Which complication(s) may occur due to a spinal cord injury? (Select all that apply)

Choice A reason: SIADH causes excessive antidiuretic hormone, leading to water retention and dilutional hyponatremia. Low serum sodium results from increased water reabsorption in the kidneys, causing neurological symptoms, making this the correct manifestation.

Choice B reason: Hyperkalemia is not associated with SIADH, which affects water balance, not potassium. Potassium imbalances occur in adrenal or renal disorders, not SIADH’s water retention mechanism, making this choice incorrect.

Choice C reason: Hyperglycemia is unrelated to SIADH, which involves water retention and sodium dilution. Glucose levels are affected by diabetes, not antidiuretic hormone dysfunction, making this choice incorrect for SIADH manifestations.

Choice D reason: Hypertension may occur in SIADH due to fluid overload, but it is not the primary manifestation. Hyponatremia is more specific, as water retention directly dilutes sodium, making this choice incorrect.

Choice A reason: Hypoparathyroidism causes hypocalcemia due to low parathyroid hormone, reducing calcium levels. Low calcium leads to neuromuscular excitability, causing muscle cramps and tetany, a hallmark symptom, making this the correct manifestation of hypoparathyroidism.

Choice B reason: Increased urination is associated with diabetes or hypercalcemia, not hypoparathyroidism. Hypoparathyroidism causes hypocalcemia, which does not directly affect urine output, making this choice incorrect for the condition’s manifestations.

Choice C reason: Weight gain is not a direct manifestation of hypoparathyroidism. Hypocalcemia affects neuromuscular function, not metabolism or weight. Hypothyroidism may cause weight gain, but hypoparathyroidism does not, making this choice incorrect.

Choice D reason: Hypertension is not typical of hypoparathyroidism, which causes hypocalcemia and neuromuscular symptoms. Hyperparathyroidism or other conditions may cause hypertension via hypercalcemia, but hypoparathyroidism does not, making this choice incorrect.
