To calculate the number of mLs to be given, we need to divide the ordered dose (0.75 mg) by the concentration of the available solution (0.25 mg/mL). This will give us the volume in mLs. In this case, 0.75 mg divided by 0.25 mg/mL equals 3 mLs. Therefore, the correct answer is 3 mLs.

To calculate the number of milliliters needed, divide the total number of units required (20,000) by the number of units available per milliliter (7500). This will give us the number of milliliters needed to administer the required dose. In this case, 20,000 divided by 7500 equals 2.66 ml. Therefore, the correct answer is 2.66 ml.

The correct answer is 240 cc's. A coffee cup typically holds 8 ounces of liquid. To convert ounces to cc's, we use the conversion factor of 1 ounce = 29.5735 cc's. Therefore, 8 ounces is equal to 8 * 29.5735 = 236.588 cc's. Rounded to the nearest whole number, the answer is 240 cc's.

The question asks for the conversion of milligrams (mgs) to grams. Since there are 1000 milligrams in a gram, to convert 4500 mgs to grams, we divide by 1000. Therefore, 4500 mgs is equal to 4.5 grams.

Since the question asks for the number of cc's in a 6 oz glass of orange juice, the correct answer is 180 cc's. This means that a 6 oz glass of orange juice contains 180 cubic centimeters of liquid.

To convert pounds to kilograms, you can use the following conversion factor: 1 lb = 0.453592 kg. Therefore, to convert 165 lbs to kg, you would multiply 165 by 0.453592. The result is approximately 74.842 kg. Since the answer options are rounded to the nearest whole number, the closest option to the actual conversion is 75 kg.

The available concentration of the XYZ liquid medication is 10 g per 15 ml. To calculate the amount of medication to be given, we can set up a proportion. Let x be the amount of medication to be given in ml. The proportion can be set up as 10 g / 15 ml = 20 g / x ml. Cross-multiplying and solving for x, we get x = (15 ml * 20 g) / 10 g = 30 ml. Therefore, 30 ml is the correct answer.

The available concentration of the XYZ liquid medication is 125 mg per 5 ml. To calculate the number of milliliters needed, we can set up a proportion: 125 mg/5 ml = 375 mg/x ml. Cross-multiplying and solving for x, we find that x = (375 mg * 5 ml) / 125 mg = 15 ml. Therefore, 15 ml of the XYZ liquid medication will be given.

Since 1 oz is equal to approximately 30 ml, a 6 oz tea cup would contain 6 x 30 = 180 ml. Therefore, the correct answer is 180 ml's.

The height of the patient is 84 inches, which is equivalent to 7 feet. Since there are 12 inches in a foot, the remaining 0 inches do not contribute to the height in feet. Therefore, the man is 7 feet tall.

The correct answer is 480 ml's. One ounce is equal to approximately 30 ml, so 16 ounces would be equal to 16 x 30 = 480 ml.

Based on the given information, the medication XYZ is prescribed at a dose of 1.2 grams to be taken orally every 6 hours. The available strength of XYZ is 400 mg per capsule. To calculate the number of capsules required, we need to convert the prescribed dose from grams to milligrams. Since 1 gram is equal to 1000 milligrams, the prescribed dose is equal to 1200 milligrams. Dividing the prescribed dose by the strength of each capsule (400 mg), we get 3 capsules as the answer. Therefore, 3 capsules would be given to fulfill the prescribed dose.

To calculate the number of mLs to give, we need to divide the desired dose (50 mg) by the concentration of the drug available (80 mg/mL). This will give us the volume in mLs. Therefore, 50 mg divided by 80 mg/mL equals 0.625 mLs, which is rounded to 0.62 mLs.

Since each capsule is 500 mg and the dosage required is 1 g (1000 mg), we need to take 2 capsules to achieve the required dosage.

A tablespoon is a unit of volume commonly used in cooking and is equivalent to 15 cc's. This means that there are 15 cubic centimeters in one tablespoon.

The doctor ordered Kcl elixir 40 mEq po qid, which means the patient needs to take 40 milliequivalents of Kcl orally four times a day. The available Kcl elixir is 20 mEq in 15 ml. To give 40 mEq, we can calculate the required amount by setting up a proportion: 20 mEq/15 ml = 40 mEq/x ml. Solving for x, we find that x = 30 ml. Therefore, 30 ml of the Kcl elixir will provide the required dose of 40 mEq.

The available concentration of XYZ drug is 1.5 mg per 0.5 mL. We need to administer 2 mg of the drug. To find the amount of mL needed, we can set up a proportion: 1.5 mg/0.5 mL = 2 mg/x mL. Cross-multiplying gives us 1.5x = 1, which simplifies to x = 1/1.5 = 0.67 mL. Since we need to round up, the correct answer is 0.7 mL.

The doctor ordered Kcl elixir 40 mEq po qid (four times a day) in juice. The available Kcl elixir is 20 mEq in 15 ml. To calculate the total milliliters of the drug to be given in one day, we need to multiply the number of doses (4) by the amount of drug in each dose (40 mEq) and divide it by the concentration of the drug in the available elixir (20 mEq/15 ml). This gives us (4 x 40 mEq) / (20 mEq/15 ml) = 160 ml / (20 mEq/15 ml) = 160 ml x (15 ml/20 mEq) = 160 ml x 0.75 = 120 ml. Therefore, 120 ml of the drug will be given in one day.

To calculate the total number of capsules needed, we first need to determine the total amount of medication needed for 7 days. The order is for 1 g (1000 mg) of Ampicillin every 6 hours. Since there are 24 hours in a day, this means the medication will be taken 4 times a day. So, in 1 day, the patient will require 4 capsules (4 x 500 mg = 2000 mg). For 7 days, the total amount of medication needed will be 7 x 2000 mg = 14,000 mg. Since each capsule is 500 mg, we divide 14,000 mg by 500 mg to get the total number of capsules needed, which is 28. However, since the medication is taken 4 times a day, we need to multiply 28 capsules by 4, giving us a total of 56 capsules needed.

The medication order states to give 1 1/2 gr (grain) of Phenobarbital at bedtime. The available form of the medication is 30 mg tablets. To calculate the number of tablets to be given, we need to convert the dosage from grains to milligrams. 1 grain is equivalent to approximately 64.8 milligrams. Therefore, 1 1/2 grains is approximately 97.2 milligrams. Since each tablet is 30 mg, we divide 97.2 by 30, which equals approximately 3.24. Since we cannot give a fraction of a tablet, we round up to the nearest whole number, which is 4. Therefore, the correct answer is 3- 30 mg tablets.
