hypercalcemia - Nursing Case Study

Pathophysiology

• Primary mechanism: Increased parathyroid hormone (PTH) secretion leads to elevated calcium levels by enhancing bone resorption, increasing renal tubular reabsorption, and stimulating active vitamin D production, which boosts intestinal calcium absorption.

• Secondary mechanism: Malignancies can cause hypercalcemia through the secretion of parathyroid hormone-related peptide (PTHrP), mimicking PTH effects, or by direct osteolytic activity, which releases calcium from bones.

• Key complication: Sustained hypercalcemia can result in nephrocalcinosis, leading to renal impairment, and neurological symptoms like confusion or lethargy due to altered neuronal activity.

Section 1

As the clinical team proceeds with the initial assessment, they note that the patient appears visibly fatigued, with a somewhat pale complexion. On further examination, her abdominal pain is localized to the left upper quadrant, and she reports that it worsens after meals. Neurological assessment reveals that her confusion has progressed slightly; she has difficulty recalling recent events and requires more time to respond to simple questions. Muscle strength testing shows generalized weakness, particularly in the proximal muscles.

Laboratory results return, revealing a serum calcium level of 12.5 mg/dL, indicating significant hypercalcemia. Her serum PTH is elevated at 150 pg/mL, reinforcing the suspected diagnosis of primary hyperparathyroidism. In addition, her creatinine level has increased to 1.8 mg/dL, highlighting a decline in renal function, likely exacerbated by nephrocalcinosis. An abdominal ultrasound is ordered, which shows bilateral kidney stones, further complicating her chronic kidney disease.

Based on these findings, the team initiates treatment with intravenous fluids to promote renal excretion of calcium and administers a dose of calcitonin to temporarily reduce calcium levels. Despite these interventions, the patient's neurological symptoms persist, and her mental status remains altered. This prompts consideration of more aggressive interventions, such as bisphosphonates or potential surgical evaluation for parathyroidectomy. The unfolding scenario underscores the need for careful monitoring and re-evaluation, as the team must now prioritize balancing the management of her hypercalcemia while protecting her renal function and addressing her neurological symptoms.

Section 2

As the clinical team continues to monitor the patient, they observe a change in her overall status. Over the next 24 hours, despite the ongoing administration of intravenous fluids and calcitonin, her serum calcium levels remain elevated at 12.2 mg/dL. Her neurological symptoms show little improvement, with persistent confusion and memory deficits. She now exhibits lethargy, prompting further concern. The patient’s vital signs reveal a blood pressure of 150/90 mmHg and a heart rate of 105 beats per minute, indicating mild hypertension and tachycardia, possibly secondary to her electrolyte imbalance and dehydration.

Recognizing the need for more aggressive intervention to address her refractory hypercalcemia and prevent further complications, the medical team decides to initiate treatment with intravenous bisphosphonates, specifically zoledronic acid. This decision is carefully weighed against the risk of worsening her renal function. The team also consults endocrinology and nephrology to assess the feasibility of surgical intervention for her parathyroid condition and to optimize her renal management.

In the meantime, her abdominal symptoms persist, with continued left upper quadrant pain and episodes of nausea, suggesting possible pancreatitis due to hypercalcemia. Serum amylase and lipase levels are ordered, revealing elevated lipase at 250 U/L, supporting the diagnosis. This new complication necessitates a careful reassessment of her treatment plan, emphasizing the need to address both the acute pancreatitis and her persistent hypercalcemia. The team discusses placing the patient on a low-calcium diet and considers the gradual introduction of loop diuretics to enhance renal calcium excretion once her volume status is stable. The patient’s case illustrates the complex interplay between her endocrine, renal, and gastrointestinal systems and underscores the importance of an integrated, multidisciplinary approach to her care.

Section 3

In the subsequent 48 hours, the clinical team observes a change in the patient’s status, indicating a mixed response to the initiated interventions. Her serum calcium levels have decreased slightly to 11.5 mg/dL following the administration of zoledronic acid, yet they remain above normal. Her neurological symptoms persist, albeit with slight improvements in confusion, but her lethargy is more pronounced. This ongoing lethargy raises concerns about potential worsening renal function, prompting the team to order a comprehensive metabolic panel and renal ultrasound for further evaluation.

The metabolic panel reveals a rise in serum creatinine to 1.8 mg/dL from a baseline of 1.2 mg/dL, suggestive of acute kidney injury, likely exacerbated by the bisphosphonate therapy and underlying dehydration. The renal ultrasound shows no evidence of obstruction, indicating that the renal impairment might be functional rather than structural. The team decides to continue cautious rehydration efforts and closely monitor her renal function, balancing the need for diuresis to manage her hypercalcemia with the risk of further renal compromise.

Meanwhile, her abdominal symptoms show minimal improvement, with continued left upper quadrant pain and nausea. Her vital signs now include a blood pressure of 148/88 mmHg and a heart rate of 110 beats per minute, reflecting ongoing mild hypertension and tachycardia. Given the diagnosis of acute pancreatitis, the team emphasizes supportive care, including bowel rest and electrolyte correction. They also consider the potential role of hyperparathyroidism in her refractory hypercalcemia and consult with the surgical team to evaluate the timing and risks of a potential parathyroidectomy, weighing this intervention against her current clinical instability. This integrated approach aims to stabilize her condition while planning for long-term management of her underlying endocrine disorder.

Section 4

In the following 24 hours, the patient's condition shows signs of further complexity. Her serum calcium remains elevated at 11.2 mg/dL despite continuous intervention, and her lethargy has deepened, necessitating more frequent monitoring. Her blood pressure rises to 152/90 mmHg, and her heart rate shows no significant improvement, staying at 108 beats per minute. Neurologically, she demonstrates increased irritability and restlessness, suggesting possible electrolyte imbalances or worsening of her renal function. The clinical team orders a repeat comprehensive metabolic panel, which reveals worsening renal function with a serum creatinine climbing to 2.1 mg/dL. Additionally, there is a mild drop in serum potassium to 3.2 mEq/L, which could be contributing to her tachycardia and muscular irritability.

The worsening renal function prompts the team to reassess the fluid management plan. They decide to reduce the rate of IV fluids to prevent fluid overload while cautiously optimizing electrolyte replacement. Concurrently, they initiate a low-dose loop diuretic therapy to promote calcium excretion without exacerbating her renal condition. Given the potential link between her persistent hypercalcemia and suspected hyperparathyroidism, the endocrine team advocates for an expedited workup, including a serum parathyroid hormone (PTH) assay and a sestamibi scan to assess parathyroid gland activity.

As the team balances these interventions, they remain vigilant for new complications. The patient's abdominal pain persists, prompting reconsideration of her analgesic regimen to avoid nephrotoxic agents. Her overall clinical picture suggests an intricate interplay between her endocrine disorder and renal impairment, highlighting the need for coordinated multidisciplinary care. The team prepares to discuss the potential for surgical intervention with the patient and her family, emphasizing the importance of addressing her underlying condition to prevent further deterioration. The next steps in her management will focus on stabilizing her acute symptoms while planning for definitive treatment of her hyperparathyroidism.

Section 5

Response to Interventions:

Following the initiation of the revised management plan, the clinical team observes a mixed response in the patient's condition. Over the next 12 hours, her serum calcium level shows a slight decrease to 10.8 mg/dL, indicating a modest response to the loop diuretic therapy. However, her renal function continues to present challenges, with serum creatinine peaking at 2.4 mg/dL, suggesting persistent renal compromise. Despite this, her blood pressure stabilizes somewhat, reading at 148/86 mmHg, although her heart rate remains elevated at 106 beats per minute. The patient's irritability reduces slightly, but she continues to exhibit episodes of restlessness, possibly linked to her ongoing electrolyte imbalance.

The repeat metabolic panel reveals a further drop in serum potassium to 3.0 mEq/L, necessitating cautious potassium supplementation to avoid exacerbating her cardiac symptoms. The nursing team is instructed to monitor her cardiac rhythm closely, given the risk of arrhythmias in the context of hypokalemia and hypercalcemia. Additionally, the patient's abdominal pain remains a concern, prompting a switch to a non-nephrotoxic analgesic, which provides some relief and improves her comfort level.

As the team reviews her overall progress, they note the importance of addressing the underlying cause of her hypercalcemia. The endocrine consult has expedited the parathyroid workup, with preliminary results indicating elevated PTH levels, reinforcing the suspicion of primary hyperparathyroidism. The team discusses with the patient and her family the option of surgical intervention, which may offer the best chance for a long-term resolution of her symptoms. Meanwhile, they continue to manage her acute symptoms, with an emphasis on careful monitoring and adjustment of her fluid and electrolyte balance to prevent further complications.
