It will bleed... Profusely.
Once you get the bleeding to stop, she will stand up and shake, breaking open the wound, and flinging blood all over your wife's kitchen.
When you reapply pressure for 30 more minutes and stop the bleeding, she will shake again, breaking the clot again, this time in a different area of the house.
Applying superglue is a complete waste of time, and when you think the glue is all dried, she'll shake, and end up with a bunch of glue on the top of her head and under her chin.

Your wife will not be impressed with this comedy of errors.
