Study Notes

Gastrointestinal Drugs

  •  Gastrointestinal (GI) tract anatomy diagram shown, including sections like the RUQ, LUQ, RLQ, LLQ, liver, stomach, spleen, duodenum, pancreas, ascending colon, transverse colon, descending colon, small intestine, rectum, and anus.
  •  GI drugs focus on conditions like vomiting, diarrhea, and constipation.

Vomiting

  •  Vomiting (emesis) is the expulsion of gastric contents.
  •  Causes include motion sickness, viral/bacterial infections, food intolerance, surgery, pregnancy, pain, shock, certain drugs (e.g., antineoplastics, antibiotics), radiation, and middle ear disturbances.
  • Nausea may or may not precede vomiting.
  • Nonpharmacologic methods for decreasing nausea/vomiting: weak tea, flat soda, gelatin, Gatorade, Pedialyte (for children), crackers, and dry toast.
  • IV fluids for severe dehydration.

Antiemetics

  •  Types of antiemetic drugs included in the notes are shown.
  • Nonprescription antiemetics (e.g., Cyclizine, Dimenhydrinate, Meclizine ) and prescription antiemetics (e.g., Promethazine) are discussed
  • Each has specific uses, considerations (like possible side effects, interactions with alcohol, pregnancy categories), and potential adverse reactions.

Adverse Reactions

  • Prescription antiemetics can have adverse reactions, including extrapyramidal syndrome, seizures, and life-threatening conditions.

Diarrhea

  • Diarrhea is frequent liquid stool, a symptom of an intestinal disorder.
  • Intestinal fluids are rich in water, sodium, potassium, and bicarbonate, causing potential dehydration and electrolyte imbalances.
  • Patients with diarrhea should avoid milk products and foods high in fat.
  • Nonpharmacologic treatment: clear liquids (Gatorade, Pedialyte) and oral solutions; IV electrolyte solutions if necessary to treat until the underlying cause is determined.
  • Antidiarrheal drugs combined with nonpharmacologic treatment.

Travelers' Diarrhea

  • A type of acute diarrhea, usually caused by E. coli.
  • It typically lasts less than two days.
  • For severe cases, fluoroquinolone antibiotics are generally prescribed.
  • Loperamide can help slow peristalsis and decrease defecation frequency.
  • Prevention includes drinking bottled water, washing fruit, and eating cooked vegetables.

Antidiarrheals

  • Different types of antidiarrheal drugs, including opiates, adsorbents, and miscellaneous agents are included.
  • Side effects of specific antidiarrheal drugs (e.g., drowsiness, dizziness, constipation, confusion).
  • Special considerations for these drugs include warnings against concurrent use with CNS depressants and precautions for patients with glaucoma.

Nursing Interventions (Vomiting, Diarrhea)

  • Vital sign monitoring is crucial, especially for severe conditions.
  • Bowel sounds should be noted.
  • Frequent mouth care for patients experiencing vomiting.
  • Addressing dehydration/electrolyte imbalances.
  • Cautious administration of antidiarrheal drugs for specific patient populations (e.g., pregnant patients, those with glaucoma, liver disorders).

Constipation

  • Constipation is the accumulation of hard fecal material in the large intestine, a common complaint for older adults.
  • Contributing factors include insufficient water intake and poor dietary habits.
  • Nonpharmacological management includes diet, high fiber, water, exercise, and routine bowel habits.

Laxatives

  • Laxatives and cathartics help evacuate fecal matter.
  • Laxatives promote soft stools; cathartics lead to watery stools (often with cramping). Drug dosage categorizes the effect, either laxative or cathartic.
  • Four main types of laxatives are discussed (osmotics, stimulants, bulk-forming, and emollients).

Specific Laxative Types

  • Osmotic (saline): include salts, lactulose, and glycerin; Hyperosmolar salts draw water into the colon, increasing fecal bulk and stimulating peristalsis.
  • Stimulant (contact): examples are bisacodyl, senna, and castor oil; increase peristalsis by irritating nerve endings.
  • Bulk-forming: natural fibers absorb water, increasing fecal bulk; results in large, soft stools.
  • Emollients (stool softeners): examples are docusate calcium, magnesium, and others; lower surface tension to promote water accumulation in the intestines.

Side Effects and Adverse Reactions of Laxatives

  • Side effects: Specific types of laxatives can have side effects, including nausea, vomiting, diarrhea, and cramping.
  • Adverse reactions can range from mild cramping to more serious effects like electrolyte imbalances, dehydration, and kidney problems.

Nursing Considerations & Patient Teaching regarding Laxatives

  • Nursing should monitor patient care and intake.
  • Patients should be instructed to increase water intake before and after.
  • Overuse should be avoided.
  • Time scheduled administration is advised.
  • Drug should be instructed to be swallowed whole and not chewed.
