If we take the poster with good faith we can assume he genuinely thought the doctor might know some useful ways he could be of help that neither he nor his wife knew. Even if there wasn't (which seems unlikely to me) I feel like good bedside manner should extend to a patient's loved ones when possible. Simply addressing him politely to say "Just be available and help as you can." would have be a far kinder way to blow off an anxious person.

A good example of something a doctor could tell the other half is like “if she can’t get out of bed and you take her blood pressure and it’s X then call me but if it’s Y then call 911”. Those are important things a partner needs to know during a pregnancy.

I did not got instructions for "if I can't get out of bed" and I was the pregnant one. Nor the relationships style advice about availability and interpersonal help.

Both kind of suggest there is not much to tell, like they are doctor going out of way to give advice about stuff they normally don't talk about, just to have something to say.
