Individuals with diabetes, a minor injury to the foot can cause major complications due to:
Increased WBC in the blood.
Edema to the tissues
Increase blood flow by giving more oxygen to the tissues.
Decreased blood flow to the tissues causing gangrene.
The Correct Answer is D
Choice A reason: While white blood cells (WBC) are essential for fighting infections, increased WBCs in the blood is not the reason why a minor injury can cause major complications in individuals with diabetes. In fact, diabetes can impair the function of WBCs, making it harder to fight infections.
Choice B reason: Edema, or swelling, can occur in individuals with diabetes, especially in the lower extremities. However, it is not the primary reason why minor injuries can lead to severe complications. Edema can contribute to discomfort and further complications, but it is not the root cause.
Choice C reason: Increased blood flow and oxygen delivery to tissues would generally be beneficial for healing. However, individuals with diabetes often have impaired blood flow, not increased blood flow. This impairment can hinder the healing process and lead to complications.
Choice D reason: The major reason why a minor injury can cause significant complications in individuals with diabetes is due to decreased blood flow to the tissues. Diabetes can cause damage to blood vessels and nerves (peripheral neuropathy), leading to poor circulation and a reduced ability to sense injuries. This decreased blood flow can prevent adequate delivery of oxygen and nutrients to the tissues, leading to slow healing, increased risk of infection, and in severe cases, gangrene (tissue death). Without proper blood flow, even minor injuries can become serious and may require medical intervention, including possible amputation to prevent the spread of infection.

Correct Answer is A
Explanation
Choice A reason: Peristalsis is the process by which smooth muscle fibers in the walls of the ureters contract rhythmically to propel urine from the kidneys to the bladder. This coordinated movement involves a wave-like series of contractions and relaxations, ensuring that urine is efficiently transported along the ureters, even against gravity. Peristalsis is a crucial mechanism for maintaining the flow of urine and preventing backflow into the kidneys.
Choice B reason: Mass movement refers to strong, coordinated contractions in the colon that move fecal matter toward the rectum. This process is associated with the large intestine and is not involved in the movement of urine through the ureters.
Choice C reason: Segmental contractions are localized contractions in the intestines that help mix and propel intestinal contents. They are not the primary mechanism for moving urine through the ureters.
Choice D reason: Tetany refers to involuntary muscle spasms or contractions, usually caused by low calcium levels or other electrolyte imbalances. It is not a normal physiological process for propelling urine through the ureters.
Correct Answer is D
Explanation
Choice A reason: Lispro (Insulin lispro) does not primarily act to reduce insulin resistance. Instead, it is a rapid-acting insulin analog used to manage blood glucose levels in people with diabetes.
Choice B reason: Lispro does not prevent the formation of glucose. Its main function is to help control blood sugar levels by replacing the insulin that the body is not producing enough of.
Choice C reason: Lispro does not decrease the body's need for glucose in body cells. Instead, it helps facilitate the uptake of glucose into cells by mimicking the action of natural insulin.
Choice D reason: Lispro acts as an insulin replacement. It is a fast-acting insulin analog that helps control blood sugar levels by mimicking the body's natural insulin, which is essential for the metabolism of glucose.
