pH 7.53 and low CO2 (32) indicate respiratory alkalosis from hyperventilation, not typical in chest trauma where breathing is impaired. HCO3 (24) is normal, showing no compensation yet, misaligning with trauma physiology.

pH 7.49 and low CO2 (30) suggest respiratory alkalosis, while low HCO3 (14) indicates metabolic compensation. This doesn’t match chest trauma’s ventilatory restriction, which elevates CO2 instead.

pH 7.26, CO2 (45), and low HCO3 (18) show mixed acidosis. Chest trauma primarily causes respiratory acidosis from CO2 retention, not a significant metabolic drop acutely, making this less precise.

Fluid restriction doesn’t address hyperkalemia (6.4 mEq/L); it may concentrate potassium further, worsening the condition, as it’s unrelated to potassium excretion or shifting in this scenario.

Neomycin, an antibiotic, reduces gut bacteria but isn’t used for hyperkalemia. It has no direct effect on potassium levels, making it irrelevant for this lab finding.

Sodium chloride and furosemide dilute and excrete potassium via urine, but Kayexalate is preferred for rapid gut-based removal when potassium is critically high (6.4 mEq/L).

Heat intolerance occurs in hyperthyroidism due to increased metabolism raising body temperature. Myxedema causes cold intolerance from slowed metabolism, making this finding unlikely.

Tachycardia is a hyperthyroid symptom from excess thyroid hormone speeding heart rate. Myxedema leads to bradycardia as metabolism and cardiac activity decrease significantly.

Diarrhea aligns with hyperthyroidism’s accelerated gut motility. Myxedema causes constipation from slowed metabolism reducing peristalsis, so diarrhea contradicts this condition’s physiology.

Prednisone, a corticosteroid, suppresses inflammation and immune response in lupus, reducing joint pain and organ damage from autoantibody activity, making it a standard treatment.

Hydroxychloroquine modulates immunity and reduces lupus flares by stabilizing lysosomes and decreasing autoantibody production, directly addressing its autoimmune pathology.

Methotrexate, an immunosuppressant, inhibits folate metabolism, curbing immune cell proliferation in lupus, effectively managing severe symptoms like arthritis or organ involvement.

Heparin prevents clotting during dialysis but doesn’t reduce hemoglobin or hematocrit directly. It’s not a primary cause of anemia in renal failure, unlike erythropoietin deficiency.

Minor blood loss occurs in dialysis, but it’s not the primary reason for chronic anemia. Erythropoietin deficiency from renal failure has a greater impact on counts.

Poor protein intake affects overall health but isn’t the main driver of anemia in renal failure. Erythropoietin loss from kidney dysfunction is the dominant factor.

Radioactive iodine treats hyperthyroidism by destroying thyroid tissue, reducing hormone production. It’s contraindicated in hypothyroidism, where hormone replacement is needed instead.

Sumatriptan, a serotonin agonist, treats migraines by constricting blood vessels. It has no role in hypothyroidism, which requires thyroid hormone supplementation.

Levofloxacin, an antibiotic, fights bacterial infections but doesn’t address hypothyroidism’s hormonal deficiency, making it irrelevant to this condition’s treatment.

Diaphoresis (sweating) occurs in hyperthyroidism from excess metabolism raising body heat. Hypothyroidism causes dry skin and cold intolerance, not sweating.

Exophthalmos, bulging eyes, results from Graves’ disease in hyperthyroidism due to orbital inflammation. Hypothyroidism doesn’t affect eye protrusion, making this unlikely.

Palpitations stem from hyperthyroidism’s increased heart rate via excess thyroid hormone. Hypothyroidism slows heart rate, leading to bradycardia, not palpitations.

Levothyroxine takes weeks to normalize metabolism in hypothyroidism as T4 converts to T3 gradually, so immediate symptom relief isn’t accurate or expected.

Levothyroxine supplements, not decreases, thyroxine in hypothyroidism. Decreasing overproduction applies to hyperthyroidism treatments like antithyroid drugs, not this condition.

Hypothyroidism requires lifelong levothyroxine since the thyroid can’t produce hormone. Stopping when symptoms resolve risks recurrence, making this advice incorrect.

Bedrest post-liver biopsy prevents bleeding by reducing movement and pressure on the puncture site, a standard protocol, so this statement is correct.

Stopping warfarin, an anticoagulant, a week prior reduces bleeding risk during biopsy, a necessary step, making this statement accurate and appropriate.

Liver biopsy diagnoses cancer by examining tissue for malignant cells, confirming the procedure’s purpose, so this statement aligns with clinical intent.
