Default renal phys

A 25 yo man comes to the ED complaining of several days of abdominal pain and multiple loose stools that began shortly after a recent camping trip. He appears lethargic and PE shows decreased skin turgor, HR of 120/min, and RR 28/min. Oxygen saturdation is 99% on room air (normal)
Which of hte following best characterizes this pt's acid-base status?
a. Metabolic alkalosis
b. NAG metabolic acidosis
c. respiratory acidosis
d. respiratory alkalosis
e. NAB metabolic acidosis

I got this one from RX, but still confused with their explanation. My first post so be easy on me

lower GI is more alkaline as it has greater amount of bicarbonate and others so when you have diarrhea you are losing the basic fluid,, which is loss of ECF.. hence you develop an acidosis.

Respiratory compensation comes into play and causes hyperventilation to rid the body of CO2 (acid component of the equation: CO2 -> <- HCO3- + H+)

hence increased RR in the patient..

dehydration in diarrhea can also cause contraction alkalosis but thats not in the option..

thank you reading rx explanation didn't help, but your explanation does! I also found out that the kidney will reabsorb Cl- anion when bicarb is low, that's how they balanced out!
