Karen Davenport, APN, ACNP-BC in Chattanooga: Adult Internal Medicine and Hospital-Based Care
Karen Davenport is an acute care nurse practitioner specializing in internal medicine for adult patients in a hospital and inpatient-focused setting. Rather than operating a standalone private practice, she works within a clinical care structure where her scope covers the diagnosis and management of acute and chronic medical conditions typical of internal medicine, including hypertension, diabetes, infections, and acute exacerbations of chronic illness.
What she does
An ACNP-BC (Acute Care Nurse Practitioner, Board Certified) is a registered nurse with advanced training, graduate-level credentials, and independent diagnostic and treatment authority within her scope. In internal medicine, that means ordering labs and imaging, prescribing medications, managing acute hospital admissions, and coordinating ongoing care for adults with complex or evolving medical problems. ACNPs in hospital settings often manage patients on acute care units, work alongside attending physicians, and handle the continuity of care between admission and discharge. Her credentials reflect certification by the American Nurses Credentialing Center, a standard that requires continued education and periodic recertification.
Services and when to see her
Davenport handles evaluation and management of acute medical illness, exacerbations of chronic conditions, medication adjustments, and diagnostic workup of unexplained symptoms in hospitalized or acute-care settings. Patients typically access her care through referral from an emergency department, a scheduled hospital admission for a known condition, or transfer within a hospital system. She does not manage routine preventive care or schedule independent outpatient appointments the way a primary-care office does; her work takes place in the hospital environment where acute medical problems are treated.
If you are looking for a primary-care doctor for annual checkups, chronic disease management in an office, or routine monitoring, Davenport's role is not the right fit. If you are hospitalized or referred for acute internal medicine assessment and management, her credentials and hospital-based practice are where her expertise applies.
How hospital-based internal medicine differs from office-based primary care
Hospital-based acute-care practitioners like Davenport operate in a different workflow from office-based internists or primary-care providers in Chattanooga. Office-based doctors manage preventive care, establish long-term relationships, and see patients for routine follow-ups over months or years. Hospital-based ACNPs focus on acute, time-sensitive medical problems and coordinate discharge planning. The two roles often overlap when a primary-care doctor refers a patient to the hospital for workup or admission; the hospital ACNP takes over acute management, then the patient returns to their primary doctor afterward.
Chattanooga's hospital systems, including Erlanger Health System and Parkridge Medical Center, employ ACNPs like Davenport to staff acute-care units and handle the caseload during hospitalization. If you are hospitalized, knowing whether your care team includes an ACNP helps you understand that advanced-practice nurses manage a portion of your direct care alongside or under the supervision of attending physicians.
First visit and what to expect
Access to Davenport's care begins with a hospital visit or a referral from an emergency department or primary-care provider. You do not schedule an independent office visit; instead, you meet her during an inpatient admission or acute-care encounter. On arrival, your medical history, current medications, and reason for admission are documented. She will perform a physical exam, order relevant laboratory or imaging studies, review results, and develop a management plan. If you are new to the hospital system, your insurance information and any known allergies or contraindications should be available in your hospital record.
If you are an established patient of Erlanger or Parkridge and are admitted, you may be assigned to a clinical team that includes her. If you are transferred between units or from an outside facility, hospital care coordinators can help clarify which provider or team will oversee your acute-medicine care.
Hours and logistics
Davenport works within hospital inpatient hours, meaning she is available during the hospital's 24-hour operation, though specific shift hours and on-call schedules are managed by her employer hospital system. Hospital-based care does not follow traditional office hours; patient access depends on admission status and the referral pathway into the hospital.
Parking and logistics depend on which Chattanooga hospital system provides her services. Erlanger Health System's main campus and Parkridge Medical Center both maintain visitor and patient parking. Verification of her current assignment, on-call schedule, or exact inpatient unit should be confirmed directly with the hospital's main line or admissions department, as staff assignments and clinical rotations change.
Why this matters for Chattanooga patients
Knowing the difference between office-based and hospital-based practitioners helps you navigate the right care at the right time. ACNPs like Davenport extend the capacity of hospital internal-medicine teams and ensure that acute medical illness receives timely, skilled assessment and management during the window when hospitalization is necessary. If you are hospitalized and want to know who is managing your acute medical care, ask your nurse or attending physician whether an ACNP is part of your care team.
