Susan Onianwa Week 5 Case Study 1. The CT reveals several issues with the cranial structure, one of which might be in the cribriform plate but the image isn't well defined. What non-invasive test can you do to test if the cribriform plate is severely damaged? Why? Usually, when the cribiform plate is damaged, there will be a cerebral spinal fluid leak. A non invasive test could be to test to see if there are beta protein traces and beta-2- transferrin traces in the nasal secretions. A positive response for having these proteins present is a sign of cerebral spinal fluid leak. 2. The doctor tests the patient's field of view with an astigmatism chart and finds that the patient states that there are blind spots and distorted lines in both eyes he never noticed before. These blinds spots and distortions remain constant. What structure within the eye could cause these distortions? How can you verify your suspicion? Cornea imperfections can cause distortions. It could be caused when an artery bursts and blood enters the vitreous humour. In order to verify that this is the cause, the doctor can use a slit lamp to look into the eye for any blood. The doctor can also order an ultrasound of the eye. 3. Both his lungs have received some damage and both tympanic membranes have burst during the explosion. Why? The impact to the body damaged both lungs. Blast injuries are known to cause injury to the lungs and tympanic membranes. Some other injuries such as contusions, pneumothorax, and pulmonary injuries could occur with exposure to grill pressures higher that 40psi. The grill pressure was past the 40PSI guideline.
