What is the appropriate dose of 1:10,000 (0.1 mg/ml) concentration of epinephrine for endotracheal administration to a baby weig
vlada-n [284]
I believe the appropriate dose will be 1.5 mL, 
Epinephrine is used for both allergic reaction and heart attacks, in an effort to increase blood flow through veins and to reduce swelling in airways. When epinephrine is recognized by receptors on smooth muscles, it causes airway-blocking muscle constriction to subside. Other drugs that may be administered by the endotracheal route include atropine sulfate, lidocaine hydrochloride, naloxone hydrochloride, and metaraminol bitartrate.

Muscle fibers are directly surrounded by which thin layer of connective tissue?
wlad13 [49]

Answer:

The correct answer will be- epimysium

Explanation:

Epimysium is the fibrous connective tissue envelope which surrounds the muscle fibers of the muscle as a whole.

The epimysium plays an important role in maintaining the muscle structure as it protects the muscle from the friction caused by the associated bones and the muscles. The epimysium is continuous with other layers called the endomysium, perimysium, tendons and the fascia.

Thus, epimysium is the correct answers.

Semipermeable cell membranes are made of phospholipids that form a bilayer. What major benefit does this arrangement of the memb
Andrej [43]

Answer:

The correct answer would be c. The cell has a greater level of structural support.

Phospholipds are the structural units of a cell membrane. They are consist of two components; hydrphobic lipids and hydrophylic polar heads.

They make a bilayer structure in which polar heads are in contact with water and lipid part are embedded within the layer.

  • Lipid bilayer gives the rigidity or shape to the cell.  
  • It isolates the cell from the sorroundings.
  • It is semi-permiable in nature and thus prevents or control the movement of substances across the membrane.
  • Being liquid in nature, the cytoplasm would have dispersed in the surrounding in absence of cell membrane.

Hence, most appropriate choice would be c. The cell has a greater level of structural support.
