Built on a composite high-output ileostomy, NU142's Unit 2 case study analysis interprets the acid-base result, links a doubled creatinine to volume loss and orders the replacement correctly. Searches like "nu 142 unit 2 assignment example", "nu142 unit 2 sample" and "nu142 unit 2 example" land here.
What a finished NU142 Unit 2 case study analysis looks like
The analysis begins with the numbers the case supplies and groups them before interpreting any. Output from the stoma measured 2.1 liters over 24 hours against 1.4 liters taken by mouth. Sodium sits at 131, potassium at 3.1, magnesium at 1.4 and bicarbonate at 18, while creatinine has risen from 0.9 to 1.9 with a BUN of 38. The arterial gas shows a pH of 7.31 and a PaCO2 of 32. The paper reads that as metabolic acidosis with partial respiratory compensation, explained by bicarbonate lost in small-bowel fluid. The creatinine rise is called prerenal, supported by a BUN-to-creatinine ratio near twenty and the orthostatic change. Replacement follows in order: isotonic fluid, magnesium corrected so potassium will hold, then potassium once urine output is confirmed.
How a NU142 Unit 2 example is structured
Most sections supply questions with the case, and the sample answers them under numbered headings, but it adds one element the questions rarely ask for: a data table placed ahead of the first answer. Each row gives a value, its normal range and a one-word direction, so every later claim can point back to a row. Acid-base interpretation follows as a short worked sequence: pH, then the respiratory value, then bicarbonate, then compensation. A paragraph on kidney function separates volume loss from kidney injury. Next comes the priority statement, deficient fluid volume, defended against the potassium problem that competes with it. Interventions appear in their real sequence, each with a rationale and the value that would show it worked. Discharge teaching is limited to what this stoma changes about drinking and monitoring.

Three losses in one bag
Small-bowel effluent carries water, sodium and bicarbonate together, with potassium and magnesium besides. The analysis traces every abnormal value in the case back to the stoma, so the labs read as one mechanism instead of five separate problems.
Compensation read from the PaCO2
A pH of 7.31 with bicarbonate at 18 names the primary disturbance. The paper then points to the PaCO2 of 32 as the lungs blowing off acid, and states that compensation is partial because the pH has not returned to range.
Magnesium ahead of potassium
Low magnesium lets the kidney keep wasting potassium, so replacement that ignores magnesium tends to fail. The sample sequences the magnesium first and explains why the potassium value might barely move otherwise.
Urine output before the potassium bag
Potassium given to a patient whose kidneys are not clearing it can climb fast. The plan confirms urine output against a stated minimum before the first potassium infusion and notes that intravenous potassium is never pushed.
Plain water as the wrong advice
Large amounts of plain water can increase stoma output and dilute sodium further. The teaching section names an oral rehydration solution instead, at whatever volume the provider sets, which is the detail graders look for in this case.
Where marks go in NU142 Unit 2
Values reported without interpretation cost the most here: a table of labs followed by a care plan that never says what the numbers mean together. Reading the gas as respiratory acidosis, or as uncompensated, is the content error graders mark most often, and everything built on it inherits the mistake. Treating the creatinine rise as intrinsic kidney disease, with no mention of volume, misses the reversible cause the case was built around. Potassium replacement listed without a check of urine output, or without magnesium, draws safety deductions in most sections. A plan recommending more plain water loses points on teaching. Interventions set out in no particular order, goals with no measurable value attached, and outside sources older than the current course text account for the remaining losses on this assignment.

Fluid cases vary: vomiting, diarrhea, a stoma, a diuretic, a burn. Whichever loss drives the Unit 2 case posted in your section, pass it on, numbered questions and rubric included. The analysis then works from that data and answers each question in turn, in the order asked. As a first custom sample it is free, and delivery typically takes 24-48h.
NU142 Unit 2 questions, answered
How much acid-base working should the analysis show?
Enough for a grader to follow the steps: pH first, then which value explains it, then whether the other system is compensating and how far. A single sentence naming the disorder, with no working, rarely earns the full interpretation marks. Most sections do not require a formal method such as a tic-tac-toe grid, though any method the course teaches can be shown.
Does every abnormal lab need its own nursing diagnosis?
No. Grouping labs under the problem they explain is usually stronger than writing five diagnoses for five values. In this case the sodium, potassium, bicarbonate and creatinine all sit under the losses from the stoma. Separate problems belong only where a finding needs its own intervention, such as fall risk from orthostatic dizziness, which gets its own line in the sample.
What if my case involves vomiting instead of diarrhea?
Then the acid-base picture usually flips. Vomiting removes stomach acid, which tends to produce metabolic alkalosis with low chloride, whereas intestinal losses usually produce acidosis. The shape of the analysis stays the same: data table, interpretation, kidney function, ranked priority, sequenced replacement. What changes is the mechanism paragraph and which values the monitoring plan follows.
