A nurse is caring for a client with hyperparathyroidism who is scheduled for a parathyroidectomy. Which nursing intervention should be the priority in the immediate postoperative period?

The nurse is monitoring a client who underwent parathyroidectomy 4 hours ago for hyperparathyroidism.
해설
After parathyroidectomy, the most critical complication is hypocalcemia due to inadvertent removal or damage to the parathyroid glands, which can lead to life-threatening tetany and laryngospasm.

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention following a parathyroidectomy for hyperparathyroidism. The core pathophysiological principle is the sudden drop in Parathyroid hormone (PTH) levels post-surgery. PTH is the primary regulator of serum calcium. Its abrupt removal can cause a rapid and severe decrease in serum calcium (hypocalcemia), which is a life-threatening emergency due to the risk of neuromuscular irritability, tetany, and laryngospasm.

Answer Rationale: Key Point! The priority in the immediate postoperative period is Assess for signs and symptoms of hypocalcemia. This is because hypocalcemia is the most acute, dangerous, and common complication following this specific surgery. Early signs include perioral and digital numbness/tingling (paresthesias), muscle twitching (Chvostek's sign, Trousseau's sign), and anxiety. Untreated, it can progress to tetany, seizures, and fatal laryngospasm. Monitoring for this complication directly addresses the patient's highest safety risk (Airway, Breathing, Circulation - ABCs).

Distractor Analysis:
Watch out for confusion! While monitoring for infection (Option 1) is a standard postoperative intervention for any surgery, it is not the immediate priority. The risk of symptomatic infection typically develops over days, not within the first 4 hours. The threat of hypocalcemia is more imminent.
Watch out for confusion! Encouraging early ambulation (Option 3) is important for preventing DVT (Deep vein thrombosis) and atelectasis, but it is a general postoperative goal, not the specific, life-threatening priority for this patient population in the first few hours.
Watch out for confusion! Administering pain medication (Option 4) is essential for patient comfort and recovery, but comfort, while important, is secondary to managing an immediate physiological threat to life (hypocalcemia). Pain management is part of comprehensive care but does not supersede airway and breathing safety.

Related Concepts: Post-parathyroidectomy care also involves monitoring for hemorrhage (which can cause airway compromise via hematoma) and recurrent laryngeal nerve injury (hoarseness, weak voice). However, in the context of hyperparathyroidism, where parathyroid tissue is overactive and often enlarged, the manipulation or removal of glands makes hypocalcemia the paramount concern. Nurses must be prepared to administer IV calcium gluconate or calcium chloride for severe symptoms.
Concept Summary
ConceptDescriptionNursing Implication
HyperparathyroidismOverproduction of PTH leading to hypercalcemia.Pre-op: Monitor for bone pain, kidney stones, fatigue. Post-op: Watch for drastic shift to hypocalcemia.
ParathyroidectomySurgical removal of parathyroid gland(s).Primary concern: Acute hypocalcemia. Assess for tetany, laryngospasm.
HypocalcemiaLow serum calcium < 8.5 mg/dL (Normal: 8.5-10.5 mg/dL).Monitor for paresthesias, Chvostek's sign, Trousseau's sign, seizures. Have IV calcium available.
Parathyroid Hormone (PTH)Regulates calcium and phosphate balance. Increases blood calcium.Removal → PTH drops → Calcium plummets. Understand the inverse relationship with phosphate.

Post-Op ComplicationKey Signs & SymptomsTiming / PriorityNursing Action
Hypocalcemia (Priority)Perioral/finger tingling, muscle cramps, Chvostek's sign (facial twitch), Trousseau's sign (carpopedal spasm), laryngospasm (stridor).Immediate (first 24-72 hrs). HIGHEST PRIORITY.Frequent assessment. Administer IV/PO calcium supplements. Ensure airway patency.
Hemorrhage / HematomaNeck swelling, difficulty breathing (dyspnea), feeling of pressure, tachycardia, hypotension.Immediate (first few hours). Also high priority (ABCs).Assess neck and airway. Notify surgeon immediately. Prepare for possible evacuation.
Recurrent Laryngeal Nerve InjuryHoarseness, weak voice, vocal cord paralysis.Noted upon awakening or soon after.Assess voice quality. Reassure patient (may be temporary). Speech therapy referral.
InfectionFever, redness, warmth, purulent drainage, increased pain at incision.Develops over days (not immediate).Standard post-op wound care and monitoring.

Anatomy, Physiology & Pharmacology Points
  • Anatomy: The four tiny parathyroid glands are located on the posterior surface of the thyroid gland. Their small size and variable location make them susceptible to accidental removal or devascularization during thyroid or parathyroid surgery.
  • Physiology: PTH raises blood calcium by: 1) Stimulating bone resorption (releasing Ca2+), 2) Increasing renal reabsorption of calcium, and 3) Activating vitamin D to increase intestinal calcium absorption. It also decreases phosphate reabsorption.
  • Pharmacology: Emergency treatment for symptomatic hypocalcemia is IV calcium gluconate (preferred as it is less irritating) or calcium chloride. Administer slowly while monitoring the ECG for bradycardia or QT interval shortening. Oral calcium (e.g., calcium carbonate) and vitamin D (e.g., calcitriol) are used for chronic management.

Memory Tips
  • Mnemonic for Hypocalcemia Signs: "Convulsions, Arrhythmias, Tetany, Stridor, Chvostek/Trousseau signs" (CATS Catching Twitches).
  • Think "The Calcium Crash": After removing the "calcium-raising" glands (parathyroids), the patient's calcium levels can crash. Your job is to catch the fall.
  • Priority Rule: In post-parathyroidectomy, think Airway (A) first. Laryngospasm from hypocalcemia is an airway emergency. Therefore, assessing for hypocalcemia is assessing for airway risk.

High-Frequency NCLEX Topics The NCLEX-RN frequently tests priority-setting and complication recognition for specific surgeries. Parathyroidectomy is a classic example where you must know the #1 complication (hypocalcemia) and its signs. Expect questions that ask: "Which finding requires immediate intervention?" or "Which client should the nurse see first?" The answer will often involve symptoms of neuromuscular irritability.
Watch Out for Question Variations!
  • Symptom Identification: "A client 6 hours post-parathyroidectomy reports tingling around the mouth and in the fingers. The nurse should recognize this as indicative of..." (Answer: Hypocalcemia).
  • Priority Action: "The nurse observes a post-parathyroidectomy client developing carpopedal spasm (Trousseau's sign). What is the nurse's priority action?" (Answer: Prepare to administer IV calcium as prescribed and ensure a patent airway).
  • Patient Education: "What discharge teaching is most important for a client after parathyroidectomy for hyperparathyroidism?" (Answer: Teach signs of hypocalcemia and the importance of calcium and vitamin D supplements).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a surgical unit. Mr. Johnson, 58, is 4 hours post-op from a parathyroidectomy for primary hyperparathyroidism. His vital signs are stable, but he is anxious and says, "My lips and fingers feel all tingly and pins-and-needles."

Nursing Intervention Strategy:
  1. Immediate Assessment (ABCs):
    • Airway & Breathing: Listen for stridor, hoarseness, or any sign of respiratory distress. Ask if he feels tightness in his throat.
    • Neuromuscular: Check for Chvostek's sign (tap facial nerve) and Trousseau's sign (inflate blood pressure cuff). Assess for muscle twitching.
    • Vital Signs & Labs: Check vital signs. Anticipate an order for a STAT serum calcium and ionized calcium level. Compare to pre-op levels.
  2. Immediate Action:
    • Notify the surgeon/provider immediately with your assessment findings.
    • Stay with the patient, provide reassurance to decrease anxiety (which can exacerbate symptoms).
    • Ensure IV access is patent.
  3. Treatment & Monitoring:
    • Prepare for administration of IV calcium (e.g., calcium gluconate) as ordered. Administer slowly via pump, monitoring the ECG.
    • After treatment, re-assess symptoms and monitor for recurrence.
    • Initiate oral calcium and vitamin D supplements as ordered for ongoing management.
Patient Safety and Precautions:
  • IV Calcium Administration: Administer slowly (per protocol, often over 10-30 minutes) through a large, patent vein. Infiltration can cause severe tissue necrosis. Monitor for bradycardia and hypotension.
  • Airway Precautions: Have emergency equipment (suction, ambu bag, intubation tray) readily available. Laryngospasm is a true emergency.
  • Fall Risk: Muscle cramps and paresthesias increase fall risk. Implement fall precautions.

Nursing Procedure & Medication Flow Procedure: Assessing for Hypocalcemia Post-Parathyroidectomy 1. Every 1-2 hours for first 24 hours: Ask about perioral/finger numbness or tingling. 2. Perform Neuromuscular Checks: - Chvostek's Sign: Tap the facial nerve just anterior to the ear. A positive sign is ipsilateral twitching of the facial muscles. - Trousseau's Sign: Inflate a blood pressure cuff above systolic pressure for 3 minutes. A positive sign is flexion of the wrist and metacarpophalangeal joints, extension of the fingers, and thumb adduction (carpopedal spasm). 3. Monitor Labs: Track serum calcium, albumin (for corrected calcium), and phosphate levels.
Medication: IV Calcium Gluconate Administration - Action: Rapidly increases ionized calcium levels in the blood. - Dose/Route: Typically 1-2 grams (10-20 mL of 10% solution) in 50-100 mL D5W IV over 10-30 minutes. - Nursing Considerations: 1. Use a large-bore IV in a large vein. 2. Use an infusion pump. Do not bolus. 3. Monitor ECG continuously for arrhythmias (bradycardia, shortened QT). 4. Assess for signs of extravasation (pain, redness). If suspected, stop infusion immediately. 5. Have calcium chloride available for more severe cases (contains more elemental calcium but is more vesicant).
A Word from Your Senior Nurse "Nursing is not just about carrying out physician orders — it's about being the frontline guardian for your patients! In this scenario, Mr. Johnson's complaint of 'tingling' is your early warning bell. You are the one at the bedside who connects that symptom to the pathophysiological 'calcium crash.' By acting swiftly on that assessment, you prevent a tingling sensation from escalating into a life-threatening laryngospasm. When studying for your boards, don't just memorize 'hypocalcemia after parathyroidectomy.' Picture Mr. Johnson. Ask yourself, 'What would I look for? What would I do first?' That clinical mindset is what makes a safe nurse and will shine through on your NCLEX."
