A nurse is teaching a group of teenage clients about the use of condoms for the prevention of sexually transmitted infections (STIs). Which of the following statements should the nurse include in the teaching?

Choice A reason:
Decreased hemoglobin (Hgb) levels can be indicative of anemia or blood loss, but they are not typically associated with fluid volume deficit. In cases of fluid volume deficit, the Hgb concentration may actually appear elevated due to hemoconcentration as the plasma volume decreases.

Choice B reason:
Increased blood urea nitrogen (BUN) levels are expected in a fluid volume deficit because as the blood volume decreases, the concentration of solutes like urea can increase. This is often due to decreased renal perfusion and subsequent reduced renal function, leading to less urea being excreted through the kidneys.

Choice C reason:
Increased urine ketones are typically associated with diabetic ketoacidosis or starvation, not directly with fluid volume deficit. Ketones are produced when the body breaks down fats for energy, which is not a process directly related to fluid volume status.

Choice D reason:
Decreased urine specific gravity would not be expected in fluid volume deficit; in fact, one would expect the opposite. Specific gravity measures the kidney's ability to concentrate urine. In fluid volume deficit, the urine specific gravity would likely be increased as the body attempts to conserve water.

Choice A reason:
While autoimmune disorders are associated with type 1 diabetes, where the immune system attacks the pancreas, they are not typically a direct risk factor for type 2 diabetes. Type 2 diabetes is more closely related to lifestyle factors and insulin resistance.

Choice B reason:
A 40-year-old client with hypoglycemia may be at risk for developing type 2 diabetes. Hypoglycemia can be a sign of pre-diabetes or insulin resistance, where the body's response to insulin is not as effective, leading to fluctuations in blood sugar levels. As individuals age, their risk for type 2 diabetes increases, particularly if they have other risk factors such as a sedentary lifestyle, overweight, or a family history of diabetes.

Choice C reason:
Lack of sleep can contribute to the development of type 2 diabetes by affecting the body's ability to regulate glucose and by increasing insulin resistance. However, without additional risk factors, it is not as strong a predictor of type 2 diabetes as the presence of hypoglycemia or other metabolic conditions.

Choice D reason:
Having never given birth is not a recognized risk factor for type 2 diabetes. While gestational diabetes is a risk factor for developing type 2 diabetes later in life, the absence of pregnancy does not increase the risk.
