Final answer:
To maintain the client's baseline cardiac output, the pulse rate should increase. Pulse rates of 62 BPM, 68 BPM, 70 BPM, and 64 BPM would help offset the decrease in blood pressure and ensure effective blood circulation.
Step-by-step explanation:
In order to maintain the client's baseline cardiac output (CO), the pulse rate should increase to compensate for the drop in blood pressure. A decrease in blood pressure could signify a decrease in the amount of blood being pumped out of the heart, so increasing the pulse rate would help maintain cardiac output.
Out of the given options, the pulse rates that could help maintain the client's baseline cardiac output are:
These pulse rates would help offset the decrease in blood pressure and ensure that the heart is still effectively pumping blood throughout the body.
