The physician orders Ferrous Sulfate 500 mg po qd x 30 days, and the available concentration is Ferrous Sulfate 220 mg/5ml 473 ml. To find the required ml for one dose, we can use the following calculation: (500 mg / 220 mg) * 5 ml = 11.4 ml. This calculation takes into account the desired dose of 500 mg and the concentration of the available medication, resulting in 11.4 ml as the required amount for one dose.

The infusion rate is calculated by dividing the desired dose (50 mg) by the concentration of the drug in the IV (5 mg/ml). This gives us 10 ml/hr, which means that the patient needs to receive 10 ml of the IV solution every hour in order to receive the desired dose of 50 mg per hour.

To find the number of tablets that should be dispensed, we need to convert the prescribed amount of amoxicillin from liquid form to tablet form. The original prescription was for 150 ml of amoxicillin 250 mg/5ml. This means that each 5 ml of liquid contains 250 mg of amoxicillin. To find the total amount of amoxicillin in the prescription, we can set up a proportion: 5 ml is to 250 mg as 150 ml is to x mg. Solving this proportion, we find that x = (150 ml * 250 mg) / 5 ml = 7500 mg. Since each chewable tablet contains 250 mg of amoxicillin, the number of tablets that should be dispensed is 7500 mg / 250 mg = 30 tablets.

Since there are 128 fluid ounces in a gallon, dividing 128 by 4 gives us 32. Therefore, a gallon of Coke Syrup can fill 32 four-ounce bottles.

The correct answer is 1.4 ml/minute. To calculate the infusion rate in ml per minute, we divide the total volume (1000 ml) by the total time (12 hours = 720 minutes). Therefore, 1000 ml / 720 minutes = 1.4 ml/minute.

To calculate the number of tablets needed to fill the order completely, we need to find the total amount of Metronidazole required. The prescription states that the concentration of Metronidazole is 250 mg/5 ml. Since the total volume needed is 240 ml, we can calculate the total amount of Metronidazole required as follows: 240 ml * (250 mg/5 ml) = 12,000 mg.

Since each tablet contains 500 mg, we can divide the total amount required by the amount in each tablet: 12,000 mg / 500 mg = 24 tablets. Therefore, 24 tablets will be needed to fill this order completely.

To find the number of teaspoons needed for the required dose, we can set up a proportion. Since the drug is available as 400 mg/5 ml, we can set up the proportion as 400 mg/5 ml = 500 mg/x tsp. Cross-multiplying gives us 400x = 5 * 500, which simplifies to 400x = 2500. Dividing both sides by 400 gives us x = 2500/400, which equals 6.25. Since there are 5 ml in 1 teaspoon, we divide 6.25 by 5 to get 1.25 tsp. Therefore, 1.25 tsp is needed for the required dose.

To find the amount of concentrated vial needed to add to the IV bag, we can use the formula:

Amount of concentrated vial = (Desired dose / Concentration of vial) * Volume of IV bag

In this case, the desired dose is 45 mEq, the concentration of the vial is 4.4 mEq/ml, and the volume of the IV bag is 1000 ml.

Plugging in the values, we get:

Amount of concentrated vial = (45 mEq / 4.4 mEq/ml) * 1000 ml = 1022.73 ml

Since we have a 50 ml vial, we need to round up to the nearest whole number, giving us 1030 ml. However, since we only have 50 ml available, we can only add 50 ml of the concentrated vial to the IV bag. Therefore, the correct answer is 10.2 ml.

The patient is taking 2 teaspoons of sucralfate suspension four times a day. To calculate how much suspension the patient will use in 72 hours, we need to determine the total amount used in one day and then multiply it by 3 since 72 hours is equivalent to 3 days. Since the patient takes 2 teaspoons four times a day, the total amount used in one day is 2 teaspoons x 4 = 8 teaspoons. In 72 hours, the patient will use 8 teaspoons x 3 = 24 teaspoons. Since 1 ounce is equivalent to 6 teaspoons, the patient will use 24 teaspoons / 6 = 4 ounces of suspension in 72 hours. Therefore, the answer is 4 oz.

To convert Fahrenheit to Celsius, you can use the formula: C = (F - 32) / 1.8. In this case, the temperature in Fahrenheit is 46. Using the formula, we can calculate the temperature in Celsius as follows: C = (46 - 32) / 1.8 = 14 / 1.8 = 7.8. Therefore, the temperature in Celsius is 7.8°C.

The concentration of dextrose in the resulting solution is 20%. This can be calculated by dividing the amount of dextrose in the solution (40 ml) by the total volume of the solution (100 ml) and multiplying by 100. Therefore, (40 ml / 100 ml) * 100 = 40%.

The conversion factor for grams to milligrams is 1000, which means that there are 1000 milligrams in 1 gram. To convert 5 grams to milligrams, we multiply 5 by 1000, resulting in 5000 milligrams.

To calculate the number of ounces of meds needed to last 8 days, we need to determine the total amount of medication consumed per day and then multiply it by the number of days. The dose of meds is one and one-half teaspoonsfuls four times a day.

One and one-half teaspoonsfuls is equivalent to 3/2 teaspoonsfuls.

So, the total amount of meds consumed per day is 3/2 teaspoonsfuls * 4 times = 6 teaspoonsfuls.

Since 1 teaspoonful is approximately 0.17 ounces, the total amount of meds consumed per day is 6 * 0.17 ounces = 1.02 ounces.

Therefore, for 8 days, the total amount of meds needed is 1.02 ounces * 8 days = 8.16 ounces.

Rounding it up to the nearest whole number, we get 8 ounces.

The temperature in the refrigerator is given as 45º F. To convert this to Celsius, we use the formula C = (F - 32) * 5/9. Plugging in the given temperature, we get C = (45 - 32) * 5/9 = 13 * 5/9 = 65/9 ≈ 7.22. Rounding to the nearest whole degree, the temperature in Celsius is 7º Centigrade.

The physician has ordered Ferrous Sulfate 500 mg to be taken orally once daily for 30 days. The available form of Ferrous Sulfate on the shelf is 220 mg/5ml with a total volume of 473 ml. To find out how many ml are required to completely fill this prescription, we can set up a proportion. 500 mg is to 1 day as X ml is to 473 ml. Solving this proportion, we can find X. Cross-multiplying, we get 500 * 473 = 1 * X. Simplifying, X = 236,500 / 1 = 236,500 ml. Therefore, approximately 342 ml are required to completely fill this prescription.

The ampule of digoxin injection contains 500 mcg in 2 ml. To deliver a dose of 0.125 mg, we need to convert the dose to mcg. 0.125 mg is equal to 125 mcg. Since the concentration of the ampule is 500 mcg in 2 ml, we can set up a proportion to find the volume needed.

(125 mcg / 500 mcg) = (x ml / 2 ml)

Cross-multiplying and solving for x, we get:

125 mcg * 2 ml = 500 mcg * x ml
250 mcg = 500 mcg * x ml
x ml = 250 mcg / 500 mcg
x ml = 0.5 ml

Therefore, the volume needed to deliver a dose of 0.125 mg is 0.5 ml.

The correct answer is 105 ml. This can be determined by using the final concentration of the suspension and the desired volume. The final concentration is given as 250 mg/5ml, which means that for every 5 ml of suspension, there is 250 mg of the antibiotic. The desired volume of the suspension is 150 ml. To find the powder volume, we can set up a proportion: (250 mg/5 ml) = (x mg/150 ml). Solving for x, we find that x = 105 ml, which is the powder volume needed.
