Hyperglycemic Hyperosmolar Nonketoic (HHNK) is an acute complication of:

Choice A reason: CA125, also known as Cancer Antigen 125, is a protein that is often elevated in ovarian cancer. It is used as a tumor marker to monitor treatment response and detect recurrence in patients with ovarian cancer. While CA125 can also be elevated in other conditions, it is most commonly associated with ovarian cancer and is a valuable tool in the management of this disease.

Choice B reason: H&H levels refer to hemoglobin and hematocrit levels, which are measures of red blood cells in the blood. While these levels can provide important information about a patient's overall health and can be affected by various conditions, they are not specific tumor markers used to detect or monitor cancer.

Choice C reason: Vitamin D levels are important for bone health and overall well-being, but they are not used as tumor markers. Vitamin D deficiency or excess can have various health implications, but it does not provide specific information about the presence or progression of cancer.

Choice D reason: Amylase levels are enzymes that help digest carbohydrates. Elevated amylase levels can indicate pancreatic issues, such as pancreatitis, but they are not used as tumor markers for cancer detection or monitoring. Amylase levels are more relevant to gastrointestinal and pancreatic health rather than oncology.

Choice A reason: This explanation is not correct. The reason why oral medications are not used for type 1 diabetes is not related to the child's ability to take the entire dose. The primary issue is the nature of insulin and how it must be administered.

Choice B reason: This statement is incorrect. The use of insulin injections is not based on age but on the type of diabetes. Type 1 diabetes requires insulin therapy regardless of the patient's age.

Choice C reason: Insulin is a protein that, if taken orally, would be broken down by the digestive enzymes in the gastrointestinal tract, rendering it ineffective. For this reason, insulin must be administered through subcutaneous injections to ensure it reaches the bloodstream intact and can effectively regulate blood glucose levels.
