I've come to this unfortunate situation. The person might not be pregnant. She's 6 weeks postpartum, but the serum pregnancy test is (+). I re-ordered a new one, but made it a quantitave test, which had a level of 46, which indicates 4-6 (edit 1-4) weeks gestation. That definitively tells me (edit-nothing)anything because if she got pregnant again, it fits in the right time period. It does though at least give me a reference level, so when I order the test again in 2 days, if the HCG level is about double--then she really is pregnant. If not then its a false (+), retained placental products or just a false (+) that can happen post partum (supposedly for a few weeks). In the meantime, she's grossly psychotic-paranoid, & often starting fights with other patients. She's on Haldol 20mg TID, and 10mg QIDPRN for psychosis--she pretty much gets all her PRNs. We have seen some improvement with the haldol but not much. OK if she's not pregnant by as indicated by the next lab test--I'm in a good situation--I can give her pretty much every med I want. IF not, I'm screwed--an actively psychotic patient who's already pretty much near her Haldol maximum and unless there's other meds I can give, won't expect much more improvement. Anyone know of any data showing that other antipsychotics are safe with a good body of data?
