GI MEDS AND PLAN OF CARE
PLAN FOR THE DAY:
• Quick Notes Review
• Case Study
• NCLEX Questions
GASTRIC ACID
System
• Esophagus
• Stomach
• Liver/gallbladder
• Pancreas
• Small/large intestine
Gastric acid production
• Parietal cells- H+ production
• Receptors- histamine2
Function
• Stomach pH 1-4
• Digestion
• Defense against infection
WHAT DO WE DO WITH THE
OVERPRODUCTION OF THIS ACID????
****Give antacids= to neutralize!
•
Milk of Magnesia (magnesium
hydroxide)
• TUMS (calcium carbonate)
Heartburn, gastritis, peptic ulcer
disease (PUD)
****Suppress gastric acid!
H2 receptor blockers- bind to H2
receptor
• Pepcid (famotidine)
• Decrease HCl acid production
• Decrease heartburn
GERD, erosive esophagitis, PUD,
H. pylori, gastritis, prevent stress
ulcers
WHAT DO WE DO WITH THE OVERPRODUCTION
OF THIS ACID????
****Suppress gastric acid!
Proton pump inhibitors (PPI)blocks proton pump, stops HCl
production
• Prevacid (lansoprazole)
• Prilosec (omeprazole)
• Protonix (pantoprazole)
Decrease HCl production, decrease
heartburn
• Caution with hepatic disease!!!!
Gastric barrier- adheres to
gastric mucosa/ binds to ulcer
• Carafate (sucralfate)
Decrease heartburn

GASTROINTESTINAL CASE STUDY
History of present illness (HPI):
Mr. D- 70 year old male- enters your clinic with a complaint of
severe upper abdominal pain that occurs mostly in the evening
hours. It is relieved by food, although he vomits his meals several
times each week. Wife states intermittent confusion in last month.
Past medical history (PMH):
 He has a history of peptic ulcers and alcohol abuse
 Smoking has been reduced to two packs per week
 He is taking no drugs, other than Rolaids for his indigestion

RESPIRATORY MEDS AND PLAN
OF CARE
PLAN FOR THE DAY:
• Respiratory Review (A&P/ Structures)
• Mediators of inflammation
• Respiratory defense mechanisms
• Homework Review
RESPIRATORY MEDS AND PLAN
OF CARE
RESPIRATORY MEDS AND PLAN OF
CARE
The respiratory system has built-in methods to prevent
harmful substances from entering the lungs:
•Your nose moistens and warms the air.
•The hair (cilia) in your nose helps filter out large particles.
•Mucus produced by cells in the trachea and bronchial tubes
keeps air passages moist and aids in trapping dust, bacteria,
and other substances.
•Cilia in the air passages move in a sweeping motion
upwards towards the throat and mouth to get the mucus
and bacteria etc out of the lungs.
RESPIRATORY MEDS AND PLAN OF
CARE
Mediators of inflammation
1. Bradykinin, complement, prostaglandin.
2. Leukotrienes.
3. Histamine.
4. Mast cells.
Respiratory defense mechanisms
1.
Cough.
2. Reflex bronchoconstriction.
3. Filtration, mucociliary response.
4. Alveolar macrophages -Macrophages engulf and digest
foreign materials in a process known as phagocytosis.
RESPIRATORY MEDS AND PLAN OF
CARE
Asthma- caused by inflammation in the airways, causes the airways of the
lungs to swell and narrow, leading to wheezing, shortness of breath, chest
tightness, and coughing.
Chronic obstructive pulmonary disease (COPD)Chronic obstructive airways disease; Chronic obstructive lung disease; Chronic
bronchitis; Emphysema; Bronchitis – chronic
• Chronic bronchitis- which involves a long-term cough with mucus
• Emphysema- which involves destruction of the lungs over time
Pneumonia- an inflammation of the lungs caused by an infection
RESPIRATORY MEDS AND PLAN OF
CARE
• Drugs affecting the respiratory system
• Bronchodilators
• Adrenergic agonists• Proventil (albuterol)- short acting
• Xopenex (levalbuterol)- short acting
• Serevent (salmeterol)- long acting
• Leukotriene inhibitors
• Anticholinergics
• Decrease Inflammation
• Glucocorticoid steroids
• Antihistamines
• Decrease secretions
MEDICATIONS FOR THE
INTEGUMENTARY SYSTEM
• Burns- see handout
• Eczema- corticoidsteroid creams
• Psoriasis• corticoidsteroid creams,
• topical retinoids (Tazarotene),
• Vit D analogues (Dovonex)
