1.a newborn weighs 3,000 g. what is his weight in kilograms?
2.a newborn weighs 3,000g. what is his weight in pounds?
3.a stock bottle contains 2.5 liters of solution how many 2oz bottles can be filled using this solution?
4.you need to give 6mg of a drug. the drug on hand has a concentration of 24mg per ounce. how many teaspoons will you give?
5.A prescription needs to be prepared:6tsp cherry syrup. 6 oz lidocaine, 200 ml diphenhydramine.what is the final voulume in ml?
just drag out your conversion factors:
#1: 3000g * 1kg/1000g = 3kg
#2: 3000g * 1lb/454g = 6.6lb
#3: 2.5L * 1000ml/L * 1oz/30ml * 1bottle/2oz = 41.6 = 41 bottles
#4: 6mg * 1oz/24mg * 6tsp/oz = 1.5 tsp
#5:
cherry: 6tsp * 5ml/tsp = 30ml
lidocaine: 6 oz * 6tsp/oz * 5ml/tsp = 180ml
diblah: 200ml
total volume is thus 30+180+200 = 410ml
A prescription needs to be prepared: 6 tsp cherry syrup, 6 oz lidocaine, 200 ml diphenhydramine. . How many days will this solution last?
A doctor writes a prescription for 20 mg of Tobramycin antibiotic saline solution. The solution is to be injected intravenously one time a day. On hand we have a 30 mg/2 ml vial of Tobramycin.
1.3ml
1. To convert grams to kilograms, divide the weight in grams by 1000.
So, to find the weight of a newborn in kilograms, divide 3000 grams by 1000: 3000g / 1000 = 3 kilograms.
Therefore, the newborn weighs 3 kilograms.
2. To convert grams to pounds, divide the weight in grams by 453.59237.
So, to find the weight of a newborn in pounds, divide 3000 grams by 453.59237: 3000g / 453.59237 = 6.61386786 pounds (rounded to the nearest hundredth).
Therefore, the newborn weighs approximately 6.61 pounds.
3. To calculate the number of 2 oz bottles that can be filled using a 2.5 liter solution, we need to convert liters to ounces and then divide.
Since there are approximately 33.814 ounces in a liter, multiply 2.5 liters by 33.814 to get the volume in ounces: 2.5 liters * 33.814 = 84.535 ounces (rounded to the nearest thousandth).
Now, divide the volume in ounces by 2 (since each bottle is 2 oz): 84.535 ounces / 2 oz = 42.2675 bottles (rounded to the nearest tenth).
Therefore, you can fill approximately 42.3 bottles.
4. To determine how many teaspoons of a drug need to be given, we need to calculate the volume of the drug that contains 6mg and then convert it to teaspoons.
Since the concentration of the drug is 24mg per ounce, divide 6mg by 24mg/ounce to find out how many ounces are needed: 6mg / 24mg/ounce = 0.25 ounces.
Now, convert ounces to teaspoons. There are approximately 6 teaspoons in an ounce, so multiply 0.25 ounces by 6 to get the volume in teaspoons: 0.25 ounces * 6 tsp/ounce = 1.5 teaspoons.
Therefore, you need to give 1.5 teaspoons of the drug.
5. To find the final volume in milliliters, we need to convert teaspoons and ounces to milliliters and add everything together.
- 6 teaspoons of cherry syrup: There are approximately 5 milliliters in a teaspoon, so multiply 6 teaspoons by 5 to get the volume in milliliters: 6 tsp * 5 ml/tsp = 30 milliliters.
- 6 ounces of lidocaine: Multiply 6 ounces by approximately 29.5735 milliliters (the conversion factor for ounces to milliliters) to get the volume in milliliters: 6 oz * 29.5735 ml/oz = 177.441 milliliters.
- 200 milliliters of diphenhydramine: No conversion is needed.
Now, add up the volumes: 30 milliliters + 177.441 milliliters + 200 milliliters = 407.441 milliliters.
Therefore, the final volume is approximately 407.441 milliliters.
