In regards to a patient who is hypoxic, what is the minimum number we look for in a patient's oxygen saturation?
a) 85%
b) 88%
c) 91%
d) 94%

 the correct answer is c) 91%

Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent.

As stated above, a reading of 94 to 99 percent or higher indicates normal oxygen saturation, and anything below 90 percent is considered to be low blood oxygen, also known as hypoxemia.

Explanation:

Hypoxemia occurs when oxygen levels in the blood become so low that tissues and organs in the body don't get the oxygen they need. This happens because COPD damages the air sacs, which means the lungs cannot transfer the available oxygen to the bloodstream.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
