Question

A nurse is preparing to administer lactated Ringer's 250 mL IV to infuse over 30 min. The nurse should set the IV pump to deliver how many mL/hr?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer 1

Correct Answers:

500

Rationale :

Identify the total volume to infuse:
250 mL
Identify the infusion time in minutes:
30 minutes
Use the formula: mL/hr=(250÷30)×60
First, divide the total volume by the number of minutes:250÷30=8.33
Then, multiply the result by 60 (to convert from per minute to per hour):8.33×60=499.8
Round to the nearest whole number:499.8 rounds to 500

Answer 2

Correct Answers:

Administer a loading dose of 100 mg PO
Administer the medication with a snack

Rationale :

Administer a loading dose of 100 mg PO

🔹 The prescription clearly states “100 mg PO now”, indicating a loading dose to quickly achieve therapeutic levels of the drug.

🔹 A loading dose is common with NSAIDs like indomethacin for immediate pain relief before starting a maintenance schedule.

🔹 After the 100 mg dose, the nurse will continue with the 50 mg PO three times a day (TID).

🔹 Administering the loading dose promptly supports early symptom control in acute pain or inflammation.

Administer the medication with a snack

🔹 Indomethacin, like other NSAIDs, can irritate the gastrointestinal lining, increasing the risk for ulcers or GI bleeding.

🔹 The prescription specifies “with food”, and giving the drug with a snack or meal helps reduce gastric upset.

🔹 If the client is not ready for a full meal, a light snack (crackers, bread, or milk) is appropriate.

🔹 This aligns with safe medication administration practices for gastroprotective care.

Answer 6

Correct Answers:

2.1

Rationale :

🧮 Step-by-Step Calculation:

1️⃣ Calculate the total daily dose:3mg×85kg=255mg/day

2️⃣ Divide the total daily dose into 3 doses:255÷3=85mg per dose

3️⃣ Use the concentration to calculate volume per dose:85÷40=2.125mL

4️⃣ Round to the nearest tenth:2.125≈2.1mL

Answer 8

Correct Answers:

0.2

Rationale :

Desired dose = 7.5 mg
Available concentration = 15 mg per 0.4 mL
Use the formula:

7.5÷15=0.57.5 ÷ 15 = 0.5

Multiply the result by 0.4 mL:

0.5×0.4=0.2 mL
