Individuals with diabetes are also at increased risk for developing infection due to hyperglycemia related to microvascular, macrovascular, and neuropathic complications due to:
Excess protein in the blood provides an optimal environment for some pathogens, allowing rapid proliferation.
Excess glucose in blood provides an optimal environment for some pathogens, allowing rapid proliferation.
They produce less White Blood cells.
White Blood Cell destruction and high levels of glycosylated hemoglobin prevent release of oxygen to the tissues.
The Correct Answer is B
Choice A reason: While protein metabolism can be affected in diabetes, excess protein in the blood is not the primary mechanism increasing infection risk. Pathogens generally thrive more in high-glucose environments rather than high-protein conditions.
Choice B reason: Excess glucose in the blood creates an optimal environment for many pathogens to proliferate rapidly. High blood sugar levels weaken the immune system by impairing the function of white blood cells, making it harder for the body to fight off infections. This is particularly significant in the microvascular and macrovascular systems where the blood vessels can become damaged, further compromising immune response.
Choice C reason: Diabetic individuals do not necessarily produce fewer white blood cells. However, the functionality of these cells can be impaired by hyperglycemia, reducing their ability to fight off infections effectively.
Choice D reason: While high levels of glycosylated hemoglobin (HbA1c) indicate poor blood sugar control over a long period, the destruction of white blood cells is not the primary reason for increased infection risk. The issue lies more with the impaired function of white blood cells and the conducive environment that excess glucose provides for pathogens.

Correct Answer is B
Explanation
Choice A reason: Running, while excellent for cardiovascular fitness and overall muscle strength, does not specifically target the pelvic floor muscles. These muscles require specific exercises to strengthen them effectively.
Choice B reason: Kegel exercises are specifically designed to strengthen the pelvic floor muscles. These exercises involve repeatedly contracting and relaxing the muscles that form part of the pelvic floor, which supports the bladder, bowel, and uterus. Regular practice of Kegel exercises can improve bladder control and overall pelvic health.
Choice C reason: Holding urine for extended periods of time is not a recommended way to strengthen pelvic muscles. In fact, this practice can lead to urinary tract infections and bladder problems. It is important to empty the bladder regularly to maintain urinary health.
Choice D reason: Weight-bearing exercises are beneficial for bone health and overall muscle strength but do not specifically target the pelvic floor muscles. Specific exercises, like Kegels, are needed to strengthen the pelvic floor effectively.
Correct Answer is A
Explanation
Choice A reason: Neuropathy, particularly diabetic neuropathy, is often caused by the thickening, sclerosis (hardening), obstruction, and ischemia (reduced blood flow) of the small blood vessels that supply the nerves (vasa nervorum). This can lead to nerve degeneration, delayed nerve conduction, and impaired sensory function. Over time, high blood glucose levels can damage these small blood vessels, leading to neuropathy.
Choice B reason: While hyperglycemia (high blood glucose levels) is a major factor in the development of diabetic neuropathy, it is the resulting damage to the blood vessels supplying the nerves that directly causes the nerve degeneration and delayed conduction.
Choice C reason: Thickening of blood is not a direct cause of neuropathy. Neuropathy is more directly related to the damage and obstruction of the small blood vessels that supply the nerves.
Choice D reason: Hypoglycemia (low blood glucose levels) does not cause neuropathy. In fact, the acute effects of hypoglycemia are typically neurological symptoms such as confusion, seizures, and loss of consciousness. Chronic nerve damage, as seen in neuropathy, is usually due to prolonged hyperglycemia and its effects on blood vessels.
