Question 1 of 5
The physical half life of radioactive 131I is:
Correct Answer: D
Rationale: The correct answer is D: 60 days. This is because the physical half-life of a radioactive substance refers to the time it takes for half of the radioactive atoms to decay. In the case of 131I, it has a physical half-life of 8 days. However, 131I undergoes beta decay to form stable xenon-131, which has a longer half-life. Therefore, the effective half-life of 131I is longer, approximately 60 days. Summary: A: 8 hours - Incorrect, too short for the physical half-life of 131I. B: 8 days - Partially correct, but the effective half-life is longer. C: 16 days - Incorrect, not the effective half-life of 131I. D: 60 days - Correct, reflects the effective half-life of 131I due to its decay process.
Question 2 of 5
The duration of action of insulin-zinc suspension (lente insulin) is:
Correct Answer: B
Rationale: The correct answer is B: 8-10 hours. Lente insulin is a type of intermediate-acting insulin that typically lasts around 8-10 hours. This is because it is a mixture of insulin crystals and zinc, which delays its absorption and extends its duration of action. Choice A (2-4 hours) is too short for lente insulin. Choice C (20-24 hours) and D (30-36 hours) are too long for lente insulin, which is considered intermediate-acting. Therefore, the correct answer is B as it aligns with the expected duration of action for lente insulin.
Question 3 of 5
Insulin therapy is required for the following category/categories of type 2 diabetes mellitus patients:
Correct Answer: D
Rationale: Insulin therapy is required for patients with ketoacidosis to lower blood glucose levels. Patients undergoing surgery may need insulin to manage blood sugar fluctuations. Pregnant diabetics often require insulin to maintain stable blood sugar levels for fetal health. Therefore, the correct answer is D, as all the mentioned categories of type 2 diabetes patients may benefit from insulin therapy. Choices A, B, and C are incorrect because insulin therapy may be necessary for each of these specific patient groups due to their unique medical needs related to type 2 diabetes.
Question 4 of 5
The second generation sulfonylurea hypoglycaemics differ from the first generation ones in that they:
Correct Answer: D
Rationale: Step 1: Second generation sulfonylureas like glimepiride and glipizide are less likely to cause hypoglycemic reactions compared to first generation ones like chlorpropamide and tolbutamide. Step 2: This is because second generation drugs have a shorter duration of action and are more selective for pancreatic beta cells, reducing the risk of hypoglycemia. Step 3: Therefore, option D is correct as it accurately reflects the difference between the two generations in terms of hypoglycemic risk. Summary: - Option A is incorrect because both generations can be potent in lowering blood sugar. - Option B is incorrect as second generation drugs are not necessarily longer acting. - Option C is incorrect as sulfonylureas lower blood sugar regardless of the patient's diabetic status.
Question 5 of 5
The hypoglycaemic action of sulfonylureas is likely to be reduced by the concurrent use of:
Correct Answer: B
Rationale: The correct answer is B, Propranolol. Propranolol is a beta-blocker that can mask the symptoms of hypoglycemia, making it difficult to recognize and treat low blood sugar levels. This can lead to severe hypoglycemia if not properly managed. Hydrochlorothiazide (A) is a diuretic, Theophylline (C) is a bronchodilator, and Aspirin (D) is a pain reliever, none of which directly affect the hypoglycemic action of sulfonylureas.
