Weight converted, range calculated, order compared, then a volume: five composite pediatric problems worked in that order for NU225 Unit 4, one overdose and one underdose flagged. Searches like "nu 225 unit 4 assignment example", "nu225 unit 4 sample" and "nu225 unit 4 example" land here.
What a finished NU225 Unit 4 medication dosage worksheet looks like
Each problem takes half a page and the same five lines: weight in kilograms, safe range per day and per dose, the ordered amount compared against it, a verdict, and a volume only if the verdict allows one. Drugs are lettered, [Drug A] through [Drug E], and each range is printed in the problem as an exercise value. Problem one converts 19 pounds 6 ounces to 8.8 kilograms, sets a range of 352 to 440 mg a day, or 176 to 220 mg per dose every twelve hours, and finds the ordered 200 mg inside it, giving 4 mL of a 250 mg per 5 mL suspension. Problem three, for a twenty-kilogram six-year-old, totals 1,200 mg a day against a 1,000 mg maximum and stops. Problem five finds a dose too small to reach its range.
How a NU225 Unit 4 example is structured
The sequence follows the kinds of error a pediatric worksheet exists to catch. Problems one and two pass their checks and establish the method. Problem three carries the trap: 300 mg every six hours sits inside the per-dose range worked out for dosing every eight hours, but four doses a day come to 1,200 mg, or 60 mg/kg, above the 50 mg/kg ceiling. Problem four introduces a cap, 10 mg/kg per dose but never more than 400 mg, so the thirteen-year-old's 550 mg calculation is capped and the 400 mg order is judged against the cap. Problem five is the underdose, 180 mg a day for a 12.4-kilogram toddler, or 14.5 mg/kg against a range that begins at 30. A rounding key sits above problem one: weights to tenths of a kilogram, oral volumes to tenths of a milliliter.
Kilograms before anything else
Pounds and ounces are converted a single time and rounded to a tenth, and that one figure carries through the whole problem instead of being recalculated at each step.
Frequency checked with the dose
Problem three looks safe dose by dose and fails only when the ordered frequency is multiplied out across a day. The worksheet shows the daily total on every problem for that reason.
A ceiling that overrides the weight
For the adolescent, the weight-based figure exceeds the stated maximum, and the worksheet shows the cap taking precedence, a rule pediatric rubrics often test with older, heavier children.
Too little is also a finding
The underdose in problem five is flagged with the same seriousness as the overdose, since a dose below range can fail to treat, and no volume is prepared for either one.
Exercise values, not references
Drugs are lettered and every range was invented for the worksheet. The page states that its numbers teach method only and apply to no real child and no real order.
Where marks go in NU225 Unit 4
Scoring on a pediatric dosage worksheet commonly runs problem by problem, with separate credit for the conversion, the range, the comparison and the volume. A correct volume prepared for an order outside its range usually earns nothing for that problem, which is why the verdict line precedes any volume. Conversion slips are expensive as well, especially ounces handled as decimals of a pound, or a per-day range applied as though it governed a single dose. Caps on the maximum dose are frequently missed with adolescents, whose weight pushes the calculation past them. Some students treat an underdose as safe because it is small, and graders mark that as a reasoning error. Units left off answers, rounding applied unevenly and verdicts given without a reason cost smaller amounts across the set.

NU225 Unit 4 questions, answered
Should the weight be rounded before or after calculating the range?
Follow the rule your course sets, and apply it the same way on every problem. The sample rounds weight to a tenth of a kilogram first and uses that figure throughout, which is a common convention. Rounding differently from one problem to the next produces small inconsistencies that graders notice, even when each answer is close.
What should the worksheet say when an order falls outside the range?
That it would be questioned with the prescriber before preparation, and why, using the numbers. The verdict line states the ordered amount, the range and the gap, then stops without calculating a volume. Most rubrics credit that stop as the correct answer, because preparing an unsafe dose accurately is still preparing an unsafe dose.
Can these answers be used to check a real child's dose?
No. The drugs are lettered, the ranges are invented and the children are composites, so none of the page applies outside the exercise. In practice, a child's dose is checked against the prescriber's order, current drug references, pharmacy review and facility policy, often with an independent double check for high-alert drugs. The worksheet demonstrates method and layout only.
