Neutropenia Management

Neutropenia severity is graded by the absolute neutrophil count (ANC). Each ANC range requires a specific level of protective precautions and nursing vigilance — from standard care at normal counts to full reverse isolation and emergency febrile neutropenia protocols at severe and profound levels.

Educational use only. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.

ANC formula: ANC = WBC × (% segs + % bands) ÷ 100. Always calculate from the differential, not the WBC alone.

ANC Range	Risk Level	Precautions	Nursing Actions
≥1,500/mm³ Normal	Normal	✦Standard precautions ✦Routine hand hygiene for all staff and visitors ✦No additional restrictions	✦Continue standard care ✦Educate patient about nadir timing (if on chemo: watch for counts to drop 7–14 days post-treatment) ✦Reinforce hand hygiene as ongoing habit
1,000–1,499/mm³ Mild Neutropenia	Slightly Elevated	✦Standard hand hygiene reinforcement ✦Avoid known sick contacts ✦Report fever ≥38°C immediately ✦Avoid elective invasive procedures	✦Educate patient and family on fever reporting and infection symptoms ✦Assess for early infection signs at each encounter ✦No rectal temperatures or rectal exams ✦Monitor for approaching nadir if post-chemo
500–999/mm³ Moderate Neutropenia	Moderate	✦All neutropenic precautions initiated ✦Avoid crowds and people with infections ✦No fresh flowers or live plants in room ✦Neutropenic diet (well-cooked foods only) ✦Hand hygiene for ALL persons entering room ✦Mask per institutional protocol	✦Private room if available ✦Monitor temperature q4h (or per protocol) ✦Assess for subtle infection signs: redness at IV sites, cough, dysuria, oral mucositis ✦Avoid unnecessary venipunctures and invasive procedures ✦No rectal temps, suppositories, or enemas ✦Document and report T ≥38°C immediately ✦Reinforce neutropenic diet with patient and family
<500/mm³ Severe Neutropenia	HIGH	✦Private room required ✦Strict hand hygiene — all visitors ✦Visitor screening — no ill visitors, no children under 12 (per policy) ✦No fresh flowers or plants ✦Neutropenic diet strictly enforced ✦HEPA filtration room if available ✦Mask for patient when leaving room ✦Limit invasive procedures to essential only	✦Temperature every 4 hours — report T ≥38°C (100.4°F) IMMEDIATELY ✦Febrile neutropenia protocol ready: blood cultures × 2 then IV antibiotics within 60 min ✦Central line assessment each shift (CLABSI risk elevated) ✦Oral assessment — mucositis and candida are common ✦Skin assessment — redness, warmth, breakdown at any site ✦Minimize blood draws — use existing CVAD when possible ✦Teach patient NOT to take aspirin or NSAIDs (mask fever) ✦G-CSF (filgrastim) per order — anticipate bone pain
<100/mm³ Profound Neutropenia (Agranulocytosis)	CRITICAL	✦All severe precautions PLUS: ✦Positive-pressure HEPA-filtered room ✦Strict reverse isolation protocols per institution ✦No fresh or raw foods of any type ✦Sterile or filtered water per institutional policy ✦Antifungal and antiviral prophylaxis per order ✦Minimal number of staff entering room	✦Continuous monitoring — vital signs q2–4h ✦Patient at extreme risk from any pathogen — bacteria, fungi, viruses ✦Common at this level: BMT/SCT patients — engraftment is goal ✦Watch for signs of invasive fungal infection: persistent fever on antibiotics, pulmonary infiltrates ✦Assess for CMV reactivation in BMT patients (retinitis, pneumonitis, colitis) ✦Strict central line care — replace with full barrier precautions ✦Nutritional support — patient often cannot eat due to mucositis; EN/TPN per order ✦Psychological support — extreme isolation is distressing

Febrile Neutropenia Emergency Protocol (ANC <500 + Fever)

Definition

Fever ≥38°C (100.4°F) for ≥1 hour OR ≥38.3°C (101°F) once, AND ANC <500/mm³ (or expected to fall below 500).

Time Targets

Blood cultures: within 30 minutes. IV antibiotics: within 60 minutes of identification. Delay = higher mortality.

!1. Notify provider immediately — treat with same urgency as sepsis

!2. Blood cultures × 2 sets (peripheral AND each central line lumen) BEFORE antibiotics

!3. Broad-spectrum IV antibiotics within 60 minutes — Pseudomonas coverage required (pip-tazo, cefepime, or meropenem)

!4. Additional cultures if indicated: urine, sputum, wound

!5. CBC, CMP, LFTs, LDH, chest X-ray

!6. Assess potential source: skin, oral mucosa, CVAD sites, perirectal area (palpation only — NO rectal exam)

!7. NO rectal temperatures, thermometers, or enemas in neutropenic patients

G-CSF Quick Reference (Colony-Stimulating Factors)

Drug	Duration	Key Nursing Point
Filgrastim (Neupogen)	Short-acting — daily SQ injection	Bone pain (marrow expansion) — treat with acetaminophen; NOT within 24 hrs of chemo
Pegfilgrastim (Neulasta)	Long-acting — once per cycle	On-body injector option; same bone pain and chemo timing restriction
Sargramostim (Leukine)	GM-CSF — used post-BMT	Watch for capillary leak: dyspnea, edema; fever and myalgia common

NCLEX Quick Recall

✦ANC <500 = severe neutropenia — maximum protective precautions

✦Fever + ANC <500 = febrile neutropenia = EMERGENCY — antibiotics within 60 minutes

✦Blood cultures BEFORE antibiotics — but do NOT delay antibiotics waiting for results

✦NO rectal temperatures, suppositories, or enemas — disrupts mucosal barrier → bacteremia

✦No fresh flowers or plants — Aspergillus and Pseudomonas environmental reservoirs

✦Neutropenic diet: cooked foods only — no raw produce, raw meat, or unpasteurized dairy

✦G-CSF: bone pain is expected — use acetaminophen, not NSAIDs (NSAIDs mask fever)

✦G-CSF: do NOT give within 24 hours before OR after chemotherapy

✦ANC formula: WBC × (% segs + % bands) ÷ 100
