True or false: it’s generally more likely to be necessary to place an arterial line for non-distributive shocks (cardiogenic, obstructive, hemorrhagic) than distributive shock, and if done, a central vessel is more likely to be helpful.

Feel like good waveform + pocus guided resus/spot checks are generally helpful and sufficient way more often than not. I've tried hunting for a better central pressure & rarely find it.
Perfect is the enemy of good enough
a difference of 3.5 mmhg in map might be clinically meaningful with respect to vasopressor dose, or might be not. for me, it's the latter. adequate pulseform, good signal on radial - do not change.
