1. Why is it important that a person's arm is at heart level when taking blood pressure measurements?
2. An astronaut's pulse rate on the day before launch is 65 beats per minute. After 3 weeks in orbit, the astronaut returns to Earth. Would you expect the astronaut's pulse rate to have changed? Explain please!

If the person's arm is a heart level it means that the blood will not have to travel upwards or downwards to the spot where you take your pulse. Have you ever heard of people elevating a bleeding leg so it doesn't bleed as much? That is to use gravity to ones advantage, as the blood will have to move harder to strain upwards. That is why you should hold your heart arm level
As for the astronaut, I would expect the pulse rate to go down. Without gravity, your heart does not have to struggle as hard to pump the blood all over your body, therefore requiring few beats per minute to push the blood through them. Hope I helped!!!
