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 60-year-old man 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 presentation of a 60-year-old man with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria strongly suggests type 1 diabetes mellitus. Type 1 diabetes typically presents with acute symptoms due to absolute insulin deficiency, leading to hyperglycemia and ketonuria. Conversely, type 2 diabetes often presents more insidiously and is associated with relative insulin deficiency and insulin resistance. Diabetes insipidus, a condition characterized by excessive thirst and excretion of large amounts of dilute urine, is due to problems with antidiuretic hormone (ADH) and is not associated with hyperglycemia or ketonuria. Hyperthyroidism, while also presenting with symptoms like fatigue, does not typically manifest with hyperglycemia or ketonuria. Therefore, based on the clinical presentation and laboratory findings, the most likely diagnosis in this case is type 1 diabetes mellitus.
3. A patient with chronic pain is prescribed gabapentin. What is the primary purpose of this medication?
- A. Relieve neuropathic pain
- B. Reduce inflammation
- C. Enhance opioid analgesia
- D. Suppress cough
Correct answer: A
Rationale: Gabapentin is primarily prescribed to relieve neuropathic pain. It works by stabilizing electrical activity in the nerves, making it effective in managing conditions such as diabetic neuropathy, postherpetic neuralgia, and other forms of chronic pain originating from nerve damage.
4. What instruction should the nurse give regarding the administration of alendronate to a patient with osteoporosis?
- A. Take the medication with milk.
- B. Lie down for 30 minutes after taking the medication.
- C. Take the medication with a full glass of water.
- D. Take the medication before bedtime.
Correct answer: C
Rationale: The correct instruction for administering alendronate to a patient with osteoporosis is to take the medication with a full glass of water first thing in the morning. It is important for the patient to remain upright for at least 30 minutes after taking the medication to prevent esophageal irritation. Taking alendronate with milk, lying down after intake, or taking it before bedtime can reduce the medication's effectiveness or increase the risk of side effects.
5. A 50-year-old man presents with progressive jaundice, dark urine, and pruritus. Imaging reveals a mass in the head of the pancreas. What is the most likely diagnosis?
- A. Pancreatic cancer
- B. Chronic pancreatitis
- C. Gallstones
- D. Primary sclerosing cholangitis
Correct answer: A
Rationale: The presentation of progressive jaundice, dark urine, and pruritus along with a pancreatic mass, particularly in the head of the pancreas, strongly suggests pancreatic cancer as the most likely diagnosis. These symptoms are classic for obstructive jaundice caused by a mass in the head of the pancreas, making pancreatic cancer the most fitting choice.
