A client who has chronic bronchial asthma has had a mast cell stabilizer prescribed.
What drug would the provider prescribe?
Isoetharine.
Aminophylline.
Ipratropium.
Cromolyn.
The Correct Answer is D
Choice A. Isoetharine is a bronchodilator that works by relaxing muscles in the airways to improve breathing. It is not a mast cell stabilizer.
Choice B is wrong because aminophylline is a bronchodilator that relaxes the muscles in the airways and is used in the treatment of asthma and chronic obstructive pulmonary disease (COPD). It is not a mast cell stabilizer.
Choice C is wrong because Ipratropium is an anticholinergic bronchodilator that helps to open up the airways in the lungs. It is used in the treatment of COPD and sometimes asthma, but it is not a mast cell stabilizer.
Choice D. Cromolyn is a mast cell stabilizer that helps prevent the release of substances in the body that cause inflammation and asthma symptoms. It is used for the prevention of asthma attacks and is particularly effective in managing exercise-induced asthma and allergic asthma triggers.

Correct Answer is B
Explanation
This is because a nutritious diet provides adequate fiber and nutrients for the GI tract, avoiding alcohol prevents dehydration and irritation of the GI mucosa, and cautious use of laxatives prevents dependency and electrolyte imbalance.
Choice A is wrong because caffeine can stimulate the GI motility and cause diarrhea or cramps.
Choice C is wrong because some prescription medications can affect the GI function, such as antibiotics, opioids, or antacids.
Increased fluid intake is good, but not enough to promote optimal GI function.
Vigorous exercise can also cause GI distress or dehydration.
Choice D is wrong because adequate fluid intake is essential for preventing constipation and maintaining hydration.
Exercise can also help with bowel movements and overall health.
Normal ranges for GI function vary depending on the individual, but generally, a person should have at least one bowel movement every 3 days and no more than 3 bowel movements per day.
The stool should be soft, formed, and easy to pass.
Correct Answer is A
Explanation
This is because proton pump inhibitors (PPIs) are drugs that block the enzyme that produces hydrochloric acid in the stomach, thereby reducing the amount of acid secreted into the lumen. PPIs are commonly used to treat peptic ulcer disease and gastroesophageal reflux disease.
Choice B. Histamine-2 antagonist is wrong because histamine-2 antagonists (H blockers) are drugs that block the action of histamine on the parietal cells of the stomach, thereby reducing the amount of acid secreted into the lumen.
However, PPIs are more potent and effective than H blockers in suppressing acid secretion.
Choice C. Prostaglandin is wrong because prostaglandins are substances that protect the stomach lining from the damaging effects of acid and other factors.
Prostaglandins do not directly affect the secretion of acid into the lumen, but they may increase the production of mucus and bicarbonate that buffer the acid.
Choice D. Antipeptic agent is wrong because antipeptic agents are drugs that form a protective barrier over the ulcer crater, preventing further damage from acid and pepsin.
Antipeptic agents do not affect the secretion of acid into the lumen, but they may enhance healing by creating a favorable environment for tissue repair.
Normal ranges for hydrochloric acid secretion in the stomach are 1.5 to 3.5 liters per day, with a pH of 1.5 to 3.53.
