CCRN Sepsis and MODS 4

Question 1

A nurse should recognize that warm, flushed skin with bounding pulses in early septic shock reflects:

Accepted Answer

Vasodilation and high cardiac output (hyperdynamic phase)

Answer

Early 'warm shock' features vasodilation and a high-output hyperdynamic state.

Question 2

Which hemodynamic profile is classic for septic shock?

Accepted Answer

Low SVR, high cardiac output, low CVP

Answer

Septic shock typically shows decreased SVR with high cardiac output and low filling pressures.

Question 3

A target mean arterial pressure (MAP) of at least what value is recommended during septic shock resuscitation?

Accepted Answer

65 mmHg

Answer

A MAP of at least 65 mmHg is the recommended initial perfusion target.

Question 4

Which physiologic change explains why central venous oxygen saturation (ScvO2) may be elevated in late sepsis?

Accepted Answer

Impaired cellular oxygen extraction at the tissue level

Answer

Cytopathic injury prevents tissues from extracting oxygen, raising venous saturation.

Question 5

A second vasopressor is often added to norepinephrine in refractory septic shock. Which agent is typically chosen?

Accepted Answer

Vasopressin

Answer

Vasopressin is commonly added to norepinephrine to raise MAP and reduce catecholamine dose.
