What is the primary purpose of homeostasis in the human body?
Promote rapid gene mutation
Generate excess body heat
Excrete toxins only
Maintain a stable internal environment
Homeostasis refers to the regulation of the internal environment to maintain stable conditions such as pH, temperature, and electrolyte balance. It is essential for normal cellular function and overall health.
Which term describes an abnormally rapid breathing rate?
Bradypnea
Apnea
Tachypnea
Dyspnea
Tachypnea refers to an increased respiratory rate above the normal range. It can be a response to fever, metabolic acidosis, or hypoxia as the body attempts to expel more CO2.
A hallmark sign of acute inflammation includes which of the following?
Bradycardia
Hyperglycemia
Redness (rubor)
Hypotension
Redness or rubor is caused by increased blood flow to the inflamed tissue. This is one of the five classical signs of inflammation along with swelling, heat, pain, and loss of function.
In type 1 diabetes mellitus, the primary pathophysiologic mechanism is:
Chronic overproduction of insulin
Insulin receptor resistance in peripheral tissues
Autoimmune destruction of pancreatic beta cells
Excess glucagon secretion by alpha cells
Type 1 diabetes results from autoimmune-mediated destruction of insulin-secreting beta cells in the pancreas. This leads to absolute insulin deficiency and hyperglycemia.
What is the normal range for arterial blood pH?
7.25 to 7.35
7.35 to 7.45
7.45 to 7.55
7.10 to 7.30
The normal arterial blood pH range is tightly regulated between 7.35 and 7.45. Deviations outside this range indicate acid-base disturbances requiring compensation.
In congestive heart failure, peripheral edema primarily results from:
Enhanced lymphatic drainage
Reduced interstitial oncotic pressure
Decreased pulmonary capillary permeability
Increased capillary hydrostatic pressure
In heart failure, reduced cardiac output leads to elevated venous and capillary hydrostatic pressure. This pressure forces fluid into the interstitial space causing edema.
Elevated serum troponin levels are most indicative of:
Hepatic necrosis
Myocardial cell injury
Renal failure
Pancreatic inflammation
Troponin proteins are released into the blood when cardiac myocytes are damaged. Elevated troponin is a sensitive marker for myocardial infarction.
Which acid-base disturbance is characterized by increased pH and decreased PaCO2?
Metabolic acidosis
Metabolic alkalosis
Respiratory alkalosis
Respiratory acidosis
Respiratory alkalosis occurs when hyperventilation lowers PaCO2, raising blood pH. This compensatory change can result from anxiety, pain, or high altitude.
During shock, tissue hypoperfusion leads most directly to:
Anaerobic metabolism with lactate buildup
Hyperoxic cellular environment
Increased mitochondrial ATP production
Enhanced aerobic respiration
Reduced tissue perfusion prevents oxygen delivery, forcing cells to rely on anaerobic glycolysis. This produces lactic acid and contributes to metabolic acidosis.
A key diagnostic criterion of nephrotic syndrome is:
Urinary casts with red blood cells
Hematuria on urinalysis
Frequent urinary tract infections
Proteinuria exceeding 3.5 grams per day
Nephrotic syndrome is defined by heavy proteinuria over 3.5 g/day, hypoalbuminemia, hyperlipidemia, and edema. Protein loss in urine leads to decreased plasma oncotic pressure.
In asthma, airway obstruction is primarily due to:
Alveolar wall collapse
Pleural effusion accumulation
Bronchial smooth muscle constriction
Pulmonary capillary rupture
Asthma involves hyperresponsiveness of bronchial smooth muscle causing constriction and airflow limitation. Inflammation and mucus overproduction also contribute.
Which electrolyte disturbance is commonly seen in primary adrenal insufficiency?
Hypocalcemia
Hyperkalemia
Hypokalemia
Hypernatremia
Adrenal insufficiency reduces aldosterone leading to impaired sodium retention and decreased potassium excretion. This causes hyperkalemia and hyponatremia.
The respiratory compensation for metabolic acidosis typically involves:
Decreased respiratory rate
Increased renal bicarbonate loss
Reduced tidal volume
Increased ventilation rate
Metabolic acidosis triggers chemoreceptors that stimulate hyperventilation. Enhanced breathing reduces PaCO2 and helps raise blood pH toward normal.
Elevated B-type natriuretic peptide (BNP) levels most directly reflect:
Ventricular wall stretch from volume overload
Chronic hepatic congestion
Pulmonary parenchymal damage
Pancreatic beta-cell dysfunction
BNP is released by ventricular myocytes in response to increased wall tension. It serves as a diagnostic marker for heart failure severity.
The primary defect in cystic fibrosis is:
Impaired myelin sheath formation
Excessive insulin secretion
Dysfunction of CFTR chloride channels
Abnormal hemoglobin structure
Cystic fibrosis results from mutations in the CFTR gene affecting chloride transport across epithelial cells. This leads to thick secretions in lungs and pancreas.
A patient's arterial blood gas shows pH 7.25, PaCO2 60 mmHg, and HCO3- 26 mEq/L. What is the primary acid-base disturbance?
Metabolic acidosis
Metabolic alkalosis
Acute respiratory acidosis
Respiratory alkalosis
Elevated PaCO2 with low pH indicates respiratory acidosis. Bicarbonate is near normal indicating an acute disturbance without renal compensation.
In diabetic ketoacidosis (DKA), the increase in anion gap primarily results from:
Loss of bicarbonate in urine
Lactic acid accumulation
Increased chloride levels
Accumulation of ketoacid anions
In DKA, excessive ketone bodies such as acetoacetate and beta-hydroxybutyrate accumulate. These organic acids displace bicarbonate leading to a high anion gap metabolic acidosis.
In cirrhosis, ascites formation is mainly due to:
Increased lymphatic drainage
Portal hypertension and hypoalbuminemia
Reduced portal venous resistance
Elevated plasma oncotic pressure
Portal hypertension elevates hydrostatic pressure in the splanchnic circulation while hypoalbuminemia reduces oncotic pressure. Combined forces promote fluid transudation into the peritoneal cavity.
During septic shock, systemic vasodilation is largely mediated by:
Surge in angiotensin II
Elevated vasopressin levels
Nitric oxide release induced by inflammatory cytokines
Endothelin-1 overproduction
Endotoxins and cytokines stimulate inducible nitric oxide synthase, producing high levels of NO. This potent vasodilator leads to vascular collapse in septic shock.
Primary hyperaldosteronism typically presents with:
Hypertension and hypokalemia
Hypotension and hyperkalemia
Hypertension and hypercalcemia
Hypotension and hypokalemia
Excess aldosterone increases sodium reabsorption and potassium excretion. Patients commonly display elevated blood pressure and low serum potassium.
