A nurse is caring for a patient who underwent a bone marrow biopsy 2 hours ago. Which nursing action is the priority to ensure patient safety?

Following a bone marrow biopsy, monitoring the site for bleeding or hematoma is the priority due to the invasive procedure and high bleeding risk. Other options are important but do not address the immediate safety concern.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing action following an invasive diagnostic procedure, specifically a bone marrow biopsy. The core principle is post-procedure monitoring for complications, with the primary safety concern being hemorrhage. The biopsy needle penetrates the bone cortex (often the posterior iliac crest), which is a highly vascular area. The priority is to prevent and detect early signs of bleeding, which can lead to a significant hematoma or, in severe cases, hypovolemia.

Answer Rationale: Key Point! Option ③ is correct because it directly addresses the most immediate and potentially life-threatening complication. Monitoring the biopsy site for active bleeding, swelling, or hematoma formation is a direct assessment for the primary complication. This action aligns with the nursing process by focusing on assessment first to identify any problems before implementing other interventions. It ensures patient safety by allowing for early intervention (e.g., applying direct pressure) if bleeding occurs.

Distractor Analysis:
Watch out for confusion! Option ① (Encourage early ambulation) is contraindicated immediately after a bone marrow biopsy. The patient is typically kept on bed rest for a period (often 30-60 minutes) to apply pressure to the site and prevent dislodgement of the forming clot. Early ambulation could increase the risk of bleeding.
Option ② (Administer pain medication) is a comfort measure and is important for patient-centered care, but it is not the priority for safety. Safety (preventing hemorrhage) takes precedence over comfort.
Option ④ (Assess vital signs every 4 hours) is a standard monitoring practice but is not frequent or specific enough for the immediate post-procedure period (2 hours ago). More frequent vital sign assessment (e.g., every 15-30 minutes initially) might be indicated if there is concern for bleeding, but the direct site inspection in option ③ is a more specific and immediate assessment for the primary risk.

Related Concepts: This question integrates knowledge of hematologic procedures, post-procedure care priorities (ABCs), and risk for injury related to invasive procedures. The principle can be applied to other procedures involving deep tissue or vascular access (e.g., liver biopsy, arterial puncture). Concept Summary

Concept	Key Points
Bone Marrow Biopsy	Invasive procedure to obtain marrow sample, usually from posterior iliac crest. High risk for bleeding.
Priority Complication	Hemorrhage and hematoma formation at the puncture site.
Priority Nursing Action	Direct inspection and palpation of the biopsy site for bleeding, swelling, tenderness.
Contraindicated Action	Early ambulation; patient should maintain pressure on site via positioning (supine).
Nursing Process Focus	Assessment (for complications) before intervention (for comfort or mobility).

Side-by-Side Comparison!

Post-Procedure Priority: Biopsy vs. Surgery	Bone Marrow / Liver Biopsy	Major Abdominal Surgery
Primary Immediate Concern	Internal/External Bleeding at puncture site	Airway & Breathing (from anesthesia), then bleeding
Key Nursing Assessment	Inspect biopsy site, vital signs for hypovolemia	Airway patency, respiratory rate/effort, surgical incision/drain output
Positioning	Supine to apply pressure to site (posterior hip)	Varies (e.g., semi-Fowler's for abdominal procedures)
Ambulation	Restricted initially (30-60 min bed rest)	Encouraged early (post-op day) to prevent atelectasis, DVT

Anatomy, Physiology & Pharmacology Points Anatomy: The preferred site is the posterior iliac crest because it is rich in marrow, easily accessible, and has no major nerves or blood vessels directly in the path of a properly placed needle.
Physiology: Bone (cancellous bone) is highly vascular. Disruption of the bone cortex and marrow sinusoids can lead to slow, persistent oozing that may not be immediately apparent on the skin surface but can form a large, painful subcutaneous hematoma.
Pharmacology: Patients on anticoagulants (warfarin, heparin) or antiplatelets (aspirin, clopidogrel) are at significantly increased risk. These medications may need to be held prior to the procedure per physician order. Memory Tips Mnemonic: "Bone Bleeds" (B.B.)
Bone Marrow Biopsy -> Bleeding is the #1 concern.
Think "PRESS" for Post-Biopsy Care:
Pressure on site (positioning)
Rest (bed rest initially)
Examine site (for hematoma)
Signs of bleeding (vital signs)
Severe pain? (can indicate hematoma) High-Frequency NCLEX Topics This is a classic "priority-setting" and "safety" question. The NCLEX-RN loves to test your ability to distinguish between an important action and the most important or priority action. Always ask yourself: "What is the greatest threat to the patient's safety right now?" For invasive procedures, the answer is often bleeding, infection, or impaired circulation to the affected area. Watch Out for Question Variations! * Shift in Focus: Instead of "priority action," the question could ask for the "nursing diagnosis" (Risk for Bleeding) or the "purpose of applying pressure" (to promote hemostasis). * Patient Teaching: "Which instruction is most important to give a patient discharged after a bone marrow biopsy?" (Answer: Report signs of bleeding/infection at the site, or avoid strenuous activity for 24-48 hours). * Lab Value Connection: The question could include that the patient has thrombocytopenia (low platelets < 150,000/mm³), making the risk of bleeding even higher and further justifying the priority of site monitoring.

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a medical-surgical unit. Mr. Johnson, 68, with suspected myelodysplastic syndrome, has just returned from having a bone marrow biopsy performed in his room 2 hours ago. He is resting in bed but mentions the site is "achy."

Nursing Intervention Strategy: 1. Assessment: First, perform a focused assessment. Don gloves. Ask Mr. Johnson to roll onto his side (if he was supine). Inspect the posterior iliac crest site. Look for any active bleeding, fresh blood on the dressing, or visible swelling/ecchymosis. Gently palpate around the dressing for warmth, tenderness, or a firm, raised area indicating a hematoma. Assess his vital signs, noting tachycardia or hypotension, which could signal occult blood loss. 2. Planning & Implementation: If the site is clean, dry, and intact, reinforce the dressing as needed. Ensure he remains on bed rest or limits activity per protocol (often for 30-60 minutes post-procedure). Administer prescribed analgesics (option ②) after your safety assessment. Educate him to report any increase in pain, feeling of pressure at the site, or dizziness. 3. Evaluation: Re-evaluate the site in 15-30 minutes and again in one hour. Document the appearance of the site, the patient's tolerance of the procedure, and any interventions provided.

Patient Safety and Precautions: * Contraindication: Do not massage the biopsy site. This can disrupt clot formation. * Key Monitoring: A rapidly expanding hematoma can cause compartment syndrome in the gluteal region, though rare. Severe, unrelenting pain is a red flag. * Infection Control: Maintain sterile dressing for 24-48 hours. Teach the patient to keep the site clean and dry. Nursing Procedure & Medication Flow Post-Bone Marrow Biopsy Monitoring Procedure: 1. Verify physician's orders regarding positioning and activity. 2. Perform hand hygiene and don gloves. 3. Assess biopsy site: Inspect dressing, look under patient if needed. 4. Palpate gently around site for swelling/tenderness. 5. Assess vital signs (BP, HR, RR) – compare to baseline. 6. Ask patient about pain level (use pain scale). 7. If site is stable, assist with comfort measures (analgesia, positioning). 8. Document findings and interventions. 9. Re-assess per unit protocol (e.g., every 15 min x 1 hr, then every hour x 4 hrs).
A Word from Your Senior Nurse "In the real world, patients often downplay discomfort after procedures. That 'achy' feeling Mr. Johnson described could be normal post-procedure soreness, or it could be the first hint of a forming hematoma. Your skilled assessment makes the difference. Never skip the direct visual check because the vital signs are 'stable.' A hidden hematoma can cause a significant drop in hemoglobin hours later. By making site inspection your unwavering priority, you're practicing true preventative nursing and catching complications before they become emergencies. On the NCLEX and at the bedside, remember: See it, don't just assume it's okay."
