• figure 4.10

portion of a physician’s order sheet.

1. a patient is drinking \\(\frac{1}{2}\\) pint of orange juice every two hours. at this rate, how many quarts of orange juice will the patient drink in eight hours?
2. an infant weighs 3,400 grams. how much does the infant weigh in kilograms?
3. \\(5\\,ft = \underline{\quad\quad\quad}\\ in\\)

Explanation:

Step1: Identify per-tablet mg dose

From the label, 1 tablet = 0.025 mg

Step2: Calculate 2 tablets' dose

$0.025 \times 2 = 0.05$ mg

Step1: Identify dose in mg

Order is 50 mg of chlorpromazine

Step2: Convert mg to grams

Since $1\ \text{gram} = 1000\ \text{mg}$, $\frac{50}{1000} = 0.05$ g

Step1: Find total pints consumed

Every 2 hours: $\frac{1}{2}$ pint. In 8 hours: $\frac{8}{2} = 4$ intervals. Total pints: $4 \times \frac{1}{2} = 2$ pints

Step2: Convert pints to quarts

Since $1\ \text{quart} = 2\ \text{pints}$, $\frac{2}{2} = 1$ quart

Step1: Convert grams to kilograms

Since $1\ \text{kilogram} = 1000\ \text{grams}$, $\frac{3400}{1000} = 3.4$ kg

Answer:

0.05 mg
