NCLEX PN Physiological Integrity Reduction of Risk Potential FAQs
1. What are the key nursing responsibilities when monitoring diagnostic test results (e.g., lab values, imaging)?
Licensed Practical Nurses (LPNs) play an essential role in interpreting diagnostic test results and responding appropriately. They must be familiar with normal reference ranges for common lab tests such as CBC, BMP, coagulation studies (PT/INR, aPTT), and urinalysis. Recognizing critical values, such as dangerously high potassium (>6.0 mEq/L) or very low hemoglobin (<7 g/dL), requires immediate action.
Monitoring trends is equally important—even values within the normal range may indicate improvement or deterioration based on their movement over time. Promptly reporting significant or abnormal findings to the RN or healthcare provider and documenting communication thoroughly is a crucial nursing responsibility.
Patient preparation for tests, such as educating about NPO status before an abdominal ultrasound or contrast imaging, helps ensure accurate results.
After receiving results, LPNs often assist with follow-up care by implementing new treatment orders or increasing monitoring as directed.
In preparation for your NCLEX PN exam, focus on lab values and test result interpretation. Practice with NCLEX PN practice questions that cover these critical areas to strengthen your understanding.

2. How can nurses prevent complications related to diagnostic or therapeutic procedures (e.g., biopsies, endoscopy)?
LPNs help maintain patient safety by ensuring all protocols are followed before, during, and after procedures:
- Pre-procedure: Confirm informed consent, verify correct patient and procedure, assess allergies (especially to iodine or contrast agents), and ensure the patient completes preparation requirements like fasting or bowel prep.
- Intra-procedure: Although LPNs may not perform complex interventions, they monitor vital signs, observe for distress such as hypoxia or bleeding, and provide reassurance to anxious patients.
- Post-procedure: Nurses monitor for complications such as hemorrhage, infection, or perforation. They assess biopsy sites for bleeding or discharge, check vital signs regularly, and educate patients about symptoms that require immediate reporting (e.g., black tarry stools indicating gastrointestinal bleeding).
Accurate documentation of the procedure details and patient response is vital for continuity of care.
3. What steps do nurses take to identify and prevent potential complications from medical devices (e.g., catheters, drains)?
LPNs must monitor medical devices vigilantly to prevent complications:
- Catheters (e.g., Foley): Use correct insertion techniques to prevent trauma and infection, maintain a closed drainage system, monitor urine for cloudiness or foul odor, and secure tubing to avoid accidental dislodgement.
- Drains (e.g., Jackson-Pratt, Hemovac): Regularly assess drainage volume, color, and consistency; maintain suction; empty and document output; watch for signs of blockage or infection at the insertion site.
- IV lines: Inspect the site for infiltration, phlebitis, or infection signs; flush lines to maintain patency; ensure dressings are changed per protocol; label lines clearly.
Refer to the Centers for Disease Control and Prevention (CDC) guidelines on catheter-associated infections for evidence-based practices.
4. How should a nurse respond to early signs of complications like hypoxia, bleeding, or altered mental status?
Early recognition and intervention are vital:
- Hypoxia: Signs include restlessness, confusion, tachypnea, and cyanosis. Nurses should elevate the head of the bed, administer oxygen, monitor pulse oximetry, and notify the RN or healthcare provider immediately.
- Bleeding: Watch for tachycardia, hypotension, pallor, decreased hemoglobin, or visible bleeding. Apply pressure to external bleeding, monitor vital signs closely, initiate IV fluids if ordered, and keep the patient calm.
- Altered Mental Status: Look for confusion, lethargy, agitation, or sudden behavioral changes. Ensure patient safety with fall precautions, check oxygenation and blood glucose levels, and report findings promptly.
Prompt escalation and detailed documentation help prevent progression to critical situations.
These concepts are frequently tested in NCLEX PN tests related to patient safety.
Additional guidance on recognizing complications can be found on the Mayo Clinic Patient Care Guidelines.
5. What is the nurse’s role in managing patients with sensory or mobility impairments to reduce risk?
Patients with sensory deficits or limited mobility are at increased risk for injury and complications. Nurses must:
- Modify the environment: Ensure pathways are clear, clutter-free, and well-lit; keep call lights and assistive devices within easy reach.
- Use effective communication: For hearing-impaired patients, use visual aids or written instructions; speak clearly and face the patient directly.
- Assist with mobility: Use gait belts and safe transfer techniques; implement fall precautions such as non-skid footwear, bed alarms, and low bed positions.
- Monitor skin integrity: Reposition immobile patients every two hours, use pressure-relieving cushions or mattresses.
- Educate patients and families: Teach safe ambulation and device use; involve family members in supporting safe care routines.
These interventions reduce falls, pressure ulcers, and social isolation — essential knowledge for lpn practice questions and NCLEX PN test preparation.
