A nurse is preparing to administer lansoprazole 30 mg PO daily to a client. The amount available is lansoprazole 10 mg per tablet. How many tablets should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Step 1: Convert the client’s weight from pounds to kilograms. 198 lb ÷ 2.2 = 90 kg

Result: 90 kg

Step 2: Calculate the total daily dose of vancomycin. 15 mg × 90 kg = 1350 mg/day

Result: 1350 mg/day

Step 3: Divide the total daily dose by 2 to get the dose per administration (since it is given every 12 hours). 1350 mg/day ÷ 2 = 675 mg

Result: 675 mg

Final Answer: The nurse should administer 675 mg of vancomycin with each dose.

Choice A reason: Drive the client to the nearest emergency department

While it might seem helpful to drive the client to the nearest emergency department, it is not the best course of action. The symptoms described—right-sided weakness and slurred speech—are indicative of a possible stroke. Time is critical in stroke management, and emergency services can provide immediate medical intervention and transport to a stroke center, which is essential for the best possible outcome.

Choice B reason: Call emergency services

Calling emergency services is the most appropriate action. The client is exhibiting signs of a stroke, and rapid medical intervention is crucial. Emergency medical services (EMS) can begin treatment en route to the hospital and ensure the client is taken to a facility equipped to handle strokes. This action maximizes the chances of a positive outcome by minimizing delays in treatment.

Choice C reason: Find a location for the client to sit

Finding a location for the client to sit might provide temporary comfort, but it does not address the urgent need for medical intervention. In the case of a suspected stroke, immediate action is necessary to prevent further damage. Sitting the client down does not provide the critical care needed in this situation.

Choice D reason: Obtain the telephone number of the client’s provider

Obtaining the telephone number of the client’s provider is not the priority in an emergency situation like this. While it might be useful information later, the immediate need is to get the client to a hospital as quickly as possible. Contacting the provider can be done after emergency services have been called.
