Study Guide: Fundamentals | 3S | Previo a la clase
📚 Antes de Comenzar
NurseAdemy | NCLEX FundamentalsEsta guía debe revisarse antes de la clase. Su propósito es ayudarte a llegar preparado para analizar escenarios clínicos de Fundamentals relacionados con dolor, movilidad segura, integridad de la piel, nutrición, prevención de complicaciones y juicio clínico estilo NGN.
Durante la clase no solo identificaremos datos anormales. También aprenderemos a decidir cuáles hallazgos requieren seguimiento, cuáles intervenciones deben implementarse primero y cómo cambia la prioridad del cliente cuando aparecen nuevos datos.
En Fundamentals, el estudiante avanzado no memoriza listas. Aprende a reconocer riesgos, conectar datos clínicos y anticipar complicaciones antes de que el cliente se deteriore.
Learning Objectives
By the end of this pre-class preparation, the student should be able to:
- Identify when an observational pain scale is appropriate.
- Select safe mobility and transfer strategies based on client ability.
- Differentiate expected aging findings from findings that suggest skin breakdown.
- Recognize risk factors for pressure injury progression.
- Connect nutrition and laboratory values with wound healing.
- Recognize how immobility contributes to multiple complications.
- Identify early signs of postoperative pulmonary complications.
- Evaluate whether a client has improved, remained unchanged, or worsened after nursing interventions.
You do not need to know the workbook answers before class. You need to arrive ready to explain why a finding matters, what risk it creates, and what the nurse should monitor next.
1. Pain Assessment: Self-Report vs. Observational Scales
Pain assessment begins with the client’s self-report whenever the client can communicate reliably. However, some clients cannot describe pain using a numeric, visual, or verbal pain scale.
PAINAD is used when a client cannot reliably self-report pain, especially in advanced dementia or severe cognitive impairment.
Numeric Rating Scale, visual pain scale, communication barriers, dementia, aphasia, hearing loss, and ability to follow commands.
Ask yourself: Can this client understand the question and communicate a consistent pain response?
2. Safe Mobility & Patient Handling
Safe mobility questions require the nurse to protect both the client and healthcare staff. The safest transfer method depends on the client’s weight-bearing status, strength, ability to follow commands, cooperation, and body size.
A client who cannot assist with movement may require mechanical transfer equipment rather than manual lifting.
Gait belt, walker, partial weight-bearing, hemiplegia, mechanical lift, bariatric safety, and fall prevention.
Ask yourself: Can the client bear weight and follow commands safely, or does the nurse need additional equipment?
Why is “the strongest staff member can help” not a safe patient handling strategy?
3. Pressure Injury Risk: More Than Redness
Pressure injuries develop when tissue tolerance decreases and pressure, moisture, friction, or shear remain uncorrected. In NCLEX-style questions, pressure injury risk usually comes from several findings together.
Continuous pressure over bony prominences reduces tissue perfusion and can lead to skin breakdown.
Urinary or fecal incontinence can macerate the skin and increase injury risk.
Shear occurs when the skin stays in place while deeper tissues move, such as when a client slides down in bed.
4. Expected Aging vs. Skin Breakdown
Older adults often have thinner, drier, more fragile skin. However, some findings suggest tissue injury and require nursing follow-up.
Thin skin, dry skin, easy bruising, and age spots may be common in older adults.
Non-blanchable erythema, warmth, tenderness, moisture-related skin changes, and pressure over bony prominences.
Ask yourself: Is this a normal age-related finding, or does it suggest tissue damage or risk for progression?
Why is non-blanchable redness more concerning than dry skin alone?
5. Nutrition, Labs & Wound Healing
Nutrition supports tissue repair, immune function, collagen formation, and recovery after surgery. Poor intake and abnormal nutrition-related labs can increase the risk for delayed healing.
Reflects longer-term nutritional status and can help identify poor healing risk.
May reflect more recent nutritional changes.
Helps evaluate oxygen delivery to tissues but must be interpreted with the full clinical picture.
Help the nurse think about hydration status and renal function trends.
6. Interventions: Correct vs. Priority
Many nursing interventions may be appropriate, but the NCLEX often asks which actions should be implemented first. This requires priority thinking, not memorization.
Reduce pressure, reduce moisture, minimize friction and shear, and protect bony prominences.
Pain control may be needed before the client can participate in mobility or repositioning.
Nutrition, therapy consults, and discharge planning matter, but may not always be the first action.
How can an intervention be correct but not the priority?
7. Postoperative Pulmonary Complications
After surgery, pain and immobility can cause shallow breathing. If the client avoids coughing, deep breathing, incentive spirometry, or ambulation, pulmonary complications may develop.
Shallow respirations and reduced chest expansion can lead to incomplete alveolar expansion.
Incentive spirometry, coughing, deep breathing, pain control, early ambulation, oxygen saturation, and respiratory rate.
Ask yourself: Is the client avoiding breathing deeply because of pain, and what complication could occur next?
8. Atelectasis vs. Pneumonia vs. Pulmonary Embolism
Postoperative clients may develop several complications that can look similar at first. The nurse must analyze the pattern of findings instead of choosing based on one cue.
Shallow breathing, decreased chest expansion, diminished breath sounds, low-grade fever, and decreased oxygen saturation.
Fever, productive cough, worsening breath sounds, increased secretions, and signs of infection.
Sudden dyspnea, chest pain, tachycardia, hypoxemia, and risk factors such as surgery and immobility.
Why does the nurse need to compare the pattern of findings instead of focusing on one abnormal vital sign?
9. Changing Priorities During a Shift
A client may begin the shift with one priority and later develop a new, more urgent problem. Clinical judgment requires the nurse to reassess continuously and avoid anchoring on the first concern.
A client with immobility, poor intake, and pressure over bony prominences may require skin protection.
If respiratory status changes, breathing and oxygenation may become the immediate priority.
Ask yourself: Has a new finding appeared that changes what the nurse should address first?
10. Evaluating Outcomes: Improved, Unchanged, Worsened
After interventions, the nurse must compare the current assessment with previous data. The question is not always whether the client is normal. The question may be whether the client improved compared with the previous assessment.
The finding has moved in a better direction compared with the previous assessment.
The finding remains present without meaningful improvement or worsening.
The finding has intensified, expanded, decreased in function, or a new complication has developed.
Bonus Review: NCLEX Fundamentals Thinking Rules
Use these rules to guide your thinking before class. They are not answers; they are decision-making tools.
Identify which data matter before selecting an action.
Several interventions may be appropriate, but only some are priority.
Compare the client’s current status with previous assessments.
New data can change the priority problem.
Safe patient handling protects both the client and the nurse.
Determine whether the client improved, remained unchanged, or worsened.
Before class, focus on recognizing risk, connecting cues, anticipating complications, and explaining why one nursing action is safer or more urgent than another.
