Question
Part A

though you are thirsty, you haver’t bothered to buy yourself a drink, Other than a litte soreness of the skin and tissue around your median cubital vein, you feel fine.
most likely affected your cardiac output, heart rate, and stroke volume?
no change in cardiac output, increabed heart rate, decreased stroke volume
no change in cardiac output, decreased heart rate, incteased stroke volume
decrease in cardiac output, decreased heart rate, decreased stroke volume
increase in cardiac output, increased heart rate, increased stroke volume

Answer
When you donate 500 mL of blood, your heart rate increases while stroke volume decreases, but cardiac output remains the same.

Beyond the Answer
After donating blood, your body works hard to compensate for the lost volume. While you might feel fine, your cardiac output is likely to undergo temporary changes. Your body instinctively increases your heart rate to maintain adequate blood flow to vital organs, compensating for the decrease in stroke volume (the amount of blood pumped with each heartbeat) caused by the blood donation. So in this scenario, you’d expect an increase in heart rate and decreased stroke volume without a significant change in overall cardiac output, as the body works to stabilize itself.
When donating blood, staying hydrated is crucial! It’s common for donors to overlook their fluid intake afterward, leading to mild dehydration, dizziness, or fatigue. To enhance your recovery after a donation, consider drinking water or electrolyte drinks and avoiding strenuous activities. This helps replenish your blood volume and supports your body’s recovery process, ensuring you’re back to your vibrant self in no time!
