This question-specific review guide is tied to the answer reasoning for a PracticeTestVault item. Use it after you answer the question so the review stays focused on what the prompt actually tested.
What this question is testing
Objective: IV Calculations
Prompt focus: An IV order is for 1,000 mL of D5W to infuse over 8 hours. What is the rate in mL/hr?
Why the correct answer works
125 mL/hr
1,000 / 8 = 125 mL/hr.
Why the tempting wrong answer fails
Incorrect. 100 mL/hr would deliver over 10 hours.
Plain-language takeaway
Divide total volume by total time: 1,000 mL / 8 hr = 125 mL/hr.
Simple analogy
Think of iv calculations like following a short checklist: identify the clue, confirm the rule, and then make the move that fits this exact scenario.
How to review it before a retake
- Underline the command word and name what the question is asking before rereading the choices.
- Compare the correct answer against the closest distractor and write the exact detail that separates them.
- Retest this objective with a fresh question without looking at the rationale first.
