Question

The client has an order for atropine 100 mcg subcutaneously. The medication available is atropine 1 mg/0.7 mL. How many mL will the nurse administer? (If needed, round to the nearest tenth.)

Answer 1

Correct Answers:

0.1

Rationale :

💉The prescribed atropine dose is 100 mcg, while the available concentration is 1 mg/0.7 mL.

🔄Convert 100 mcg to 0.1 mg so the ordered dose and available dose use the same unit.

💁‍♂️Using the dosage formula, 0.1 mg ÷ 1 mg × 0.7 mL = 0.07 mL.

🎯Rounding 0.07 mL to the nearest tenth gives 0.1 mL for administration.

📌Core Message

The ordered dose must first be converted to the same unit as the available concentration before calculating the correct medication volume.

Answer 2

Correct Answers:

0.5

Rationale :

💊The prescribed digoxin dose is 125 mcg, while each scored tablet contains 0.25 mg.

🔁Convert 125 mcg to 0.125 mg before performing the calculation.

👉The required amount is 0.125 mg ÷ 0.25 mg × 1 tablet = 0.5 tablet.

✂️Because the medication is supplied as a scored tablet, administering one-half tablet is appropriate.

📌Core Message

A scored tablet permits accurate administration of a half-tablet dose after the medication units have been correctly converted.

Answer 3

Correct Answers:

0.8

Rationale :

💉The prescribed cyanocobalamin dose is 250 mcg, while the available medication contains 0.3 mg/mL.

💁‍♂️Convert 250 mcg to 0.25 mg to match the available concentration.

💪Calculate the volume as 0.25 mg ÷ 0.3 mg × 1 mL = 0.833 mL.

🎯Rounding 0.833 mL to the nearest tenth gives 0.8 mL.

📌Core Message

Accurate unit conversion followed by nearest-tenth rounding determines the correct injectable cyanocobalamin volume.

Answer 4

Correct Answers:

18

Rationale :

🧴The prescribed amoxicillin dose is 0.45 g, while the suspension provides 125 mg in 5 mL.

🔄Convert 0.45 g to 450 mg before calculating the liquid volume.

💎The required volume is 450 mg ÷ 125 mg × 5 mL = 18 mL.

🤙Because the question requests the nearest whole milliliter, the final amount remains 18 mL.

📌Core Message

Converting grams to milligrams allows the liquid concentration to be used correctly to determine the administration volume.

Answer 5

Correct Answers:

0.5

Rationale :

💧The prescribed furosemide dose is 5 mg, while the vial contains 10 mg/mL.

👉The volume required is 5 mg ÷ 10 mg × 1 mL = 0.5 mL.

💉This calculation shows that half of one milliliter supplies the prescribed dose.

🎯The result already contains the required nearest-tenth precision, so no additional rounding is necessary.

📌Core Message

When the ordered dose is one-half of the available milligram concentration, the administered volume is one-half of the stated milliliter amount.

Answer 6

Correct Answers:

0.7

Rationale :

💉The prescribed meperidine dose is 35 mg, while the medication contains 50 mg/mL.

💢Calculate the required amount as 35 mg ÷ 50 mg × 1 mL = 0.7 mL.

📐The calculated volume is already expressed to the required nearest tenth of a milliliter.

✅Therefore, the nurse should prepare 0.7 mL of meperidine for the IM injection.

📌Core Message

The correct IM medication volume is obtained by comparing the prescribed dose with the concentration available in each milliliter.

Answer 7

Correct Answers:

1.4

Rationale :

⚖️The client weighs 242 lb, so the weight must first be converted to kilograms for the weight-based prescription.

🔄Calculate 242 lb ÷ 2.2 = 110 kg, making the prescribed enoxaparin dose 110 mg because the order is 1 mg/kg.

💉Using the available concentration, 110 mg ÷ 80 mg × 1 mL = 1.375 mL.

🎯Rounding 1.375 mL to the nearest tenth gives 1.4 mL.

📌Core Message

Safe weight-based enoxaparin dosing requires conversion from pounds to kilograms before calculating the injectable volume.

Answer 8

Correct Answers:

1.5

Rationale :

💊The prescribed hydrochlorothiazide dose is 37.5 mg, while each scored tablet contains 25 mg.

👉Calculate the number of tablets as 37.5 mg ÷ 25 mg × 1 tablet = 1.5 tablets.

✂️The presence of a scored tablet allows the nurse to administer a half-tablet accurately.

💪Therefore, the prescribed dose requires one and one-half tablets.

📌Core Message

A scored hydrochlorothiazide tablet can be divided accurately to provide a dose requiring one whole tablet plus one-half tablet.

Answer 9

Correct Answers:

1

Rationale :

💊The prescribed metformin dose is 0.5 g, while the available tablet contains 500 mg.

🔄Convert 0.5 g to 500 mg so both medication quantities use the same unit.

👉The required amount is 500 mg ÷ 500 mg × 1 tablet = 1 tablet.

💪Because the ordered dose matches the tablet strength exactly, one tablet provides the full prescribed dose.

📌Core Message

When the converted prescribed dose matches the available tablet strength, a single tablet provides the required medication amount.

Answer 10

Correct Answers:

3

Rationale :

💊The prescribed sulfasalazine dose is 1.5 g, while each tablet contains 500 mg.

👉Convert 1.5 g to 1,500 mg before calculating the number of tablets.

💁‍♂️The tablet quantity is 1,500 mg ÷ 500 mg × 1 tablet = 3 tablets.

💪Because the result is already a whole-number tablet quantity, no further rounding is needed.

📌Core Message

Correct gram-to-milligram conversion shows how many 500-mg tablets are necessary to supply the prescribed sulfasalazine dose.
