NURSING & CLINICAL LABORATORY GUIDE

Staff Nurse

A staff nurse is a nurse employed in a clinical healthcare setting who provides direct patient care as part of a multidisciplinary healthcare team. “Staff nurse” is primarily a job role or employment designation, rather than a separate universal nursing license or advanced practice credential.

What Is a Staff Nurse?

A staff nurse is a licensed nurse employed in a healthcare setting who provides direct patient care as a member of a multidisciplinary clinical team. The term “staff nurse” refers primarily to a job role or employment designation, rather than a specific nursing license or credential.

Staff nurses may be Registered Nurses (RNs), Licensed Practical Nurses (LPNs), or Licensed Vocational Nurses (LVNs), depending on the healthcare system, job requirements, and applicable regulations. Their responsibilities include patient assessment, medication administration, monitoring patient condition, coordinating care, and collaborating with physicians and other healthcare professionals.

“Staff nurse” describes the employment role rather than automatically defining the professional credential. Scope of practice depends on the nurse’s license, jurisdiction, and institutional policies.

Staff Nurse Daily Workflow

Shift Handoff → Patient Assessment → Care Planning → Medication/Treatment → Monitoring → Lab/Diagnostic Review → Reassessment → Documentation → Handoff

Staff nurses prioritize patients according to clinical condition and urgency, using clinical judgment to determine the order and timing of care activities.

Patient Assessment

Staff nurses perform assessments including:

Initial assessment – Comprehensive evaluation on admission.
Focused assessment – Targeted evaluation for specific concerns.
Vital signs – Temperature, pulse, respiration, blood pressure, SpO₂.
Pain assessment – Using validated pain scales.
Neurologic observations – Level of consciousness, pupil response.
Respiratory assessment – Lung sounds, effort, oxygenation.
Cardiovascular assessment – Heart sounds, perfusion, edema.
Skin assessment – Integrity, wounds, pressure areas.
Intake and output – Fluid balance monitoring.
Mobility and fall-risk – Safety assessment.
Mental and emotional status – Psychological assessment.
Changes from baseline – Recognizing deterioration or improvement.

Assessment responsibilities vary according to the nurse’s role, setting, and patient condition.

Staff Nurse and Laboratory Testing

Staff nurses interact with laboratory testing throughout the patient-care process:

Recognizing relevance – Identifying when laboratory information is relevant to patient care.
Reviewing results – Checking available laboratory results.
Identifying abnormal results – Recognizing abnormal or critical values.
Communicating findings – Sharing significant results with the healthcare team.
Monitoring trends – Tracking laboratory values over time.
Preparing patients – Explaining tests and ensuring patient readiness.
Collecting specimens – When authorized and trained.
Patient identification – Verifying patient identity for tests and specimens.
Specimen labeling – Ensuring correct specimen identification.
Specimen handling – Proper storage and transport.
Infection control – Following infection prevention procedures.
Documentation – Recording laboratory-related care.

Important: Nurses generally do not independently diagnose a disease solely from a laboratory result. Laboratory findings are interpreted in the context of the patient’s clinical condition and the broader healthcare team.
