NUR2243 Exam 3 Questions and Answers Already Passed Latest Update 2025-2026
Shock - Answers Perfusion impairment!
MAP - Answers mean arterial pressure
Arterial perfusion
2(dbp) + SBP / 3
WNL= 70-100
DECREASE COULD INDICATE SHOCK
Pulse Pressure (PP) - Answers Psystolic-Pdiastolic
Narrowed = <20
Early septic shock & dec stroke volume
Hypovolemic shock - Answers Loss of circulating blood decreases MAP= loss of body perfusion
cardiogenic shock - Answers Pump failure!
Caused by MI
cardiac dz
Obstructive shock - Answers Inadequate filling or contraction of the heart muscle due to external factors
Ex: pericarditis, cardiac tamponade, stab wound
distributive shock - Answers Low BP includes Septic (severe infection), Neurogenic (damage to the spinal
cord), Anaphylactic (reaction to substance), Psychogenic (feinting)
septic - Answers Life threatening organ dysfunction caused by D regulated host response to infection
Most common causes of sepsis - Answers • Reduced immunity
Central lines
Staph, pseudomonas aeruginosa, e-coli
What is in a 1 hour sepsis bundle ? - Answers Measure lactic acid, blood cultures prior to antibiotic adm ,
broad-spectrum antibiotics, begin rapid administration of crystalloid fluids for hypotension, or lactate,
vasopressors if hypotension after fluid resuscitation to maintain MAP
First stage of shock? - Answers Initial stage
Baseline map decreases by 10.
, Slight increase in respiratory rate, heart rate and diastolic blood pressure
Symptoms of shock are difficult to detect !
Second stage of shock? - Answers Compensatory
• Tissue hypoxia in non-vital organs
• Gl tract, skin - STILL REVERSIBLE
• hyperkalemia
• Pt. is thirsty! Anxious! Tachy!
Falling systolic with Rising Diastolic!!!
Can be reversible!
RN recognizes changes and mobilizes health care team.
Third stage of shock? - Answers Progressive stage
Sustained dec in MAP of 20.
Hyperkalemia
Conditions causing shock must be corrected within 1 hour
Fourth stage of shock? - Answers Refractory stage
Too little oxygen reaches tissues
It's too late for the party to respond effectively to interventions, nonpalpable pause, dusky extremities,
unmeasurable O2 saturation and MODS
DEATH
MODS - Answers Sequence of cell damage
Massive release of toxic metabolites an enzymes
DIC
Myocardial depressant factor released from an ischemic pancreas, decrease cardiac contractility
MODS Interventions - Answers Oxygen therapy!
IVF Therapy- NS or RL
Drug therapy/ improve CO
