✓ Correct: Verify patient identity using two patient identifiers

Verifying patient identity with two identifiers (name plus DOB or MRN) is the most critical step in medication safety. Wrong-patient errors are among the most serious preventable medication errors. This step must occur before every medication administration, without exception.

✓ Correct: Potassium level 2.9 mEq/L

Furosemide depletes potassium. A potassium of 2.9 mEq/L (hypokalaemia) combined with furosemide creates dangerous cardiac arrhythmia risk. Report and correct before administration. Other values are within acceptable ranges.

✓ Correct: Ask a more experienced nurse to supervise and guide

Recognising the limits of your own competence and seeking supervision is the hallmark of safe, professional nursing practice. A new nurse who is unsure must seek guidance rather than attempt the procedure unsupervised. This is patient safety at its foundation.
