1. Substance that releases H+; decreases ph
-Base
-Acid
-Buffer
-Salt - ANSWER 🗸 Acid
2. Which serous membrane would be found in the abdominopelvic cavity?
-Pericardial membrane
-Pleural membrane
-Peritoneal membrane - ANSWER 🗸 Peritoneal
3. When you receive fluid in the hospital, it is often 0.9% saline solution. What
would happen if the nurse used distilled water instead?
-You would become hydrated more quickly and be much healthier.
-There is no way to predict the effects of distilled water on blood cells.
-The distilled water solution would be isotonic to your cells, so nothing
would happen.
-The distilled water solution would be hypertonic to your blood cells, so they
would lose water and crenate.
-The distilled water solution would be hypotonic to your blood cells, so they
would gain water, swell, and possibly burst. - ANSWER 🗸 The distilled
, water solution would be hypotonic to your blood cells, so they would gain
water, swell, and possibly burst.
