A nurse is caring for a client with hypoparathyroidism who is showing muscle twitching, tingling in fingers, and positive Chvostek's sign. Which nursing intervention should the nurse implement first?

해설
In hypoparathyroidism with acute hypocalcemia, ensuring patent IV access and preparing for IV calcium administration is the priority intervention as it provides the most rapid correction of severe hypocalcemia and prevents life-threatening complications.

심화 해설

Core Nursing Explanation Key Concept Analysis: This question assesses the priority nursing intervention for a patient with Hypoparathyroidism experiencing acute Hypocalcemia. Hypoparathyroidism leads to insufficient Parathyroid hormone (PTH) secretion, which is crucial for maintaining serum calcium levels. The symptoms described—muscle twitching, paresthesia (tingling), and a positive Chvostek's sign (facial muscle twitching upon tapping the facial nerve)—are classic signs of neuromuscular irritability due to low ionized calcium. This is a potential medical emergency as severe hypocalcemia can progress to Tetany, laryngospasm, seizures, and life-threatening cardiac arrhythmias.

Answer Rationale: Key Point! The priority in acute, symptomatic hypocalcemia is the rapid correction of the serum calcium level to prevent life-threatening complications. The most effective and immediate route for calcium administration is intravenous (IV). Therefore, the nurse's first action should be to ensure patent IV access and prepare for IV calcium administration. This intervention directly addresses the underlying pathophysiology and is the standard of care for managing acute hypocalcemic symptoms.

Distractor Analysis:
Watch out for confusion! Option 1 (Administer oral calcium supplements) is appropriate for chronic, mild, or asymptomatic hypocalcemia but is not the priority for acute, symptomatic presentation. Oral absorption is slower and less reliable in an emergency situation.
• Option 2 (Monitor cardiac rhythm continuously) is a critical and necessary intervention because hypocalcemia can cause prolonged QT intervals and serious arrhythmias like Torsades de pointes. However, monitoring alone does not treat the root cause. It is an important concurrent action but follows securing the means for definitive treatment (IV access).
• Option 3 (Prepare for emergency tracheostomy) is a potential intervention for the most severe complication of hypocalcemia: laryngospasm leading to airway obstruction. While the nurse must be vigilant for signs of respiratory distress, preparing for a surgical airway is not the first intervention. The priority is to administer IV calcium to reverse the hypocalcemia and potentially prevent laryngospasm from occurring.

Related Concepts: This scenario integrates endocrine pathophysiology (PTH function), electrolyte imbalance management, and nursing prioritization using frameworks like ABCs (Airway, Breathing, Circulation) and Maslow's Hierarchy of Needs. Treating the physiological threat (severe electrolyte imbalance) takes precedence. Concept SummaryHypoparathyroidism: Deficiency of PTH → leads to hypocalcemia and hyperphosphatemia.
Acute Hypocalcemia Signs: Neuromuscular irritability: perioral/finger tingling, muscle cramps, Chvostek's sign, Trousseau's sign (carpopedal spasm with blood pressure cuff inflation), tetany, seizures.
Priority Intervention: Secure IV access for rapid calcium gluconate or chloride administration.
Key Monitoring: Cardiac rhythm (for prolonged QT), respiratory status (for laryngospasm), and serial serum calcium levels.
Side-by-Side Comparison!
ConditionKey Lab FindingPrimary Symptom FocusAcute Treatment Priority
Hypocalcemia (e.g., from Hypoparathyroidism)Serum Ca < 8.5 mg/dL (Normal: 8.5-10.5 mg/dL)Neuromuscular irritability (twitching, tetany)IV Calcium administration
Hypercalcemia (e.g., from Hyperparathyroidism)Serum Ca > 10.5 mg/dL"Stones, Bones, Groans, Psychiatric Overtones" (renal stones, bone pain, constipation, confusion)IV Fluids (hydration) and loop diuretics
Anatomy, Physiology & Pharmacology PointsPhysiology: PTH increases blood calcium by: 1) Stimulating bone resorption, 2) Increasing renal calcium reabsorption, and 3) Activating vitamin D to increase intestinal calcium absorption.
Pharmacology - IV Calcium: Calcium gluconate is preferred over chloride for peripheral IV lines as it is less irritating. Administer slowly (as per protocol, often over 10-20 minutes) while monitoring the patient's heart rate and IV site. Rapid infusion can cause bradycardia, hypotension, or cardiac arrest.
Memory TipsHypo-Calcemia Signs: Think "Convulsions, Arrhythmias, Tetany, Spasms" (CATS).
Chvostek vs. Trousseau: Chvostek is tapping the cheek. Trousseau is inflating the BP cuff.
High-Frequency NCLEX Topics NCLEX loves to test electrolyte imbalances! For hypocalcemia, know: 1) The classic signs (Chvostek's, Trousseau's), 2) That it prolongs the QT interval on ECG, and 3) That IV calcium is the treatment for acute symptoms. Prioritization questions often pit monitoring against treating the cause. Watch Out for Question Variations! • Instead of asking for the first intervention, the question might ask: "The nurse should monitor for which life-threatening complication?" (Answer: Laryngospasm or Cardiac arrhythmia).
• It could present with an abnormal lab value (e.g., Calcium = 7.0 mg/dL) and ask for the associated finding.
• It might combine hypocalcemia with a post-thyroidectomy patient (a common cause of accidental parathyroid removal).

임상 시나리오

Nursing Clinical Practice Guide Clinical Scenario: You are the nurse on a medical-surgical unit. A 58-year-old female patient, status post total thyroidectomy 2 days ago, reports numbness around her mouth and tingling in her hands. Upon assessment, you note mild twitching of her facial muscles when you lightly tap her cheek (positive Chvostek's sign). Her vital signs are stable, but she appears anxious.

Nursing Intervention Strategy:
1. Immediate Action (Assessment & Intervention): Stay with the patient. Assess airway patency and respiratory effort for any stridor or shortness of breath. Check for a patent IV line. If no IV is present or it is not patent, insert a new peripheral IV catheter immediately. Notify the provider STAT and anticipate an order for IV calcium gluconate.
2. Safety & Monitoring: Place the patient on continuous cardiac monitoring to observe for QT prolongation or arrhythmias. Ensure emergency equipment (including airway supplies and IV calcium) is readily available at the bedside. Keep the bed in a low position with side rails up due to seizure risk.
3. Medication Administration: When the order for IV calcium gluconate is received, administer it slowly through a patent IV line, typically over 10-20 minutes as ordered. Monitor for bradycardia, hypotension, and signs of extravasation (tissue necrosis can occur).
4. Patient Education & Follow-up: Once stable, educate the patient on chronic hypoparathyroidism management: lifelong oral calcium and vitamin D supplements, signs of hypo/hypercalcemia to report, and the importance of follow-up lab work.

Patient Safety and Precautions:
IV Calcium Administration: Never give IV calcium rapidly. Do not mix with bicarbonate-containing solutions (causes precipitation). Use caution in patients on digoxin, as calcium potentiates digoxin toxicity.
Airway Vigilance: Any complaint of throat tightness or difficulty breathing should trigger an immediate rapid response/code activation, as it may indicate laryngospasm. Nursing Procedure & Medication Flow Procedure: Administering IV Calcium Gluconate for Acute Hypocalcemia
1. Verify provider's order (drug, dose, route, rate).
2. Perform hand hygiene and don PPE.
3. Check IV site for patency and absence of redness/swelling.
4. Obtain calcium gluconate vial. Check for precipitate.
5. Administer slowly via IV push or infusion pump as ordered (e.g., 1-2 mL/min).
6. Monitor vital signs (especially heart rate and BP) before, during, and after administration.
7. Observe patient for therapeutic effect (decrease in twitching/tingling) and adverse effects (flushing, nausea, bradycardia).
8. Document administration, patient response, and any interventions. 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, recognizing that tingling and a positive Chvostek's sign are red flags for acute hypocalcemia is critical. Your quick thinking to secure IV access isn't just a task; it's the lifeline that allows for rapid treatment to prevent a seizure or a closed airway. When studying for your boards, don't just memorize 'IV calcium for hypocalcemia.' Connect it to the real patient: their fear, the twitching you see, and the immediate action you must take. That clinical mindset is what saves lives and makes you an excellent nurse."
