Calcium plays a crucial role in numerous bodily functions, including bone formation, muscle contraction, nerve signaling, and blood clotting. Maintaining proper calcium levels is essential for overall health and well-being. This article explores hypocalcemia (low calcium levels) and hypercalcemia (high calcium levels), focusing on nursing diagnoses, interventions, and care plans.
Understanding Calcium Balance
Normal serum calcium levels typically range from 8.5 to 10.5 mg/dL (2.1 to 2.6 mmol/L). Hypocalcemia occurs when levels fall below 8.5 mg/dL, while hypercalcemia is diagnosed when levels exceed 10.5 mg/dL. It’s important to note that specific reference ranges may vary slightly between laboratories.
Causes of Hypocalcemia
- Hypoparathyroidism
- Vitamin D deficiency
- Chronic kidney disease
- Malabsorption syndromes
- Certain medications (bisphosphonates, diuretics)
Causes of Hypercalcemia
- Hyperparathyroidism
- Malignancies
- Excessive vitamin D intake
- Prolonged immobilization
- Certain medications (thiazide diuretics, lithium)
Signs and Symptoms
Hypocalcemia
- Muscle cramps and spasms
- Numbness and tingling in extremities
- Seizures
- Tetany
- Cardiac arrhythmias
- Positive Chvostek’s and Trousseau’s signs
Hypercalcemia
- Fatigue and weakness
- Confusion and altered mental status
- Nausea and vomiting
- Constipation
- Polyuria and polydipsia
- Cardiac arrhythmias
Nursing Care Plans for Hypocalcemia and Hypercalcemia
1. Imbalanced Nutrition: Less Than Body Requirements

- Implement fall prevention measures (e.g., bed in low position, clear walkways).
Rationale: Reduces the risk of falls and subsequent injuries. - Assess for signs of tetany and seizure activity regularly.
Rationale: Allows for early detection and prompt intervention. - Educate the patient and family about safety precautions and seizure management.
Rationale: This helps the patient and family to prevent and manage potential complications. - Ensure proper padding of bed rails and removal of hazardous objects.
Rationale: Minimizes the risk of injury during potential seizure episodes. - Administer anticonvulsant medications as prescribed.
Rationale: Helps prevent and manage seizures associated with severe hypocalcemia.
Desired Outcomes:
- The patient will remain free from falls and injuries during hospitalization.
- The patient and family will demonstrate an understanding of safety measures and seizure precautions.
- The patient will show a reduction in tetany and seizure episodes.
3. Ineffective Tissue Perfusion
Nursing Diagnosis Statement: Ineffective tissue perfusion related to altered cardiac function secondary to hypercalcemia, as evidenced by ECG changes, fatigue, and altered mental status.
Related Factors/Causes:
- Calcium deposits in blood vessels
- Cardiac arrhythmias
- Dehydration associated with hypercalcemia
Nursing Interventions and Rationales:
- Monitor vital signs and cardiac rhythm regularly.
Rationale: Allows for early detection of cardiovascular complications. - Administer IV fluids as ordered to promote calcium excretion and improve hydration.
Rationale: Helps lower serum calcium levels and improves tissue perfusion. - Position the patient with the head of the bed elevated to improve cardiac function.
Rationale: Enhances venous return and reduces cardiac workload. - Assess peripheral pulses and capillary refill.
Rationale: Provides information about peripheral circulation and tissue perfusion. - Administer medications to lower calcium levels as prescribed (e.g., bisphosphonates, calcitonin).
Rationale: Helps correct hypercalcemia and improve cardiac function.
Desired Outcomes:
- The patient will demonstrate improved tissue perfusion as evidenced by stable vital signs and improved mental status.
- The patient will show a reduction in ECG abnormalities associated with hypercalcemia.
- The patient will report decreased fatigue and improved energy levels.
4. Acute Confusion
Nursing Diagnosis Statement: Acute confusion related to electrolyte imbalance secondary to hypercalcemia, as evidenced by disorientation, altered level of consciousness, and impaired cognitive function.
Related Factors/Causes:
- Elevated serum calcium levels affecting brain function
- Dehydration associated with hypercalcemia
- Underlying medical conditions (e.g., malignancy, hyperparathyroidism)
Nursing Interventions and Rationales:
- Perform frequent neurological assessments, including level of consciousness and orientation.
Rationale: Allows for early detection of changes in mental status and cognitive function. - Provide a calm, quiet environment with familiar objects.
Rationale: Reduces confusion and promotes a sense of security. - Use simple, clear communication and reorient the patient frequently.
Rationale: Helps improve comprehension and reduces anxiety. - Encourage family involvement in care and communication.
Rationale: Provides familiar support and aids in reorientation. - Monitor and correct electrolyte imbalances as ordered.
Rationale: Addresses the underlying cause of confusion and promotes cognitive improvement.
Desired Outcomes:
- The patient will demonstrate improved mental status and orientation.
- The patient will show a reduction in confused behaviors and improved cognitive function.
- The patient’s serum calcium levels will return to normal range.
5. Deficient Knowledge
Nursing Diagnosis Statement: Deficient knowledge related to lack of information about calcium imbalance, its causes, and management, as evidenced by verbalization of misconceptions and questions about the condition.
Related Factors/Causes:
- Lack of exposure to information about calcium disorders
- Misinterpretation of health information
- Cognitive limitations
