Abstract: We show that every countably compact space which is monotonically normal, almost 2-fully normal, radial $T_2$, or $T_3$ with countable spread is absolutely countably compact. For the first two mentioned properties, we prove more general results not requiring countable compactness. We also prove that every monotonically normal, orthocompact space is finitely fully normal.
