Translated from the German original, which is authoritative. The exam itself is in German.

Material

• Blood glucose meter (control measurement carried out per local hospital standard), test strips (check the expiry date)
• Single-use safety lancet, swab, disposable gloves
• Sharps container, documentation sheet

Typical mistakes in the exam

• Measuring first in a person with impaired consciousness instead of acting immediately
• Measuring while the disinfectant is still wet
• Squeezing the finger hard
• Documenting the reading but not evaluating it

What examiners ask afterwards

• From what value do you speak of hypoglycaemia, and what do you do?
• What do you do if the person can no longer swallow safely?
• How do you explain self-monitoring to a person newly diagnosed with diabetes?
