Q- Which one of the following medications may cause metabolic acidosis by reducing the reabsorption of bicarbonate in the kidneys?
A- Acetazolamide
B- Furosemide
C- Hydrochlorothiazide
D- Spironolactone
A- Acetazolamide- It inhibits the enzyme carbonic anhydrase, which is crucial for the reabsorption of bicarbonate (HCO₃⁻) in the proximal tubule of the kidney. By inhibiting this enzyme, acetazolamide leads to increased excretion of bicarbonate in the urine, which reduces the bicarbonate levels in the blood, leading to metabolic acidosis.

Hi Luke, USMLE stands for United States Medical Licensing Examination. It is a test for all medical students and foreign medical doctors to be licensed to work in the USA as physicians. I post questions that are repeated in most of these examinations. Please let me know if you need more information. Thank you for stopping by.
Hmmmmm I got all of the answers wrong, probably because I don’t know what Repeated USMLE is… You will have to excuse my ignorance… If you would like to inform me I would love to know more on what it is 🙂
Hi Tom,
Thank you so much for your kind and thoughtful words. I truly appreciate you taking the time to share this encouragement.
It’s inspiring to hear from someone who works closely with young leaders and is passionate about helping them reach their full potential. Supporting medical students is something I deeply care about, and your message reinforces why this work matters.
Thank you again for your support and positivity.
Warm regards,
Hi,
This is such an informative post and website for medical students.
I am not a medical student but I do work with young leaders as an author, coach, mentor and speaker, and I love learning about new websites that help students to become their best.
Helping young people, especially medical students can only be good for the future of our world.
Keep up the amazing work my friend.
All the best,
Tom
Hi Michael, I appreciate your feedback. Hiding the answer, I got it from experience while in college. I am sure it helps the student to think before getting the correct answer. Thank you again, and have a great day.
I am not from the medical field, but I see the value of this quiz. I love how it allows you to think about the question before opening to the answer and explanation. I took this and got 2 of them right based on personal experience. The STD tripped me up because I had never heard of it before.
I wish I could find a guide like this for Fluid Mechanics!
