Nursing Care & Priorities for Those in ShockKeith Rischer RN, MA, CEN

2

Todays Objectives

Compare and contrast pathophysiology & manifestations of the various shock states and the physiologic compensatory mechanisms.

Identify nursing priorities with the various shock states. Compare & interpret abnormal laboratory test indicators

involved with septic, hypovolemic, and cardiogenic shock.

Analyze assessment data to determine nursing diagnoses and formulate a plan of care for clients with the various shock states.

Describe the medical management and mechanism of action, side effects and nursing interventions of pharmological management with shock states.

Compare & contrast pathophysiology, manifestations, nursing priorities seen with sepsis vs. Multiple Organ Dysfunction Syndrome (MODS).

Shock Defined

Any problem that impairs oxygenation delivery to tissues & organs

CV system is where it begins

Table 40-3 p.826• Hypovolemic• Cardiogenic• Distributive

Neurogenic Anaphylactic Septic-SIRS Multiple Organ Dysfunction Syndrome (MODS)

4

Processes of Shock Table 40-2 p.825

Initial stage…early shock• MAP decrease 5-10mm/Hg• Mild vasoconstriction• Tachycardic…Why???

Nonprogressive stage…compensatory stage• MAP decrease 10-15 mm/Hg• Mod. Vasoconstriction• Physiologic compensations

Renin, aldosterone, ADH Decreased u/o Mild acidosis Mild hyperkalemia

5

Processes of Shock Table 40-2 p.825

Progressive stage…intermediate stage• MAP decrease >20mm/Hg• Overall metabolism-anaerobic

Moderate acidosisModerate hyperkalemiaTissue ischemia lactic acidosis-Lactate

Refractory stage…irreversible stage

6

Hypovolemic Shock:Physical Assessment

Cardiovascular changes• Pulse• Blood pressure

Skin changes Respiratory changes

• Oxygen saturation• RR

Renal and urinary changes Central nervous system changes

7

Hypovolemic Shock:Nursing Priorities

Impaired gas exchange• Nursing interventions

Deficient fluid volume• Nursing interventions

Decreased cardiac output• Nursing interventions

Risk for ineffective tissue perfusion• Body systems impacted???• Nursing interventions

8

Sepsis

Patho Progressive

• Infection • Bacteremia• Systemic Inflammatory

Response Syndrome (SIRS)

• Sepsis• Severe sepsis• Septic shock• Multiple Organ Dysfunction

Syndrome (MODS)

9

Sepsis:Hyperdynamic (early)

Cardiovascular changes Skin changes Respiratory changes Renal and urinary changes Central nervous system changes

10

Sepsis:Hypodynamic (late)

Cardiovascular changes Skin changes Respiratory changes Renal and urinary changes Central nervous system changes

General Shock: Nursing Interventions Remember A,B,C,D

Reverse the shock• Administer O2• Establish IV access

Restore fluid volume• Colloid• Crystalloid

Vasoactive gtts Administer blood products as ordered Nursing assessment

• Pulse/rhythm• BP-CVP• RR-O2 sats• Urine output• Skin color• Monitor labs

Septic Shock: Nursing Interventions

All the same as previous slide and… Obtain blood, urine cultures as ordered Administer IV abx Administer anti-arrythmics Aggressive IV fluid resuscitation Assess closely for signs of bleeding…DIC Strict aseptic technique Fever reduction as needed Client-family education
