Acid-base balance Flashcard Deck - 10 Cards

Flashcard 1: Acid-base disturbances may affect serum K+ levels via altering activity and directionality of the _____ exchanger

Answer: H+-K+

Flashcard 2: In _____ cells, CO2 is combined with H2O via the enzyme carbonic anhydrase, forming H2CO3

Answer: red blood

Extra: Carbonic anhydrase is located within red blood cells, making this reaction much faster than in plasma.

Flashcard 3: What acid-base disturbance is associated with hypokalemia? _____

Answer: Alkalosis

Flashcard 4: The delta cells of the islets of Langerhans compose 10% of the islet and secrete _____

Answer: somatostatin

Flashcard 5: The osmotic diuresis in diabetic ketoacidosis may lead to fatal arrhythmias by causing _____ depletion

Answer: total body K+

Flashcard 6: Ischemia can occur due to _____ (ex. shock)

Answer: hypoperfusion

Flashcard 7: What are the effects of vomiting, diarrhea or hyperventilation on serum potassium levels? _____

Answer: Decreased (hypokalemia)

Extra: Mechanisms for hypokalemia: - **Vomiting & Hyperventilation**: Respiratory or metabolic alkalosis leads to an intracellular shift of K+ (in exchange for H+). - **Diarrhea**: Direct loss of K+ in intestinal secretions (typically associated with a normal anion gap metabolic acidosis).

Flashcard 8: Un-reabsorbed phosphate (15%) serves as a urinary _____ for H+

Answer: buffer

About Acid-base balance Flashcards for USMLE

These Acid-base balance flashcards are designed for USMLE Physiology preparation, using active recall to help you retain high-yield concepts, clinical correlations, and commonly tested facts. Each card prompts you to retrieve information from memory rather than passively reviewing notes, which research shows leads to significantly better exam performance.

The 202 cards in this deck cover the most important topics in Acid-base balance, including key mechanisms, diagnostic criteria, treatment protocols, and clinical pearls that frequently appear in USMLE examinations. Cards are organised by chapter so you can focus on specific areas or work through the entire topic systematically.

For personalised spaced repetition scheduling that adapts to your performance, unlimited flashcards, and detailed progress analytics, download the Oncourse app.

Frequently Asked Questions

Are Acid-base balance flashcards free on Oncourse?

Yes, completely free. You can study all 202 Acid-base balance flashcards on this page at no cost. For spaced repetition scheduling and progress tracking, download the Oncourse app.

How do flashcards help with USMLE preparation?

Flashcards use active recall — instead of passively re-reading notes, you retrieve information from memory. Research shows this builds stronger, longer-lasting memories and is one of the most effective study strategies for medical exams like USMLE.

How many Acid-base balance flashcards are available?

There are currently 202 flashcards for Acid-base balance under Physiology, organised by chapter. New cards are added regularly to cover the latest USMLE syllabus.

Can I study Acid-base balance flashcards by chapter?

Yes. The flashcards are organised by chapter so you can focus on specific areas or work through the entire topic systematically. Scroll down to the "Study by Chapter" section to pick a chapter.

What topics do these Physiology flashcards cover?

The cards cover high-yield concepts, clinical correlations, diagnostic criteria, treatment protocols, and commonly tested facts from Acid-base balance. They mirror the depth and style of USMLE questions.
