Bisacodyl is a: stimulant laxative, it stimulates peristalsis, it is used for colonoscopy prep, also for short term use of constipation. A client who has constipation is prescribed bisacodyl suppository. The nurse explains that bisacodyl does what? Acts on smooth intestinal muscle to increase bulk and peristalsis. ❖ Teaching: Ileostomy Surgical opening of the ileum to drain stool. Post op: ASSESS! Teach about dietary changes and appliances that can help manage gas and odor. Foods that decrease odor: buttermilk, cranberry juice, parsley, and yogurt. Foods that decrease Gas: yogurt, crackers, and toast. Teach to watch for indications of stoma ischemia (pale pink/bluish purple color and dry appearance or necrosis (black or purple in color) QUESTIONS: ❖ Immediately after having surgery to create an ileostomy, which goal has the highest priority?

Drainage gradually thickens and becomes yellow to brown. ❖ Instruct to empty pouch: when ⅓ to ½ is full. Advise use of skin barrier and prompt attention to signs of leakage. ❖ A nurse is teaching a patient with a new ileostomy about incorporating preventive strategies at home. To prevent excoriation and breakdown of the peristomal skin, the nurse should instruct the patient to: Empty pouch when it’s no more than half full ❖ A nurse is providing preoperative teaching for a patient who has colon cancer. The surgeon informed the patient that his entire large intestine and rectum will be removed. The nurse should explain the type of ostomy he will have is: Ileostomy ❖ There’s a high risk for fluid/electrolyte imbalance. Drink 2-3L per day. Can resume a regular, balanced diet gradually. Chew food thoroughly!

When taking prokinetics like metoclopramide teach to report abnormal, involuntary movements. QUESTIONS: Nurse explains to patients with gastroesophageal reflux disease (GERD) that this disorder --- ds Often involves relaxation of the lower esophageal sphincter, allowing stomach contents to back up into the esophagus. → the acidic components of the stomach touching the inside of the esophagus are responsible for “heartburn”, cardinal symptom of GERD. Client with GERD has chronic cough. This symptom may be indicative of ----Aspiration of gastric contents. Which of the following instructions should nurse include in teaching plan for GERD ? --- Do not lie down for 2 hours after eating Client encouraged to follow high-protein, low-fat diet, & avoid irritating foods.

Client understands administration when client will take drug at which time?--- at bedtime → taken at bedtime to inhibit nocturnal secretion of acid ❖ Clinical Judgment NG Tube to remove fluid and gas from the upper GI tract by the process known as decompression. QUESTION: After a subtotal gastrectomy, the NG tube drainage will be what color for about 12-24 hours after surgery? --- Dark brown → indicated digested blood; 6-12 hrs drainage would contain bright red blood A client has a NG tube following a subtotal gastrectomy. The nurse should --- Monitor for nausea, vomiting, & abdominal distention → will indicate gas & secretions are accumulating within gastric pouch due to impaired peristalsis or edema & drainage system not working properly ❖ Clinical Judgment: Nutrition QUESTION: ❖ A client with ulcerative colitis has persistent diarrhea. He is thin & lost 12 lbs since exacerbation of his ulcerative colitis. Which of the following will be most effective in helping meet his nutritional needs?--- Total Parenteral Nutrition (intravenously) (TPN) → Food will be withheld from clients with severe symptoms of ulcerative colitis, start TPN. ❖ Clinical Judgment: Enema Barium Enema: Barium inserted into rectum and colon. Must be scheduled prior upper GI studies Contraindications: bowel perforation or obstruction, inflammatory disease Monitor elimination of contrast material Client should report abdominal fullness, pain or delay of return of brown stool. ❖ Clinical Judgment: Diverticular Disease (diverticulosis) NPO, NG suctioning, IV fluids and antibiotics, analgesics Low fiber diet, slowly advance to high fiber when inflammation subsides Avoid indigestible material (nuts, seeds) and alcohol. Drink plenty of fluids Hematocrit and Hgb: decreased ESR: Increased WBC: Increased Stool for occult blood: Can be positive ❖ Clinical Judgment: Fecal Occult blood No vitamin C, red meat, chicken, fish, no NSAIDS, no uncooked veggies interpretation: 3 repeats of positive guaiac FOBT confirms GI Bleeding, Positive finding for blood is indicative of GI Bleeding ❖ Clinical Judgment: Barium Swallow instruct clients to use cathartics (i.e. bisacodyl) to evacuate the barium from the GI post procedure. Failure to eliminate barium places clients at risk for fecal impaction. ❖ Clinical Judgment: Pancreatitis severe, constant, knifelike pain in the left upper quadrant, midepigastric and/or radiates to the back.

ONLY CONTROLLED Two Primary Types: Primary open-angle glaucoma: ❖ Most common, Silent type, Loss of peripheral vision (tunnel vision), Malfunction of drainage system, Halos around lights, elevated IOP. Primary angle-closure glaucoma: ❖ Rapid onset of elevated IOP, ocular emergency, colored halos around lights, pupils nonreactive to light, pain/nausea, photophobia. Educate clients about disease processes and early identification of glaucoma such as reduced vision & mild eye pain. Tonometry- measures IOP (reference range 10-21) ○ IOP is usually higher in the mornings. Initial action is to CHECK THE TIME the test was performed. Atropine sulfate is contraindicated in clients with glaucoma because it increases IOP. Mydriatics contraindicated as well due to it increasing IOP. Anticholinergics contraindicated. Medication Teaching: prescribed eye meds every 12 hours. Instill 1 drop in each eye twice daily. Wait 5-10 min. Between each drop if more than one is prescribed to prevent dilution. Avoid touching the tip of the bottle to the eye. Wash hands before & after use. Once drop is instilled, apply pressure using punctal occlusion technique (pressure on inner eye). Emergency treatment for primary angle-closure glaucoma, quickly decreases IOP: IV Mannitol. Client education: wear sunglasses. Report signs of infection (yellow/green drainage), avoid activities that increase IOP (bending over wasit, sneezing, coughing, sex, head hyperflexion, tight clothing). Do NOT lie on the operative side. Report nausea & pain (possible hemorrhage). Report any lid swelling, decreased vision, bleeding or discharge, sharp sudden pain & flashes of light or floating shapes, signs of detachment. Best vision not expected until 4-6 weeks. Questions: 1. A client was recently diagnosed with open angle glaucoma. What client teaching should the nurse provide? a. Avoid cold medicines that contain pseudoephedrine (dilatory effect on pupils can increase IOP), laser surgery can correct flow to aqueous humor, expect impaired vision at night, driving may be dangerous due to loss of peripheral vision. 2. d/c teaching for open angle glaucoma and prescribed pilocar (miotics) eye drops? a. wait an hour before driving after taking medication 3. What do you give for open-angle glaucoma and decreased aqueous humor production? a. beta-blocker (timolol(timoptic)) ← first line therapy for glaucoma 4. What med is used as an emergency treatment for angle-closure glaucoma to quickly decrease IOP? a. IV Mannitol 5. A client with glaucoma is to receive 3 gtt of acetazolamide (Diamox) in the left eye. What should a nurse do? a. have client look up while administering drops 6. A client treated for chronic open-angle glaucoma (COAG) for 5 yrs asks “how does glaucoma damage my eyesight?”. The nurse's reply should be based on knowledge that COAG: a. causes increased IOP 7. Which of the following should the nurse provide as part of the information to prepare the client for tonometry? a. Painless procedure with no adverse effects 8. The nurse observes clients instill eye drops. The client says “I just try to hit the middle of my eyeball so drops don't run out of my eye.” nurse explains this method may cause: a. corneal injury 9. Patients with acute angle-closure glaucoma reports using the following med. Which indicated further instruction needed a. Diphenhydramine (benadryl) → may result in blindness if used in AACG, do not give atropine, benadryl or Vistaril (hydroxyzine)-- they are mydriatics. 10. Nurse is providing instructions on clients who will be self-admin eye drops. To minimize systemic absorption of drops, a nurse instructs the client to? a. Occlude nasolacrimal duct with a finger after instilling the drops. Fundamentals EYE assessment: Test used to screen for presbyopia (impaired near vision or farsightedness): Rosenbaum eye chart. Ishihara test assess for: Color vision Vision loss risk factors: Age is the most significant Eye infection, inflammation or injury Brain tumor Client education: Quit smoking Limit alcohol intake Keep BP, blood glucose and cholesterol under control Eat foods rich in antioxidants, such as green leafy vegetables. Presbyopia: age-related loss of the eye’s ability to focus on close objects due to decreased elasticity of the lens. Cataracts: opacity of the lens, which blocks the entry of light rays into the eye. Glaucoma: Structural damage within the eye resulting from elevated pressure within the eye leading to blindness. Diabetic retinopathy: Noninflammatory changes in the eye’s blood vessels leading to blindness. Macular degeneration: Loss of central vision from deterioration of the center of the retina.
