Studdy Solution

STEP 1

1. Conversion factors are known and used accurately.
2. The problems are solved in the order they are presented.
3. For each problem, the necessary units and calculations are clearly defined.

STEP 2

1. Unit Conversion
2. Tablet Dosage Calculation
3. Injection Volume Calculation
4. Body Weight Dosage Calculation

STEP 3

Convert 0.2 grams to micrograms.
0.2 g×1,000,000 μg1 g=200,000 μg0.2 \, \text{g} \times \frac{1,000,000 \, \mu\text{g}}{1 \, \text{g}} = 200,000 \, \mu\text{g}

STEP 4

Convert 0.86 micrograms to grams.
0.86 μg×1 g1,000,000 μg=0.00000086 g0.86 \, \mu\text{g} \times \frac{1 \, \text{g}}{1,000,000 \, \mu\text{g}} = 0.00000086 \, \text{g}

STEP 5

Convert 280 pounds to kilograms.
280 lb×0.453592 kg1 lb=127.006 kg280 \, \text{lb} \times \frac{0.453592 \, \text{kg}}{1 \, \text{lb}} = 127.006 \, \text{kg}

STEP 6

Calculate the number of tablets for a single dose of 850 mg TDD in 4 divided doses with 250 mg tablets.
Single dose=850 mg4=212.5 mg\text{Single dose} = \frac{850 \, \text{mg}}{4} = 212.5 \, \text{mg} Number of tablets=212.5 mg250 mg/tablet=0.85 tablets\text{Number of tablets} = \frac{212.5 \, \text{mg}}{250 \, \text{mg/tablet}} = 0.85 \, \text{tablets}

STEP 7

Calculate the number of tablets for a daily dose of 300 mg every 4 hours with 150 mg tablets.
Total daily dose=24 hours4 hours/dose×300 mg/dose=1800 mg\text{Total daily dose} = \frac{24 \, \text{hours}}{4 \, \text{hours/dose}} \times 300 \, \text{mg/dose} = 1800 \, \text{mg} Number of tablets=1800 mg150 mg/tablet=12 tablets\text{Number of tablets} = \frac{1800 \, \text{mg}}{150 \, \text{mg/tablet}} = 12 \, \text{tablets}

STEP 8

Calculate the volume for 350 mcg of Drug X with 1 mg in 1 ml.
350 μg×1 mg1000 μg=0.35 mg350 \, \mu\text{g} \times \frac{1 \, \text{mg}}{1000 \, \mu\text{g}} = 0.35 \, \text{mg} Volume=0.35 mg1 mg/ml=0.35 ml\text{Volume} = \frac{0.35 \, \text{mg}}{1 \, \text{mg/ml}} = 0.35 \, \text{ml}

STEP 9

Calculate the volume for 0.6 mg of drug X with 0.4 mg in 2 ml.
Volume=0.6 mg0.4 mg/2 ml×2 ml=3 ml\text{Volume} = \frac{0.6 \, \text{mg}}{0.4 \, \text{mg/2 ml}} \times 2 \, \text{ml} = 3 \, \text{ml}

STEP 10

Calculate how many times too much 0.1 ml is compared to 0.01 ml.
Times too much=0.1 ml0.01 ml=10\text{Times too much} = \frac{0.1 \, \text{ml}}{0.01 \, \text{ml}} = 10

STEP 11

Calculate the single dose for a 90 kg male patient prescribed 1.5 mg/kg of drug X.
Single dose=90 kg×1.5 mg/kg=135 mg\text{Single dose} = 90 \, \text{kg} \times 1.5 \, \text{mg/kg} = 135 \, \text{mg}

STEP 12

Calculate the single dose for a 78 kg female patient prescribed 40 mg/kg of Chloramphenicol.
Single dose=78 kg×40 mg/kg=3120 mg=3.12 g\text{Single dose} = 78 \, \text{kg} \times 40 \, \text{mg/kg} = 3120 \, \text{mg} = 3.12 \, \text{g}

STEP 13

Calculate the single dose and volume for a 5-year-old, 20 kg patient prescribed 5 mcg/kg of Digoxin elixir.
a) Single dose=20 kg×5 μg/kg=100 μg\text{Single dose} = 20 \, \text{kg} \times 5 \, \mu\text{g/kg} = 100 \, \mu\text{g}
b) Volume=100 μg50 μg/ml=2 ml\text{Volume} = \frac{100 \, \mu\text{g}}{50 \, \mu\text{g/ml}} = 2 \, \text{ml}

STEP 14

Calculate the total daily dose in grams for a 67 kg patient prescribed Cephalothin at 20 mg/kg TDD.
Total daily dose=67 kg×20 mg/kg=1340 mg=1.34 g\text{Total daily dose} = 67 \, \text{kg} \times 20 \, \text{mg/kg} = 1340 \, \text{mg} = 1.34 \, \text{g}
