Case 18: The Lithium Thirst
Self-study case · 8 decision primers
Assess perfusion, then compare plasma and urine concentration. Connect water loss, calcium and the lithium/diuretic exposure timeline.
Bring the lecture to the bedside · self-study
Start with the visual framework, learn the concept before each question, then commit to your answer and reveal the explanation. Revisit urgent threats as new findings arrive. Use the interpretation and treatment diagrams to explain the patient’s course.
The 13 assigned self-study cases and two additional cases follow the classroom sequence. These links also appear in each day’s teaching hub.

Case 19: The Post-Op Problem
Self-study case · 7 decision primers
Identify the sodium swim lane, assess neurologic urgency and review every fluid input. Revisit the plan when a water diuresis appears.
Case 20: The Stone Former with Low Potassium
Self-study case · 6 decision primers
Define the acid–base disorder, interpret the urine’s response and connect potassium, citrate, urine pH and stone composition.

Case 16: The Late Referral
Additional case · 8 decision primers
Separate an urgent dialysis indication from long-term preparation. Combine filtration, albuminuria, trajectory and risk with the patient’s goals.
Case 21: The Executive Physical
Self-study case · 8 decision primers
Verify pressure and chronicity before labeling disease. Use medication and electrolyte clues to guide secondary-cause testing and a coordinated prevention plan.
Case 22: The Medication Minefield
Self-study case · 8 decision primers
Review each medicine by indication, clearance, dose and exposure. Look for accumulated toxicity, interacting drugs and procedure-related risks.

Case 23: The Resistant Heart Failure
Self-study case · 7 decision primers
Follow the edema circulation pathway before accepting a heart-failure label. Quantify protein, assess the glomerular syndrome and watch for complications.
Case 24: The Two Swollen Cousins
Self-study case · 7 decision primers
Use pediatric thresholds for the child, then compare the adult’s cause-specific pathway. A shared nephrotic phenotype does not imply the same lesion or treatment.
Case 25: The Puffy Second-Grader
Self-study case · 7 decision primers
Recognize the nephritic pattern using pediatric BP and creatinine context. Interpret infection/complement findings and follow the recovery trajectory.
Case 26: The Sports Physical
Self-study case · 7 decision primers
Repeat and quantify the urine findings, keeping protein and blood as separate questions. Family history and urologic risk can point toward different investigations.

Case 27: The Day-Six Creatinine
Self-study case · 8 decision primers
Map exposures against the creatinine and sediment timeline. Allow overlapping tubular and interstitial injury, and reassess dosing as kidney function changes.
Case 28: The Lymphoma Admission
Self-study case · 8 decision primers
Recognize tumor lysis and treat cardiac, calcium and volume threats in parallel. Review superimposed crystal injury and arrange definitive removal when needed.
Case 29: The Cirrhotic's Creatinine
Self-study case · 6 decision primers
Separate total-body fluid excess from effective arterial filling. Investigate infection, depletion, drugs and obstruction before assigning the HRS phenotype.
Case 30: The Prostate Problem
Self-study case · 7 decision primers
Identify impaired emptying, relieve significant obstruction and anticipate the change from retention to post-obstructive water and electrolyte losses.
Day 5 · self-study and additional cases

Case 17: The Octogenarian's Numbers
Additional case · 8 decision primers
Read the laboratory numbers through frailty, muscle mass, medicines and patient preferences. Treat acute toxicity before deciding what chronic kidney care should look like.
Evidence and further reading
Each short lesson links to the relevant lecture and the original question’s evidence. Clinical updates were checked against the current CKD, tumor-lysis and cirrhosis guidance; the case questions remain in their original sequence.
