small and large intestines, rectum, and anus.
Accessory organs of the GI - ANSWER: The liver, gallbladder, and pancreas
Functions of the upper GI - ANSWER: Chewing, swallowing, and breaking down food
particles.
Risk factors for oral cancer - ANSWER: Cigarette smoking, tobacco use, pipe smoking,
excessive alcohol use, infection with HPV, and genetic predisposition
Signs and symptoms of oral cancer - ANSWER: Lesions on the tongue or mucosa,
sores or discoloration of the lips or mouth that don't heal
treatment of oral cancer - ANSWER: radiation, chemotherapy, surgery that may
require the creation of a tracheostomy
Nursing care of a patient with oral cancer - ANSWER: Involves monitoring respiratory
status, nutritional support, and comfort measures
Esophageal cancer/ gastric cancer risk factors - ANSWER: Smoking, excessive alcohol
use
cause of esophageal cancer - ANSWER: Barrett esophagus
Barrett esophagus - ANSWER: Precancerous condition due to longstanding GERD, the
constant irritation of the esophagus by stomach fluids can cause cells to become
malignant.
Signs and symptoms of esophageal cancer - ANSWER: dysphagia, hoarseness,
persistent cough, halitosis, regurgitation of foods, and weight loss.
Treatment of esophageal cancer - ANSWER: Endoscopic therapies and surgeries.
Esophagectomy is less commonly done due to complication rate
respiratory acidosis - ANSWER: A drop in blood pH due to hypoventilation (too little
breathing) and a resulting accumulation of Co2.
respiratory alkalosis - ANSWER: Arise in blood pH due to hyperventilation (excessive
breathing) and a resulting decrease in CO2.
, metabolic acidosis - ANSWER: decreased pH in blood and body tissues as a result of
an upset in metabolism
metabolic alkalosis - ANSWER: elevation of HCO3- usually caused by an excessive loss
of metabolic acids
respiratory acidosis - ANSWER: Causes: shallow, slow respirations-> HYPOventilation;
respiratory congestion or obstruction.
Can be due to COPD, severe pneumonia, or excessive sedation; respiratory muscle
weakness.

headache; confusion; malaise
ABG values for metabolic acidosis - ANSWER: low pH, HCO3 less than 22
Causes of respiratory alkalosis - ANSWER: HYPERventilation caused by anxiety or
pain, mechanical ventilation

35
metabolic alkalosis causes - ANSWER: vomiting; prolonged gastric suction;
hypokalemia; medications: diuretics, antacids or bicarbonate, mineralocorticoids
signs and symptoms of metabolic alkalosis - ANSWER: Hypoventilation; confusion;
numbness/tingling; decreased LOC
