Endocrinology Practice Questions Questions
Question 1 of 5
All of the following are consistent with non-proliferative diabetic retinopathy except:
Correct Answer: C
Rationale: The correct answer is C: Neovascularization. Non-proliferative diabetic retinopathy is characterized by early changes such as retinal vascular microaneurysms, blot hemorrhages, and cotton-wool spots. Neovascularization is a feature of proliferative diabetic retinopathy, not non-proliferative. Neovascularization refers to the growth of abnormal new blood vessels in the retina, which can lead to severe vision loss if not treated promptly. In summary, neovascularization is not consistent with non-proliferative diabetic retinopathy, as it is a hallmark of the proliferative stage.
Question 2 of 5
Which of the following statements regarding Cushing's syndrome is correct?
Correct Answer: B
Rationale: Step-by-step rationale for why answer B is correct: 1. Cushing's syndrome is characterized by excess cortisol production. 2. Women are more likely to develop Cushing's syndrome due to hormonal differences. 3. Women have higher cortisol levels naturally, making them more susceptible. 4. Men can still develop Cushing's syndrome but at a lower rate compared to women. Summary: A: Incorrect, as women are more likely to develop Cushing's syndrome. C: Incorrect, as the incidence is higher in women due to hormonal factors. D: Incorrect, as it refers to thyroid hormones, not cortisol in Cushing's syndrome.
Question 3 of 5
Features of Addison's disease do not include:
Correct Answer: A
Rationale: The correct answer is A: Diarrhea. Addison's disease is a condition where the adrenal glands do not produce enough hormones. Diarrhea is not a typical symptom of Addison's disease. The characteristic features include fatigue, weakness, weight loss, dizziness (B), hyperpigmentation, low blood pressure, dehydration (D), and skin changes like dermatitis is common (C). Therefore, diarrhea does not align with the typical symptoms of Addison's disease.
Question 4 of 5
Which of the following is not a part of metabolic 'syndrome X'?
Correct Answer: C
Rationale: The correct answer is C: Ischaemic heart disease. Metabolic syndrome X consists of a cluster of conditions, including hyperlipidemia, obesity, hypertension, and insulin resistance. Ischaemic heart disease, while commonly associated with metabolic syndrome X due to the increased risk factors, is not a direct component of the syndrome itself. Therefore, it is not considered a part of metabolic syndrome X. Hyperlipidemia (A), obesity (B), and hypertension (D) are all key components of metabolic syndrome X due to their association with insulin resistance and increased risk of cardiovascular disease.
Question 5 of 5
Which of the following visual field deficits is most likely present in a patient with pituitary adenoma compressing his optic chiasm?
Correct Answer: C
Rationale: The correct answer is C: Bi-temporal hemianopia. Pituitary adenoma compressing the optic chiasm typically leads to bi-temporal hemianopia due to compression of the crossing fibers from the nasal visual fields. This results in loss of peripheral vision in both temporal visual fields. A: Bilateral inferior visual field deficits and B: Bilateral superior visual field deficits are less likely as they are not typical patterns associated with optic chiasm compression. D: Right homonymous hemianopia is incorrect as it is not associated with compression of the optic chiasm by a pituitary adenoma.
