Study Guide: Skills | 3F | Before Class
Must-Know NCLEX Nursing Skills
NurseAdemy | Class 1 Pre-Class Study Guide
Purpose of This Guide
This guide prepares you for the Skills class without revealing the workbook answers. The topics are intentionally reorganized and grouped by clinical principle rather than by case order.
Focus on what makes a procedure safe, how to recognize when a device or treatment is not working as expected, and which findings require immediate nursing attention.
NurseAdemy Clinical Thinking:
Do not memorize isolated steps. Ask: What is the purpose of the device? What could go wrong? What finding changes the priority?

1. Device Function: Patency, Flow & Closed Systems
Many nursing skills depend on maintaining a clear pathway for fluid, air, nutrition, or drainage.
PatencyA tube or catheter should allow prescribed flow without unexpected resistance, backup, distention, or loss of drainage.
GravityDrainage systems often depend on correct positioning and unobstructed downward flow.
Closed SystemsUnnecessary disconnections increase contamination and infection risk.
Negative PressureClosed-suction drains require the reservoir to maintain the intended suction.
A sudden decrease in output does not always mean improvement. Consider obstruction, loss of suction, kinking, or displacement.
2. Safe Tube Placement & Verification
Whenever a tube is placed into the gastrointestinal tract, the nurse must think about both location and purpose.
Nasogastric TubesKnow the general insertion process, appropriate client positioning, measurement landmarks, and signs that placement may be unsafe.
Before UseDo not assume a tube is safe to use simply because it reached the expected external mark.
DecompressionAssess whether distention, nausea, discomfort, and gastric drainage are improving.
Feeding AccessPlacement verification and aspiration precautions are essential before administering nutrition or medication.
NCLEX Pearl: External length is useful for ongoing comparison, but it does not replace initial placement verification.
3. Airway Safety During Procedures
Procedures involving the airway can create rapid deterioration. The nurse must recognize when the client is no longer tolerating the intervention.
Restlessness Desaturation Bradycardia Increased work of breathing Reduced airflowSuctioningUse suction only when clinically indicated and monitor the client throughout the procedure.
TracheostomyKnow the difference between secretion-related obstruction, tube displacement, and complete decannulation.
Patient FirstIf the client deteriorates during a procedure, restoring oxygenation and airway safety takes priority over completing the technique.
Time limits describe the maximum duration of a procedure—not how long you must continue if the client becomes unstable.
4. Recognizing Local IV Complications
Peripheral IV problems are distinguished by the pattern at the insertion site and by the type of solution or medication infusing.
| Pattern | Clinical Direction |
|---|---|
| Cool, pale, swollen tissue | Think about fluid leaving the vein into surrounding tissue. |
| Warmth, redness, tenderness along the vein | Think about inflammation of the vein. |
| Burning/pain with a tissue-damaging medication | Think about a more serious tissue-injury risk. |
| Resistance or absent flow | Assess before attempting to force the device. |
Do not automatically flush an IV when the site is swollen, painful, or otherwise abnormal.
5. Aspiration Prevention & Feeding Safety
Enteral feeding questions require attention to positioning, feeding tolerance, tube safety, and respiratory assessment.
PositionMaintain appropriate head elevation unless contraindicated.
ToleranceMonitor for nausea, vomiting, abdominal fullness, distention, or other signs of poor tolerance.
Respiratory ChangesNew coughing, wet breath sounds, or oxygenation changes require immediate reassessment.
PatencyKeep the tube functioning safely, but do not prioritize flushing over a new airway concern.
Clinical Thinking: Nutrition is never more important than airway protection.
6. Blood & Infusion Safety
Blood-product questions often test preparation, early monitoring, recognition of a reaction, and sequence of nursing actions.
Before AdministrationVerify client, prescription, product information, baseline assessment, and appropriate tubing/solution.
Early MonitoringRemain especially alert during the early portion of the transfusion.
Reaction CuesNew fever, chills, pain, respiratory symptoms, hypotension, or sudden deterioration require immediate evaluation.
Priority ConceptWhen harm is suspected, stop exposure before moving to reporting and investigation.
A correct phone call can still be the wrong first action if the harmful exposure is continuing.
7. Central Venous Access: Infection, Occlusion & Acute Complications
PICC and central-line questions may present multiple plausible complications. Use the complete pattern rather than one finding.
| Pattern | Think About |
|---|---|
| Progressive fever, local redness, warmth, or drainage | Infection |
| Resistance during flushing or inability to obtain expected flow | Occlusion |
| Arm swelling or discomfort near a PICC | Possible thrombosis |
| Sudden cardiopulmonary deterioration | Acute central-line complication requiring immediate assessment |
Timing Matters:
A complication that develops over hours or days suggests a different process than one that begins suddenly.

8. Urinary Catheter Safety & CAUTI Prevention
Safe Foley care depends on sterile insertion, closed drainage, unobstructed flow, appropriate specimen collection, and early removal when no longer needed.
InsertionUse sterile technique and identify the correct urethral opening.
Low OutputInspect tubing, drainage-bag position, and possible obstruction before assuming renal failure.
SpecimensUse the sampling port rather than disconnecting the closed system.
Routine CarePerform regular perineal hygiene without unnecessary antiseptic overuse.
More manipulation of a catheter is not automatically safer. Preserve the closed system whenever possible.
9. Bleeding, Drainage & Postoperative Trends
Wound-drain questions require trend recognition. Amount and color matter, but they must be interpreted together with the client’s hemodynamic status.
Expected Early DrainageA small amount of serosanguineous output may be expected depending on the procedure.
Concerning TrendIncreasing bright-red drainage deserves evaluation, especially when the amount rises rapidly.
Hemodynamic ContextTachycardia, falling blood pressure, pallor, or worsening weakness increase concern for bleeding.
Drain FunctionA change in output may reflect loss of suction or obstruction rather than a change in bleeding alone.
NCLEX Pearl: Never interpret a drain without assessing the patient.
10. Bladder Irrigation & Output Interpretation
Continuous bladder irrigation requires assessment of both inflow and outflow. The drainage bag contains urine plus irrigation solution.
Calculation Principle:
Actual urine output = total drainage collected − irrigation fluid infused.
Actual urine output = total drainage collected − irrigation fluid infused.
PatencyMonitor for uninterrupted drainage and signs that clots may be interfering with flow.
Bladder FindingsPressure, fullness, distention, or spasms require reassessment of the system.
Drainage ColorObserve trends rather than reacting to a single isolated color description.
SafetyDo not increase inflow without considering whether outflow remains adequate.
11. NCLEX Skill Strategy: Expected, Device Problem, or Client Complication?
| Step | Ask Yourself |
|---|---|
| Recognize Cues | What changed from baseline? |
| Identify the System | Is this a tube, airway, infusion, catheter, drain, or client problem? |
| Differentiate | Is the finding expected, a mechanical problem, or a physiologic complication? |
| Prioritize | Which issue threatens airway, breathing, circulation, tissue integrity, or infection control first? |
| Act | Which action stops further harm or restores safe function? |
| Evaluate | What should improve if the intervention worked? |
NurseAdemy Rule: A distractor may describe a real nursing action. The challenge is deciding whether it is the correct action for this client at this moment.
Before Class, Be Ready to Explain:
- How to recognize whether a tube, catheter, line, or drain is functioning safely.
- Which findings suggest obstruction, aspiration, bleeding, infection, or tissue injury.
- Why timing changes the priority nursing action.
- When a procedure should be stopped because the client is deteriorating.
- Why a reassuring device finding does not always mean the client is stable.
- How to distinguish an expected postoperative finding from a complication.
Final Question:
Is this finding expected, is the device failing, or is the client developing a complication?
