GI Exam 2 Flashcards
Pathogenic N/V
related to disease
Iatrogenic N/V
stemming from disease treatment (chemo)
Psychogenic N/V
Resulting form psychological state (Stress)
4 causes N/V
pathogenic, iatrogenic, psychogenic, fluid and electrolyte imbalance
Pathophysiology of vomiting
vomiting is caused by stimulation of the chemo-receptor trigger zone which stimulates the vomiting center in the medulla by some type of stimulus
Subjective assessment N/V
patient identifies factors preceding or related to N/V
objective assessment N/V
time of vomiting, color, amount, consistency of emesis, fluid and electrolytes, dehydration
Nurse management of N/V
NPO until tolerate fluids (clear) HOB elevated replace fluid and electrolytes NG tube good mouth care
N/V diet
effervescent fluids, bland food
N/V medications
Zofran (prevent nausea)
Reglan (increase fastric emptying)
Gastritis
inflammation of the fastric mucosa
cause- H Pylori, long term NSAID and steroids, ETOH
Acute Gastritis
S&S: epigastric pain, anorexia, N/V
Dx: H. Pylori testing (stool blood)
Treatment acute gastritis
NPO, fluid and electrolyte replacement
antiemetics
eliminate cause
Chronic gastritis
Recurrent inflammation (autoimmune) no intrinsic factor produced- pernicious anemia closelt associated with gastric CA Tx: avoid irritant, B12 injections for life
Upper GI bleed
atrial- bright red (hematoemesis)
venous- slow ooz (coffee ground emesis)
