A client is admitted to the hospital with symptoms consistent with a right hemisphere stroke. Which neurovascular assessment requires immediate intervention by the nurse?

Choice A reason: Persistent pain after Herpes zoster suggests postherpetic neuralgia (PHN), a neuropathic condition from varicella-zoster virus damaging sensory nerves. Assessing pain intensity, location, and characteristics guides treatment with analgesics or anticonvulsants like gabapentin. This step differentiates PHN from other causes, ensuring targeted therapy to alleviate nerve pain and improve quality of life.

Choice B reason: Checking shingles vaccination status is irrelevant for current pain, as the client already had Herpes zoster. Vaccination prevents initial infection but does not treat PHN, which results from nerve damage during active infection. Pain assessment is critical to address neuropathic symptoms caused by viral-induced sensory nerve dysfunction, making this less urgent.

Choice C reason: A mental status exam evaluates cognition but is not indicated for PHN, a physiological condition from nerve damage, not a cognitive issue. Pain is neuropathic, driven by damaged sensory neurons, not psychological factors. Assessing pain directly addresses the client’s complaint, guiding treatment for nerve-related discomfort, making this action inappropriate.

Choice D reason: Teaching about phantom pain is incorrect, as phantom pain occurs post-amputation, not after shingles. PHN involves persistent nerve pain in the affected dermatome due to viral nerve damage. Misdiagnosing this could delay proper management, as pain assessment is needed to confirm PHN and initiate therapies like gabapentin, not phantom pain education.

Choice A reason: Acetaminophen is hepatotoxic, metabolized by the liver via cytochrome P450 to NAPQI, which depletes glutathione, causing necrosis in hepatitis. A compromised liver from alcohol or viral hepatitis increases toxicity risk, even at standard doses. Contacting the provider ensures safer analgesics, preventing further liver damage in this high-risk client.

Choice B reason: Olanzapine, an antipsychotic, manages schizophrenia by blocking dopamine D2 receptors. It is metabolized by the liver but has low hepatotoxicity risk compared to acetaminophen in hepatitis. No immediate contraindication exists, as it controls psychosis without significantly worsening liver function, making it safe to administer without delay.

Choice C reason: Thiamine (vitamin B1) is essential in hepatitis, particularly with alcohol abuse, preventing Wernicke’s encephalopathy from deficient glucose metabolism. It is liver-safe and beneficial, supporting neurological function without toxicity. Administering thiamine is appropriate, making it unnecessary to contact the provider before implementation.

Choice D reason: Ondansetron, an antiemetic, controls nausea in hepatitis via serotonin 5-HT3 receptor blockade. It is metabolized by the liver but has minimal hepatotoxicity, safe in liver disease. No contraindication exists, as it alleviates symptoms without worsening hepatitis, unlike acetaminophen, which poses significant liver risk.
