A 12-year-old child with cystic fibrosis is admitted to the pediatric unit with increased respiratory distress and thick, tenacious secretions. The child's oxygen saturation is 88% on room air, and chest physiotherapy has been ordered. Which nursing intervention should be the priority?

해설
Administering bronchodilators before chest physiotherapy is the priority to dilate airways and mobilize thick secretions in cystic fibrosis, optimizing therapy effectiveness. Other options are supportive but do not address immediate airway clearance needs.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a child with Cystic Fibrosis (CF) experiencing an acute exacerbation with respiratory distress. The core pathophysiology involves defective chloride channels leading to thick, dehydrated mucus that obstructs airways, causing atelectasis, infection, and impaired gas exchange. The immediate threat is hypoxemia (SpO2 88%) and difficulty clearing tenacious secretions.

Answer Rationale: Key Point! The priority is to optimize the effectiveness of the ordered chest physiotherapy (CPT). Administering a bronchodilator (e.g., albuterol) before CPT is a standard, evidence-based sequence. The bronchodilator works by relaxing the smooth muscles of the airways, dilating them, which allows the subsequent percussion and postural drainage techniques to more effectively loosen and mobilize the thick secretions from the smaller airways. This directly addresses the immediate problem of airway clearance and can improve oxygenation.

Distractor Analysis: Watch out for confusion!
Option ②: Increasing fluid intake is a crucial long-term management strategy in CF to help thin secretions systemically. However, in an acute setting with current distress, its effect is not immediate. It is important but not the priority intervention to prepare for the imminent CPT session.
Option ③: Positioning in high Fowler's can ease work of breathing and is a supportive measure. However, it does not actively facilitate the clearance of the thick secretions that are the root cause of the current distress. It is a comfort and positioning measure, not the priority preparatory intervention for therapy.
Option ④: Scheduling frequent CPT sessions is part of the care plan. However, the question asks for the priority intervention now, implying what to do to make the next session effective. Simply scheduling it does not address how to perform it most effectively for this distressed child.

Related Concepts: The nursing process requires prioritizing actions that have the most immediate impact on the patient's primary problem (airway clearance). The sequence of care—medication to open airways, then physical mobilization of secretions—is a fundamental principle in managing obstructive pulmonary diseases like CF, COPD (Chronic Obstructive Pulmonary Disease), and bronchiectasis. Concept Summary
ConceptKey Points
Cystic Fibrosis PathophysiologyAutosomal recessive disorder. Defect in CFTR protein leads to thick, sticky mucus in lungs and pancreas. Results in chronic infection, inflammation, and progressive lung damage.
Chest Physiotherapy (CPT)Includes postural drainage, percussion, vibration. Goal is to mobilize secretions from peripheral airways to central airways for expectoration.
Bronchodilators in CFOften used before CPT to open airways. Common drug: Short-acting beta-agonists (SABAs) like albuterol.
Airway Clearance TechniquesHierarchy: Open airway first (meds), then mobilize secretions (CPT), then expect/have patient cough. Hydration supports overall thinning.
Side-by-Side Comparison!
InterventionPurpose & TimingWhy It's Not the *Immediate* Priority Here
Administer BronchodilatorTo dilate airways before CPT, making secretion removal more effective. Directly prepares for the ordered therapy.This IS the priority. It's the preparatory step that maximizes the benefit of the critical intervention (CPT).
Increase Fluid IntakeLong-term systemic hydration to thin secretions. Vital for daily management.Effect is delayed (hours). Does not immediately improve the efficacy of the next CPT session.
High Fowler's PositionSupportive measure to ease breathing by reducing pressure of abdominal contents on diaphragm.Passive. Does not actively clear the obstructing secretions causing the hypoxemia.
Anatomy, Physiology & Pharmacology Points Physiology: Normal ciliary function requires thin mucus. In CF, thick mucus impairs ciliary clearance, leading to mucus plugging, bacterial colonization (often Pseudomonas aeruginosa), and chronic inflammation.
Pharmacology: Albuterol is a beta-2 adrenergic agonist. It binds to receptors on bronchial smooth muscle, activating a cascade that leads to muscle relaxation (bronchodilation). This effect is usually seen within minutes, making it ideal for pre-CPT use. Memory Tips ABCs with a CF Twist: For CF exacerbation, think Airway Open, Breathing Clear, Circulation/Comfort. Bronchodilator opens the Airway, CPT clears Breathing.
Sequence Mnemonic: "Before you Pound, Open the passage!" (Bronchodilator -> Percussion/Postural drainage). High-Frequency NCLEX Topics CF is a classic pediatric chronic illness topic. NCLEX loves to test: 1) Priority actions during an exacerbation (airway always first), 2) The correct sequence of therapies (meds before CPT), 3) Nutritional considerations (pancreatic enzyme replacement with meals), and 4) Infection control (CF patients should not room together due to different bacterial colonization). Watch Out for Question Variations! * Instead of "priority intervention," it could ask: "Which action should the nurse take first?" The answer logic is identical. * The scenario could shift to evaluating effectiveness: "Which finding indicates the chest physiotherapy was effective?" (Answer: Improved breath sounds, productive cough, increased SpO2). * It could test patient education: "The nurse is teaching the parents about home CPT. Which statement by a parent indicates understanding?" (Correct: "We will give the albuterol treatment about 15 minutes before starting the chest percussion.").

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a pediatric pulmonary unit. Your patient, a 12-year-old with known CF, is anxious, using accessory muscles to breathe, and has a frequent weak cough producing small amounts of very thick, greenish sputum. SpO2 is 88% on room air. The provider has ordered: Albuterol 2.5 mg via nebulizer, CPT every 4 hours and as needed, and encourage PO fluids.

Nursing Intervention Strategy: 1. Assessment: Complete a focused respiratory assessment (rate, effort, breath sounds, sputum characteristics). Check vital signs and SpO2 continuously. Assess the child's anxiety level and ability to cooperate. 2. Planning & Implementation: * Priority Action: Explain the procedure to the child to reduce anxiety. Administer the nebulized albuterol first. Allow 10-15 minutes for it to take effect. * During CPT: Position the child according to the postural drainage plan (often focusing on lower lobes first). Use proper percussion technique with a cupped hand or mechanical device over the rib cage (not over spine or kidneys). Encourage deep breathing and coughing during and after the session. * After CPT: Assist with effective coughing or suction if needed. Reassess breath sounds, respiratory effort, and SpO2. Provide oral care and a rest period. 3. Patient/Family Education: Teach the importance of the medication-therapy sequence. Demonstrate proper percussion and positioning. Discuss signs of respiratory distress to report.

Patient Safety and Precautions: * Key Point! Never perform CPT immediately after a meal (risk of vomiting/aspiration). Wait at least 1-2 hours. * Contraindications/precautions for CPT: Active hemoptysis, fractured ribs, osteoporosis, pulmonary embolism. * Monitor for side effects of bronchodilators: tachycardia, tremors, nervousness. Nursing Procedure & Medication Flow Pre-CPT Procedure: 1. Verify order for bronchodilator and CPT. 2. Gather equipment: nebulizer kit, medication, CPT device or your hands (use blanket for comfort), tissues, emesis basin, pulse oximeter. 3. Assess patient baseline (vitals, lung sounds, SpO2). 4. Administer bronchodilator via nebulizer over 10-15 mins. 5. Wait 5-10 minutes post-neb for maximal bronchodilation. 6. Position patient and begin CPT. Session typically lasts 20-30 minutes. 7. Evaluate outcomes and document. A Word from Your Senior Nurse "In the hustle of a busy shift, it's easy to just jump into doing the 'big' task like chest physiotherapy. But remember, nursing is about smart, effective care. Taking those 15 minutes to give the bronchodilator first is like oiling a rusty hinge before trying to open the door—it makes everything that follows so much more successful. You're not just following an order; you're applying pathophysiology to maximize your patient's benefit. On the NCLEX and at the bedside, thinking 'what needs to happen first to make the next step work?' will guide you to the right answer and the best care."
