The nurse first clarifies with the provider that this medication is appropriate for this patient. The drug of choice for community-acquired pneumonia is either doxycycline or a macrolide like azithromycin. Patients with comorbidities may require ceftriaxone, but the maximum dose in patients with liver disease is 2,000 mg per day, not 4,000 mg. In fact, a dose of 4,000 mg per day is unusual in otherwise healthy patients. The nurse should then review laboratory test results to assess the appropriateness of therapy, confirm the client’s identity using at least two client identifiers, and explain the procedure to the client.
