Which statement best describes atherosclerotic disease affecting the cerebrovascular, cardiovascular, and peripheral vascular systems in patients with diabetes?

Correct Answer: B

Rationale: The correct answer is B) It occurs with a higher frequency and earlier onset than in the nondiabetic population. Explanation: Atherosclerotic disease affecting the cerebrovascular, cardiovascular, and peripheral vascular systems in patients with diabetes is a well-documented phenomenon. Diabetes, especially type 2 diabetes, is a significant risk factor for the development of atherosclerosis due to various factors like hyperglycemia, insulin resistance, inflammation, and dyslipidemia. Individuals with diabetes have a higher prevalence and earlier onset of atherosclerotic disease compared to those without diabetes. This increased risk is attributed to the chronic impact of high blood sugar levels on blood vessels, leading to endothelial dysfunction and accelerated atherosclerosis progression. Now, let's analyze why the other options are incorrect: A) It can be prevented by tight glucose control. While tight glucose control is essential in managing diabetes and reducing the risk of complications, atherosclerotic disease in patients with diabetes is a complex multifactorial process that cannot be solely prevented by glucose control. C) It is caused by the hyperinsulinemia related to insulin resistance common in type 2 diabetes. Hyperinsulinemia and insulin resistance are indeed common in type 2 diabetes, but they contribute to the development of diabetes complications through various mechanisms, not directly causing atherosclerotic disease in the described vascular systems. D) It cannot be modified by reduction of risk factors such as smoking, obesity, and high-fat intake. This statement is inaccurate. Modifiable risk factors such as smoking cessation, weight management, and dietary changes play a crucial role in reducing the risk and progression of atherosclerotic disease in patients with diabetes. Lifestyle modifications are a cornerstone in the management of atherosclerosis in diabetic individuals. Educational Context: Understanding the increased risk and early onset of atherosclerotic disease in patients with diabetes is crucial for healthcare professionals involved in their care. Educating patients about the importance of comprehensive risk factor management, including glucose control, lifestyle modifications, and regular monitoring, is essential in reducing the burden of atherosclerosis-related complications in diabetes. This knowledge empowers both healthcare providers and patients to work collaboratively towards preventing and managing atherosclerotic disease effectively in the diabetic population.

Correct Answer: A

Rationale: In the scenario of a patient with parathyroid disease experiencing symptoms of hypocalcemia, the correct measure to temporarily raise serum calcium levels is to administer IV normal saline (Option A). This is because IV normal saline contains sodium chloride, which can help increase serum calcium levels by promoting the movement of calcium from the bones into the bloodstream. Option B, administering furosemide (Lasix), is incorrect as it is a diuretic that promotes the excretion of fluids and electrolytes, including calcium, leading to a potential decrease in serum calcium levels. Option C, having the patient rebreathe in a paper bag, is not a suitable intervention for hypocalcemia. This technique is used to treat respiratory alkalosis by increasing carbon dioxide levels, not for addressing low calcium levels. Option D, administering oral phosphorus supplements, is also incorrect. While phosphorus and calcium levels are interrelated, giving phosphorus supplements may not directly address the immediate need to raise serum calcium levels in a patient with hypocalcemia. Educationally, understanding the appropriate interventions for managing electrolyte imbalances is crucial for healthcare providers, especially when caring for patients with endocrine disorders like parathyroid disease. This case highlights the importance of knowing the effects of different interventions on electrolyte levels and choosing the most appropriate treatment based on the specific electrolyte imbalance present.

Correct Answer: A

Rationale: The correct answer is A) Mrs. Good has not been receiving close medical supervision. This is because phenformin hydrochloride (DBI) has been withdrawn from the market due to its association with lactic acidosis, a serious side effect. Therefore, the fact that Mrs. Good has been taking this medication for years indicates a lack of close medical supervision, as a healthcare provider would have likely switched her to a safer medication. Option B) Mrs. Good having moderately severe diabetes cannot be determined solely based on her use of phenformin hydrochloride. The severity of diabetes is assessed through various factors such as blood sugar levels, complications, and treatment response. Option C) Mrs. Good having active beta-cell function is not related to her use of phenformin hydrochloride. Beta-cell function is determined through specific tests assessing insulin production by the pancreas. Option D) Mrs. Good needing to switch to insulin therapy cannot be conclusively inferred from her use of phenformin hydrochloride. The decision to switch to insulin therapy depends on various factors including blood sugar control, medication effectiveness, and individual patient needs. In an educational context, this question highlights the importance of medication safety and close medical supervision for patients with chronic conditions like diabetes. It emphasizes the need for healthcare providers to regularly review and adjust treatment plans to ensure optimal patient outcomes and avoid potential risks associated with medications.

Correct Answer: D

Rationale: In this scenario, the correct answer is D) hypoglycemia. Hypoglycemia occurs when blood sugar levels drop too low. Miss White, being a diabetic, is likely experiencing these symptoms due to low blood sugar levels. Headache, weakness, irritability, lack of muscular coordination, and apprehension are all common early signs of hypoglycemia. Option A) diabetic ketoacidosis is incorrect because it is a complication of uncontrolled diabetes characterized by high blood sugar levels and the presence of ketones in the blood. Option B) hyperglycemic hyperosmolar nonketotic coma is also incorrect as it is a severe complication of diabetes with very high blood sugar levels but without ketones. Option C) microangiopathy is a long-term complication of diabetes affecting small blood vessels and is not related to the acute symptoms described. In an educational context, it is crucial for healthcare professionals to recognize the early signs of hypoglycemia in diabetic patients as prompt intervention is necessary to prevent progression to severe outcomes like seizures or loss of consciousness. Understanding the differences between hypoglycemia and other diabetic complications is essential for providing appropriate care and ensuring patient safety.

Correct Answer: C

Rationale: In Mrs. K's case of hyperthyroidism undergoing radioactive iodine therapy, the correct answer is C) You will need to avoid close contact with others for several days. This instruction is crucial as the radioactive iodine therapy can make the patient emit radiation, which can be harmful to others, especially pregnant women and children. Option A is incorrect because in hyperthyroidism, the goal is usually to decrease thyroid hormone levels, so taking a thyroid hormone supplement after treatment would be counterproductive. Option B is incorrect because radioactive iodine therapy requires precautions due to radiation exposure, and immediate resumption of usual activities can pose risks to others. Option D is incorrect because increasing iodized salt intake is not recommended post-radioactive iodine therapy; in fact, patients are often advised to limit iodine intake to prevent interference with treatment efficacy. Educationally, understanding the rationale behind each option enhances the student's grasp of the importance of radiation safety measures in treating hyperthyroidism with radioactive iodine therapy and reinforces the need for tailored patient education based on specific treatment modalities.
