urinary tract infection - Nursing Case Study

Pathophysiology

• Primary mechanism: Bacterial invasion predominantly by Escherichia coli from the gastrointestinal tract into the urethra, ascending to the bladder. This causes inflammation of the urinary epithelium (cystitis), leading to symptoms such as dysuria and increased frequency of urination.

• Secondary mechanism: Bacterial adherence to the urothelial cells via pili or fimbriae, allowing colonization and evasion of host defenses. This adhesion impairs natural urinary flushing and initiates a strong inflammatory response, recruiting immune cells and causing tissue irritation.

• Key complication: If the infection ascends further to the kidneys, it can lead to pyelonephritis, characterized by fever, flank pain, and potential renal scarring, posing a risk of chronic kidney damage if not promptly and effectively treated.

Section 1

As the patient remains under observation, her condition begins to evolve, presenting new diagnostic results that warrant careful clinical reasoning. A urinalysis reveals significant findings: the presence of leukocyte esterase, positive nitrites, numerous white blood cells, and moderate red blood cells, all indicative of a robust urinary tract infection. A urine culture confirms the presence of Escherichia coli with a high bacterial load, aligning with her history of recurrent UTIs. Blood tests reveal leukocytosis, with a white blood cell count of 13,500/µL, which supports the presence of an active infection. Her renal function appears compromised, as indicated by slightly elevated serum creatinine levels at 1.4 mg/dL, raising concerns about potential kidney involvement.

Given these results, the healthcare team discusses the possibility of pyelonephritis. The patient begins to exhibit signs consistent with this complication: persistent fever, worsening flank pain, and increased tenderness upon palpation of the costovertebral angle. Her blood pressure remains elevated, and her heart rate has increased slightly to 110 bpm, suggesting heightened physiological stress. The decision is made to initiate an intravenous antibiotic regimen targeting gram-negative organisms, given her penicillin allergy, with close monitoring for therapeutic response and potential adverse effects.

These developments highlight the importance of timely intervention and monitoring for complications that might necessitate further escalation of care. The team emphasizes the need for hydration to support renal function and plans for repeat renal function tests to assess her response to treatment. This case illustrates the interconnectedness of clinical findings and the necessity of adapting the care plan to address emerging complications, with the ultimate goal of preventing chronic sequelae.

Section 2

As the patient continues to receive intravenous antibiotics, the healthcare team closely monitors her response to the treatment. Initially, there is a slight improvement in her symptoms; her fever begins to subside, and her flank pain decreases marginally. However, the repeat renal function tests reveal a concerning trend: her serum creatinine has risen to 1.6 mg/dL, indicating worsening renal impairment. Concurrently, her blood urea nitrogen (BUN) level has increased to 28 mg/dL, further suggesting a decline in kidney function. These findings prompt the team to consider the possibility of acute kidney injury (AKI) secondary to the evolving infection and its complications.

Despite the administration of fluids to promote renal perfusion and support, the patient's urinary output remains reduced, with a noticeable decrease over the past 24 hours. Her blood pressure, while initially elevated, has begun to drop, now measuring 100/65 mmHg, raising concerns about potential sepsis and its impact on her hemodynamic stability. The patient also reports new-onset nausea and mild confusion, which could be indicative of uremic symptoms or worsening systemic infection.

Given these developments, the healthcare team recognizes the need to reassess the treatment strategy, considering potential nephrotoxic effects of antibiotics and the risk of sepsis. They deliberate on adjusting her antibiotic regimen, considering alternative options that are less likely to compromise renal function. Additionally, plans are made to escalate supportive care, including more aggressive fluid management and potential renal replacement therapy if her condition does not improve. This stage of the patient's journey emphasizes the critical role of ongoing evaluation, timely recognition of complications, and dynamic adaptation of the care plan to mitigate risks and optimize outcomes.

Section 3

As the healthcare team continues to monitor the patient closely, they note a change in her status that warrants immediate attention. Over the next 12 hours, her blood pressure continues to decline, now measuring 92/58 mmHg. This hypotension, coupled with her ongoing decreased urinary output of less than 400 mL over 24 hours, raises the suspicion of progressing sepsis. Her heart rate has increased to 110 beats per minute, indicating a compensatory response to her dropping blood pressure. The patient's oxygen saturation remains stable at 95% on room air, but her respiratory rate has increased to 24 breaths per minute, suggesting increased respiratory effort and potential metabolic acidosis.

New laboratory results reveal a further elevation in serum creatinine to 2.0 mg/dL and BUN to 34 mg/dL, confirming the progression of acute kidney injury. Additionally, her white blood cell count has spiked to 18,000/mm³, pointing to an exacerbated inflammatory response. Blood cultures are positive for Escherichia coli, confirming the source of the systemic infection. The team considers the implications of these findings, recognizing the need to adjust the treatment plan to address both the infection and the compromised renal function, while also preventing further hemodynamic instability.

In response to these developments, the healthcare team escalates her care by initiating broad-spectrum antibiotics with less nephrotoxic potential and increasing intravenous fluid administration to support her circulatory volume and improve renal perfusion. They also consider the early initiation of renal replacement therapy to manage the rising levels of uremic toxins, given her worsening renal function and the new onset of confusion. The team continues to monitor her hemodynamic status closely, ready to initiate vasopressor support if her blood pressure fails to stabilize. This phase of the patient's journey underscores the importance of dynamic clinical decision-making and the need for interdisciplinary collaboration to navigate the complexities of her evolving condition.

Section 4

As the healthcare team continues to monitor the patient's response to the adjusted treatment plan, they closely observe her clinical status for any signs of improvement or further deterioration. Over the next several hours, despite the administration of intravenous fluids and broad-spectrum antibiotics, the patient's blood pressure remains unstable, now fluctuating between 88/55 mmHg and 94/60 mmHg. Her heart rate persists at an elevated level of 115 beats per minute, and her respiratory rate has increased slightly to 26 breaths per minute, indicating ongoing compensatory mechanisms in response to her hemodynamic instability.

The patient's mental status has shown signs of further decline, with increased confusion and disorientation, raising concerns about cerebral perfusion and the potential onset of septic encephalopathy. New laboratory results reveal a further elevation in lactate levels to 3.5 mmol/L, suggesting worsening tissue hypoperfusion and the likelihood of persistent metabolic acidosis. Although her oxygen saturation remains stable at 94% on room air, the team recognizes the need for heightened vigilance regarding her respiratory status.

In light of these developments, the decision is made to initiate vasopressor support to maintain adequate mean arterial pressure and ensure sufficient organ perfusion. Norepinephrine is started at a low dose and titrated carefully based on her blood pressure response. The team continues to evaluate her renal function closely, noting that her urine output remains critically low, with only 150 mL over the past 12 hours. As the patient's condition evolves, the interdisciplinary team prepares for the potential need for more aggressive interventions, such as mechanical ventilation or continuous renal replacement therapy, should her status fail to improve with current measures. These steps highlight the complexity of managing sepsis with acute kidney injury and the importance of timely, coordinated clinical decisions to optimize patient outcomes.

Section 5

As the clinical team continues to monitor the patient, new diagnostic results provide further insight into her deteriorating condition. A repeat blood culture confirms the presence of Escherichia coli, a common causative agent of urinary tract infections, but now with evidence suggesting antibiotic resistance to the current regimen. This prompts an immediate consultation with the infectious disease specialist, who recommends a switch to a more targeted antibiotic based on the sensitivity profile. In addition to the resistant strain of E. coli, the latest complete blood count reveals a rising white blood cell count of 18,000/mm³, indicative of an escalating systemic inflammatory response.

The patient's renal function tests show a concerning upward trend in her creatinine levels, now at 2.3 mg/dL, reflecting a worsening acute kidney injury. This, coupled with her oliguria, heightens the need for potential renal replacement therapy. Furthermore, a bedside echocardiogram is performed to assess cardiac function, which reveals a slightly reduced ejection fraction of 50%, suggesting that the heart is starting to struggle under the stress of sepsis despite the ongoing vasopressor support.

In response to these diagnostic findings, the team adjusts the patient's treatment plan to incorporate the newly recommended antibiotic and closely monitors her renal function for any further decline. The decision to potentially initiate continuous renal replacement therapy is approached with caution, as the team weighs the risks and benefits of such invasive interventions. The interdisciplinary team remains vigilant, ready to adapt the treatment strategy as more data becomes available, fully aware of the delicate balance required to manage this case of sepsis with associated complications.
