A patient in compensated shock is most likely to exhibit which skin
condition?
A. Warm and flushed skin
B. Cold and clammy skin
C. Cyanotic extremities
D. Mottled and necrotic skin - correct answer- B. Cold and clammy
skin
Rationale: Peripheral vasoconstriction reduces skin perfusion, making
the skin cold and clammy.
A patient in the intermediate phase (24-72 hours post-injury) of MODS
develops severe hypoxemia, increased work of breathing, and requires
mechanical ventilation. Which complication is most likely occurring?
A. Acute Respiratory Distress Syndrome (ARDS)
B. Pulmonary embolism
C. Cardiogenic shock
D. Neurogenic shock - correct answer- A. Acute Respiratory Distress
Syndrome (ARDS)
,Rationale: ARDS is a common complication in the intermediate phase of
MODS, occurring due to increased capillary permeability in the lungs,
leading to pulmonary edema and impaired gas exchange.
A patient with cardiogenic shock is most likely to exhibit which
hemodynamic parameter?
A) Increased preload with decreased cardiac output
B) Increased cardiac output with decreased preload
C) Low systemic vascular resistance (SVR)
D) Increased urine output - correct answer- A) Increased preload
with decreased cardiac output
Rationale: In cardiogenic shock, decreased myocardial contractility leads
to increased preload and reduced cardiac output.
An anaphylactoid reaction differs from an anaphylactic reaction in that
it:
A. Is mediated by IgE antibodies
B. Does not involve IgE antibodies
C. Only occurs with drug allergens
D. Is always less severe - correct answer- B. Does not involve IgE
antibodies
,Rationale: An anaphylactoid reaction mimics anaphylaxis but occurs
without the involvement of IgE antibodies, often triggered by factors like
medications and exercise.
Angioedema in anaphylaxis most commonly affects which areas of the
body?
A. Hands and feet
B. Lips, face, and throat
C. Abdomen and back
D. Legs and arms - correct answer- B. Lips, face, and throat
Rationale: Angioedema often affects the lips, face, and throat, posing a
significant risk for airway obstruction.
In anaphylactic shock, which immune cells primarily release histamine
and other inflammatory mediators?
A. Neutrophils and macrophages
B. Mast cells and basophils
C. B cells and T cells
D. Eosinophils and dendritic cells - correct answer- B. Mast cells and
basophils
, Rationale: Mast cells and basophils degranulate upon allergen exposure,
releasing histamine and other mediators that cause vasodilation,
increased capillary permeability, and bronchoconstriction.
In compensated shock, blood is primarily shunted away from which of
the following organs?
A. Brain and heart
B. Kidneys and liver
C. Lungs and spleen
D. Adrenal glands and pancreas - correct answer- B. Kidneys and
liver
Rationale: Blood is redirected to vital organs like the brain and heart,
while non-essential organs such as the kidneys and liver experience
reduced perfusion.
In the chronic phase (21+ days post-injury) of MODS, what is the most
common clinical trajectory for survivors?
A. Rapid recovery with complete organ function restoration
B. Gradual improvement with prolonged rehabilitation needs
C. Immediate resolution of systemic inflammation
D. Minimal risk of long-term complications - correct answer- B.
Gradual improvement with prolonged rehabilitation needs
