hip fracture - Nursing Case Study
Pathophysiology
• Primary mechanism: Osteoporosis leads to decreased bone mineral density, making bones fragile and more susceptible to fractures, particularly in the hip, which bears significant weight and stress.
• Secondary mechanism: Falls, often due to impaired balance or environmental hazards, are a common trigger for hip fractures in individuals with weakened bone structure.
• Key complication: A hip fracture can result in impaired mobility, potentially leading to complications such as deep vein thrombosis or pulmonary embolism due to prolonged immobility.

Section 1
As the nursing team begins the initial assessment, they note that the patient, Mrs. Thompson, is exhibiting signs of acute confusion, which may be indicative of delirium. This is concerning considering her recent fall and the possibility of a hip fracture. The team performs a focused neurological assessment to evaluate her mental status further, acknowledging that her confusion and restlessness could stem from multiple factors, including pain, infection, or even a reaction to the trauma. Her Glasgow Coma Scale score is slightly reduced at 13, with disorientation to time and place.
The physical assessment reveals significant swelling and ecchymosis around the right hip area. The leg appears shortened and externally rotated, classic signs suggestive of a hip fracture. Given her osteoporosis, these findings align with the suspicion of a femoral neck fracture. The nursing team prioritizes pain management, administering acetaminophen as she has no known allergies to it, while cautiously avoiding opioids due to her confusion.
Laboratory tests are ordered, including a complete blood count (CBC) and basic metabolic panel, to rule out any underlying infection or electrolyte imbalance contributing to her altered mental state. An elevated white blood cell count of 15,000/mm³ with a left shift is noted, raising the suspicion of an infectious process, possibly pneumonia, given her elevated temperature and respiratory rate. These findings necessitate further investigation and intervention to prevent complications such as sepsis. The team prepares Mrs. Thompson for imaging studies, including an X-ray of the hip, to confirm the fracture diagnosis, while also considering a chest X-ray to assess for any pulmonary involvement. This comprehensive approach allows for a timely identification of both orthopedic and potential infectious complications, setting the stage for the next steps in her care journey.
Section 2
The imaging studies confirm the presence of a displaced femoral neck fracture on the right side, necessitating an urgent orthopedic consultation to discuss surgical intervention. Concurrently, the chest X-ray reveals a mild infiltrate in the right lower lobe, consistent with aspiration pneumonia, which could explain the elevated white blood cell count and respiratory symptoms. Mrs. Thompson's vital signs show a persistent low-grade fever of 100.8°F, a respiratory rate of 24 breaths per minute, and a heart rate of 104 beats per minute, suggesting her body is mounting a response to the infection.
In light of these findings, the nursing team collaborates with the medical team to initiate a broad-spectrum antibiotic regimen, taking into account her renal function and potential drug interactions. They also implement supportive measures such as supplemental oxygen to maintain her oxygen saturation above 92% and encourage deep breathing exercises to prevent further pulmonary complications. The interdisciplinary team emphasizes the importance of monitoring her fluid and electrolyte status closely, given her increased insensible losses due to fever and increased respiratory effort.
As Mrs. Thompson stabilizes, her confusion begins to resolve slightly, indicating that addressing the infectious component is contributing positively to her cognitive state. However, the team remains vigilant for any signs of deterioration, such as worsening respiratory status or hemodynamic instability, which could signify progression to sepsis. Plans are made to optimize her condition for potential surgical repair of the hip fracture, balancing the need for prompt orthopedic intervention with the imperative to manage her pneumonia effectively. This dual focus ensures that both immediate and long-term outcomes are prioritized, setting the stage for ongoing assessment and adaptation of her care plan.
Section 3
As the interdisciplinary team continues to manage Mrs. Thompson's condition, a new set of laboratory results returns, providing further insight into her current status. The complete blood count reveals a white blood cell count that remains elevated at 14,500/mm³, indicating ongoing infection, but with a slight downward trend suggesting a modest response to the antibiotic therapy. Her blood urea nitrogen and creatinine levels are stable, reflecting adequate renal function despite the infection and increased insensible losses. Electrolyte analysis shows a mild hyponatremia with a serum sodium level of 132 mEq/L, which prompts the team to review her fluid management strategy, carefully balancing the need for hydration with the risk of fluid overload given her respiratory status.
In addition to the lab results, a follow-up chest X-ray is ordered to assess the progression of the pneumonia. The imaging reveals that the infiltrate in the right lower lobe has not significantly worsened, and there is no evidence of pleural effusion, which is reassuring in the context of her current treatment plan. However, the respiratory team notes subtle signs of atelectasis, likely due to her limited mobility and shallow breathing, emphasizing the importance of continued incentive spirometry use and regular repositioning to enhance lung expansion.
With these findings, the care team conducts a thorough reassessment of Mrs. Thompson. Her vital signs show a slight improvement in her respiratory rate, now at 22 breaths per minute, and her heart rate has decreased to 98 beats per minute, suggesting partial resolution of her systemic inflammatory response. Despite these improvements, her oxygen saturation intermittently drops to 90% on room air, necessitating ongoing supplemental oxygen. The team continues to monitor her closely for any signs of clinical deterioration, as they prepare to transition her towards surgical intervention for her hip fracture once her pneumonia is more controlled. This delicate balancing act between managing her acute infection and preparing for orthopedic repair remains the central focus of her care trajectory.
Section 4
As Mrs. Thompson's care progresses, the interdisciplinary team notes a change in her status that warrants immediate attention. During a routine assessment, the nurse observes that Mrs. Thompson is increasingly lethargic and more difficult to rouse than in previous assessments. Her Glasgow Coma Scale score has decreased to 13 from a baseline of 15, indicating a new neurological concern. Concurrently, her blood pressure has dropped to 100/60 mmHg, and the previous improvement in her heart rate has reversed, now spiking to 110 beats per minute. Her oxygen saturation continues to fluctuate, intermittently dipping to 88% even with supplemental oxygen, indicating a potential worsening of her respiratory status.
In light of these changes, the team orders a series of additional diagnostics to identify the underlying cause. A repeat complete blood count shows a further decrease in hemoglobin to 10.5 g/dL, suggesting possible bleeding or inadequate erythropoietic response. Given the recent surgical history and ongoing infection, there is concern for potential sepsis or evolving anemia. Blood cultures are drawn to rule out bacteremia, and an arterial blood gas is ordered, revealing a pH of 7.32 with a bicarbonate level of 18 mEq/L, consistent with metabolic acidosis. These findings prompt the team to initiate a sepsis protocol, including broad-spectrum antibiotics while awaiting culture results, and to assess the need for a possible blood transfusion.
This shift in Mrs. Thompson's condition underscores the complexity of her care and highlights the need for vigilant monitoring and prompt intervention. The team discusses the challenges of balancing her fluid status to address both the hyponatremia and the risk of fluid overload. They also consider the potential need for mechanical ventilation support if her respiratory status continues to decline. As the team navigates these developments, they remain focused on stabilizing Mrs. Thompson to ensure she is fit for eventual surgical repair of her hip fracture, recognizing that her recovery trajectory is intricately linked to the resolution of these acute complications.
Section 5
As the team implements the sepsis protocol, Mrs. Thompson's condition is closely monitored for any response to the interventions. Within a few hours, her vital signs show a subtle yet crucial shift. Her heart rate stabilizes slightly at 100 beats per minute, and her blood pressure remains steady, although still low, at 105/65 mmHg. Despite these efforts, her oxygen saturation remains unstable, occasionally dropping to 86%, indicating a persistent respiratory challenge. The team decides to administer a blood transfusion, given her hemoglobin level of 10.5 g/dL and signs of anemia, to improve oxygen delivery and support her hemodynamic status.
The interdisciplinary team reconvenes to reassess her fluid management plan, given the delicate balance required to address both the risk of fluid overload and her ongoing hyponatremia. Her electrolyte panel reveals a sodium level of 130 mEq/L, suggesting mild improvement, but vigilance is necessary to prevent further complications. Additionally, her repeat arterial blood gas shows a slight improvement in metabolic acidosis, with a pH of 7.35 and a bicarbonate level of 20 mEq/L, indicating a positive initial response to the interventions.
Despite these developments, new complications arise when Mrs. Thompson exhibits increased work of breathing and diminished breath sounds on auscultation, raising concerns about the potential onset of acute respiratory distress syndrome (ARDS). The team discusses the potential need for mechanical ventilation support, weighing the risks and benefits given her fragile state. This decision is pivotal as they aim to stabilize her respiratory function while continuing to address the underlying sepsis and prepare her for the eventual surgical repair of her hip fracture. The team remains vigilant, ready to adapt their plan as Mrs. Thompson's condition evolves, ensuring they remain one step ahead in her complex care journey.
