6. Injury to which nerves causes wrist drop and foot drop?
- radial and peroneal nerve respectively
7. What is the normal ratio between the blood pressure at the ankle divided by that of an uninjured arm?

- Shoulder abduction, axillary nerve
18. When testing motor function, what motion tests for C6? what is the associated nerve?
- Elbow flexion (C5 and C6), musculocutaneous nerve
19. Which brachial nerves are tested by assessing a patient's ability to extend their elbow?
- Radial nerve, C6, C7, C8
20. Which nerves are assessed when testing a patient's grip strength?
- Dorsiflexion of the wrist => radial nerve, C6
Flexion of the fingers => median and ulnar nerves, C7, C8

- Plantar flexion
24. What is the earliest symptom/sign of compartment ischemia?
- pain, especially on passive stretch of involved muscle of the injured extremity.
25. What is a late sign of inhalation burn injury?
- Stridor => indication for immediate endotracheal intubation
26. Patients with greater than what % of TBSA burn require fluid resuscitation?
- >20%
27. What is the preferred solution for resuscitation of burn victims?
- Lactated ringers.
28. Why do first degree burns not require IV fluid replacement?
- Because the epidermis is not compromised in this type of burn
29. What characterizes a partial thickness burn?
- red or mottled appearance of the skin associated with swelling and blister formation. Can have a weeping, wet appearance and painfully hypersensitive.
30. What characterizes a full-thickness burn? How will the surface look? dry or wet? redness? degree of swelling?
- Appear dark and leathery, or skin can appear translucent or waxy white.
Surface is usually PAINLESS and generally dry though may be red but does NOT blanch white with pressure. There is little swelling, though surrounding tissue may have significant amount. [Show Less]
