Question 1

Convert 23 g 178 mg to g.

Accepted Answer

Given that, 23 g 178 mg
We know that 1 g = 1000 mg
So, 23 g 178 mg = 23 + (178/1000) g = 23.178 g (converting mg to g)
Therefore, the answer is D, 23.178 g.

Question 2

The label on a vial of the pain-relief medication sufentanil reads 200 mcg/5 ml. If a medication order reads 80 mcg IV push, how many milliliters should this patient be given?

Accepted Answer

To determine the volume of medication to administer, use the formula: (desired dose ÷ concentration) = volume to administer. Here, (80 mcg ÷ (200 mcg/5 ml)) = 2 ml.

Question 3

The dosage of a certain antibiotic is determined by the weight of the patient in kilograms. A patient weighing 35 kg is given a shot of this antibiotic. Find the amount of medication, in milligrams, the patient receives if the dosage rate for this medication is 6 mg/kg.

Accepted Answer

The dosage is calculated by multiplying the patient's weight by the dosage rate: $35 \, \text{kg} \times 6 \, \text{mg/kg} = 210 \, \text{mg}$.

Question 4

A health store buys nuts in 20-kilogram containers and repackages the nuts for resale. The store packages the nuts in 125-gram bags, costing $0.04 each, and sells them for $2.50 per bag. Find the profit on a 20-kilogram container of nuts costing $155.00.

Accepted Answer

First, we need to find out how many 125-gram bags we can make from one 20-kilogram container:
20,000 grams (one container) ÷ 125 grams (per bag) = 160 bags

Next, we need to find out the total cost of the bags:
160 bags × $0.04 per bag = $6.40

Now we can find the profit:
Revenue = 160 bags × $2.50 per bag = $400
Profit = Revenue – Cost
Profit = $400 – $155 (cost of the nuts) – $6.40 (cost of the bags)
Profit = $238.60

Therefore, the best choice is B, which is $238.60 profit.

Question 5

A patient is advised to supplement her diet with 0.875 g of calcium per day. The calcium tablets she purchases contain 175 mg of calcium per tablet. How many tablets per day should the patient take?

Accepted Answer

First, we need to convert 0.875 g to mg (since the calcium content of the tablets is in mg). 0.875 g is equal to 875 mg.

To figure out how many tablets the patient should take, we need to divide the total amount of calcium needed (875 mg) by the amount of calcium in each tablet (175 mg).

875 mg ÷ 175 mg = 5

Therefore, the patient should take 5 tablets per day.

Question 6

Each teaspoon (t) of an oral suspension of ibuprofen contains 0.7 g of medication. If a patient takes 2 t of this medication three times day for two days, how many milligrams of ibuprofen has the patient received?

Accepted Answer

Each teaspoon contains 0.7g of medication = 700mg of medication.

The patient takes 2t three times a day for two days:

2t x 700mg/t x 3 times/day x 2 days = 8,400mg

Therefore, the patient has received 8,400mg of ibuprofen.

The correct answer is C.

Question 7

One glass of milk contains 35 mg of cholesterol. How many grams of cholesterol are there in 6 glasses of milk?

Accepted Answer

One glass contains 35 mg of cholesterol, so 6 glasses contain 6 * 35 = 210 mg of cholesterol. Since there are 1000 mg in a gram, 210 mg is equal to 210 / 1000 = 0.21 grams.

Question 8

Convert 8535 cm3 to liters.

Accepted Answer

To convert from cm3 to liters, you need to divide by 1000. So, 8535 cm3 ÷ 1000 = 8.535 L. The closest answer choice is D, which is 8.535 L.

Question 9

Convert 3.45 L to ml.

Accepted Answer

To convert liters to milliliters, you multiply by 1,000 (since 1 liter = 1,000 milliliters). Therefore, 3.45 liters = 3.45 * 1,000 = 3,450 milliliters.

Question 10

Convert 5399 ml to liters.

Accepted Answer

To convert milliliters to liters, we divide by 1000. 5399 ml divided by 1000 is equal to 5.399 L. Therefore, the correct choice is C.

Question 11

Convert 21 kg 652 g to kg.

Accepted Answer

To convert from grams to kilograms, we need to divide the given amount by 1000.
21 kg 652 g = 21 + 652/1000 = 21.652 kg.
Therefore, the correct answer is option B.

Question 12

A 1.22-kilogram container of Quaker Oats contains 26 servings. Find the number of grams in one serving of the oatmeal. Round to the nearest whole number.

Accepted Answer

To find the number of grams in one serving of oatmeal, we need to divide the total number of grams in the container by the number of servings:

1.22 kg = 1220 g
Number of grams per serving = 1220 g ÷ 26 = 46.923...

Rounding to the nearest whole number gives us:

Number of grams per serving ≈ 47 g

Therefore, the best choice is B.

Question 13

Convert 468 ml to cm3.

Accepted Answer

1 milliliter (ml) is equal to 1 cubic centimeter (cm3), so 468 ml is equal to 468 cm3.

Question 14

Convert 6.13 L to cm3.

Accepted Answer

1 liter is equal to 1000 cm³, so 6.13 liters is equal to 6.13 x 1000 cm³, which is 6130 cm³.

Question 15

Find the cost of three packages of ground meat weighing 450 g, 600 g, and 540 g if the price per kilogram is $8.60. Round your answer to the nearest hundredth.

Accepted Answer

First, convert the total weight of the meat to kilograms: (450g + 600g + 540g) / 1000 = 1.59 kg. Then, multiply by the price per kilogram: 1.59 kg * $8.60/kg = $13.674, which rounds to $13.67.

Question 16

The label on a bottle of atropine sulfate indicates the strength of the medication is 0.1 mg/ml. If an injection of 200 mcg of atropine sulfate is prescribed, how many milliliters of this drug should be given to the patient?

Accepted Answer

1 mg = 1000 mcg

To convert 200 mcg to mg, we divide by 1000:
200 mcg / 1000 = 0.2 mg

Next, we can use the strength of the medication to determine how many milliliters to give:
0.1 mg/ml = 1 ml/10 mg

To give 0.2 mg of atropine sulfate, we need to administer:
0.2 mg x (1 ml/10 mg) = 0.02 ml

Therefore, the answer is D) 2 ml.

Question 17

Convert 808 cm3 to ml.

Accepted Answer

To convert cm3 to ml, we simply multiply by 1 since they are the same unit. Therefore, 808 cm3 is equal to 808 ml. The correct answer is E.

Question 18

A laboratory solution contains 25 μg of solute per milliliter of solution. How many milligrams of solute would there be in 500 ml of solution?

Accepted Answer

To find the total amount of solute in milligrams, multiply the concentration (25 μg/mL) by the volume (500 mL) and convert the result from micrograms to milligrams. $25 \mu g/mL \times 500 mL = 12500 \mu g = 12.5 mg$.

Question 19

Convert 3.18 kl to L.

Accepted Answer

1 kiloliter (kl) is equal to 1,000 liters (L), so 3.18 kl is equal to 3.18 x 1,000 = 3,180 L.

Question 20

An adult is prescribed 600 mg of a medication to be taken twice a day for five days. At the end of five days, how many grams of this medication has the patient taken?

Accepted Answer

The patient is taking 600 mg of the medication twice a day, for a total of 1200 mg per day (600 mg x 2). Over the course of 5 days, the patient will have taken 6,000 mg (1200 mg x 5). To convert this to grams, we divide by 1000: 6,000 mg ÷ 1000 = 6 g. Therefore, the patient has taken 6 grams of the medication.
