Often times, when "med math" is discussed, someone will pipe in with something along the lines of "well, the pharmacy actually does that... we just verify it," or "we use 'smart pumps.'"
Here's a real-world example from yesterday...
Ambulance delivers a patient who'd taken a header from the third floor balcony... obvious severe head trauma...
The patient gets intubated and needs to go to the scanner STAT. He's just starting to brady down a bit, "Bolus him 75 grams of mannitol and get him to the scanner now."
Our pyxis holds mannitol available as 20% mannitol in 250 mL of D5W.
What do I do?

Think about and I'll post the answer in a bit...
