Final answer:
The fetal monitor paper is used to record the fetal heart rate and contractions during labor. Each block on the monitor paper represents a specific amount of time. To determine the number of blocks per minute for fetal tracings at 3cm/min, divide the speed of the tracings by the speed of the paper.
Step-by-step explanation:
The fetal monitor paper, also known as the fetal monitoring strip, is used to record the fetal heart rate and contractions during labor. The paper consists of a grid with blocks that represent a certain amount of time. In this case, the question states that the fetal tracings are at 3cm/min. Each block on the monitor paper represents a specific amount of time, which is determined by the speed of the paper. To determine how many blocks per minute are used, we need to know the speed of the paper in cm/min. Once we have that information, we can divide the speed of the tracings (3cm/min) by the speed of the paper to find the number of blocks per minute.
