When 250 mg of a medication is diluted in 500 mL of 5% dextrose in water, how many milligrams of the medication will be in 1 mL of D5W?

0.5.

50.

500.

Answer and Explanation

The Correct Answer is D

The question asks how many milligrams of the medication will be in 1 mL of D5W. To find this, we need to know the concentration of the medication in the solution.

Concentration is the amount of medication per unit volume of solution. We can use this formula:

Concentration = Mass / Volume

We know that 250 mg of the medication is diluted in 500 mL of D5W. So we can plug these values into the formula:

Concentration = 250 mg / 500 mL Simplifying, we get:

Concentration = 0.5 mg / mL

This means that there are 0.5 mg of the medication in every 1 mL of D5W. So the answer is

To check our answer, we can use another formula:

Mass = Concentration x Volume

If we want to find the mass of the medication in 1 mL of D5W, we can multiply the concentration by the volume:

Mass = 0.5 mg / mL x 1 mL Simplifying, we get:

Mass = 0.5 mg

This matches our answer.

The other choices are wrong because they do not use the correct formula or values. Here is why:

Choice A is wrong because it uses the inverse of the concentration (1 / 0.5) instead of the concentration (0.5).

Choice B is wrong because it uses the mass of the medication (250 mg) instead of the concentration (0.5 mg / mL).

Correct Answer is A

Explanation

This is because aspirin can cause gastrointestinal bleeding, ulceration, and perforation as side effects. Tarry-colored stools indicate the presence of blood in the stool, which is a sign of bleeding in the upper gastrointestinal tract.

This is a serious condition that requires immediate medical attention.

Choice B. Swelling of the leg and knee is wrong because it is not related to aspirin use.

It may indicate inflammation, infection, or injury of the leg and knee, but it is not a priority symptom to report to the HCP.

Choice C. Right upper quadrant discomfort is wrong because it is not related to aspirin use.

It may indicate liver or gallbladder problems, but it is not a priority symptom to report to the HCP.

Choice D. Bruising around the injured knee is wrong because it is not related to aspirin use.

It may indicate trauma, bleeding disorders, or coagulation problems, but it is not a priority symptom to report to the HCP.

Normal ranges for bleeding time are 2 to 7 minutes. Normal ranges for PTT are 25 to 35 seconds. Normal ranges for liver enzymes are AST 10 to 40 U/L and ALT 7 to 56 U/L.

A. Chicken, carrots, and fresh grapefruit salad. B. Salmon, turnip greens, brown rice, and an orange. C. Green salad, ground beef patty, corn, and applesauce. D. Plain omelet, bacon, toast with butter, and strawberries.

Correct Answer is B

Explanation

This meal selection best demonstrates a client with osteoporosis understands dietary recommendations because it provides adequate amounts of calcium, vitamin D, and protein, which are essential nutrients for bone health.

Choice A is wrong because chicken, carrots, and fresh grapefruit salad do not provide enough calcium or vitamin D for a person with osteoporosis.

Calcium is mainly found in dairy products, leafy green vegetables, and fish with bones. Vitamin D is mainly found in fatty fish, egg yolks, and fortified foods.

Choice C is wrong because green salad, ground beef patty, corn, and applesauce do not provide enough calcium or vitamin D for a person with osteoporosis.

Green salad may contain some calcium depending on the type of greens, but it is not a rich source.

Ground beef patty and corn are low in calcium and vitamin

D. Applesauce does not contain any calcium or vitamin

D. Choice D is wrong because plain omelet, bacon, toast with butter, and strawberries do not provide enough calcium or vitamin D for a person with osteoporosis.

Plain omelet and bacon are high in protein but low in calcium and vitamin

Toast with butter may contain some vitamin D if the bread or butter are fortified, but it is not a rich source.

Strawberries do not contain any calcium or vitamin
