What type of immunity does a person gain when they receive an infusion of antibodies for short-term protection?

Choice A reason: Hyperglycemia causes polyuria as high blood glucose exceeds renal reabsorption capacity, leading to osmotic diuresis. Excess glucose in urine draws water, increasing urine output, a classic diabetes symptom, making this a correct manifestation.

Choice B reason: Polyphagia, or increased hunger, occurs in hyperglycemia as cells cannot utilize glucose due to insulin deficiency or resistance, signaling energy deficit. The body craves food to compensate, making this a correct manifestation.

Choice C reason: Excessive thirst (polydipsia) results from hyperglycemia-induced polyuria, causing dehydration. The body signals thirst to replenish fluid loss from osmotic diuresis, a hallmark of diabetes, making this a correct manifestation.

Choice D reason: Photophobia, sensitivity to light, is not associated with hyperglycemia. It occurs in conditions like meningitis or migraines, not metabolic disturbances like diabetes, making this choice incorrect for hyperglycemia manifestations.

Choice E reason: Dysphagia, difficulty swallowing, is unrelated to hyperglycemia. It may occur in neurological or esophageal disorders, not as a direct result of high blood glucose, making this choice incorrect for hyperglycemia.

Choice A reason: Renal failure causes metabolic acidosis (low pH, low HCO3) due to impaired acid excretion and bicarbonate reabsorption. The low PaCO2 indicates respiratory compensation (hyperventilation) to reduce acidity, matching renal failure’s acid-base profile, making this the correct choice.

Choice B reason: This shows respiratory acidosis (low pH, high PaCO2) with normal HCO3, suggesting lung dysfunction, not renal failure. Renal failure causes metabolic acidosis due to acid retention, not CO2 accumulation, making this choice incorrect.

Choice C reason: This indicates respiratory alkalosis (high pH, low PaCO2) with low HCO3, suggesting hyperventilation, not renal failure. Renal failure leads to metabolic acidosis from acid accumulation, not respiratory changes, making this choice incorrect.

Choice D reason: This shows metabolic alkalosis (high pH, high HCO3), not typical of renal failure, which causes acidosis due to impaired acid excretion. The normal PaCO2 suggests no respiratory compensation, making this choice incorrect for renal failure.
