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. 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.
3. A client's telemetry monitor indicates the sudden onset of ventricular fibrillation. Which assessment finding should the nurse anticipate?
- A. Bounding erratic pulse.
- B. Regularly irregular pulse.
- C. Thready irregular pulse.
- D. No palpable pulse.
Correct answer: D
Rationale: Ventricular fibrillation is a life-threatening arrhythmia characterized by chaotic, asynchronous contractions of the ventricles, resulting in ineffective cardiac output. This leads to the absence of a palpable pulse. Nurses should be prepared to initiate immediate interventions such as defibrillation to restore normal cardiac rhythm in a client experiencing ventricular fibrillation.
4. Which regimen is most effective for treating H. pylori infection?
- A. Metronidazole, bismuth subsalicylate, amoxicillin for 14 days
- B. Clarithromycin and omeprazole for 14 days
- C. Metronidazole, lansoprazole, and clarithromycin for 14 days
- D. Metronidazole, clarithromycin, and omeprazole for 7 days
Correct answer: C
Rationale: Regimen C, which consists of metronidazole, lansoprazole, and clarithromycin for 14 days, is recommended by the FDA as an effective treatment for H. pylori infection. This regimen has been shown to have a high eradication rate and is a standard recommendation in clinical practice guidelines for the management of H. pylori-related conditions.
5. The healthcare provider is caring for a client who has just undergone a thyroidectomy. Which assessment finding requires immediate intervention?
- A. Hoarse voice.
- B. Difficulty swallowing.
- C. Numbness and tingling around the mouth.
- D. Sore throat.
Correct answer: C
Rationale: Numbness and tingling around the mouth can indicate hypocalcemia, a potential complication after thyroidectomy. Hypocalcemia can occur due to inadvertent injury or removal of the parathyroid glands during the thyroidectomy, leading to decreased calcium levels. As a result, the client may experience symptoms such as numbness, tingling, muscle cramps, or spasms. Prompt intervention is necessary to prevent severe complications like tetany or seizures. Therefore, the healthcare provider should address numbness and tingling around the mouth immediately to prevent further deterioration of calcium levels and potential serious outcomes. Choices A, B, and D are not typically associated with immediate post-thyroidectomy complications and can be addressed after ensuring the client's calcium levels are stable.
