◉ Two primary functions of the circulatory system.
Answer: deliver oxygen, nutrients, hormones, electrolytes, and other
essentials to the cells, remove carbon dioxide and metabolic waste
from the cells (also helps fight infection)
◉ Arteries.
Answer: Do not stretch very easily, large increase in pressure causes
small increase in diameter

Answer: Stretch easily, small increase in pressure causes large
increase in diameter

Answer: HRxSV
◉ Formula for Arterial pressure.
Answer: PRxCO
,◉ Nephron.
Answer: Basic functional unit of the kidney
◉ Three basic functions of the kidneys.
Answer: Cleansing of ECF and maintenance of ECF volume and
composition, Maintenance of acid-base balance, excretion of
metabolic wastes and foreign substances
◉ Diuretic Beers Criteria.
Answer: Use with caution in 65 years or older due to the potential to
exacerbate SIADH or hyponatremia, monitor sodium concentration
closely

Answer: K wasting diuretic
◉ Hypokalemia can cause.
Answer: can cause fatal dysrhythmia
◉ Hypokalemia value.
Answer: Less than 3.5mEq/L
◉ Furosemide adverse effects.
