Ideal weight [61.4] kg, adjusted [92.0] kg and actual [138] kg are matched to five agents, each with a cited reason, in this composite NU648 dosing weight worksheet. Searches like "nu 648 unit 2 assignment example", "nu648 unit 2 sample" and "nu648 unit 2 example" land here.
What a finished NU648 Unit 2 dosing weight worksheet looks like
A calculation block and a five-row table on two pages. The block computes ideal body weight by the Devine formula (1974), adjusted body weight with the [0.4] correction factor, and body mass index, showing every step with units. Columns cover agent, weight used, why that weight, source, and the bracketed dose that results. Daptomycin takes actual weight, as its label directs, with creatine kinase monitoring noted because exposure rises with dose. Tobramycin takes adjusted weight, since aminoglycosides distribute poorly into fat but not negligibly. Enoxaparin prophylaxis follows a tiered approach for a body mass index above [40], labeled as institutional practice. Weight-based insulin starting estimates use actual weight. Metronidazole appears as a fixed dose that no weight changes. A footnote states which weight the clearance estimate used and why.
How a NU648 Unit 2 example is structured
Calculation precedes assignment, so all three weights exist before any drug is matched to one, and the worksheet's central act, choosing, stays visible rather than buried in a dose. Every row puts one question in one place: which property of this drug decides the weight. The answer is almost always distribution. Water-soluble agents such as aminoglycosides spread into lean tissue and extracellular fluid, so adjusted weight corrects for their partial reach into fat; drugs dosed by label on total weight, like daptomycin, are taken at the label's word with a monitoring caveat. Where evidence is thin, as with prophylactic enoxaparin in severe obesity, the worksheet says so and names the convention it follows. The fixed-dose row is deliberate, showing that weight is not always the variable. The clearance estimate's weight is recorded last, since it shifts renal dosing too.
Three weights, computed once
Ideal, adjusted and actual weight are worked out in a single block with the Devine formula and the [0.4] factor. Results are rounded at the end, not along the way, so each line of arithmetic can be verified.
Distribution decides the weight
Each row names the property that drives the choice: water solubility, lipid solubility or a label instruction. Tying the weight to pharmacology rather than habit is what separates this worksheet from a lookup table.
When the label settles it
Daptomycin's label specifies total body weight, so the worksheet uses [138] kg and schedules weekly creatine kinase checks, citing reports that muscle toxicity climbs with higher exposure.
Where evidence runs thin
Prophylactic enoxaparin above a body mass index of [40] has no settled dose. The worksheet cites observational data, names the tiered approach as local practice, and pairs it with an anti-Xa level after the [third] dose as a check.
The row weight does not touch
Metronidazole is dosed the same for any adult, and the worksheet includes it so that a reader sees fixed-dose agents were considered rather than forgotten.
Where marks go in NU648 Unit 2
A weight chosen without a reason is what markers catch first, and a worksheet that computes three weights and then applies actual weight to everything shows the calculation without the judgment. Aminoglycosides dosed on actual weight in severe obesity are the most frequently marked error, since the resulting peaks can far exceed target. The reverse mistake, ideal weight for a drug whose label specifies total weight, draws a similar comment. Arithmetic shown without units, or rounded early, makes the ideal-weight figure hard to verify. Presenting an institutional convention as a universal rule, especially for enoxaparin in obesity, loses credit for overstating the evidence. Leaving unstated which weight fed the clearance estimate is a smaller omission, though it has knock-on effects for any renally dosed row.

NU648 Unit 2 questions, answered
Is lean body weight ever the right choice?
For some drugs, yes. Lean body weight, estimated with equations such as Janmahasatian's, is used by some references for certain anesthetic and sedative agents. The sample includes it only when the prompt's drug list calls for it, and then cites the reference that recommends lean weight for that agent specifically.
What if references disagree on which weight to use?
They sometimes do, particularly for older drugs studied before obesity was common. The sample names both positions, picks one for a stated reason, and cites both sources. A reasoned choice between documented options earns more credit than pretending the references agree, and it shows the references were actually consulted.
Should the worksheet include the final doses?
Only as bracketed placeholders, which is how the sample presents them. The graded skill is matching weight to drug with a reason; the resulting number depends on current references, pharmacist verification and the prescriber. Showing where a dose would come from, without offering one for an actual patient, keeps the worksheet within coursework.
