A nurse is caring for a 60-year-old client with heart failure who has developed ascites and peripheral edema. The client's serum albumin level is 2.1 g/dL (normal: 3.5-5.0 g/dL) and sodium level is 128 mEq/L (normal: 136-145 mEq/L). Which nursing intervention should be the priority?

Fluid restriction is the priority to manage ascites and dilutional hyponatremia in cirrhosis by preventing further fluid accumulation. Other options may worsen the condition or are not immediate priorities.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a patient with heart failure (HF) complicated by ascites, edema, and hyponatremia. The core pathophysiology is fluid overload. In HF, the heart's pumping ability is compromised, leading to decreased renal perfusion. This activates the renin-angiotensin-aldosterone system (RAAS), causing sodium and water retention. The low serum albumin (2.1 g/dL) contributes to decreased oncotic pressure, pulling fluid from the blood vessels into the interstitial spaces (ascites, edema). The hyponatremia (128 mEq/L) in this context is typically dilutional, meaning there is too much water relative to sodium, not a true sodium deficit.

Answer Rationale: Key Point! The priority is to manage the fluid overload, which is the underlying cause of the ascites, edema, and dilutional hyponatremia. Fluid restriction directly addresses this by reducing total body water, which can help improve symptoms, decrease ascites/edema, and gradually correct the sodium level by reducing dilution. This is a fundamental, first-line nursing intervention in managing advanced HF with volume overload.

Distractor Analysis: Watch out for confusion! Option ①, "Administer high-sodium IV fluids," is dangerous. Giving sodium intravenously to a patient with fluid overload and dilutional hyponatremia will worsen the edema and ascites by pulling more fluid into the vascular space and then leaking out. It does not address the root cause of too much water.
Option ③, "Encourage increased protein intake," addresses the low albumin but is not the immediate priority. While improving nutrition is important, it is a long-term strategy. The acute problems of severe fluid overload and symptomatic hyponatremia require more urgent intervention.
Option ④, "Position the client in Trendelenburg position," is contraindicated. The Trendelenburg position (head down, feet up) would increase venous return to an already failing heart, potentially worsening pulmonary congestion and respiratory distress in a patient with heart failure.

Related Concepts: This scenario integrates concepts of cardiovascular nursing (HF management), fluid and electrolyte balance (hyponatremia), and oncotic pressure. Understanding the difference between dilutional (hypervolemic) hyponatremia (treated with fluid restriction/diuretics) and depletional (hypovolemic) hyponatremia (treated with saline replacement) is critical for safe practice.

Concept Summary

Concept	Explanation	Clinical Implication
Dilutional Hyponatremia	Low serum sodium due to excess total body water (hypervolemia). Common in HF, cirrhosis, SIADH.	Treatment: Fluid restriction, diuretics. Do not give saline rapidly.
Fluid Restriction	A therapeutic limit on daily oral/IV fluid intake (e.g., 1-1.5 L/day).	Priority intervention to reduce volume overload in HF, manage ascites, and correct dilutional imbalances.
Oncotic Pressure	Pressure exerted by plasma proteins (mainly albumin) that holds fluid within blood vessels.	Low albumin ( 임상 시나리오 Nursing Clinical Practice Guide Clinical Scenario: You are assigned to Mr. Johnson, a 60-year-old with a history of ischemic cardiomyopathy admitted for worsening shortness of breath and abdominal distension. On assessment, you note 3+ pitting edema in his lower extremities, a distended abdomen with shifting dullness (ascites), and crackles in the lung bases. His daily weight has increased by 4 kg in 3 days. Nursing Intervention Strategy: Assessment: Obtain accurate daily weights (same scale, same time, same clothing), strict I&O (Intake and Output), monitor respiratory status, assess edema/ascites, and review lab values (Na+, BUN, Creatinine, Albumin). Planning & Implementation: Priority: Fluid Management: Collaborate with the provider to establish a strict fluid restriction order (e.g., 1500 mL/24hr). Educate the patient and family. Provide ice chips, offer frequent oral care, and space fluids throughout the day. Medication Administration: Administer prescribed diuretics (e.g., IV furosemide). Monitor for effectiveness (increased urine output) and side effects (electrolyte depletion, ototoxicity). Positioning: Position in High Fowler's or semi-Fowler's to ease breathing and reduce venous return to the heart. Never use Trendelenburg. Nutrition: Consult dietary for a low-sodium diet. While protein supplementation is beneficial for albumin, it is integrated into the overall nutritional plan, not an emergency measure. Evaluation: Monitor for decreased edema, weight loss, improved breath sounds, and a gradual increase in serum sodium toward normal. Patient Safety and Precautions: Hyponatremia Correction: Correct sodium levels slowly (< 10-12 mEq/L in 24 hours) to avoid osmotic demyelination syndrome (central pontine myelinolysis). Diuretic Therapy: Monitor for hypokalemia, which can precipitate arrhythmias. Assess for signs of dehydration (e.g., orthostatic hypotension) if diuresis is too aggressive. Fall Risk: Edema and fluid shifts can affect balance. Implement fall precautions. Nursing Procedure & Medication Flow Implementing Fluid Restriction: Calculate the 24-hour fluid allotment (e.g., 1500 mL). Divide allotment into shifts (e.g., Day shift: 700 mL, Evening: 500 mL, Night: 300 mL). Mark a large, clear pitcher with time markers. All oral fluids, ice chips (melted volume), IV flushes, and IV medications in fluid vehicles count toward the total. Record all intake meticulously on the I&O sheet. Educate the patient: "All liquids count, including soup, Jell-O, and ice cream." Administering IV Furosemide: Route: IV push (slowly over 1-2 minutes) or IV infusion. Monitoring: Monitor urine output hourly. Expect a significant diuresis within 30-60 minutes. Precaution: Assess hearing before and after (ototoxicity risk). Administer potassium supplements or potassium-sparing diuretics as ordered. A Word from Your Senior Nurse "In heart failure, we are constantly walking a tightrope between 'too wet' and 'too dry.' Your keen assessment skills are the safety net. That daily weight is your best friend—a 2-3 pound gain overnight is a red flag for fluid overload long before the crackles appear. When you see hyponatremia with edema, your brain should immediately shout 'Dilutional! Restrict fluids!' Memorizing lab values is good, but understanding the story they tell about your patient's physiology is what makes you an excellent nurse. This mindset will guide you safely through NCLEX questions and, more importantly, through your night shifts with critically ill patients." 핵심 개념 Dilutional Hyponatremia — Low serum sodium concentration due to an excess of total body water relative to sodium content. Common in conditions like heart failure, cirrhosis, and renal failure where water retention dilutes sodium levels. Fluid Restriction — A therapeutic limitation on a patient's daily fluid intake, prescribed to manage conditions involving fluid overload, such as heart failure, severe hyponatremia, or renal failure. Oncotic Pressure — The osmotic pressure exerted by plasma proteins, primarily albumin, within blood vessels. It helps retain fluid in the intravascular space. Low levels lead to edema and ascites. Renin-Angiotensin-Aldosterone System — A hormone system that regulates blood pressure and fluid balance. In heart failure, it is inappropriately activated, leading to sodium and water retention, which exacerbates fluid overload. Trendelenburg Position — A position where the patient's body is laid flat on the back with the feet higher than the head. It is generally contraindicated in heart failure as it increases venous return and preload, potentially worsening pulmonary edema. 마이메르시로 국가고시 완벽 대비 기출문제와 상세 해설을 무료로. 내 약점을 분석하고 진도를 관리하며 더 똑똑하게 공부하세요. 무료로 시작하기 App Store Google Play 학습 참고용입니다. 실제 임상은 최신 지침과 소속 기관 프로토콜을 따르세요.
