When uranium emits an alpha particle, it emits an equal number of protons and neutrons. At this point it becomes a simple math problem. If the original nucleus is 238U, then the nucleus has 92 protons and 146 neutrons, giving it an n/p ratio of 146/92 or 1.59. After it emits an alpha particle, the new nucleus is 234Th which has 90 protons and 144 neutrons. For this nucleus the n/p ratio is 144/90 or 1.6, a slight increase.
