small frequent meals, bland, high protein, low fat, no stimulants (caffeine)
Assessment Q's to ask patient with Renal calculi???
-Are you urinating more frequent than usual? Does it burn or sting?? do you have a feeling that your unable to hold urine in?? -family hx (3 generations, cystine stones are autosomal recessive) -prescribed/OTC meds= NSAIDs can be nephrotoxic, antibiotics.. -dietary supplements -hyperparathyroidism, increased ca in urine, treated with Vit D or surgical removal of parathyroid gland)
What precautions are important for the arm on the surgery immediately post-op and after discharge to home for mastectomy???
-BP readings, venipuncture, and injections should not be done on affected arm -elastic bandages should not be used in early post-op period -instruct pt. to protect arm from even minor trauma (sunburn, pinprick) -advise surgeon of all trauma and observe site for inflammation -make sure pt. understands that there will always be a risk for lymphedema
Patient Teaching for GERD
-NO smoking (decreases acid clearance from LES) -avoid certain foods that can cause aggravation (peppermint, tea, coffee, chocolate, fatty foods, milk) -avoid late night snacking-no eating 3 hours before bedtime -take fluid between meals -decrease weight if needed -avoid wearing tight clothing around the waist.
laprascopic cholecystectomy POST-OP
-TCDB q 2 hrs -PREVENT pneumothorax/atelectasis- listen to lungs, O2 sat, DB and ambulation!!!! Prevent DVT -Lie patient in sim's position (on left side, flexed knees) -Common complaint is referred pain to shoulder due to CO2 used to inflate abd cavity in surgery -Assess incision site for redness, drainage (pus), presence of bile from T-tube. -May have increased bleeding, check PT coagulation -Teach patient to monitor bowel habits, eat high fiber, drink plenty of fluids, take other meds 1 hr before eating or 4-6 hr after

Key assessment for BPH-objective
-patient has enlarged prostate on DRE, the patient will bend over table or lie on side for exam -Lab tests= creatinine to rule out renal insufficiency, urinalysis, PSA -residual urine > 100 mL (bladder scan) or measure urine flow with uroflowmetry
Nissen Fundoplication POST-OP CARE

POST OP complications that can occur with hysterectomy??
1. DVT due to lithotomy position in surgery- TEDs, SCD, Lovenox, leg exercises, ambulation. Avoid high-fowler's/pressure under the knees to minimize stasis and pooling of blood 2. Pulmonary embolism- s/s are chest pain, dyspnea tachycardia, report STAT 3. Urinary retention r/t loss of bladder tone. Check for residual urine (bladder scanner) Kegel exercises, encourage fluids when allowed post-op 4. Paralytic ileus- check bowel sounds, keep pt. NPO until they return and there is no nausea or distention. Sometimes rectal tube is used to relieve gas. encourage ambulation 5. disturbed body image r/t perceived loss of femininity and ability to conceive
PUD therapy?
1. GERD Meds.. antacids, PPI, H2 receptor blockers, anticholinergics Antibiotics (flagyl, tetracycline, amoxicillin) Anticholinergics, cytoprotective therapy Tricyclic pain relief
Possible complications of PUD

common lab tests to evaluate urinary function??
BUN, creatinine, urinalysis
Normal level of BUN and creatinine, how do these tests rt anything that we have studied
BUN- 7 to 20 Creatinine- 0.6 to 1.4 **An increase in these show that BPH would be affecting the kidney function
BUN serum Creatinine urinary creatinine Specific Gravity
BUN= 7-20 serum Creatinine= 0.6-1.4 Urinary creatinine= 85-135 reflects GFR Specific Gravity= 1.002-1.030 substances in urine if levels are high (glucose, protein, bilirubin, WBC, RBC, crystals, bacteria)
Manifestations of patient with lithiasis??
Back pain Renal colic (smooth muscle contraction of ureters, referred pain to groin/testicles, comes in waves) Hematuria (due to stone rubbing on the lining **pain moves to lower quadrant as stone nears UVJ
Which information will the nurse include for a patient with newly diagnosed gastroesophageal reflux disease (GERD)? a. "Peppermint tea may reduce your symptoms." b. "Keep the head of your bed elevated on blocks." c. "You should avoid eating between meals to reduce acid secretion." d. "Vigorous physical activities may increase the incidence of reflux."
ANS: B Elevating the head of the bed will reduce the incidence of reflux while the patient is sleeping. Peppermint will decrease lower esophageal sphincter (LES) pressure and increase the chance for reflux. Small, frequent meals are recommended to avoid abdominal distention. There is no need to make changes in physical activities because of GERD.
An older patient with a bleeding duodenal ulcer has a nasogastric (NG) tube in place. The health care provider prescribes 30 mL of aluminum hydroxide/magnesium hydroxide (Maalox) to be instilled through the tube every hour. To evaluate the effectiveness of this treatment, the nurse a. monitors arterial blood gas values daily. b. periodically aspirates and tests gastric pH. c. checks each stool for the presence of occult blood. d. measures the volume of residual stomach contents.
ANS: B The purpose for antacids is to increase gastric pH. Checking gastric pH is the most direct way of evaluating the effectiveness of the medication. Arterial blood gases may change slightly, but this does not directly reflect the effect of antacids on gastric pH. Because the patient has upper gastrointestinal bleeding, occult blood in the stools will appear even after the acute bleeding has stopped. The amount of residual stomach contents is not a reflection of resolution of bleeding or of gastric pH.
6. A patient who has gastroesophageal reflux disease (GERD) is experiencing increasing discomfort. Which patient statement to the nurse indicates that additional teaching about GERD is needed? a. "I take antacids between meals and at bedtime each night." b. "I sleep with the head of the bed elevated on 4-inch blocks." c. "I eat small meals during the day and have a bedtime snack." d. "I quit smoking several years ago, but I still chew a lot of gum."
ANS: C GERD is exacerbated by eating late at night, and the nurse should plan to teach the patient to avoid eating at bedtime. The other patient actions are appropriate to control symptoms of GERD.
Which patient choice for a snack 3 hours before bedtime indicates that the nurse's teaching about gastroesophageal reflux disease (GERD) has been effective? a. Chocolate pudding c. Cherry gelatin with fruit b. Glass of low-fat milk d. Peanut butter and jelly sandwich
ANS: C Gelatin and fruit are low fat and will not decrease lower esophageal sphincter (LES) pressure. Foods such as chocolate are avoided because they lower LES pressure. Milk products increase gastric acid secretion. High-fat foods such as peanut butter decrease both gastric emptying and LES pressure.
10. The nurse will anticipate teaching a patient experiencing frequent heartburn about a. a barium swallow. b. radionuclide tests. c. endoscopy procedures. d. proton pump inhibitors.
ANS: D Because diagnostic testing for heartburn that is probably caused by gastroesophageal reflux disease (GERD) is expensive and uncomfortable, proton pump inhibitors are frequently used for a short period as the first step in the diagnosis of GERD. The other tests may be used but are not usually the first step in diagnosis.
An 80-yr-old patient who is hospitalized with peptic ulcer disease develops new-onset auditory hallucinations. Which prescribed medication will the nurse discuss with the health care provider before administration? a. Sucralfate (Carafate) b. Aluminum hydroxide c. Omeprazole (Prilosec) d. Metoclopramide (Reglan)
ANS: D Metoclopramide can cause central nervous system side effects ranging from anxiety to hallucinations. Hallucinations are not a side effect of proton pump inhibitors, mucosal protectants, or antacids.
8. The nurse explaining esomeprazole (Nexium) to a patient with recurring heartburn describes that the medication a. reduces gastroesophageal reflux by increasing the rate of gastric emptying. b. neutralizes stomach acid and provides relief of symptoms in a few minutes. c. coats and protects the lining of the stomach and esophagus from gastric acid. d. treats gastroesophageal reflux disease by decreasing stomach acid production.
ANS: D The proton pump inhibitors decrease the rate of gastric acid secretion. Promotility drugs such as metoclopramide (Reglan) increase the rate of gastric emptying. Cryoprotective medications such as sucralfate (Carafate) protect the stomach. Antacids neutralize stomach acid and work rapidly.

After a transurethral resection of the prostate (TURP), a 64-year-old patient with continuous bladder irrigation complains of painful bladder spasms. The nurse observes clots in the urine. Which action should the nurse take? a. increase the flow rate of the bladder irrigation b. administer the prescribed IV morphine sulfate c. give the patient the prescribed belladonna and opium suppository d. manually instill and then withdraw 50 mL of saline into the catheter
D.
Complications of Bilroth I/II
