Q1 QUESTION 1 OF 165

,What is pagophagia?
CORRECT ANSWER
A craving to chew ice
RATIONALE
Pagophagia is characterized by a compulsive craving to consume ice, often associated with iron deficiency anemia, reflecting a possible underlying
nutritional deficiency or psychological condition. This phenomenon illustrates the body's response to unmet nutritional needs, prompting specific
cravings.
Q2 QUESTION 2 OF 165
What is disseminated intravascular coagulation (DIC)?
CORRECT ANSWER
A life-threatening condition in which blood clotting proteins become overactive causing widespread blood clots. This excessive clotting rapidly
depletes platelets and increases clot dissolving mechanisms, leading to severe uncontrollable bleeding.
RATIONALE
DIC results from a pathological activation of the coagulation cascade, leading to the formation of microthrombi throughout the vasculature, which
consumes platelets and coagulation factors, ultimately precipitating a paradoxical bleeding diathesis. This complex interplay highlights the critical
balance between coagulation and fibrinolysis in maintaining hemostatic function.
Q3 QUESTION 3 OF 165
What is the pathophysiology of disseminated intravascular coagulation (DIC)?
CORRECT ANSWER
Injury triggers an imbalance between clotting and fibrinolysis. Clotting factors, thrombin, & platelets accumulate throughout the cardiovascular
system. Clotting mechanisms become depleted, resulting in massive systemic hemorrhage.
RATIONALE
Disseminated intravascular coagulation (DIC) results from widespread endothelial injury that activates coagulation pathways, leading to excessive
thrombin generation and platelet consumption. This imbalance culminates in systemic clot formation, followed by depletion of clotting factors and
subsequent hemorrhagic complications as the body's hemostatic mechanisms become overwhelmed.
Q4 QUESTION 4 OF 165
How is disseminated intravascular coagulation (DIC) initiated?
CORRECT ANSWER
Endothelial injury results in thrombus formation.
RATIONALE
Endothelial injury triggers the coagulation cascade, leading to the excessive formation of thrombi and consumption of clotting factors, which
characterizes disseminated intravascular coagulation. This process highlights the critical role of vascular health in maintaining hemostatic balance.

, Q5 QUESTION 5 OF 165
What are the clinical manifestations of disseminated intravascular coagulation (DIC)?
CORRECT ANSWER
Widespread hemorrhaging (bruising, petechiae, epistaxis)
Hypovolemic shock
Headache, seizures, coma
Renal failure
Dyspnea
RATIONALE
Disseminated intravascular coagulation (DIC) results in widespread clotting and subsequent bleeding due to the consumption of clotting factors, leading
to manifestations such as petechiae and hypovolemic shock. The systemic effects, including renal failure and neurological symptoms like seizures, arise
from impaired perfusion and microvascular thrombosis.
Q6 QUESTION 6 OF 165
What are the steps in the process of clotting?
CORRECT ANSWER
Hemorrhage
Platelet activation
Clotting cascade
Platelet stabilization
Fibrinolysis
RATIONALE
Initiation of clotting begins with hemorrhage leading to platelet activation, which aggregates and initiates the clotting cascade. This cascade culminates
in the stabilization of the platelet plug, followed by fibrinolysis to regulate and resolve the clot, demonstrating the dynamic balance of hemostasis.
Q7 QUESTION 7 OF 165
What is spinal shock?
CORRECT ANSWER
The temporary loss of of neurological activity below the level of an acute spinal cord injury. It is a physiological response to spinal cord trauma,
often masking the true, permanent severity of the injury until reflexes begin to return.
RATIONALE
Spinal shock occurs as a physiological response characterized by the transient loss of reflexes and neurological function below the level of an acute spinal
cord injury, which can obscure the actual extent of permanent damage until reflex activity resumes. This phenomenon highlights the distinction between
immediate neurological deficits and the potential for long-term recovery following spinal cord trauma.
Q8 QUESTION 8 OF 165

, What are the clinical manifestations of traumatic brain injury (TBI)?
CORRECT ANSWER
Neurological - Seizures, concussion, confusion
Structural - Hematoma, edema, skulll fracture
Physiological - Increased ICP, respiratory depression, brainstem herniation
RATIONALE
Traumatic brain injury presents a spectrum of manifestations across neurological, structural, and physiological domains, reflecting the complex interplay
of neurochemical changes, physical damage, and altered intracranial dynamics. Recognizing these diverse symptoms is critical for timely intervention and
management of TBI complications, such as increased intracranial pressure and potential herniation.
Q9 QUESTION 9 OF 165
What are the stages of multiple sclerosis?
CORRECT ANSWER
Stage 1 - Clinically isolated syndrome (CIS)
Stage 2 - Relapsing-remitting
Stage 3 - Primary progressive
Stage 4 - Secondary progessive
RATIONALE
Multiple sclerosis progresses through distinct phases characterized by varying clinical manifestations; clinically isolated syndrome (CIS) marks the initial
presentation, followed by relapsing-remitting, primary progressive, and secondary progressive stages, reflecting the disease's evolution and impact on
neurological function. Understanding these stages aids in appropriate management and treatment strategies tailored to disease progression.
Q10 QUESTION 10 OF 165
What are cheyne-stokes respirations?
CORRECT ANSWER
A breathing pattern that alternates between hyperpnea and periods of apnea.
RATIONALE
Cheyne-Stokes respirations are characterized by a cyclical pattern where breathing becomes progressively deeper (hyperpnea) followed by a complete
cessation of breath (apnea), often indicative of underlying neurological or cardiac dysfunction. This pattern reflects the brain's impaired regulation of
respiratory control, particularly in response to changes in carbon dioxide and oxygen levels.
Q11 QUESTION 11 OF 165
What is the inheritance pattern of cystic fibrosis?
CORRECT ANSWER
Autosomal recessive
