A client is experiencing decorticate posturing. Which assessment finding would the nurse expect to observe in this client?
Flexion and internal rotation of upper extremities
Flexion and external rotation of upper extremities
Extension and internal rotation of upper extremities
Extension and external rotation of upper extremities
The Correct Answer is A
A. This description accurately depicts decorticate posturing. The characteristic feature of decorticate posturing is the flexion of the upper extremities (arms) and the extension of the lower extremities (legs). The internal rotation of the legs is often observed in this posture. This pattern is seen in severe brain damage, particularly involving the corticospinal tract.
B. External rotation of the arms is not characteristic of decorticate posturing. In decorticate posturing, the arms are flexed and positioned close to the body, with internal rotation being more typical. Therefore, this option does not accurately describe decorticate posturing.
C. Extension of the arms is more characteristic of decerebrate posturing rather than decorticate posturing. Decerebrate posturing involves the extension of both the arms and legs. Internal rotation of the arms is not a typical feature of decerebrate posturing, so this choice does not describe decorticate posturing.
D. Extension and external rotation of the arms describe decerebrate posturing rather than decorticate posturing. Decerebrate posturing is characterized by the extension of the arms and legs, not flexion. Therefore, this option does not describe decorticate posturing.

Correct Answer is B
Explanation
A. Cryoprecipitates are primarily used to treat bleeding disorders and conditions such as hemophilia or fibrinogen deficiencies. They are not the first-line treatment for hypovolemic shock, which is generally due to significant blood or fluid loss rather than clotting deficiencies.
B. Packed RBCs are a critical component in the management of hypovolemic shock, especially when the shock is due to significant blood loss. Administering packed RBCs helps restore the blood volume and improve oxygen delivery to tissues. This is particularly important in cases where the patient has lost a large volume of blood due to trauma, surgery, or other causes.
C. Albumin is used to treat hypovolemic shock when there is a need to increase intravascular volume due to fluid loss that results in low oncotic pressure. It is particularly useful in cases of burns, liver disease, or other conditions where fluid leaks into the interstitial space. While it can be used to manage hypovolemic shock, packed RBCs are typically the primary choice for blood loss.
D. Platelets are used to treat bleeding disorders where there is a deficiency in platelet count or function, such as in thrombocytopenia or during chemotherapy. They are not typically used for hypovolemic shock unless the shock is complicated by severe bleeding and platelet dysfunction.
