A nurse is caring for a postpartum client diagnosed with subinvolution. Which nursing intervention should be the priority?

해설
Fundal massage and monitoring lochia are priority interventions for subinvolution to promote uterine contraction and assess bleeding. Other interventions are supportive but secondary.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a postpartum patient with subinvolution. Subinvolution refers to the failure of the uterus to return to its non-pregnant size and condition (involution) at the expected rate. The primary pathophysiological problem is inadequate uterine contraction, which can lead to uterine atony (lack of muscle tone), retained placental fragments, and potentially life-threatening postpartum hemorrhage (PPH). The priority nursing focus is therefore on promoting uterine contraction and preventing/controlling hemorrhage.

Answer Rationale: Key Point! The correct answer is ③ Perform fundal massage and monitor lochia characteristics. This is the direct, immediate action to address the core problem. Fundal massage stimulates the uterine muscle to contract, helping to expel clots and reduce bleeding. Simultaneously, monitoring lochia (amount, color, consistency, odor) provides critical assessment data to determine the effectiveness of interventions and detect signs of infection or excessive bleeding. This intervention aligns with the ABC (Airway, Breathing, Circulation) priority framework, addressing the "C" (Circulation/hemorrhage) threat.

Distractor Analysis:
Watch out for confusion! ① Encourage early ambulation and frequent position changes: While ambulation promotes circulation and prevents complications like deep vein thrombosis (DVT), it is a general postpartum measure and does not directly address the urgent problem of uterine atony and potential hemorrhage in subinvolution.
Watch out for confusion! ② Administer prescribed antibiotics as ordered: Antibiotics may be indicated if subinvolution is caused by or leads to endometritis (uterine infection). However, this is a dependent nursing action (requires a physician's order) and is not the priority intervention. The first action is to assess and attempt to stimulate uterine contraction. Infection control is important but secondary to controlling active bleeding.
Watch out for confusion! ④ Provide emotional support and patient education: This is a vital component of holistic nursing care, especially for a mother who may be anxious about her recovery. However, in the context of a potential physiological emergency (hemorrhage), psychosocial interventions follow after stabilizing the patient's physical condition.

Related Concepts: Subinvolution is often associated with factors like overdistended uterus (multiple gestation, polyhydramnios), retained placental fragments, or uterine infection. Nursing management follows the nursing process: assess (fundal height, firmness, lochia), intervene (massage, administer uterotonics like oxytocin), and evaluate (reduction in bleeding, firm fundus).

InvolutionNormal process of the uterus shrinking back to pre-pregnancy size (takes ~6 weeks).Monitor fundal height (descends 1-2 cm/day).
SubinvolutionDelayed or failed involution; uterus remains enlarged and boggy.Priority: Fundal massage, assess for hemorrhage.
Fundal MassageManual stimulation of the uterine fundus to promote contraction.Perform with one hand on fundus, one hand above symphysis pubis. Stop when firm.

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on the postpartum unit. A patient, 12 hours after a vaginal delivery, calls you to her room stating she feels a "gush" of blood. You find her peripad saturated with bright red blood. On assessment, her uterus is soft and palpable above the umbilicus (should be at or below), and she has moderate to heavy lochia rubra with small clots.

Nursing Intervention Strategy: 1. Immediate Action (Priority): Don gloves. Place one hand just above the symphysis pubis to support the uterus, and use the other hand to firmly massage the uterine fundus in a circular motion. Continue until the uterus becomes firm and globular. Note the amount of bleeding. 2. Assessment: While massaging, ask a colleague or call for help to: Assess vital signs (BP, HR for signs of shock), estimate blood loss (weigh pads/chux), and check for bladder distention (a full bladder displaces the uterus and prevents contraction). 3. Implementation: After the uterus is firm, continue to monitor fundal tone and lochia every 15 minutes. Ensure IV access is patent. Administer ordered uterotonic medication (e.g., oxytocin IV infusion). Encourage the patient to empty her bladder. 4. Evaluation & Communication: Document the fundal firmness, location, lochia characteristics, and patient response. Report findings to the primary provider. If bleeding persists despite massage and medication, prepare for further interventions (e.g., additional medications, examination for lacerations, possible OR for D&C).

Patient Safety and Precautions: * Key Point! Never perform fundal massage on a firm uterus, as this can cause uterine inversion or trauma. * During massage, monitor for signs of orthostatic hypotension or worsening bleeding. * Be aware of medication contraindications: e.g., Methergine can cause severe hypertension. Nursing Procedure & Medication Flow Fundal Massage Procedure: 1. Explain the procedure to the patient. 2. Ensure privacy, position patient supine with knees slightly flexed. 3. Palpate the uterus to assess firmness and location. 4. If boggy, place stabilizing hand suprapubically. With dominant hand on fundus, massage firmly but gently until firm (usually 15-30 seconds). 5. Dispose of soiled linens, perform hand hygiene, document.
Oxytocin (Pitocin) Administration: * Common postpartum dose: 10-40 units in 1 liter of IV fluid (e.g., Lactated Ringer's). * Infuse via an IV pump. Monitor for adverse effects: water intoxication (headache, nausea, confusion from antidiuretic effect), tachycardia, uterine hyperstimulation (prolonged, tetanic contractions). A Word from Your Senior Nurse "In postpartum nursing, your hands are one of your most important assessment tools. Feeling that uterus change from soft and boggy to firm and contracted under your hand is an immediate sign that your intervention is working and you're preventing a hemorrhage. Always think 'Tone, Trauma, Tissue, Thrombin' when you see postpartum bleeding. And remember, while emotional support is crucial, you can't provide effective counseling if your patient is bleeding out. Master the physical skills first—they save lives. This 'physiological before psychosocial' priority thinking is exactly what the NCLEX tests."

핵심 개념

  • Subinvolution — The failure of the uterus to return to its non-pregnant size and state at the expected rate after childbirth, often leading to postpartum hemorrhage.
  • Fundal Massage — A manual nursing technique used to stimulate uterine contractions by applying circular pressure to the uterine fundus, primarily to treat uterine atony and control postpartum bleeding.
  • Lochia — The normal postpartum vaginal discharge consisting of blood, mucus, and uterine tissue. It progresses through three stages: rubra (red), serosa (pink/brown), and alba (white/yellow).
  • Uterine Atony — Lack of uterine muscle tone after delivery, which is the most common cause of early postpartum hemorrhage. It prevents the clamping of spiral arteries at the placental site.
  • Postpartum Hemorrhage — Excessive bleeding after childbirth, defined as blood loss greater than 500 mL for a vaginal delivery or 1000 mL for a cesarean section. Early PPH occurs within the first 24 hours.
