Which of the following is the primary cellular response in acute inflammation?
Fibroblast proliferation
Lymphocyte activation
Neutrophil infiltration
Collagen deposition
Neutrophil infiltration is the hallmark cellular response in acute inflammation, arriving early to phagocytose pathogens and debris. Other cells like fibroblasts and lymphocytes play roles in later or chronic phases.
An elevated serum creatinine level is most indicative of which physiological alteration?
Improved cardiac output
Reduced glomerular filtration rate
Increased insulin sensitivity
Enhanced liver synthetic function
Creatinine is cleared by glomerular filtration, so an elevated level reflects a reduced filtration rate and impaired renal function. It is not directly related to liver, insulin sensitivity, or cardiac output.
Which clinical sign is most characteristic of acute hypoglycemia?
Bradycardia
Diaphoresis (sweating)
Polyuria
Weight gain
Diaphoresis occurs due to sympathetic activation in hypoglycemia, leading to sweating. Polyuria and weight gain are more typical of hyperglycemia, and bradycardia is not a classic sign.
What term best describes programmed cell death without inflammation?
Autolysis
Oncosis
Apoptosis
Necrosis
Apoptosis is a controlled mechanism of cell death that does not elicit inflammation. Necrosis and oncosis involve uncontrolled cell death and provoke inflammatory responses.
In early hypovolemia, which compensatory mechanism is activated first to maintain perfusion?
Bradycardia
Tachycardia
Vasodilation
Hypoventilation
Tachycardia is the first compensatory response to hypovolemia, increasing heart rate to maintain cardiac output. Vasodilation and bradycardia would worsen perfusion, and hypoventilation is unrelated.
Polyphagia in a patient with type 1 diabetes is primarily due to which mechanism?
Increased insulin sensitivity
Enhanced glycogen storage
Excess lipid oxidation
Cellular glucose starvation
In type 1 diabetes, lack of insulin prevents glucose uptake, causing cellular starvation and triggering excessive hunger (polyphagia). Insulin sensitivity is reduced, not increased.
An arterial blood gas shows pH 7.30, PaCO2 50 mmHg, HCO3− 24 mEq/L. What acid - base disturbance is present?
Metabolic alkalosis
Metabolic acidosis
Respiratory acidosis
Respiratory alkalosis
The elevated PaCO2 and low pH indicate CO2 retention causing respiratory acidosis. Bicarbonate is normal, ruling out primary metabolic disturbances.
Which laboratory pattern is most consistent with a hemolytic anemia?
High MCV
Elevated indirect bilirubin and LDH
Low reticulocyte count
Increased haptoglobin
Hemolysis releases hemoglobin, raising indirect bilirubin and lactate dehydrogenase (LDH) while consuming haptoglobin. Reticulocyte count usually increases, and MCV is unchanged.
In left-sided heart failure, increased preload most directly leads to which complication?
Pulmonary edema
Peripheral cyanosis
Hepatomegaly
Jugular venous distension
In left-sided failure, elevated preload raises pulmonary capillary hydrostatic pressure, causing fluid to leak into alveoli and produce pulmonary edema. Jugular distension and hepatomegaly are right-sided signs.
Which complement component initiates the classical activation pathway?
Factor B
C1q
C5b
C3a
C1q binds antigen - antibody complexes to initiate the classical complement pathway. C3a and C5b are later in the cascade, and Factor B is part of the alternative pathway.
A patient in early septic shock often presents with warm, flushed skin due to which mechanism?
Systemic vasodilation
Increased blood viscosity
Microvascular thrombosis
Cutaneous vasoconstriction
Septic shock causes widespread vasodilation from inflammatory mediators, resulting in warm, flushed skin. Vasoconstriction or thrombosis would produce cool, pale skin.
Chronic hypoxia at high altitude stimulates polycythemia by increasing which hormone?
Calcitonin
Thrombopoietin
Erythropoietin
Renin
Hypoxia-inducible factors in the kidney raise erythropoietin production, stimulating red blood cell synthesis. Renin affects blood pressure and thrombopoietin affects platelets.
The primary immune response against a viral infection is mediated by which mechanism?
IgE antibody production
Cell-mediated cytotoxicity
B-cell neutralization
Complement opsonization
Cytotoxic T cells provide cell-mediated immunity crucial for eliminating virus-infected cells. IgE is involved in allergic responses and complement plays a minor role.
Which term best describes an increase in tissue cell number in response to chronic stimulus?
Metaplasia
Dysplasia
Hypertrophy
Hyperplasia
Hyperplasia is the increase in cell number due to a stimulus. Hypertrophy is cell size increase, metaplasia is cell type change, and dysplasia is disordered growth.
A patient with metabolic acidosis will most likely exhibit which respiratory compensation?
Apnea
Hypoventilation
Hyperventilation
Cheyne - Stokes respirations
The respiratory system compensates for metabolic acidosis by increasing ventilation to lower PaCO2 and raise pH. Hypoventilation or apnea would worsen acidosis.
In cirrhosis-induced hypoalbuminemia leading to ascites, what is the primary pathophysiological mechanism?
Decreased plasma oncotic pressure
Enhanced protein synthesis
Increased capillary hydrostatic pressure
Elevated lymphatic absorption
Low albumin reduces oncotic pressure, allowing fluid to accumulate in the peritoneal cavity. Increased hydrostatic pressure is more related to portal hypertension, and lymphatic function is impaired.
Which alteration in the alveolar - capillary membrane is characteristic of ARDS and impairs gas exchange?
Reduced surfactant clearance
Increased membrane thickness due to fibrin deposition
Decreased pulmonary capillary pressure
Alveolar hyperplasia
In ARDS, fibrin and protein leak thicken the alveolar - capillary barrier, reducing diffusion. Capillary pressure may be normal, and alveolar hyperplasia is not a feature.
In SIADH, which laboratory pattern is most characteristic?
Low serum osmolality and high urine osmolality
Elevated BUN with low urine sodium
Increased serum osmolality and low urine output
High serum sodium and dilute urine
SIADH causes excessive ADH, leading to water retention, low serum osmolality, and concentrated urine with high osmolality. Sodium is diluted, not elevated.
Despite total body depletion of potassium in diabetic ketoacidosis, why is serum potassium often elevated?
Increased aldosterone secretion
Enhanced K+ excretion by kidneys
Insulin deficiency causes extracellular K+ shift
Cellular uptake of K+
Without insulin, potassium shifts from intracellular to extracellular space, raising serum levels. Aldosterone would promote excretion, and cellular uptake requires insulin.
Which event represents the earliest step in atherogenesis?
Endothelial dysfunction with increased permeability
Fibrous cap formation
Thrombosis within the plaque
Smooth muscle proliferation
Endothelial injury increases permeability, allowing LDL infiltration and triggering inflammation. Smooth muscle proliferation and cap formation occur later in plaque maturation.
