Q11A man with type 2 diabetes has been taking lorcaserin for weight management for more than a year and is now planning to start a new medication for his depression. Due to potential drug interactions, lorcaserin will need to be discontinued. Discontinuation should be preceded by taking a dose every other day for a week to _______________.
✓ Correct answer: B. Prevent serotonin syndrome
Answer: Discontinuation should be preceded by taking a dose every other day for a week to prevent serotonin syndrome. There are warnings for lorcaserin due to the risk of serotonin syndrome, which can occur when lorcaserin is discontinued rapidly or if there is an interaction with other serotonergic drugs. Symptoms of serotonin syndrome include agitation, hallucinations, tachycardia, labile blood pressure, hyperthermia, and gastrointestinal symptoms. Lorcaserin is a serotonin 2C receptor agonist used for weight management in patients with type 2 diabetes. Rapid discontinuation is associated with serotonin syndrome, not severe hypotension or significant changes in blood glucose levels.
Q12Which of the following is NOT considered a complication of poorly controlled diabetes?
✓ Correct answer: A. Seasonal allergies
Answer: Seasonal allergies Seasonal allergies are not associated with poorly controlled diabetes. Neuropathy, retinopathy, and cardiovascular disease are common complications of diabetes. Poorly controlled blood glucose levels can lead to damage in various organs and systems, resulting in neuropathy (nerve damage), retinopathy (eye damage), and cardiovascular disease (heart-related conditions).
Q13A client attending a diabetes education session for the first time presents with a HbA1c level of 9%. Based on the American Diabetes Association (ADA) diabetes management guidelines, the patient's HbA1c level indicates:
✓ Correct answer: D. The patient is at high risk of diabetes-related complications
Answer: The patient is at high risk of diabetes-related complications According to ADA guidelines, a HbA1c level of 9% indicates poor glycemic control and places the patient at a higher risk for diabetes complications, such as retinopathy, neuropathy, and cardiovascular diseases. The patient requires immediate intervention, including potential adjustments in medication, lifestyle changes, and regular monitoring of their blood glucose levels. Immediate insulin therapy might be necessary depending on individual patient assessment, but it is not an automatic requirement for all patients with a high HbA1c. On the other hand, advising the patient to decrease physical activity would be counterproductive as physical activity is generally recommended to improve glycemic control.
Q14A patient with type 2 diabetes is concerned about starting insulin therapy due to potential side effects. On which of the following statements about insulin therapy should the nurse base their response?
✓ Correct answer: C. Insulin therapy can be adjusted to minimize side effects while effectively managing blood glucose levels.
Answer: Insulin therapy can be adjusted to minimize side effects while effectively managing blood glucose levels. Insulin therapy can be personalized to meet individual needs, balancing insulin type, timing, and dosage. The goal is to manage blood glucose levels effectively while minimizing potential side effects. Regular monitoring and adjustments allow for flexibility and tailored management strategies. Contrary to the distractors, insulin therapy does not always lead to a permanent requirement for insulin, does not inherently cause weight loss, and extreme carbohydrate restriction is unnecessary as insulin helps in metabolizing the carbs efficiently.
Q15A diabetes educator is counseling a group of female diabetics about preventing complications related to diabetes. Which of the following statements made by a client indicates the need for more instruction?
✓ Correct answer: B. "Only women with type 1 diabetes develop neuropathy."
Answer: "Only women with type 1 diabetes develop neuropathy." Neuropathy can affect individuals with both type 1 and type 2 diabetes. Chronic high blood sugar levels can damage nerves throughout the body, most commonly causing neuropathy in the legs and feet. It is essential for all diabetics to manage their blood sugar levels to prevent neuropathy. Managing blood sugar helps to prevent various complications including retinopathy, which affects the eyes, and maintaining healthy blood pressure levels also plays an important role in protecting kidney function.
Q16A dietitian is evaluating a diabetic male with type 2 diabetes for lifestyle factors contributing to potential diabetic complications. The dietitian knows that:
✓ Correct answer: A. High intake of saturated fats increases the risk of cardiovascular disease due to increased cholesterol levels
Answer: High intake of saturated fats increases the risk of cardiovascular disease due to increased cholesterol levels If a client has a high intake of saturated fats, they should reduce this intake to lower cholesterol. Increased cholesterol levels are linked to cardiovascular disease. While fish oil supplements are generally recommended for heart health, they do not significantly increase the risk of diabetic complications. The American Heart Association recommends a target LDL cholesterol level of less than 100 mg/dL, not 130 mg/dL. Men have a higher risk of cardiovascular disease until about age 45, women catch up between 45 and 54, and surpass men at age 55 and beyond.
Q17A 65-year-old patient with Type 2 Diabetes is receiving education about potential complications associated with aging and diabetes management. Which of the following statements is accurate?
✓ Correct answer: D. Aging is associated with a decreased response to incretin hormones.
Aging is related to a decrease in the response to incretin hormones, which affects insulin secretions. The alterations in insulin release, loss of pulsatility, and first-phase insulin secretion are also contributing factors. Compared to younger adults, obese, rather than lean older people with diabetes, have relatively normal insulin secretion but significant resistance to insulin-mediated glucose disposal. Lean, rather than obese older people with diabetes, exhibit a profound impairment in glucose-induced insulin secretion but minimal resistance to insulin action. Older adults with diabetes show normal fasting hepatic glucose production, unlike the elevated hepatic glucose production in younger diabetes patients.
Q18Which of the following statements about exercise recommendations for diabetes management is INCORRECT?
✓ Correct answer: C. Individuals with type 1 diabetes should engage in exercise immediately after insulin administration.
Answer: Individuals with type 1 diabetes should engage in exercise immediately after insulin administration. For individuals with type 1 diabetes, it is recommended to avoid exercise immediately after insulin administration as it may increase the risk of hypoglycemia. Instead, they should exercise at a time when insulin levels and blood glucose levels are more stable. Physical activity is beneficial for people with diabetes as it improves insulin sensitivity, helps lower blood glucose levels, and assists in overall diabetes management. Exercise is an important component of managing both type 1 and type 2 diabetes.
Q19A diabetes educator is teaching a group of patients with type 2 diabetes about factors impacting glycemic control. All of the following can negatively affect glycemic control EXCEPT :
✓ Correct answer: B. Regular physical activity
Answer: Regular physical activity Regular physical activity can help improve glycemic control in individuals with type 2 diabetes. In contrast, a high carbohydrate diet, sedentary lifestyle, and stress are known to negatively affect glycemic control.
Q20During a community diabetes education session, a participant shares that they have been experiencing frequent dizzy spells that they suspect are due to low blood sugar. What is the BEST immediate response by the educator?
✓ Correct answer: A. Advise the participant to immediately check their blood sugar levels and consume a fast-acting carbohydrate if levels are low.
Answer: Advise the participant to immediately check their blood sugar levels and consume a fast-acting carbohydrate if levels are low. Frequent dizzy spells could signify low blood sugar, a condition that requires prompt action to prevent further complications. Consuming a fast-acting carbohydrate is the standard treatment for hypoglycemia, and checking blood sugar levels helps confirm the cause of the symptoms. Other actions, such as resting or planning a future physician visit, do not provide the immediate intervention necessary to address potential hypoglycemia.
