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 C
Explanation
Dronabinol is a synthetic cannabinoid that can cause psychoactive effects such as euphoria, anxiety, hallucinations, and paranoia. The nurse should monitor the client’s mental status after administering the drug and report any changes or adverse reactions.
Choice A is wrong because dronabinol does not affect the heart rate significantly.
Choice B is wrong because dronabinol may lower or raise the blood pressure depending on the dose and the individual response, but this is not a priority assessment.
Choice D is wrong because dronabinol does not affect the skin integrity directly.
Correct Answer is A
Explanation
This is because phenothiazines are contraindicated in patients with suspected or established subcortical brain damage. Phenothiazines can cause central nervous system effects such as drowsiness, dizziness, and extrapyramidal symptoms that may worsen the condition of a client with a brain injury.
Choice B is wrong because phenothiazines are not contraindicated in clients with ischemic heart disease.
However, they should be used with caution as they can cause hypotension and cardiac arrhythmias.
Choice C is wrong because phenothiazines are not contraindicated in pediatric clients.
However, they should be used with caution as they can cause sedation, anticholinergic effects, and paradoxical excitement.
Choice D is wrong because phenothiazines are not contraindicated in clients with type 2 diabetes.
However, they should be used with caution as they can cause hyperglycemia and alter the effects of antidiabetic drugs.
