1. A patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?
- A. With meals
- B. At bedtime
- C. Before meals
- D. After meals
Correct answer: C
Rationale: Omeprazole is best taken before meals for optimal effectiveness in reducing stomach acid production and promoting ulcer healing. Taking it before meals allows the medication to act on the proton pumps before food intake triggers acid production, thereby maximizing its therapeutic benefits. Choices A, B, and D are incorrect because taking omeprazole with meals, at bedtime, or after meals may not align with its mechanism of action, potentially reducing its effectiveness in managing peptic ulcer disease.
2. The nurse is providing an educational workshop about coronary artery disease (CAD) and its risk factors. The nurse explains to participants that CAD has many risk factors, some that can be controlled and some that cannot. What risk factors should the nurse list that can be controlled or modified?
- A. Gender, obesity, family history, and smoking
- B. Inactivity, stress, gender, and smoking
- C. Cholesterol levels, hypertension, and smoking
- D. Stress, family history, and obesity
Correct answer: C
Rationale: Cholesterol levels, hypertension, and smoking are controllable risk factors for CAD. Managing these factors through lifestyle changes and medical interventions can help reduce the risk of developing coronary artery disease.
3. A 56-year-old woman presents to discuss the results of her recent upper endoscopy. She was having some mild abdominal pain, so she underwent the procedure, which revealed an ulcer in the antrum of the stomach. Biopsy of the lesion revealed the presence of H. pylori. All of the following statements regarding her condition are correct except
- A. H. pylori has been associated with gastric MALT (mucosa-associated lymphoid tissue)
- B. Reinfection is rare despite adequate treatment
- C. Triple drug therapy has been shown to be more effective than dual drug therapy
- D. If her H. pylori IgG antibody titer was elevated prior to therapy, it can be used to monitor treatment efficacy
Correct answer: B
Rationale: H. pylori is associated with a majority of peptic ulcer disease cases and has links to gastric MALT and adenocarcinoma. Triple drug therapy is more effective than dual therapy. Reinfection after adequate treatment is rare. While urea breath testing is a better diagnostic tool, quantitative serology can monitor treatment efficacy. A 30% decrease in IgG titer should occur post-therapy, indicating effectiveness.
4. A patient with chronic kidney disease (CKD) is prescribed erythropoietin. What is the primary action of this medication?
- A. Stimulate white blood cell production
- B. Increase platelet count
- C. Promote red blood cell production
- D. Enhance clotting factor production
Correct answer: C
Rationale: Erythropoietin primarily stimulates the bone marrow to produce more red blood cells, which helps to improve oxygen delivery to tissues. In chronic kidney disease, patients often develop anemia due to reduced erythropoietin production by the kidneys. By administering exogenous erythropoietin, the deficient hormone is replaced, leading to an increase in red blood cell production and subsequently improving the oxygen-carrying capacity of the blood.
5. A client with type 1 diabetes mellitus is admitted with hyperglycemia. Which laboratory result requires the most immediate intervention?
- A. Serum glucose of 350 mg/dL.
- B. Serum potassium of 2.8 mEq/L.
- C. Serum sodium of 136 mEq/L.
- D. Serum bicarbonate of 20 mEq/L.
Correct answer: B
Rationale: A serum potassium level of 2.8 mEq/L is critically low and can cause cardiac arrhythmias, requiring immediate intervention. Hypokalemia is a life-threatening condition that needs prompt correction to prevent serious complications. High serum glucose levels (choice A) are a concern in diabetes but do not pose an immediate life-threatening risk compared to severe hypokalemia. Serum sodium (choice C) and serum bicarbonate levels (choice D) are within normal ranges and do not require immediate intervention.
