1. Which of the following statements about Helicobacter pylori (H. pylori) is false?

• A. H. pylori does not invade the gastric or duodenal epithelium
• B. H. pylori stimulates gastric acid secretion
• C. Eradication of H. pylori prevents adenocarcinoma of the stomach
• D. H. pylori produces a urease that splits urea into ammonia and CO2

Correct answer: C

Rationale: H. pylori is known to reside in the mucus layer of the stomach and does not invade the epithelium. It produces urease that splits urea into ammonia and CO2. This action helps in neutralizing the acidic environment and allows H. pylori to survive. Additionally, urease activity can be detected in diagnostic tests for H. pylori. The stimulation of gastric acid secretion and disruption of the protective mucus layer are mechanisms by which H. pylori promotes injury. While eradicating H. pylori infection has been associated with a decreased risk of developing gastric cancer, it does not prevent adenocarcinoma of the stomach entirely.

2. A patient with schizophrenia is prescribed olanzapine. What is an important side effect for the healthcare provider to monitor?

• A. Hypertension
• B. Weight gain
• C. Hypoglycemia
• D. Bradycardia

Correct answer: B

Rationale: The correct answer is B: Weight gain. Olanzapine, an atypical antipsychotic, is known to cause significant weight gain and metabolic syndrome. It is crucial for healthcare providers to closely monitor patients for these side effects to prevent complications and provide appropriate interventions.

3. A 65-year-old woman presents with difficulty swallowing, weight loss, and a history of long-standing heartburn. She has been on proton-pump inhibitors for years, but her symptoms have worsened. What is the most likely diagnosis?

• A. Peptic stricture
• B. Esophageal cancer
• C. Achalasia
• D. Esophageal spasm

Correct answer: B

Rationale: The presentation of difficulty swallowing, weight loss, and worsening symptoms despite long-term use of proton-pump inhibitors raises suspicion for esophageal cancer, especially in a patient with a history of chronic heartburn. Esophageal cancer should be considered in this scenario due to the concerning symptoms and lack of improvement despite appropriate medical management.

4. A client is being treated with an antidepressant for major depressive disorder. Which statement by the client indicates a need for further teaching?

• A. I know it may take several weeks before I start feeling better.
• B. I should avoid drinking alcohol while taking this medication.
• C. I will stop taking the medication as soon as I feel better.
• D. I should take the medication at the same time every day.

Correct answer: C

Rationale: Choice C indicates a need for further teaching because stopping antidepressants abruptly can lead to withdrawal symptoms. It is essential for the client to follow the healthcare provider's instructions and complete the full course of medication even if they start feeling better to prevent potential relapse or withdrawal effects.

5. A 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.
