D. To monitor a flu epidemic at a school in Florida
Answer:
The correct answer is D.
Explanation:
The normal value range of pH is 7,35-7,45.
If the pH es <u>higher than 7,45</u> we say it is alkalosis and if the pH es <u>lower than 7,35</u> we say it is acidosis. That being said, we can now rule out option B and C.
Then we have to define <u>respiratory acidosis:</u> it is a decrease of pH because of a high value of PaCO2 (in this case as a result of hypoventilation). The normal range of PaCO2 is 35-45 mmHg.
So if we take all this in consideration, the only option with a low pH and a high paCO2 is option D.
Answer:
d. increases their energy density and decreases nutrient density.
Correct; adding sugar to food increases energy density and decreases nutrient density.
Answer:
Ascertain that the needle is not in a blood vessel
Explanation:
In subcutaneous administration, a small amount of liquid medicine is injected into the subcutaneous tissue below the patient's skin. This type of injection is indicated for the administration of anticoagulants, hypoglycemic agents and vaccines (anti-rabies and anti-measles). The drug is slowly absorbed into the nearby capillaries, giving prolonged effect of the drug. Intramuscular injections deposit the medication deep into the muscle tissue, which is highly vascularized and can absorb rapidly. This route of administration provides rapid systemic action and absorption of relatively large doses.
Regardless of whether the injection is subcutaneous or intramuscular, one should carefully pull the plunger to make sure that the needle is not in a blood vessel and does not cause bleeding.
