1. In a patient with a history of chronic iron deficiency anemia requiring a recent blood transfusion and an extensive GI work-up, which statement is true based on their medications?

• A. A dedicated small bowel series has a high likelihood of being positive
• B. 81 mg of aspirin per day decreases the benefit of using a COX II inhibitor
• C. The patient should have a provocative arteriogram with heparin infusion to identify the source of blood loss
• D. Hormonal therapy has been shown to be effective in decreasing blood loss due to arteriovenous malformations

Correct answer: B

Rationale: The correct answer is B. Taking even a low dose of aspirin per day, such as 81 mg, can reduce the protective effect on the gastrointestinal mucosa that is gained from using a COX II selective inhibitor. Aspirin can increase the risk of gastrointestinal bleeding, which can counteract the benefits of COX II inhibitors in protecting the stomach lining.

2. A client with chronic renal failure is prescribed erythropoietin (Epogen). Which outcome indicates that the medication is effective?

• A. Increased urine output.
• B. Improved hemoglobin levels.
• C. Decreased blood pressure.
• D. Stable potassium levels.

Correct answer: B

Rationale: The correct answer is B: Improved hemoglobin levels. Erythropoietin (Epogen) stimulates red blood cell production, leading to an increase in hemoglobin levels in clients with chronic renal failure. Monitoring hemoglobin levels is crucial to assess the effectiveness of erythropoietin therapy in managing anemia associated with chronic renal failure. While increased urine output, decreased blood pressure, and stable potassium levels are important parameters to monitor in clients with renal failure, they are not direct indicators of the effectiveness of erythropoietin therapy.

3. A 70-year-old woman presents with fatigue, anorexia, and weight loss. She has noticed darkening of her skin, particularly in sun-exposed areas. Laboratory tests reveal hyponatremia, hyperkalemia, and low cortisol levels. What is the most likely diagnosis?

• A. Cushing's syndrome
• B. Addison's disease
• C. Hypothyroidism
• D. Pheochromocytoma

Correct answer: B

Rationale: The combination of symptoms such as fatigue, anorexia, weight loss, hyperpigmentation of the skin, along with hyponatremia, hyperkalemia, and low cortisol levels, points towards Addison's disease. This condition is characterized by adrenal insufficiency, leading to a deficiency in cortisol and aldosterone production.

4. 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.

5. A male client is admitted to the neurological unit. He has just sustained a C-5 spinal cord injury. Which assessment finding of this client warrants immediate intervention by the nurse?

• A. Is unable to feel sensation in the arms and hands.
• B. Has flaccid upper and lower extremities.
• C. Blood pressure is 110/70 and the apical pulse is 68.
• D. Respirations are shallow, labored, and 14 breaths/minute.

Correct answer: D

Rationale: Respirations that are shallow, labored, and at 14 breaths/minute indicate potential respiratory compromise, which is a critical situation requiring immediate intervention to maintain adequate oxygenation and prevent respiratory failure.
