Answers & Rationales

1. Solution:

Nurse Thomas can calculate the volume to be administered using the following formula:

Volume (in mL) = Dose required (in mg) / Concentration of solution (in mg/mL)

The ordered dose is 3 mg and the available concentration of the solution is 2 mg/mL.

Substitute these values into the formula:

Volume (in mL) = 3 mg / 2 mg/mL

Now, let’s calculate the volume:

Volume = 1.5 mL

Therefore, Nurse Thomas should administer 1.5 mL of the Dilaudid solution to deliver the ordered dose of 3 mg.

2. Solution:

Nurse Emily can determine the amount of medication needed by first converting the ordered dose from grams to milligrams:

0.1 grams = 0.1 * 1000 = 100 milligrams

The available tablets on the unit are each 100 mg. Given that the dose she needs to administer is also 100 milligrams, she needs to give the patient 1 tablet to fulfill the ordered dosage.

Therefore, Nurse Emily should administer one tablet of this medication to deliver the ordered dose of 0.1 gram.

3. Solution:

Nurse Liam can determine the number of tablets needed by using the following formula:

Number of tablets = Ordered dose (in units) / Tablet strength (in units)

The ordered dose is 800,000 units and the strength of each available tablet is 400,000 units.

Substitute these values into the formula:

Number of tablets = 800,000 units / 400,000 units

Now, let’s calculate the number of tablets:

Number of tablets = 2

Therefore, Nurse Liam should administer two tablets of potassium penicillin to deliver the ordered dose of 800,000 units.

4. Solution:

Nurse Bella can determine the number of tablets needed by using the following formula:

Number of tablets = Ordered dose (in mg) / Tablet strength (in mg)

First, she needs to convert the ordered dose from grams to milligrams, since the strength of the tablets is given in milligrams:

2 grams = 2 * 1000 = 2000 milligrams

Then, substitute these values into the formula:

Number of tablets = 2000 mg / 500 mg

Now, let’s calculate the number of tablets:

Number of tablets = 4

Therefore, Nurse Bella should administer four tablets of Azulfidine to fulfill the ordered dosage of two grams.

5. Solution:

Nurse Ethan can determine the number of tablets needed using the following formula:

Number of tablets = Ordered dose (in units) / Tablet strength (in units)

The ordered dose is 1,200,000 units, and each available tablet has a strength of 400,000 units.

Substitute these values into the formula:

Number of tablets = 1,200,000 units / 400,000 units

Now, let’s calculate the number of tablets:

Number of tablets = 3

Therefore, Nurse Ethan should administer three tablets of potassium penicillin to deliver the ordered dose of 1,200,000 units.

6. Solution:

Nurse Sophia can calculate the number of tablets needed using the following formula:

Number of tablets = Ordered dose (in mcg) / Tablet strength (in mcg)

First, she needs to convert the ordered dose from milligrams (mg) to micrograms (mcg), since the strength of the tablets is given in micrograms. There are 1,000 micrograms in a milligram, so:

1.25 mg = 1.25 * 1000 = 1250 mcg

Then, she substitutes these values into the formula:

Number of tablets = 1250 mcg / 625 mcg

Now, let’s calculate the number of tablets:

Number of tablets = 2

Therefore, Nurse Sophia should administer two tablets of Premarin to fulfill the ordered dosage of 1.25 mg.

7. Solution:

Nurse Noah can determine the number of tablets needed by using the following formula:

Number of tablets = Ordered dose (in mg) / Tablet strength (in mg)

First, he needs to convert the ordered dose from grams to milligrams, as the strength of the tablets is given in milligrams:

1.5 grams = 1.5 * 1000 = 1500 milligrams

Then, he substitutes these values into the formula:

Number of tablets = 1500 mg / 500 mg

Now, let’s calculate the number of tablets:

Number of tablets = 3

Therefore, Nurse Noah should administer three tablets of Azulfidine to fulfill the ordered dosage of 1.5 grams.

8. Solution:

To convert the order from grains to milligrams, Nurse Jack can use the conversion factor that 1 grain is approximately equal to 64.8 milligrams.

So, the ordered dose in milligrams can be calculated as:

Ordered dose (in mg) = Ordered dose (in grains) * Conversion factor (in mg/grain)

Let’s substitute these values into the formula:

Ordered dose (in mg) = 1.5 grains * 64.8 mg/grain

Ordered dose = 97.2 mg

The available Sodium Seconal capsules each contain 100 mg. Given that the calculated dose is 97.2 mg, which is very close to 100 mg, Jack will need to give the patient 1 capsule to meet the ordered dose.

Therefore, Nurse Jack should administer one capsule of Sodium Seconal to deliver the ordered dose of 1 ½ grains. Please note that this approximation should be verified with the prescriber or a pharmacist, as it slightly exceeds the ordered dose.

9. Solution:

Hint: First, convert the ordered dose from grams to milligrams, knowing that 1 gram equals 1000 milligrams. Then, determine the number of tablets that will provide the correct dose based on the strength of the available medication.

Nurse Jenna can calculate the number of tablets needed using the following formula:

Number of tablets = Ordered dose (in mg) / Tablet strength (in mg)

First, she needs to convert the ordered dose from grams to milligrams, as the strength of the tablets is given in milligrams:

0.05 grams = 0.05 * 1000 = 50 milligrams

Then, she substitutes these values into the formula:

Number of tablets = 50 mg / 50 mg

Now, let’s calculate the number of tablets:

Number of tablets = 1

Therefore, Nurse Jenna should administer one tablet of Imipramine HCL to fulfill the ordered dosage of 0.05 grams.

10. Solution:

Nurse Eli can calculate the number of tablets needed using the following formula:

Number of tablets = Ordered dose (in mcg) / Tablet strength (in mcg)

First, he needs to convert the tablet strength from milligrams (mg) to micrograms (mcg) since the ordered dose is given in micrograms. There are 1000 micrograms in a milligram, so:

0.2 mg = 0.2 * 1000 = 200 mcg

Then, he substitutes these values into the formula:

Number of tablets = 200 mcg / 200 mcg

Now, let’s calculate the number of tablets:

Number of tablets = 1

Therefore, Nurse Eli should administer one tablet of Ergotrate maleate to fulfill the ordered dosage of 200 mcg.
