Q

Why cardiogenic shock cannot be fixed with volume administrtion or removal?

Q

Explain why pulses in LE may be diminished during a ruptured AAA.

A

Blood is going to flow the path of least resistance. If the rupture is on the R side, it’ll flow down LLE and vice versa.

Q

Why do we give IV fluid in a patient in shock?

A

Maintain adequate perfusion

55
Q

Does IV fluid increase the blood’s ability to carry oxygen?

A

No, increased volume of fluid does not equal more blood as you need Hgb to transport RBC.

What are baroreceptors?

A

Nerve cells that sense pressure changes located in the carotid and aorta.

61
Q

Isotonic

A

Equal concentration of sodium inside and outside cells.

62
Q

Hypotonic

A

Concentration of sodium inside cell is greater than outside the cell causing water to through the cell membrane causing swelling and possible lysis.

63
Q

Hypertonic

A

Concentration of sodium outside cell is < than inside causing water to leave the cell shrinking the cell. Called plasmolysis.

64
Q

Formula for calculating IV flow rate in drops/minute.
