A nurse is assessing a client who has hyperthyroidism. Which of the following findings should the nurse expect?

Choice A reason: Diabetes does not typically cause bruising or nosebleeds. It involves glucose dysregulation, leading to symptoms like polyuria or neuropathy. Bruising and bleeding are unrelated to diabetes pathophysiology, making this an incorrect condition for the client’s symptoms.

Choice B reason: Pancreatitis, often linked to alcohol use, causes abdominal pain and elevated enzymes but not primarily bruising or nosebleeds. These symptoms are more related to liver dysfunction, making pancreatitis an incorrect diagnosis for the client’s bleeding tendencies.

Choice C reason: Hepatitis A causes acute liver inflammation with symptoms like jaundice and fatigue but is less associated with chronic alcohol use or bleeding tendencies. Bruising and nosebleeds suggest chronic liver damage, making hepatitis A less likely than cirrhosis.

Choice D reason: Cirrhosis, common in alcohol use disorder, causes bruising and nosebleeds due to impaired liver synthesis of clotting factors and thrombocytopenia from portal hypertension. These hematologic abnormalities, coupled with alcohol history, make cirrhosis the most likely condition for the client’s symptoms.

Choice A reason: Initiating 3% sodium chloride infusion is appropriate for severe hyponatremia (118 mEq/L) in SIADH, as hypertonic saline corrects low serum sodium by increasing extracellular sodium concentration. This addresses water retention from excess ADH, preventing neurological complications like seizures, making it a key intervention.

Choice B reason: Administering tolvaptan, a vasopressin receptor antagonist, is effective in SIADH, as it promotes water excretion, increasing urine output and correcting hyponatremia. By blocking ADH action, it reduces fluid retention, making it a suitable intervention for severe cases with low sodium levels.

Choice C reason: Administering lactulose is used for hepatic encephalopathy to reduce ammonia, not for SIADH’s hyponatremia. It does not address electrolyte imbalances caused by water retention, making it irrelevant for correcting sodium levels or managing SIADH’s pathophysiology.

Choice D reason: Maintaining seizure precautions is critical in SIADH with severe hyponatremia (118 mEq/L), as low sodium disrupts neuronal membrane stability, increasing seizure risk. Precautions like padded rails and anticonvulsants protect the client, making this a necessary intervention for safety.

Choice E reason: Administering a 3-liter 5% dextrose water bolus is contraindicated in SIADH, as it adds free water, worsening hyponatremia by further diluting serum sodium. Hypertonic saline or fluid restriction is needed, making this an inappropriate and potentially harmful intervention.
