A patient with type 2 diabetes mellitus presents with a consistently elevated A1C despite adherence to prescribed oral hypoglycemic agents and lifestyle modifications. Which of the following interventions should be prioritized to optimize glycemic control and mitigate long-term complications?
- Implementing a structured exercise program consisting of high-intensity interval training (HIIT) to enhance insulin sensitivity and promote weight loss.
- Prescribing a statin medication to address potential hyperlipidemia.
- Referring the patient for bariatric surgery evaluation, considering its potential to induce remission of type 2 diabetes and improve overall metabolic health.
- Initiating intensive insulin therapy with a basal-bolus regimen, coupled with continuous glucose monitoring (CGM) to achieve tighter glycemic control. (correct)

Study Notes
- Addison's disease primary clinical features include progressive weakness, fatigue, weight loss, anorexia, skin hyperpigmentation, orthostatic hypotension, hyponatremia, hyperkalemia, nausea and vomiting, diarrhea, irritability, depression, and low blood pressure.
- Hypophysectomy involves the removal of the pituitary gland.
- Low blood pressure can result from hypophysectomy due to diabetes insipidus.
- Diabetes insipidus causes fluid deficits and fluid loss.
- Hypoglycemia is managed with 5% dextrose and glucagon.
- Compliance with diabetes medication is tested using A1C.
- Hypoglycemia in the range of 38-30 is dangerous and can cause neurological damage.
- High serum osmolarity is characteristic of hyperosmolar hyperglycemic nonketotic syndrome (HHNS).
- Testicular cancer treatments include radiation, chemotherapy, and surgery, and can lead to sperm destruction.
- Teaching about self-examination is crucial for patients with testicular cancer.
- Management of type 2 diabetes complications focuses on long-term care.
- Adrenal deficiency managment involves restoring circulation and managing fluids.
- Diabetes insipidus and diabetes mellitus are distinct and not related
- Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is associated with low serum osmolarity.
- Non-pharmaceutical interventions for diabetes include diet and exercise.
- High blood pressure necessitates further testing.
- Acromegaly assessment includes observing for a deepened voice, an indication of growth hormone overproduction.
- A water deprivation test is used to diagnose diabetes insipidus.
- Desmopressin (DDAVP) is used in diabetes insipidus as a hormone replacement for ADH.
- Fatigue is a clinical manifestation of SIADH.
- Postoperative adrenal deficiency is a significant risk following surgery.
Cushing's Syndrome Clinical Manifestations
- Protein wasting and catabolic effects of cortisol cause weakness, especially in the extremities.
- Protein loss in bones leads to osteoporosis and bone/back pain
- Collagen loss delays wound healing.
- Mood disturbances, insomnia, irrationality, and psychosis can occur.
- Mineralocorticoid excess may cause hypertension due to fluid retention.
- Adrenal androgen excess can cause pronounced acne, virilization in women, and feminization in men.
- Adrenal androgen excess is more commonly seen in adrenal carcinomas.
- Women may experience menstrual disorders and hirsutism
- Men may experience gynecomastia and impotence
- Purplish red striae may appear on the abdomen, breasts, or buttocks.
- Hypofunction of the adrenal gland leads to Addison's syndrome, while hyperfunction leads to Cushing's syndrome.
- Hypoglycemia management includes 5% dextrose IV and glucagon if IV access is unavailable.
- Hyperosmolar hyperglycemic nonketotic syndrome (HHNS) is characterized by high serum osmolarity due to dehydration.
