Stress incontinence occurs because of:
Medications
Hypertension
Full bladder
Exertional stimulus
The Correct Answer is D
Choice A reason: While certain medications can affect bladder control, they are not the primary cause of stress incontinence. Stress incontinence is specifically related to physical exertion and increased pressure on the bladder, leading to involuntary urine leakage.
Choice B reason: Hypertension, or high blood pressure, is not a direct cause of stress incontinence. Stress incontinence is related to the weakening of pelvic floor muscles and increased intra-abdominal pressure rather than blood pressure levels.
Choice C reason: A full bladder can increase the likelihood of urine leakage in individuals with stress incontinence, but it is not the underlying cause. Stress incontinence occurs due to weakened pelvic floor muscles and increased pressure during physical activities.
Choice D reason: Stress incontinence occurs due to exertional stimuli that increase intra-abdominal pressure, such as coughing, sneezing, laughing, or physical exercise. These activities cause a sudden increase in pressure on the bladder, leading to involuntary urine leakage. The condition is often associated with weakened pelvic floor muscles, which can result from factors such as childbirth, aging, or pelvic surgery.

Correct Answer is C
Explanation
Choice A reason: Positive feedback mechanisms amplify changes or deviations in the body. They are less common in physiological processes and typically drive processes to completion, such as childbirth and blood clotting. The regulation of blood glucose levels does not operate on a positive feedback mechanism.
Choice B reason: Releasing hormones are typically involved in the hypothalamic-pituitary axis and the regulation of hormone secretion from other endocrine glands. Examples include thyrotropin-releasing hormone (TRH) and gonadotropin-releasing hormone (GnRH). Insulin secretion in response to blood glucose levels is not directly controlled by releasing hormones.
Choice C reason: Negative feedback is the primary mechanism by which homeostasis is maintained in the body. When blood glucose levels rise, the pancreas secretes insulin to lower blood glucose levels, restoring them to normal. This is an example of negative feedback, as the increase in glucose levels triggers a response (insulin secretion) that counteracts the initial change, bringing blood glucose back to its set point.
Choice D reason: Ectopic hormones are hormones produced by tissues that normally do not produce hormones, often in cases of tumors or certain disease conditions. The regulation of insulin in response to blood glucose levels does not involve ectopic hormone production.
Correct Answer is A
Explanation
Choice A reason: Type 1 diabetes cannot be treated with oral glycemic agents. These medications are typically used to manage type 2 diabetes, which is characterized by insulin resistance rather than a lack of insulin production. In type 1 diabetes, the pancreas is unable to produce insulin due to an autoimmune destruction of insulin-producing beta cells. Therefore, individuals with type 1 diabetes require insulin therapy to manage their blood glucose levels effectively.
Choice B reason: Type 1 diabetes has a definite genetic component, though it is not solely determined by genetics. A combination of genetic predisposition and environmental factors, such as viral infections or other autoimmune triggers, can lead to the development of type 1 diabetes. Certain genes, including those in the HLA region, are known to increase susceptibility to the disease.
Choice C reason: In type 1 diabetes, the pancreas is indeed completely unable to produce insulin. This is due to an autoimmune attack on the beta cells of the pancreas, which are responsible for insulin production. Without insulin, the body cannot regulate blood glucose levels, leading to hyperglycemia and the need for exogenous insulin administration.
Choice D reason: Type 1 diabetes often has an acute onset, particularly in children and young adults. Symptoms can develop rapidly over a few days to weeks, including increased thirst, frequent urination, unintended weight loss, and severe fatigue. This acute presentation is a hallmark of the disease and contrasts with the more gradual onset seen in type 2 diabetes.
