Interactive tools for the topics that are hardest to memorise
Some nursing topics are not lists — they are systems, and a chart cannot teach a system. These tools let you move one thing and watch what else moves. They are free, they need no account, and they run entirely in your browser.
Simulator
Fluid & Electrolyte Simulator
Move sodium, potassium, calcium, magnesium, phosphate, pH or volume and the rest of the patient answers — labs, vital signs, ECG and assessment findings. Sixteen imbalances and four relationships to load, a firing meter that derives every hypo- and hyper- symptom, and an IV pole where every bag runs — the wrong ones too.
More free study material
The Learning Center covers every topic in these tools in full, and the game modes drill the pairs students confuse most. Both are free to start.
