A nurse is caring for a client with acute lymphoblastic leukemia (ALL) who has been receiving chemotherapy for 2 weeks. Which assessment finding would be the priority concern requiring immediate nursing intervention?

해설
Fever with chills and diaphoresis in a neutropenic client indicates potential infection, which is a life-threatening emergency requiring immediate intervention. Other findings (thrombocytopenia, anemia, leukopenia) are concerning but less urgent.

Core Nursing Explanation This question tests the critical nursing skill of priority setting for a patient with Acute Lymphoblastic Leukemia (ALL) undergoing chemotherapy. The core principle is recognizing that Key Point! fever in a patient who is immunocompromised (neutropenic) is a medical and nursing emergency, often referred to as Febrile Neutropenia. Key Concept Analysis: Chemotherapy targets rapidly dividing cells, which includes not only cancer cells but also the bone marrow's hematopoietic stem cells. This leads to Myelosuppression, causing a drop in all blood cell lines: Neutropenia (low neutrophils, a type of WBC), Thrombocytopenia (low platelets), and Anemia (low red blood cells). While all are serious, the most immediate life-threatening complication is infection due to neutropenia. A patient with a severely low neutrophil count has a drastically impaired ability to fight infection. A fever may be the only sign of a serious, potentially fatal infection, as the typical inflammatory response (redness, swelling, pus) may be absent. Answer Rationale: Option ① is correct because it presents the classic signs of a systemic infection: Temperature of 101.2°F (38.4°C) (fever), chills, and diaphoresis. In this context, it signals Febrile Neutropenia, which requires immediate intervention (blood cultures, broad-spectrum IV antibiotics, close monitoring) to prevent progression to Sepsis and septic shock. Distractor Analysis: Watch out for confusion! Option ② (Platelet count of 45,000/mm³ with petechiae): Thrombocytopenia is a serious risk for bleeding. However, the priority is Airway, Breathing, Circulation (ABC). An active bleed threatening circulation is an emergency, but petechiae alone indicates a risk, not an active, life-threatening hemorrhage. Infection (fever) is a more immediate threat to all body systems. Option ③ (Hemoglobin of 8.2 g/dL with fatigue): Anemia is common and causes significant symptoms like fatigue. However, the body can often compensate for chronic anemia. It requires intervention (e.g., transfusion per protocol) but is not typically an immediate life threat like an uncontrolled infection. Option ④ (WBC count of 2,500/mm³ alone): Leukopenia/Neutropenia is the condition that creates the risk. Without the symptom of fever, it is a laboratory finding that requires protective isolation (neutropenic precautions) and monitoring, but not the same level of urgent intervention as an active, suspected infection. Related Concepts: The nursing priority follows the ABCs and Maslow's Hierarchy of Needs. A systemic infection directly threatens physiological needs (oxygenation, circulation) and is therefore the highest priority. Remember the mnemonic for chemotherapy side effects: "B.M.W." – Bone marrow suppression, Mucositits, Well-being (N/V). Bone marrow suppression leads to the triad of problems in this question.

Side-by-Side Comparison!
ScenarioImmediate Action (Priority)Rationale
Febrile Neutropenia (Fever + Low WBC)STAT blood cultures x2 & Broad-spectrum IV antibiotics.Infection can become fatal within hours. Do not wait for culture results.
Thrombocytopenia + Active Bleeding (e.g., GI bleed)Apply direct pressure, notify provider, prepare for platelet transfusion.Active bleeding threatens circulation (C in ABCs).
Thrombocytopenia + Petechiae Only (No active bleed)Implement bleeding precautions, monitor closely.This is a risk, not an active life-threatening problem.

Anatomy, Physiology & Pharmacology Points
  • Pathophysiology: Chemotherapy causes myelosuppression by damaging the bone marrow. Neutrophils have a short lifespan (~7 hours), so their count drops quickly, leaving the body defenseless.
  • Lab Value: The critical value is the Absolute Neutrophil Count (ANC). ANC < 500 cells/mm³ = severe risk. Fever (often defined as a single temp ≥ 100.4°F / 38.0°C or ≥ 100°F / 37.8°C over 1 hour) in this setting is an emergency.
  • Pharmacology: First-line intervention is empiric broad-spectrum antibiotics (e.g., piperacillin-tazobactam, cefepime) to cover potential gram-negative and gram-positive organisms until cultures identify the specific pathogen.

Memory Tips
  • Mnemonic: "Fever First!" For a chemo patient, think Fever = Fire drill = First priority.
  • Rule of Thumb: Any fever in a patient receiving chemotherapy should be treated as a potential septic emergency until proven otherwise. "When in doubt, check it out—immediately."

High-Frequency NCLEX Topics NCLEX heavily tests priority setting and oncology emergencies. Febrile neutropenia is a classic. You must be able to distinguish between a serious concern (low platelets) and an immediate life-threatening emergency (fever with neutropenia). Expect questions that list multiple abnormal findings and ask "Which requires immediate intervention?" or "Which finding should the nurse report first?"
Watch Out for Question Variations!
  • Symptom Focus: "A client on chemotherapy has a temperature of 101.5°F (38.6°C). Which action should the nurse take first?" (Answer: Obtain blood cultures.)
  • Teaching Focus: "Which instruction is most important for the nurse to include when teaching a client with neutropenia?" (Answer: "Report any fever of 100.4°F (38.0°C) or higher immediately.")
  • Intervention Focus: "The nurse is reviewing orders for a client with febrile neutropenia. Which order should be implemented first?" (Answer: Administer IV cefepime.)

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the day-shift nurse for Mr. Johnson, a 58-year-old with ALL, day 10 post-chemotherapy cycle. During your morning assessment, he says he feels "achy and chilly." You take his vital signs: Temp 101.8°F (38.8°C), HR 112, BP 118/70. He has no obvious site of infection. Nursing Intervention Strategy: 1. Immediate Assessment & Action (First 5-10 minutes): * Isolate & Protect: Don appropriate PPE. Place the patient on Neutropenic Precautions (private room, no fresh flowers/plants, strict hand hygiene, limit visitors). * Notify: Immediately call the provider (oncologist or hospitalist) to report the fever. This is a STAT notification. * Culture: Obtain two sets of Blood cultures from two different peripheral sites (or from a central line lumen and a peripheral site) before starting antibiotics if possible, but do not delay antibiotics to draw cultures. 2. Collaborative Care (Provider Orders Expected): * Medications: Administer prescribed broad-spectrum IV antibiotics promptly. Monitor for allergic reactions. * Monitoring: Monitor vital signs frequently (every 1-2 hours initially). Perform a thorough head-to-toe assessment looking for subtle signs of infection (e.g., subtle redness at IV site, mouth sores, perianal tenderness, cloudy urine). * Supportive Care: Administer antipyretics as ordered (typically acetaminophen; avoid NSAIDs like ibuprofen due to bleeding risk with thrombocytopenia). Promote comfort for chills with warm blankets. Patient Safety and Precautions: * Key Point! Do NOT administer rectal suppositories or take rectal temperatures due to the high risk of mucosal injury and bacteremia in a neutropenic patient. * Avoid intramuscular (IM) injections for the same reason (injury and infection risk). * Meticulous oral and perineal care are essential to prevent breaks in mucosal barriers where infection can start.
Nursing Procedure & Medication Flow Procedure: Responding to Febrile Neutropenia 1. Assess patient: Vital signs, symptoms, review most recent CBC with differential. 2. Notify provider STAT with SBAR report: Situation (febrile neutropenic patient), Background (ALL, post-chemo day 10), Assessment (temp 101.8°F, tachycardic, chills), Recommendation (request orders for blood cultures and IV antibiotics). 3. Obtain blood cultures. 4. Administer first dose of IV antibiotics within 1 hour of fever recognition (this is a common quality metric). 5. Continue frequent monitoring and supportive care. 6. Document everything thoroughly: time of fever onset, interventions, provider notifications, patient response.
A Word from Your Senior Nurse "In oncology nursing, your assessment skills are your patient's first line of defense. That low-grade fever might seem minor, but in this population, it's a five-alarm fire. Never become complacent with a 'low-grade' temp in a chemo patient. Your quick thinking and strict adherence to neutropenic fever protocols can literally save a life. On the NCLEX, they are testing this clinical judgment—can you recognize what is urgent versus what is important? Carry that same sharp judgment to the bedside."

핵심 개념

  • Febrile Neutropenia — A medical emergency defined by a single oral temperature of ≥100.4°F (38.0°C) or a temperature ≥100°F (37.8°C) sustained over one hour in a patient with an absolute neutrophil count (ANC)
  • Myelosuppression — Bone marrow suppression, a common side effect of chemotherapy and radiation therapy. It results in decreased production of blood cells, leading to neutropenia, thrombocytopenia, and anemia.
  • Absolute Neutrophil Count — A calculated value (WBC x (%Segs + %Bands)) that represents the actual number of neutrophil cells available to fight infection. An ANC
  • Neutropenic Precautions — Protective isolation measures for patients with low neutrophil counts. Includes a private room, strict hand hygiene, no fresh flowers/plants, avoiding sick visitors, and meticulous cleaning. Also called "reverse isolation."
  • Empiric Therapy — Treatment initiated based on clinical experience and probability, before a specific pathogen is identified by diagnostic tests. In febrile neutropenia, this refers to starting broad-spectrum IV antibiotics immediately to cover the most likely infectious organisms.
