Answered step-by-step
Asked by maharjanrojee11

Mr Ranato B is a 35-year-old professional who takes a trip to Denver, Colorado
and upon arriving finds it difficult to breathe. He presents at a local GP clinic to
be assessed and the GP has asked the practice nurse to assess Ranato’s physical
presentation. Ranato’s chest wall was observed and palpated during normal quiet
breathing.
a. From the examination Ranato’s respiratory rate is recorded as 30 breaths per min. Would
you report back to the GP that Ranato was breathing at a normal rate? Include in your
answer what a normal breathing rate should be. 
b. Knowing that Denver is at “altitude” with an atmospheric pressure of 632 mmHg, calculate
the partial pressure of oxygen (PO2) 
c. With the PO2 in mind, explain why Ranato may have a respiratory rate of 30 breaths per
min 
d. When Renato was examined, he was lying flat on his back. Explain whether there would
be differences in his ventilation and perfusion if he sat upright. Give reasoning to support
your answer. 
e. Given the respiratory rate observed, the nurse decides to measure Ranato’s oxygen
saturation which were between 95% and 100%. Describe why these levels are relatively
normal given the respiratory distress Renato appears to be in.
