Pepcid is an H2 blocker (blocks histamine; histamine stimulates acid production) Give it before eating, give in the morning
Omeprozole is a PPI (decreases the amount of acid produced): Give before eating
Antacids (neutralize acid): give after eating

Q

Hiatal Hernia

A

Results from a defect in the diaphragm at the point where the esophagus passes through it (Sliding Hiatal Hernia: part of the stomach goes up through the established hole in the diaphragm. Paraesophageal Hiatal Hernia: hernia in diaphragm over from the esophageal opening and some stomach gets trapped); common in women; Cause: congenital muscle weakness or weakness resulting from trauma; Causes: multiparaty, obesity, age-related loss of muscle tone, smoking

Q

Peptic Ulcer

A

Circumscribed loss of tissue in an area of the GI tract that is in contact with hydrochloric acid and pepsin; most occur in duodenum (can also occur anywhere from the esophagus to the duodenum (including the jejunum if gastric bypass surgery)); can turm malignant; Cause: H. pylori, chronic NSAID use, smoking, physiologic stress; S/S: pain dec when full/inc when empty, burning localized pain, bleeding, unexplained wt loss

Q

Tx for hemmorhage from ulcer

A

Complete rest for the GI tract, blood transfusions, gastric lavage with saline solution, IV fluids.

18
Q

Serotonin antagonists and Dopamine antagonists

A

Serotonin antagonist: -setron (ie Ondansetron)

Dopamine antagonist

19
Q

Why doesn’t Eileen like dopamine antagonists?

A

(makes them weird and loopy) Messes with them, extra pyramidal effects.

20
Q

Metabolic problem if they vomit a lot?

A

Alkalosis (they may have started with acidosis but all the vomiting has pushed them to alkalosis)

21
Q

Chemo: to prevent them from vomiting

A

Give zofran 1 hour before chemo

22
Q

Vomiting Patients

A

Precautions. Assess them. Condition you want to worry about before giving them pills? ARE THEY PREGNANT

23
Q

Know the difference between diverticulosis and diverticulitis

A

Diverticula-the sacs
Diverticulosis-disease where you have diverticula in the intestine
Diverticulitis-Inflammation of the diverticula

24
Q

Cirrhosis, know the basics and how you get it

A

Alcohol consumption
Hepatitis
Drug use

25
Q

Ascites - how do you take care of them

A

Weigh them
Measure the belly
Protein isn’t metabolized properly
If the ammonia level is down, give them protein to eat
If the ammonia level is up, decrease their protein intake
Low albumin levels
Signs and symptoms of low albumin levels: Edema in their belly, especially ascite
Give them chicken. All the protein they need is right there. Rice and beans would require a large consumption

26
Q

Ammonia in your body

A

too much.. You start getting wacky it’s called Hepatic Encephalopathy
Given them lactulose for treatment
What does lactulose do? It binds the ammonia and the person poops it out

27
Q

Know how to take care of someone with a total hip replacement

A

No rotation
No sitting straight up
Pillow between the knees
Lay them on the unaffected side

28
Q

Amputations. Why do people get them

A

Trauma
Diabetes
Cancer
Long-standing infections of bone and tissue that prohibit restoration of Fx
Thermal injuries
Deformity of limb
Life-threatening disorders (ie arterial thrombosis or gas bacillus infections)

29
Q

Phantom pain

A

The brain perceives that the limb is still there and causing pain because the nerves still work that go to the stump. If severe: nerve endings may be removed at end of the stump.

30
Q

Post knee amputation care

A

Reduce pain and anxiety; support patient as they begin to grieve the loss of the limb and adapt to potential changes; admin narcotics; assist in ADLs; promote adequate sleep; discuss coping techniques; be understanding

31
Q

Common bile duct is connected to the pancreas, gallbladder and the liver. What can cause an obstruction?

A

A stone

32
Q

Gallbladder attack

A

Foods to eat during an attack? Low fat diet; RUQ pain

33
Q

What is the daily requirement for calcium with supplements and/or food?

A

1000 mg

34
Q

Rheumatoid Arthritis

A

Autoimmune, systemic inflammatory disorder of connective tissue/joints characterizes by chronicity, remissions, and exacerbations; great potential for disability; other body systems may be affected (ie eyes, skin, heart, lungs, kidney, blood vessels); can cause malaise and fever; majority affected are women; onset typically middle-age (can occur at any age); rxn from RA occurs primarily in the synovial tissue; Tx: NSAIDs, steroids, immunosuppressents

35
Q

Osteoarthritis

A

aka Degenerative Joint Disease (DJD); most common form of arthritis; “wear and tear” disease and typically affects wt-bearing joints (ie knees, hips, spine, hands); no remissions or systemic symptoms; primary: no known etiology; secondary: known underlying cause such as injury, obesity, inactivity, congenital disorder; starts with cartilage breakdown, leading to bone spurs (growth of bone in places where the cartilage has broken down); pain and limited joint mobility; deformity of the joint; possible slight dislocation of the join; self-Tx for pain: NSAIDs and PPIs. Prob: PPIs can reduce bone density

36
Q

Gout

A

hyperuricemia (accumulation of uric acid in the blood) caused by alterations in uric acid production, excretion, or both. Primary: severe dieting or starvation, excessive ingestion of purines, heredity; Secondary: abnormal purine metabolism, inc rate of protein synthesis with overproduction or underexcretion of uric acid, inc cellular turnover (as in leukemia, mult myeloma, and other cancers, some anemias, psoriasis), dec excretion of uric acid r/t diuretics, salicylates or excessive R-OH intake esp beer; S/S acute paint and tenderness in one joint, skin redness, swelling of joint, common in Hallux, attack may last 1-2 weeks

37
Q

Osteoporosis

A

A loss of bone density, occurs principally in older adults: more women than men; bone loss exceeds bone creation-overtime leads to total bone density reduction, porous/brittle/fragile bones; causes: dec PTH/estrogen/Calcitonin (promotes bone formation) levels, family Hx, tobacco use, chromic low calcium intake, excessive caffeine intake, prolonged use of corticsteroids, hyperthyroidism, hyperparathyroidism, Cushing’s syndrome, malabsorption syndromes, breast cancer, renal/liver failure, vit D deficiency, some meds (inc heparin and SSRIs)

38
Q

Hepatitis

A

A/E from food or water

B/C/D from blood/body fluids

39
Q

Asses patient for appendicitis

A

Blood tests - CBC, CMP or BMP, amylase, lipase
NPO prior to surgery
No enemas
RLQ pain

40
Q

Osteomyelitis

A

Infection of the bone, resulting in limited blood supply to the bone, inflammation of and pressure on the tissue, bone necrosis, and formation of new bone around devitalized bone tissue; diff to treat; most common: S. aureus infection; acute: injury that leads to infection; vasc insufficiency in diabetes; pin sites of skeletal traction; long-term dialysis/chemo/corticosteroid Tx/immunosuppressant meds inc risk; weakened bone prone to pathologic fracture; septicemia risk
