A client with peptic ulcer disease is experiencing fewer symptoms because of the suppression of hydrochloric acid secretion into the lumen of the stomach.
What category of medication is this client most likely receiving?
Proton pump inhibitor.
Histamine-2 antagonist.
Prostaglandin.
Antipeptic agent.
The Correct Answer is A
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.

Correct Answer is D
Explanation
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 becauseIpratropium 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 A
Explanation
This is because levothyroxine can increase the anticoagulant effect of oral anticoagulants and increase the risk of bleeding. The nurse should check the client’s prothrombin time and international normalized ratio (INR) regularly and report any abnormal values to the prescriber.
Choice B is wrong because hypothyroidism does not increase the risk of infection.
Choice C is wrong because hypothyroidism does not affect the level of consciousness unless it is severe and causes myxedema coma.
Choice D is wrong because hypothyroidism does not cause electrolyte imbalances.
Normal ranges for prothrombin time are 11 to 13.5 seconds and for INR are 0.8 to 1.22.
