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 D
Explanation
Choice A reason: The neck is the most common site where individuals with Hodgkin Lymphoma (HL) present with nontender enlarged lymph nodes. These lymph nodes are typically firm and rubbery in texture. The cervical lymph nodes are often affected first in HL, making the neck a primary area of concern for this type of lymphoma. Early detection and biopsy of these lymph nodes can help in diagnosing HL.
Choice B reason: While the abdomen can be involved in Hodgkin Lymphoma, it is not the most common initial presentation site. Involvement of the abdominal lymph nodes typically occurs at later stages of the disease. Enlarged lymph nodes in the abdomen can be detected through imaging studies but are less accessible for physical examination compared to those in the neck.
Choice C reason: The kidney is not a typical site for lymph node involvement in Hodgkin Lymphoma. HL primarily affects the lymphatic system, including lymph nodes, spleen, and other lymphoid tissues. Direct involvement of the kidney is rare and usually occurs in advanced stages of the disease.
Choice D reason: The spleen is a lymphoid organ that can be involved in Hodgkin Lymphoma, especially in more advanced stages. However, it is not the primary site where nontender enlarged lymph nodes are first detected. Enlargement of the spleen (splenomegaly) can occur due to the spread of HL, but the initial presentation is usually in the lymph nodes of the neck.
Correct Answer is D
Explanation
Choice A reason: The heart is not directly affected by urinary stasis and subsequent bacterial growth. While severe infections can potentially lead to systemic issues, the primary concern with urinary stasis is the local and ascending infection within the urinary tract.
Choice B reason: The ears are not involved in the urinary system, and stasis of urine does not lead to infections in the ears. Ear infections are typically caused by different pathogens and mechanisms unrelated to urinary stasis.
Choice C reason: The lungs are also not affected by urinary stasis. Lung infections, such as pneumonia, are usually caused by respiratory pathogens and not by bacteria originating from the urinary tract.
Choice D reason: The kidneys are the correct answer because stasis of urine in the bladder can lead to bacterial growth and infection. When urine remains in the bladder for an extended period, it creates an environment conducive to bacterial proliferation. These bacteria can ascend the urinary tract, reaching the ureters and kidneys, causing infections such as pyelonephritis. Kidney infections are serious and can lead to complications if not treated promptly.
