A patient with PUD asks the nurse why it's important to avoid NSAIDs. The nurse's best response is:

Correct Answer: B

Rationale: The correct answer is B because NSAIDs inhibit prostaglandin synthesis, reducing blood flow to the stomach lining, which can lead to ulcer formation. This is important for a patient with PUD as it can exacerbate their condition. Choice A is incorrect as NSAIDs do not cause fluid retention in PUD. Choice C is incorrect as NSAIDs actually decrease mucus production, making the stomach lining more vulnerable. Choice D is incorrect as NSAIDs are more likely to cause gastrointestinal issues like ulcers rather than constipation.

Correct Answer: B

Rationale: Correct Answer: B - The medications work together to reduce acid and eliminate the infection. Rationale: 1. Antibiotics target and eliminate H. pylori infection, a leading cause of PUD. 2. Proton pump inhibitors reduce gastric acid production, aiding in ulcer healing. 3. Combining antibiotics and PPIs effectively treats both infection and acid production. 4. This comprehensive approach helps resolve the underlying causes of PUD efficiently. Incorrect Choices: A: Each medication targets a different cause of your ulcer. - Not accurate as antibiotics and PPIs target infection and acid production. C: One medication reduces acid, and the others help your stomach heal. - Oversimplifies the treatment process. D: The combination ensures that your symptoms will be controlled quickly. - Focuses on symptom management rather than addressing the root causes.

Correct Answer: A

Rationale: The correct answer is A because avoiding spicy foods and caffeinated beverages helps reduce irritation to the stomach lining in chronic gastritis. Spicy foods can exacerbate inflammation, while caffeine can increase stomach acid production. These dietary modifications are essential for managing symptoms. Option B is incorrect because alcohol can irritate the stomach lining and worsen gastritis. Option C is incorrect as increasing dairy intake may not be necessary and could potentially aggravate symptoms in some individuals. Option D is incorrect as eating small, frequent meals is actually recommended for managing chronic gastritis to prevent excessive stomach acid production.

Correct Answer: A

Rationale: The correct answer is A: Bromocriptine. Bromocriptine is a dopamine agonist used in Parkinson's disease treatment. Drug overdosage can lead to pronounced gastrointestinal side-effects due to its action on dopamine receptors in the gastrointestinal tract. Co-beneldopa (B) is a combination drug of levodopa and carbidopa, primarily affecting the central nervous system, not causing significant gastrointestinal issues. Amantadine (C) is an antiviral and anti-Parkinson agent with minimal gastrointestinal side effects. Selegeline (D) is a monoamine oxidase-B inhibitor, typically causing side effects like insomnia and dizziness rather than pronounced gastrointestinal issues.

Correct Answer: C

Rationale: The correct answer is C: A-large, B-amino acids, C-simple sugars. Rationale: 1. Organic compounds like proteins and starches are too large to diffuse into cells, which is why the word "large" fits in blank A. 2. Proteins are digested into amino acids, so "amino acids" is the appropriate choice for blank B. 3. Starches are digested into simple sugars, making "simple sugars" the correct word for blank C. Summary: - Option A is incorrect because proteins are digested into amino acids, not simple sugars. - Option B is incorrect because it does not account for the specific digestion products of proteins and starches. - Option D is incorrect because starches are digested into simple sugars, not amino acids.
