Early recognition and treatment are crucial to the reversibility and extent of the symptoms. The goal of this paper is to present a subjective, objective, assessment, and plan (SOAP) for an older patient with presenting neurologic symptoms. The paper also aims to present the differential diagnoses for this case and their associated treatments and teachings. The paper will reflect on the learnings encountered while reviewing the case study. SOAP Note Subjective Patient Information: Mr. Mario, 66-year-old, Male, Hispanic Chief Complaint: Mr. M was brought in to the emergency department by the advance squad team with reports of acute aphasia, right facial droop, and right sided weakness. History of Present Illness: Mr. M is a 66-year-old Hispanic male who was brought in by fire rescue for acute aphasia, right facial droop, and right sided weakness. The sudden onset of symptoms occurred at work at the post office where one of his co-workers notified 911. The ambulance noted neurologic symptoms that alerted the emergency department for a possible stroke alert.

The characteristics mentioned were all pertinent negatives for the patient in the case study. Mario is an older male with a history of hypertension and diabetes. For these reasons, this diagnosis can be ruled out. Patient has no known psychiatric or psychologic history to associate this diagnosis with and no stressor has been stated to contribute to this diagnosis for Mario. Plan Laboratory/Diagnostic Tests: 1. Computed Tomography (CT) Scan of the Brain- Patient within the time window for intravenous thrombolytic are recommended by guidelines to have a non-contrast CT scan or MRI to exclude cerebral hemorrhage or evaluate ischemic changes. Non-contrast CT scan is the first line imaging tool in suspected stroke and recommended as an initial mode of imaging to determine decisions for IV alteplase. Ischemic changes in the anterior aspect of the brain can be identified in the scan using the Alberta Stroke Program Early CT Score, a simple 10-point CT score dividing the mid-cerebral artery territory into 10 regions (Lin & Liebeskind, 2016). By identifying that there is no hemorrhage in the CT scan, providers will rule in that an ischemic stroke is positive if symptoms are still persistent; hence, it identifies if the patient is a candidate for thrombolysis. However, this test has a specificity of 56% to 100% and poor sensitivity of 20 to 75% for detecting ischemic changes in the early stage (six to eight hour window), especially for posterior strokes (Lin & Liebeskind, 2016). A diffusion weighted imaging (DWI) is a better 11 imaging modality for early ischemic stroke. The onset of Mario’s symptoms was not specified, but the case reported that a co-worker identified the symptoms at work and called 911 immediately. If onset of symptoms were less than six hours, the ischemic stroke is in its early stage; hence, the CT result performed did not identify it but confirmed that it was negative for a hemorrhage. If a posterior stroke is suspected, then a DWI would be a better option for the provider. 2. Magnetic Resonance Imaging (MRI) –Patients with symptoms presenting as acute vestibular syndrome or suspected posterior infarction is recommended to undergo acute DWI MRI (Yew & Cheng, 2015). The said imaging modality has a sensitivity of 91% to 100% and specificity of 86% to 100% (Lin & Liebeskind, 2016). However, MRI may miss posterior strokes in the first 48 hours; hence, a repeat MRI in three to seven days should follow a negative initial MRI result to exclude a false negative result (Yew & Cheng, 2015). MRI shows greater sensitivity for small volume ischemia or when there is no time pressure to offer treatment; therefore, it is used as a follow-up imaging. 3. CT Angiography – The imaging will identify occluded intracranial vessel and evaluate extracranial carotid, extracranial vertebral, aortic arch and proximal great vessels in managing major ischemic stroke, if not immediately, then over the next several days (Musaka et al., 2015). 4. Carotid Duplex- This is a type of ultrasound to check if the cause is due to carotid artery stenosis, which is narrowing of the major blood vessels that supplies blood to the brain. 5. PT/INR and aPTT – Coagulation studies is important during a stroke. The American Heart and Stroke Association released the 2018 guidelines for the early management of patients with acute ischemic stroke. The guideline stated that patients with clearly no 12 current use of warfarin, non-vitamin K antagonist, or heparin may have intravenous thrombolysis started prior to the said lab results, but needs to be stopped when INR is over 1.7 (Lokeskrawee et al., 2019). 6. EKG – Electrocardiogram will be ordered to detect any underlying heart disorder. According to Chaturvedi (2017), atrial fibrillation is the leading cause of cardioembolic stroke, and is paroxysmal in a significant proportion of patients. In addition, EKG can detect other relevant cardiac issues including myocardial ischemia and ventricular arrhythmias. 7. NIH Stroke Scale – The scoring scale is developed to help clinicians to objectively rate the severity of the ischemic stroke. Higher scores indicate a severe score and usually correlates with the size of the blockage in the artery in the CT scan and MRI Treatment 1. Keep patient nothing by mouth – Stroke patients are at risk for aspiration due to central or local weakness or incoordination of the muscles in the pharynx or impaired gag reflex 2. Oxygen Nasal cannula for oxygen saturation below 94%. 3. Administer Alteplase (onset is less than 4.5 hours) – Intravenous administration of recombinant tissue plasminogen activator (alteplase) has shown to lower functional disability, with an absolute risk reduction of 7%-13%nas compared to placebo; hence, has become the major specific treatment recommended in the management of an acute ischemic stroke (Musuka et al., 2015). Efficacy wanes quickly and associated risks like bleeding increases with time elapsed from symptom onset; therefore, early diagnosis and treatment is required. Patients with disabling acute ischemic changes are candidates for 15 Teaching the family on the causes of stroke is crucial, so they can control the individual risk factors and prevent future events. In Mario’s case, four risk factors for having a stroke include his history of diabetes, cigarette smoking, history of heart diseases (hypertension), and his body weight or obesity. The four risk factors are emphasized because they are modifiable risk factors. Mario is a newly diagnosed diabetic. Diabetes is an independent risk factor for stroke. Literature shows that risk doubles in stroke for diabetic patients and that 20% of deaths in diabetics is due to stroke (Boehme et al., 2017). According to Boehme et al. (2017), cigarette smoking is a major risk factor for stroke, doubling the risk with a dose response relationship between the number of pack years and risk for stroke. Mario was reported to smoke to a pack and a half daily. Meanwhile, hypertension is the most modifiable risk factor for stroke. Hypertension has a significant, direct and continuous relationship with stroke risk (Boehme et al., 2017). Mario has been reported to be non-compliant with his medications for his blood pressure. Uncontrolled hypertension puts him at a very high risk for a stroke. Lastly, on obesity, it was noted that Mario has a BMI of 42.1, which is considered as obesity. A recent large meta- analysis showed that 76% of the effect of the BMI on stroke risk was mediated by elevated blood pressure, cholesterol, and glucose levels (Boehme et al., 2017). 4. Home exercise programs to maintain optimal functional levels will be encouraged. Tailored exercise programs with balance training components will reduce falls, enhance cardiorespiratory fitness and improve cognition and memory (Kennedy-Malone et al., 2019). Periodic follow up with the primary provider to monitor recovery, complications, manage risk factors and secondary prevention. Reflection 16 From the case, it was learned that neuroimaging provides crucial information about the brain and the vessels to enhance rational decisions to start reperfusion therapy. CT scan is the gold standard in identifying an ischemic stroke, but it does not confirm early ischemic stroke. It is also interesting to note that different imaging modalities are available to confirm the specific cause of the ischemic stroke. Imaging protocols are also dependent on available resources, local preference, and preference of the clinician. It is vital that a nurse practitioner has adequate expertise and uses proper clinical context, along with the imaging results to accelerate decision making. Summary Stroke is one of the leading causes of death and disability in the country. Advances in the diagnosis and treatment are now available to help decrease the stroke burden in our society, especially to the older population. Stroke is characterized by the acute onset of neurologic symptoms like acute aphasia, facial droop, and unilateral weakness, which were the presenting symptoms of the patient in the case study. As the first provider to see the patient with acute stroke, their decision can have a profound impact in the outcome of stroke. Follow up care, referral and adequate teaching are significant for the patient’s recovery to ensure that a stroke patient like Mario will have his highest functional abilities restored and maintained. 17 References Boehme, A.
