Which of the following statements accurately describes Multiple Organ Dysfunction Syndrome (MODS)?
MODS can be diagnosed when one organ system fails for more than 24 hours.
MODS is the failure of 2 or more organ systems in an acutely ill patient.
MODS is the sequential failure of organ systems in a healthy individual.
MODS is the failure of a single organ system due to chronic illness.
The Correct Answer is B
A. MODS can be diagnosed when one organ system fails for more than 24 hours:
This describes single organ failure, not MODS.
B. MODS is the failure of 2 or more organ systems in an acutely ill patient:
This is the correct definition of MODS. It is a progressive, life-threatening condition often resulting from sepsis, trauma, or shock.
C. MODS is the sequential failure of organ systems in a healthy individual:
MODS develops in critically ill patients, not healthy individuals, typically due to an overwhelming insult like infection or trauma.
D. MODS is the failure of a single organ system due to chronic illness:
Chronic organ failure is not MODS. MODS is acute and involves multiple organs.

Correct Answer is C
Explanation
A. Septic shock:
Septic shock results from infection-induced vasodilation and capillary leak. It’s not related to blood loss.
B. Obstructive shock:
Obstructive shock is due to mechanical blockage of blood flow, such as in pulmonary embolism or cardiac tamponade. It is not caused by hemorrhage.
C. Hypovolemic shock:
This type of shock is due to loss of intravascular volume, such as hemorrhage. A postoperative blood loss of 800 mL with declining BP fits this condition.
D. Neurogenic shock:
This is caused by spinal cord injury leading to loss of sympathetic tone and hypotension with bradycardia, not blood loss.
Correct Answer is D
Explanation
A. Administering antibiotics:
Antibiotics are not used unless infection is suspected. Heat stroke is not an infectious condition.
B. Monitoring blood glucose levels:
While monitoring glucose may be part of general care, it is not the priority in heat stroke.
C. Providing hydration through oral fluids:
Oral fluids are contraindicated in unconscious or altered patients, which is often the case in heat stroke. IV fluids are preferred.
D. Rapid cooling of the body:
The primary concern in heat stroke is core temperature reduction to prevent organ damage. Ice packs, cooling blankets, and cold IV fluids are used.
