Answer: A
Explanation: definition or google
parabolas that open up are always squared to a positive number, for example x^2 and X^4 are parabolas that open up but x^3 is not
Answer:
32 mL
Explanation:
Step 1: Covert pounds to kilograms. This problem's units are already in kg, so no conversion is necessary.
Step 2: Calculate the number of hours an infusion will last by dividing the volume in the bag (1 liter,or 1000 mL) by the rate per hour: 1000 mL/100 mL/h = 10 hours.
Step 3: In case the problem asks for a dose per minute, you will need to multiply the hours by 60 to convert to minutes, but this problem does not ask for it, it asks for ug/kg/hr, so no need to convert here.
Step 4: Now plug into the equation: 4 ug/40 kg/10 hr = 1600 ug.
Step 5: Now convert the ug into mg by dividing by 1000: 1600/1000 = 1.6 mg.
Step 6: Then calculate the quantity of fentanyl to add, by dividing the 1.6 mg by the concentration of the drug (0.05 mg/mL): 1.6 mg/0.05 mg/mL = 32 mL.
Note: to be truly accurate when adding drugs to bags like this, you should discard 32 mL of fluids from the bag prior to adding the 32 mL of fentanyl.
According to the research, the correct option is bronchiole. The small passageway that ends in several alveoli is called bronchiole.
<h3>What is bronchiole?</h3>
They are tiny structures or flexible ducts that end in the alveolar bronchioles, and these, in the alveolar sacs, transporting the air we breathe to the pulmonary alveoli, where hematosis occurs.
These small airways of one millimeter or less, into which the distal bronchial tree is divided, are made up of a single layer of low ciliated or cuboidal cylindrical cells, goblet cells.
Therefore, we can conclude that according to the research, the correct option is bronchiole. The small passageway that ends in several alveoli is called bronchiole.
