Answer :
Where the above are given,
10. The nurse should give 2.45ml of the liquid medication.
11. The nurse can give 24ml of meperidine in 24 hours.
12. The patient should take 42 tablets of the antibiotic.
13. The IV rate is 100ml/hr at 1500gtt/min with a 15gtt/ml drip factor.
14. Each dose of codeine contains 15000mg.
15. The patient should be given 2.67oz (approximately) of the cough syrup.
What is the explanation for the above ?
10. To determine how much of the liquid should be given, we can set up a proportion
1g/3.5ml = 700mg/x
Cross-multiplying,
1g * x = 700mg * 3.5ml
x = (700mg * 3.5ml) / 1g
x = 2450mg*ml/g
Therefore, the amount of liquid to be given is 2.45ml.
11. The order states meperidine 75mg IM every 6 hours PRN pain, and the pharmacy sends a vial that contains 25mg/2ml. To calculate how many ml can be given in 24 hours, we need to consider the frequency and duration.
In 24 hours, there are 24/6 = 4 doses to be given. Each dose contains 75mg of meperidine.
To find the volume (ml) of each dose, we can set up a proportion -
25mg/2ml = 75mg/x
25mg * x = 75mg * 2ml
x = (75mg * 2ml) / 25mg
x = 6ml
12. To calculate the number of tablets the patient should take, we need to consider the dosage and the duration.
Each tablet contains 250mg of the antibiotic.
To find the number of tablets for the total dosage, we can set up a proportion -
250mg/1 tab = 0.75g/x
250mg * x = 0.75g * 1 tab
x = (0.75g * 1 tab) / 250mg
x = 0.003 tab
Since we cannot take a fraction of a tablet, the patient should take 1 tablet every 4 hours for 7 days, resulting in a total of 1 * 6 * 7
= 42 tablets.
13. To determine the IV rate, we need to calculate the number of drops per minute.
The formula to calculate the IV rate in drops per minute (gtt/min) is -
IV rate (ml/hr) = Total volume (ml) / Total time (hr)
IV rate (gtt/min) = IV rate (ml/hr) * Drop factor (gtt/ml)
IV rate (ml/hr) = 1000ml / 10hr = 100ml/hr
IV rate (gtt/min) = 100ml/hr * 15gtt/ml =
1500gtt/min
Therefore, the IV rate is 100ml/hr at 1500gtt/min.
14. To determine the amount of milligrams of codeine in each dose, we need to convert grams to milligrams.
1 gram (g) = 1000 milligrams (mg)
15 grams (gr) = 15 * 1000mg = 15000mg
Therefore, each dose contains 15000mg of codeine.
15. To calculate how much cough syrup should be given in ml's, we can set up a proportion -
225mg/1oz = x ml/600mg
225mg * x = 1oz * 600mg
x = (1oz * 600mg) / 225mg
x = 2.67oz
Therefore, 2.67oz of cough syrup should be given in ml's.

The answers to the dosage calculations for the provided medical orders are 2.45ml of the liquid ampicillin, a total of 24ml of meperidine in 24 hours, and 3 tablets of the antibiotic at each dose.
The ability to convert between different units is a crucial skill in medicine, particularly when calculating medication dosages. Here are the solutions to the medication dosage calculations:
For the order of 700mg of ampicillin PO, the drug is supplied in liquid form as 1g/3.5ml: To find the necessary volume, we set up a proportion where 1g (which is 1000mg) is to 3.5ml as 700mg is to x ml. Solving this, x equals (700mg * 3.5ml) / 1000mg, which is 2.45ml.
For meperidine 75mg IM every 6 hours PRN pain, and a vial labeled 25mg/2ml: To find out how much the nurse can give in 24 hours, first, calculate the number of doses in 24 hours, which is 24 hours divided by 6 hours (4 doses).
For each dose, the nurse needs 75mg, so for one dose, that is (75mg * 2ml) / 25mg, which is 6ml.
Over 24 hours, it totals to 6ml multiplied by 4 doses, equaling 24ml.
To give 0.75g of an antibiotic PO every 4 hours for 7 days with 250mg tablets: First convert 0.75g to mg, which is 750mg.
Now, to calculate the number of tablets, divide 750mg by 250mg/tablet, which gives us 3 tablets.
