A nurse is teaching a client who has multiple sclerosis. Which of the following instructions should the nurse include in the teaching?

Rationale:
A. Initiate fibrinolytic therapy: Fibrinolytic therapy, such as tissue plasminogen activator (tPA), is most effective when administered within a 3- to 4.5-hour window from the onset of ischemic stroke symptoms. Early administration can dissolve the clot, restore cerebral blood flow, and improve neurological outcomes.

B. Place the client in a supine position: Clients with ischemic stroke are usually positioned with the head of the bed elevated 15–30 degrees unless contraindicated. Supine positioning can increase intracranial pressure and risk aspiration, which may worsen neurological status.

C. Prepare the client for a chest x-ray: A chest x-ray is not a priority in acute ischemic stroke management. Immediate neuroimaging, typically a CT scan, is required to differentiate ischemic from hemorrhagic stroke before initiating fibrinolytic therapy.

D. Insert an indwelling urinary catheter: Inserting a catheter is not indicated as an initial intervention for acute stroke unless the client is unable to void or requires strict output monitoring. Priority actions focus on neuroprotection and reperfusion therapy.

Rationale:
A. "Add salt to season foods.": Adding salt can irritate oral mucosa, especially in clients with AIDS who often develop stomatitis or oral candidiasis. Salty foods worsen pain and delay healing of mucosal lesions, so mild, bland foods are preferred.

B. "Eat foods served at hot temperatures.": Hot foods increase discomfort and can further damage already inflamed oral tissues. Clients should instead consume cool or room-temperature foods to soothe irritation and promote better oral intake.

C. "Rinse your mouth with an alcohol-based mouthwash.": Alcohol-based mouthwashes dry and irritate the mucous membranes, worsening oral pain and increasing the risk of bleeding or infection. Nonalcoholic rinses, such as saline or baking soda solutions, are safer alternatives.

D. "Use ice chips to numb your mouth.": Sucking on ice chips provides local numbing and temporary pain relief, allowing the client to eat and drink more comfortably. This simple intervention also helps keep the oral mucosa moist and reduces inflammation.
