= 4.8 gm.

Tannic acid has a displacement value of 0.9, so:

= 4.8/0.9 = 5.33 gm of base will displace

4.8 gm tannic acid = 5.33 gm cocabutter

Coca butter quantity = 24 gram – 5.33 gm

= 18.67 gm

#### How many 250 mg/100cc ready infusion-bags are required to satisfy the above request if the drug’s dose is 10 mg/kg/day? The patient is 156 pounds.

Correct!
Wrong!

Because the patient’s weight is 156 pounds, the weight in kilograms is 156/2.2 = 70.9 kilograms.

A usual medically recommended dose of medication is 10mg/kg/day, hence the dose in the patient mentioned above is 10mg/kg/day.

= 10 x 70.9

= 709 mg

Because each ready-infusion-bag contains 250 mg of medication, the total number of bags needed to satisfy an order is:

= 709/250 = 2.83 = 3 bags.

#### Which of the following Roman symbols represents 1,416?

Correct!
Wrong!

M = 1,000; C = 100; D = 500; X = 10; V = 5; I = 1

When a smaller Roman numeral is placed before a higher Roman numeral, the subtraction steps are always performed first:

CD = (100 taken from 500) = 400

The rest is addition: M (1,000) + CD (400) + XVI (16) = 1,416

#### What is the likelihood of failure if the probability of success in the Null hypothesis is 0.6?

Correct!
Wrong!

In the Null hypothesis, the total of the probabilities of success and failure equals 1 and can be represented using the following formula:

p + q = 1, where p is the chance of success and q is the probability of failure.

q = probability of failure

q = 1 – p

= 1- 0.6

= 0.4

#### Calculate the ratio strength of 0.4 percent.

Correct!
Wrong!

0.4 percent is the same as 0.4 percent of a hundred.

As a result, dividing 100 by 0.4 (which equals 250) yields the ratio strength of 1: 250. (Modafinil)

Extra credit: see if you can translate 0.7 percent to a ratio strength!
