The physician orders 1,000 micrograms \( (\mathrm{mcg}) \) of a drug PO. The pharmacy sends the drug labeled 1 milligram \( (\mathrm{mg}) \) per tablet. The nurse is correct to: contact the pharmacy to verify the dose. administer 1 tablet. administer \( 1 / 2 \) tablet. not administer the drug.

Did you know that 1 milligram (mg) equals 1,000 micrograms (mcg)? This means that if a physician orders 1,000 mcg, that’s precisely equivalent to 1 mg. So, when the pharmacy sends a tablet labeled as 1 mg, it is the exact dose prescribed! In real-world medical scenarios, especially in pediatrics or critical care, it’s not uncommon to encounter confusion around dosage units. Always double-check if you're in doubt, but in this case, the correct action would be to administer 1 tablet! Making sure to stay aware of these conversions is crucial for patient safety.
