What is glucose reading like with the Dawn Phenomenon?
One triggers insulin resistance and the release of glucose from the liver.
One is caused by the release of certain hormones.
Occurs between 4 a.m. and 9 a.m with hyperglycemia.
One is characterized by hyperglycemia that is not triggered by overnight hypoglycemia.
The Correct Answer is D
Choice A reason: This statement is partially correct but does not fully address the question about glucose readings. The Dawn Phenomenon involves an increase in blood glucose levels in the early morning due to the release of counter-regulatory hormones (like cortisol and growth hormone) that increase insulin resistance and stimulate glucose release from the liver.
Choice B reason: This statement is true but incomplete. The Dawn Phenomenon is indeed caused by the release of certain hormones, but this option does not specify the timing or the glucose readings.
Choice C reason: While the hyperglycemia associated with the Dawn Phenomenon does typically occur between 4 a.m. and 9 a.m., this option does not fully describe the nature of the glucose readings. It is more important to note that the hyperglycemia is not due to overnight hypoglycemia.
Choice D reason: This statement accurately describes the Dawn Phenomenon. It is characterized by morning hyperglycemia that is not caused by overnight hypoglycemia. Instead, it is due to the body's natural release of counter-regulatory hormones, which increase blood glucose levels during the early morning hours.

Correct Answer is C
Explanation
Choice A reason: Reversible deviant cells do not accurately describe neoplasia. Neoplasia involves the uncontrolled and irreversible growth of abnormal cells. While some deviant cell changes can be reversible, neoplasia specifically refers to irreversible changes that lead to tumor formation.
Choice B reason: Neoplasia does not adhere to the genetic controls placed on cellular proliferation and differentiation. In fact, the hallmark of neoplasia is the loss of these regulatory mechanisms, leading to uncontrolled cell growth and differentiation.
Choice C reason: Neoplasia indeed alters cellular proliferation and differentiation. This alteration is due to genetic mutations and other changes that lead to the loss of normal growth control. The result is the formation of tumors, which can be benign or malignant.
Choice D reason: Controlled and regulated cells do not describe neoplasia. Neoplastic cells grow and proliferate without the normal regulatory signals that control cell growth and differentiation. This uncontrolled growth is what characterizes neoplasia.
Correct Answer is B
Explanation
Choice A reason: Oliguria refers to the production of abnormally small amounts of urine. While it can occur in dehydration, it does not specifically indicate concentrated, dark, strong-smelling urine.
Choice B reason: Dehydration often leads to concentrated, dark, strong-smelling urine. When the body is dehydrated, the kidneys conserve water, resulting in less urine that is more concentrated with waste products, giving it a darker color and stronger smell.
Choice C reason: Increased fluid volume would typically result in dilute urine, which is pale and has a less strong odor. Therefore, it is not associated with concentrated, dark, strong-smelling urine.
Choice D reason: Urinary retention is the inability to empty the bladder completely. While it can lead to various symptoms, it is not specifically associated with concentrated, dark, strong-smelling urine.
