How to interview a patient with excessive thirst and urination
Other platforms explain it with text and video. In Making Synapses you practice it on the patient.
Thirst and frequent urination together suggest high blood sugar. Check the glucose and look for ketoacidosis.
Step by step
Check glucose
Bedside glucose early. [1]
Introduce yourself and get consent
Ask about the timeline. [2]
Symptoms
How much they drink and pee, night urination, since when. [3]
Weight and energy
Weight loss and fatigue suggest high sugar. [4]
Ketoacidosis signs
Vomiting, belly pain, fast breathing, fruity breath, confusion: urgent. [4]
Other causes
Lithium, diuretics, high calcium, pregnancy. [4]
Summarize and plan
Explain tests and treatment. [2]
Common errors
- No glucose check.
- Missing ketoacidosis.
- Not asking about lithium.
Practice it in Making Synapses
In Making Synapses you do this on the patient, not on paper: every step goes on the checklist with a score, and in Teach mode Blocky tells you what comes next.
