Final answer:
An initial systematic assessment may identify abnormalities such as altered sensory perception and muscle weakness, suggesting issues in sensory pathways or possible embolic events, leading to further diagnostic measures and interventions like aspirin therapy.
Step-by-step explanation:
When conducting an initial systematic assessment and encountering findings outside the expected 'normal' range, areas such as altered sensory perception, which is indicated by the patient's report of 'pins and needles' in the left arm and leg, must be highlighted. This finding suggests that there may be a disruption in the sensory pathways from the spinal cord to the brain.
Other considerations for abnormal findings could include muscle weakness if the patient struggles against resistance during muscle strength testing or delays in response to visual cues. The onset of these symptoms, along with difficulty sensing touch, are significant observations that imply a need for further diagnostic tests such as a CT scan. The prescription of aspirin therapy indicates a suspicion of an embolic event, and the aim is to prevent further blood clots. These symptoms and the treatment plan chosen impact the differential diagnosis and guide subsequent medical intervention.
