Do pt need to void before being d/c post MI?

[MrRockerSN]

Ok this is sort of my last resort. I've checked my med-surg book several times and I can't find this specific bit of information. When a pt has had an MI, before s/he is discharged, do they have to successfully void 20ml? I think so because not voiding might be a sign of CHF, and voiding is something all patients should be doing in general.

Any input will be appreciated!

Consider how long an average hospitalization for an acute MI (or even a rule-out MI) is and what is considered the bare minimum for adequate hourly urine output and put the two together to find your answer.

The bare minimum of output that you want per hour is 30 mL. If you are not getting 30 mL per hour, something is wrong; Unless the patient is not taking any fluids in because of renal failure or some other disease or NPO, fluid restriction etc.

Definitely what I thought too. But I wasn't sure if there was a specific protocol for post MI patients that I wasn't finding. I definitely expect the pt to be voiding more than 20ml/hr.

Yeah, you definitely want your patients to urinate. I'd be careful with the 20 mL/hour though. I thought that as well and I've missed quite a few ATI NCLEX style questions because of that. My professor said go with 30 mL/hour but I'm not sure if that's like the universal amount you want per hour.
