Final answer:
Following a primary assessment, conduct a detailed neurological and sensory examination before further imaging, such as a CT scan. Signs of sensory deficits cue further investigation, and aspirin therapy may be initiated to prevent clot formation pending a thorough evaluation.
Step-by-step explanation:
After completing the scene size-up and primary assessment of a 76-year-old male who fell from a standing position, you should perform a detailed secondary assessment. This would involve checking the patient's neurological function, such as asking them to smile, raise their eyebrows, stick out their tongue, and shrug their shoulders to assess cranial nerve integrity. You should also test muscular strength by providing resistance while the patient attempts to lift his arms and legs. Furthermore, a sensory examination would be appropriate, whereby with his eyes closed, the patient indicates when he feels the tip of a pen touch various parts of his body.
If the patient exhibits signs like feeling pins and needles in his left arm and leg, or difficulty sensing touch, further examination should be done before a CT scan. The presence of these symptoms suggests a possible disruption in the sensory systems between the spinal cord and brain. As a preventative measure, and without contraindications noted, the patient may be put on aspirin therapy to reduce the risk of blood clot formation which could exacerbate neurological deficits if an embolism is suspected.
