Assessment Task 2 B Bertha, the story continues: Bertha is a 75 years old First Nations elder who is recovering from a fractured pelvis. She has been working with the physiotherapists to ensure that she does not lose strength before being discharged from hospital. Today she had a session with the physiotherapists. Before taking Bertha to the gym, a set of vital signs were collected before she gets out of bed. Results are: RR 14 bpm, SpO2 98%, BP 130/70 mmHg (Mean arterial pressure 90 mmHg), HR 74 bpm. The nurse tells the physios that Bertha is well and has no cardiovascular or respiratory diseases. The physiotherapists took her to the gym, where she undertook some exercises under their direction. Collect cues: After the first round of exercises, they check her vital signs again. Her respiratory rate is now 20 bpm, her SpO2 is 100% on room air, BP is 140/80 mmHg (Mean arterial pressure 100 mmHg), and HR is 90 bpm. She is observed to be breathing deeply and using accessory muscles. 1. Explain the physiological mechanisms which have caused Bertha's respiratory rate to change during exercise (suggested 350 words) 2. Would you expect Bertha's arterial pH levels to change during her exercise? Explain why or why not? (suggested 150 words)
