Pathophysiology-Unit 3

Legionaires' disease is caused by
a gram-negative bacterium
Describe lobar pneumonia
sudden onset of fever & chills with rales and rusty sputum
Histoplasmosis is caused by
a fungus
T or F : Faliure to excrete meconium is a common idicator of CF in newborns
T of F: Cystic Fibrosis is transmitted by an autosomal dominant gene
False, the gene is recessive
T of F: Destruction of alveolar walls and septae is typical of acute asthma
False, it is typical of emphysema
Chronic bronchitis is caused by
chronic irritation, infammation and infection of the larger airways
T of F: type 1 hypersensitivity reaction is the basis for acute attacks of extrinsic asthma
T or F: Caseation necrosis and formation of a tubercle identifies primary TB
Emphysema is NOT when
ventilation/perfusion ratio remains constant
Pathological changes with bronchiectasis include
airway obstruction and weak, dilated bronchial walls
T or F: Wheezing and stridor would be significant signs of bronchiectasis
False, Significant signs of bronchiectasis include chronic cough producing large quantizes of purulent sputum.
T or F: Thrombus forming in the deep vein of the leg is a common source of pulmonary embolus
A large sized pulmonary embolus is likely to cause
hypotension and right sided heart failure
T or F: the mediastinum shifts toward the unaffected side during inspiration in a flail chest injury
T or F: Retention of fluid in the lungs causes respiratory distress syndrome in infants
False, Infant respiratory distress syndrome can result from insufficient surfactant production.
T or F: Decreased bicarbonate ion is the first change in arterial blood gases with diarrhea.
T or F: Increased excretion of hydrogen ions is initially caused by vomiting
False, initially caused by metabolic alkalosis.
Common causes of hiatal hernia include
increased intra-abdominal pressure
allergy to shellfish is likely to develope
acute gastritis
T of F: High cholesterol concentration in the bile is a predisposing factor to cholelithiasis
The most common type of hepatitis transmitted by blood transfusion is
Hepatitis C of HCV
Acute pancreatitis causes massive inflammation and necrosis due to
activation and spread of proenzymes
T of F: Acute appendicitis is usually initiated by obstruction of the lumen of the appendix
Hypovolemic shock develops with intestinal obstruction as a result of
vomiting and intestinal distension
What do both hypokalemia and hyperkalemia cause?
cardiac arrythmias
Metabolic acidosis is commonly seen in which disease/condition?
diabetes mellitus
What would a serum pH of 7.33 in a patient with kidney disease indicate?
metabolic acidosis
