A 3-month-old infant with congenital heart failure is admitted to the pediatric unit with worsening symptoms. The nurse notes increased work of breathing, poor feeding, and weight gain of 1.5 pounds over the past week. Which nursing action should the nurse prioritize first?
1Administer prescribed furosemide (Lasix) as ordered✓ 정답
2Obtain a chest X-ray to assess cardiac enlargement
3Weigh the infant to establish baseline weight
4Place the infant in high Fowler's position
해설
In heart failure exacerbation, fluid overload (2 lb weight gain) is life-threatening. Administering furosemide reduces preload and improves cardiac output as the priority. Other options (chest X-ray, weighing, positioning) are important but do not address the immediate fluid overload.
Core Nursing ExplanationKey Concept Analysis: This question assesses the nurse's ability to prioritize interventions for an infant experiencing an exacerbation of Congestive Heart Failure (CHF). The core pathophysiology involves the heart's inability to pump effectively, leading to fluid overload and pulmonary congestion. The infant's symptoms—increased work of breathing, poor feeding, and significant weight gain (1.5 lbs in a week)—are classic signs of worsening fluid status. In pediatric CHF, weight is a Key Point! sensitive indicator of fluid balance; a rapid gain signals volume overload.
Answer Rationale: The priority nursing action is to Administer prescribed furosemide (Lasix) as ordered. Furosemide is a loop diuretic that promotes the excretion of sodium and water, thereby reducing preload (the volume of blood returning to the heart). By decreasing the circulating fluid volume, it directly addresses the life-threatening issues of pulmonary edema and systemic congestion, which are causing the infant's respiratory distress and poor feeding. This intervention follows the ABC (Airway, Breathing, Circulation) priority framework by alleviating the breathing difficulty caused by fluid overload.
Distractor Analysis:
Watch out for confusion! While obtaining a chest X-ray (Option 2) is important for diagnosis and monitoring, it is an assessment tool, not an immediate life-saving intervention. The clinical assessment already indicates severe fluid overload; treatment should not be delayed for further diagnostics.
Weighing the infant (Option 3) is crucial for monitoring, but the question states the infant has already gained 1.5 pounds. Weighing now would confirm the baseline for future monitoring but does not treat the current emergency.
Placing the infant in a high Fowler's position (Option 4) can help ease breathing by reducing pressure on the diaphragm and is a supportive measure. However, it does not address the underlying cause of the congestion—the excess fluid in the circulatory system and lungs.
Related Concepts: This scenario highlights the nursing process, specifically the Implementation phase where prioritizing actions based on patient acuity is critical. It also reinforces knowledge of pediatric assessment, where subtle signs like poor feeding and precise weight tracking are vital, and pharmacology, understanding the urgent role of diuretics in managing CHF exacerbations.
Concept Summary
Concept
Key Takeaway
Congestive Heart Failure (CHF) in Infants
Manifests as tachypnea, retractions, poor feeding, failure to thrive, and sudden weight gain from fluid retention.
Priority Setting (ABCs)
Airway and Breathing are top priorities. Interventions that directly improve respiratory status (like reducing pulmonary edema) take precedence.
Role of Diuretics (Furosemide)
First-line treatment for fluid overload in CHF. Reduces preload, decreases cardiac workload, and relieves pulmonary/systemic congestion.
Weight as an Assessment Tool
In pediatrics, daily weights are a sensitive measure of fluid balance. A gain of >1 oz/day in an infant or >0.5 kg/week in a child suggests fluid overload.
Assessment/Diagnostic: Confirms cardiomegaly and pulmonary congestion. Provides data but does not treat.
Moderate - Important but can follow initial treatment
Weigh the Infant
Assessment/Monitoring: Establishes a precise baseline for evaluating response to diuretic therapy.
Moderate - Should be done routinely, but not before treating acute distress
High Fowler's Position
Supportive Care: Uses gravity to improve lung expansion and ease work of breathing.
Moderate - Should be done concurrently with medication administration
Anatomy, Physiology & Pharmacology PointsPathophysiology: In CHF, the weakened heart muscle fails to eject blood effectively (decreased cardiac output). This leads to backup of blood into the pulmonary veins (pulmonary venous congestion) and systemic veins (systemic venous congestion). The resulting increased capillary pressure pushes fluid into the lungs (pulmonary edema) and interstitial spaces (peripheral edema, weight gain).
Pharmacology - Furosemide (Lasix): Acts on the ascending loop of Henle in the kidney to inhibit sodium and chloride reabsorption, causing profound diuresis. Key Point! Monitor for side effects: hypokalemia (low potassium), dehydration, and ototoxicity (especially with rapid IV administration).
Memory Tips
CHF Infant Signs: Think "Fails to Feed, Fights to Breathe, Fluid Gains" (The 3 F's and a G).
Priority Mnemonic: "Always Before Consulting" = Airway & Breathing interventions come before diagnostics (Consulting tests like X-ray).
High-Frequency NCLEX Topics
The NCLEX-RN heavily tests priority-setting and delegation. This question is a classic example of choosing a treatment over an assessment when the patient is in acute distress. Pediatric medication administration and assessment of fluid balance are also core tested areas.
Watch Out for Question Variations!
Shift from Symptom to Intervention: Instead of "which action is priority?", the question might ask: "The nurse administers furosemide. Which finding indicates the medication is effective?" (Answer: Decreased work of breathing, increased urine output, weight loss).
Shift to Complication: "The infant receiving IV furosemide develops muscle weakness and irregular heart rate. Which electrolyte imbalance should the nurse suspect?" (Answer: Hypokalemia).
Shift to Patient Education: "The mother of an infant with CHF is being discharged. Which instruction is most important regarding daily weight monitoring?" (Answer: Weigh the infant at the same time each day, using the same scale, and report a gain of more than 1 ounce per day).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a pediatric medical-surgical unit. A 3-month-old, "Baby Liam," is readmitted with a known history of Ventricular Septal Defect (VSD) and CHF. His mother reports he has been "breathing really fast," sweating during feeds, and taking only half his usual bottle volume. On assessment, you note nasal flaring, intercostal retractions, respiratory rate of 68/min, and audible crackles in the lung bases. His weight today is 1.5 lbs higher than his documented weight from last week's clinic visit.
Nursing Intervention Strategy:
Immediate Action (Priority): After notifying the provider of the acute findings, administer the prescribed IV furosemide promptly. Ensure correct dose calculation for pediatrics (mg/kg).
Concurrent Supportive Care: While preparing the medication, have a colleague place Liam in a semi-Fowler's to high Fowler's position (using an infant seat or elevated crib head) to maximize lung expansion. Provide oxygen therapy as ordered and monitor oxygen saturation via pulse oximetry.
Assessment & Monitoring: Obtain a precise weight using an infant scale (after the urgent medication is given) to serve as the new baseline. Strictly monitor intake and output (I&O), weighing diapers to measure urine output. Auscultate lung sounds before and after diuretic administration.
Family-Centered Care & Education: Explain all procedures to the parents in simple terms. Teach them to recognize signs of respiratory distress (nasal flaring, grunting, retractions) and the critical importance of daily weight monitoring at home.
Patient Safety and Precautions:
Medication Safety: Furosemide can cause significant fluid and electrolyte shifts. Monitor for signs of dehydration (poor skin turgor, sunken fontanelle) and hypokalemia (muscle weakness, lethargy, arrhythmias). Administer IV furosemide slowly as per policy to minimize ototoxicity risk.
Feeding Precautions: Infants in CHF fatigue easily. Implement strategies like small, frequent feedings, frequent burping, and using a nipple with a slower flow. Monitor for signs of aspiration.
Infection Control: Infants with CHF are more susceptible to respiratory infections. Practice strict hand hygiene and ensure all visitors are healthy.
Nursing Procedure & Medication FlowAdministering IV Furosemide to an Infant:
Verify & Calculate: Double-check the provider's order (e.g., furosemide 1 mg/kg IV now). Calculate the dose based on the infant's current weight in kilograms.
Prepare: Draw up the correct dose. For IV push, dilute as per hospital protocol (often with Normal Saline).
Administer: Connect to a patent IV line. Administer slowly (e.g., over 1-2 minutes) to prevent ototoxicity. Never give as a rapid bolus.
Monitor: Time the administration. Begin strict I&O monitoring. Expect diuresis to begin within 30-60 minutes. Assess lung sounds and respiratory effort post-administration.
Document: Document the time, dose, route, site, and the infant's immediate response (e.g., "IV furosemide administered via peripheral line in left hand. Infant resting quietly post-administration, respiratory rate decreased to 52/min").
A Word from Your Senior Nurse
"In the fast-paced world of pediatrics, your assessment skills are your superpower. For an infant who can't tell you they're short of breath, you must be a detective—noticing the subtle retractions, the sweaty forehead during a feed, and that concerning number on the scale. In an acute CHF exacerbation, the diuretic is your best friend. Giving it quickly and safely can turn the situation around. But remember, nursing is about the whole picture. While you're managing the crisis, don't forget the scared parents in the corner. A calm explanation and involving them in care can be as therapeutic as the medication. On the NCLEX and in practice, always link your knowledge: Pathophysiology (why is there fluid in the lungs?) → Symptom (why is the baby breathing fast?) → Intervention (what drug fixes the root cause?). That's how you become a nurse who doesn't just pass tests, but saves tiny lives."
Congestive Heart Failure — A chronic condition where the heart's pumping power is weaker than normal, leading to fluid backup (congestion) in the lungs and other body tissues.
Preload — The volume of blood in the ventricles at the end of diastole (just before contraction). In CHF, reducing preload with diuretics decreases the heart's workload.
Furosemide — A potent loop diuretic that inhibits sodium and chloride reabsorption in the kidney's loop of Henle, promoting fluid excretion. Used to treat edema and hypertension associated with CHF.
Pulmonary Edema — A life-threatening condition where fluid accumulates in the air sacs (alveoli) of the lungs, causing severe shortness of breath. A key complication of left-sided heart failure.
Intake and Output (I&O) — The precise measurement of all fluids a patient takes in (oral, IV) and puts out (urine, emesis, diarrhea). Critical for managing fluid balance in patients with CHF, renal failure, or on diuretic therapy.
