Week 5 Concepts: Nutrition Acid-Controlling Drugs Prepare: Acid-Controlling Drugs Stomach Areas Identify the areas of the stomach. 0114071 Gastric Glands Produce and secrete hydrochloric acid Parietal cells Secrete pepsinogen which is a precursor to pepsin Chief cells Provide a protective coating for the stomach Mucosa cells Match the gastric gland cell with its function. Parietal Cells Which receptors in the stomach are responsible for stimulating the secretion of acid from the parietal cells? Select all that apply. Histamine Adenosine triphosphate (ATP) pump Proton ion Gastrin Acetylcholine (ACh) Self-Check: Stomach Acid Gastric Hyperacidity Gastric hyperacidity is the over production of stomach acid. Stomach Acid The pH of stomach acid is 1-4. Self-Check: Hyperacidity Gastroesophageal Reflux Disease (GERD) Gastroesophageal reflux disease is when excessive acid backs up into the esophagus. Acid-controlling Drugs Antacids Reduce acid by neutralization within the stomach Histamine (H) 2 Blockers (H2 receptor agonist) Reduce acid by blocking signals to the parietal cells Match the acid-controlling drugs with how they work. Proton Pump Inhibitors Reduce acid by working within the parietal cells Self-Check: H. Pylori (Helicobacter pylori) Helicobacter pylori (H. pylori) Helicobacter pylori (H. pylori) is a Bacteria that can infect the gastric track. Reflect: Acid-Controlling Drugs Acid-controlling Drugs The telehealth nurse is responding to question send to the Hancock Healthcare Services’ social media page. Review the questions and choose the best response. Question 1 / 6 Mandy345 asks: I have heartburn and I am in the pharmacy. Do all acid controlling drugs work the same way? Choose your best response from the choices given below. “Acid controlling drugs do not all work the same way.” “It depends on each person’s genetics.” “Yes, they do.” “I think so.” Question 2 / 6 MrTom2u wrote: I take a lot of prescribed daily medication, including digoxin. Is it safe to take any type of acid controlling drugs with my medications? Choose your best response from the choices given below. “Yes, acid controlling drugs are safe. You may also need to take an extra dose of your digoxin to stay in your therapeutic range.” “Yes, acid controlling drugs are safe and should be taken with your nightly medications.“ “Yes, acid controlling drugs are safe and can be taken with your daily medications.” “Yes, acid controlling drugs are generally safe. Check with your doctor for the best choice of acid controlling drugs for you.” Question 3 / 6 Mavis52 wrote: What lifestyle changes can I start that will prevent/reduce my heartburn (hyperacidity) symptoms? Choose the correct response from the choices given below. “Chewing gum will prevent your hyperacidity symptoms.” “Eat later in the evening so your stomach can digest your food while you sleep.” “Drinking more water will prevent your hyperacidity symptoms.” “Changing your diet and reducing stress can decease your symptoms.” Question 4 / 6 Mavis52 wrote back: My husband said that smelling his food on the grill will make my stomach secrete digestive fluid. Is this true? Choose the correct response from the choices given below. “No, food must be present in the stomach for the secretion of digestive enzymes.” “Yes. Smelling, seeing, or tasting food can cause your stomach to secrete digestive acids.” “Yes, but it only happens with smelling grilled food.” “No, only chewing and swallowing food makes you secrete stomach acids.” Question 5 / 6 Mav12 asks: Do these work the same way to reduce acid in my stomach? Acid-reducing medication Effervescent tablet antacid Choose your best response from the choices given below. “Yes, they both neutralize the acid present in the stomach.” “Yes, they work the same in your stomach; they just have different names.” “No, the effervescent tablet antacid neutralizes the acid in the stomach and the acid-reducing medication blocks signals to cells in your stomach.” “No, the acid-reducing medication neutralizes the acid in the stomach and the effervescent tablet antacid blocks signals to cells in your stomach.” Question 6 / 6 You just received a direct message (DM) from Twitter. Mary10 wrote: @HHSH My Dad was just admitted to the intensive care unit. Why was he given an acid-controlling drug? He is intubated and not eating. Choose the best response from the choices given below. “Sorry to hear about your dad. This is old school care and is outdated and not needed.” “Sorry to hear about your dad. This is not a normal course of treatment.” “Sorry to hear about your dad. It was most likely given to prevent stress related ulcers.” “Sorry to hear about your dad. It was most likely given to shrink his stomach.” Parietal Cells The secondary response of parietal cells activates the hydrogen–potassium–adenosine triphosphatase (ATP) pump. Antacids (magnesium carbonate, aluminum hydroxide, calcium carbonate, sodium bicarbonate) Prepare: Antacids Antacid Which salt compounds are contained in antacid? (Select all that apply.) Manganese Sodium Chloride Magnesium Aluminum Calcium Simethicone What is the purpose of simethicone? Reduce gas Dilate stomach vessels Reduce gastric motility Promote defecation Side Effect of Antacids Antacids are made of salt compounds. Magnesium antacid salt compound can cause the side effect of diarrhea. Self-Check: Antacids Therapeutic Effects of Antacids What are the expected therapeutic effects of antacids? Select all that apply. Raise stomach pH Lower stomach pH Allow ulcers time to heal Neutralize stomach acids Provide relief from heartburn Treat patients with heart disease Self-Check: Drug Interactions Reduces the ability of the other drug to be absorbed into the body Adsorption Chemical inactivation of other drugs that produces insoluble complexes Chelation Increases the absorption of basic drugs and decreases the absorption of acidic drugs Increased stomach pH Increases the excretion of acidic drugs and decreases the excretion of basic drug Increased urinary pH Match the interaction with the definitions. Self-Check: Antacid Compounds Combining two salt compounds in an antacid has what beneficial effect? Increase absorption of the antacid Decrease the antacid efficacy Prevent side effects from each salt compounds. Prevent metabolic acidosis Antacid Side Effects Salt Compound Side effects Magnesium-Containing Antacids Carbonate salt Diarrhea Aluminum-Containing Antacids Carbonate salt Constipation Calcium-Containing Antacids Carbonate salt Constipation/Diarrhea Sodium-Containing Antacids Bicarbonate salt Flatulence, gastric distention Drag the correct side effect for each of the antacid salt compounds given below: Reflect: Antacids Side Effects A client takes an aluminum-containing antacid, such as aluminum hydroxide, for which side effect? Diarrhea Fluid retention Constipation Gastrointestinal (GI) upset Antacid Drug Mike has chronic renal failure. Magnesium-containing antacids may not be the best based on the patient's medical condition. Antacid Table Complete the table below by dragging the appropriate choices into the blank cells. Mechanism of Action Antacids are effective in the treatment of hyperacidity based on which mechanism of action? Decreases duodenal pH Decreases gastric pH Decreases stomach motility Neutralizes gastric acid Administration of Antacids Antacids should not be taken 1 hour before or 2 hours after any prescription medications. Antacids A client called asking about antacids. The client asked,
