Question 1

During the systemic inflammatory response in shock, which specific outcome is directly caused by the release of proinflammatory mediators like TNF and IL-1?

Accepted Answer

Increased capillary permeability

Answer

Decreased systemic vascular resistance

Answer

Enhanced oxygen-hemoglobin affinity

Answer

Suppression of the coagulation cascade

Question 2

In the initial stage of shock, the body's compensatory mechanisms are sufficient to maintain perfusion despite a drop in mean arterial pressure (MAP) of up to 15 mmHg.

Accepted Answer

False

Answer

True

Question 3

Which of the following clinical findings are classified as late signs of shock indicating severe systemic compromise?

Answer

Tachycardia

Answer

Mottled skin

Answer

Flat neck veins

Answer

Unresponsiveness

Answer

Tachypnea

Question 4

What is the primary consequence of sodium-potassium pump failure during the progressive stage of shock?

Accepted Answer

Cellular swelling

Answer

Increased lactic acid clearance

Answer

Enhanced mitochondrial respiration

Answer

Stabilization of the cell membrane

Question 5

During the compensatory stage of shock, the sympathetic nervous system acts to increase both cardiac output and systemic vascular resistance to maintain blood pressure.

Accepted Answer

True

Answer

False

Question 6

A patient presents with a suspected infection and a serum lactate level of 4.5 mmol/L. Based on current definitions, which clinical classification is most appropriate?

Accepted Answer

Septic shock

Answer

SIRS

Answer

Sepsis

Answer

Severe sepsis

Question 7

Which of the following actions are considered immediate priorities within the first hour of managing a patient with suspected sepsis?

Answer

Obtaining two sets of blood cultures

Answer

Administering broad-spectrum intravenous antibiotics

Answer

Initiating 30 mL/kg crystalloid fluid resuscitation

Answer

Starting immediate parenteral nutrition

Question 8

In the management of septic shock, the target Central Venous Pressure (CVP) range is 8-12 mmHg to guide adequate fluid resuscitation.

Accepted Answer

True

Answer

False

Question 9

Which pharmacological agent is recommended as the first-line vasopressor for a patient who remains hypotensive despite adequate fluid resuscitation?

Accepted Answer

Norepinephrine

Answer

Dopamine

Answer

Epinephrine

Answer

Phenylephrine

Question 10

What is the primary rationale for maintaining blood glucose levels between 140-180 mg/dL in patients with septic shock?

Accepted Answer

To prevent the complications associated with both hypoglycemia and severe stress-induced hyperglycemia

Answer

To maximize cellular oxygen uptake

Answer

To reduce the requirement for exogenous insulin therapy

Answer

To directly lower serum lactate levels

Question 11

Which hemodynamic parameter is most likely to be elevated in a patient experiencing cardiogenic shock due to acute left ventricular failure?

Accepted Answer

Pulmonary Artery Wedge Pressure (PAWP)

Answer

Systemic Vascular Resistance (SVR)

Answer

Cardiac Output (CO)

Answer

Mixed Venous Oxygen Saturation (SvO2)

Question 12

Which of the following clinical conditions are recognized as primary causes of obstructive shock?

Answer

Cardiac tamponade

Answer

Tension pneumothorax

Answer

Massive pulmonary embolism

Answer

Severe anaphylaxis

Question 13

In the management of a pregnant patient in shock, the left lateral tilt position is utilized primarily to prevent aortocaval compression by the gravid uterus.

Accepted Answer

True

Answer

False

Question 14

Which physiological mechanism explains the bradycardia observed in neurogenic shock following a high-level spinal cord injury?

Accepted Answer

Loss of sympathetic outflow to the heart

Answer

Excessive vagal stimulation from intracranial pressure

Answer

Direct myocardial depression from catecholamine depletion

Answer

Compensatory baroreceptor reflex activation

Question 15

In pediatric patients, the presence of hypotension is considered an early, reliable indicator of compensated shock.

Accepted Answer

False
