Final answer:
The 2nd stage of labor lasts 2-3 hours for a primigravida and 1-2 hours for a multigravida, reflecting the shorter duration of labor in subsequent pregnancies due to the body's previous experience with childbirth.
Step-by-step explanation:
The 2nd stage of labor and delivery lasts for different durations for primigravida and multigravida. Primigravida refers to a person who is giving birth for the first time, while multigravida refers to someone who has been pregnant previously. For a primigravida, the 2nd stage, which is when the baby is expelled from the uterus, typically lasts 2-3 hours. On the other hand, for a multigravida, this stage tends to be shorter due to their body's previous experience with childbirth, generally lasting 1-2 hours.
Therefore, the correct answer to the question "The 2nd stage of labor and delivery lasts ______ hours for a primigravida and ______ hours for a multigravida" is: b) 2-3 hours for primigravida, 1-2 hours for multigravida.
