Correct Answer: B

Rationale: The correct answer is B: helicobacter pylori infection. This bacterium is a major cause of peptic ulcers by weakening the protective mucous layer of the stomach and duodenum. Research has shown a strong association between H. pylori infection and peptic ulcer development. Genetic defects in the gastric mucosa (choice A) are not a proven cause of peptic ulcers. While a high-fat diet (choice C) can exacerbate symptoms, it is not the primary cause. Work-related stress (choice D) may exacerbate symptoms but is not a direct cause of peptic ulcers. Therefore, choice B is the most supported and logical answer based on current research findings.

Correct Answer: C

Rationale: The correct answer is C: Maintaining the integrity of the urinary system. This is crucial in preoperative preparation for a client with malignant tumors to prevent complications such as urinary obstruction or infection. Assessing symptoms of peritonitis (B) is important but not as critical as ensuring urinary system integrity. Insertion of an ostomy pouch (A) and nasogastric tube diversion procedure (D) may be necessary interventions for some cases, but they are not as essential as ensuring the urinary system's integrity to prevent serious complications.

Correct Answer: A

Rationale: The correct answer is A: Filtration. Albumin is a large protein molecule that cannot pass through the semipermeable membrane of blood vessels. Therefore, the shift of body fluids associated with intravenous albumin administration occurs through the process of filtration, where fluid moves across the membrane due to a pressure difference. Osmosis (B) involves the movement of water across a semipermeable membrane, which is not the case for albumin. Diffusion (C) is the movement of molecules from an area of high concentration to low concentration, which is not how albumin moves. Active transport (D) requires energy to move substances against a concentration gradient, which is not the mechanism for albumin movement in the body.

Correct Answer: A

Rationale: The correct answer is A (5 to 10 mcg/ml) because this range is typically considered therapeutic for phenytoin (Dilantin) for seizure control. Levels below 5 mcg/ml may be subtherapeutic, leading to inadequate seizure control. Levels above 10 mcg/ml can increase the risk of toxicity. Choices B, C, and D are incorrect because they are outside the optimal therapeutic range, leading to either ineffective treatment (B, C) or an increased risk of adverse effects (D). Monitoring drug levels helps ensure the medication's effectiveness while minimizing side effects.

Correct Answer: A

Rationale: Correct Answer: A - Apply immobilization device after examination by physician Rationale: 1. Immobilization helps reduce pain and prevent further injury. 2. Physician examination ensures proper diagnosis and treatment plan. 3. Immobilization device may include chest binders or splints for support. 4. It is crucial to follow medical advice to prevent complications. Summary: B: Discouraging deep breaths can lead to respiratory complications. C: Advising against analgesics can increase pain and hinder recovery. D: Increased fluid intake is important but not directly related to rib fracture care.
