When the pregnant Korean woman is being prepped for surgery, Col. Potter asks if any of the doctors have done a Caesarean section, and Hawkeye quips, "I haven't delivered a kid since I drove my nephew over to his grandmother's." However, Hawkeye had delivered a baby aboard a bus in an episode from the previous season.
When the cry of the new baby is heard in the scrub room, Father Mulcahy asks all to pray for the mother, he makes the sign of the cross on himself, then glances to his left to see Klinger with his head bowed. After their brief conversation, Father Mulcahy crosses himself again.
As this is Major Burns' second Purple Heart of record, he would have received a small star in lieu of a second medal.
When Margaret is pinning the Purple Heart onto Frank's scrubs shirt, Loretta Swit's fingernails can be seen to be almost an inch long. No nurse, especially a head nurse, would have fingernails that long.
Hawkeye steals Frank's Purple Heart to give to a baby. However, whether or not a soldier possesses the physical medal, they are officially on record as a recipient and can obtain a replacement. Also, BJ claims "They're staying up nights making Purple Hearts" when comforting Frank, but this was not true. The US military ordered 500,000 of them made in anticipation of the invasion of Japan, which never happened since the atomic bombs were dropped instead. This supply of Purple Hearts has not been used up as of 2015.
BJ saying "They're staying up nights making Purple Hearts" is a jab at the fact that there are plenty to go around and the powers that be supply plenty of war where the medals are given. It's not meant to be a reflection of factual accuracy. While the information given is interesting, it's not a mistake. Additionally, BJ tells him he can get another one, which is entirely true.

When Nurse Cratty first arrives with the orphans, Hawkeye introduces BJ and tells her that Trapper went home. Next, she speaks with Colonel Potter, who arrived at the 4077 after Trapper left and BJ arrived, but they act like they already know each other. While it's possible she might have met Potter before but not BJ, she likely would at least know that Trapper was gone. It's not necessarily an error, but it is somewhat strange.
As stated, it's not necessarily an error, which it isn't, as Nurse Cratty could have met Col. Potter before his assignment to 4077 or at some point after, but not BJ and Trapper's going home didn't come up. Even more remotely, she may have met him prior to the Korean war. Any of these possibilities make their behavior , while not explained, perfectly normal.

When "Slicky Boy" ("Jasper") pulls the shower handle to release the shower water on Maj. Burns, B.J. can be seen through the shower-tent window in the background, waiting for his cue to open the door and stop Maj. Burns from continuing to chase after the boy.
B.J. mentions that his wife is 5'1". However, Catherine Bergstrom, the actress who portrayed Peg Hunnicutt in several episodes, is clearly taller than 5'1", as can be seen in her dance with the 6'3" B.J. during the Season 8 episode, ''Dreams."
In his telling the fable of Androcles and the lion, BJ provides too much detail (about Androcles religion) for young children to understand, especially children who understand just a little bit of English.
