A nurse is performing a cranial nerve assessment on a client following a head injury. Which of the following findings should the nurse expect if the client has impaired function of the vestibulocochlear nerve (cranial nerve VIII)?

Choice A reason:

Palpating the dorsalis pedis pulse is the appropriate option. Checking the dorsalis pedis pulse is crucial to assess the perfusion and circulation to the affected extremity. This is an important nursing action to monitor the patient's vascular status and ensure that there is adequate blood flow to the extremity distal to the fixator. A decrease or absence of the dorsalis pedis pulse could indicate potential circulation issues and require immediate attention.

Choice B reason:

Adjusting the clamps on the fixator frame is incorrect. The nurse should not adjust the clamps without specific orders from the healthcare provider. The external fixator is typically secured according to the surgeon's specifications, and any adjustments should be made under the guidance of the surgical team.

Choice C reason:

Wrapping sterile gauze on the sharp point of the pins is incorrect. The sharp pins used in an external fixator are an integral part of the device and are placed to stabilize the fracture. They should not be covered with sterile gauze, as this could interfere with their function and increase the risk of infection.

Choice D reason:

Maintaining the affected extremity in a dependent position is incorrect. Keeping the affected extremity in a dependent position (lower than the heart) can increase swelling and impair circulation. After surgery and fixation, it's often recommended to elevate the extremity to reduce swelling and promote proper circulation.

Choice A Reason:

Administering the unit of packed RBCs over 1 hour is not appropriate. Packed RBCs are usually administered over a longer period of time (typically 2 to 4 hours), as rapid infusion can lead to adverse reactions. The rate of administration should be based on institutional policy.

Choice B Reason:

Initiating venous access with a 21-gauge needle is not appropriate-. The needle size for venous access can vary based on the client's condition and the size of their veins. However, a larger gauge needle (e.g., 18-gauge or 20-gauge) is typically used for blood transfusions to ensure adequate flow.

Choice C Reason:

Blood products should be infused through administration sets designed specifcally for blood; use a Y-tubing or straight-tubing blood administration set that contains a filter designed to trap fibrin clots and other debris that accumulate during blood storage.

Choice D Reason:

The nurse should measure vital signs and assess lung sounds before the transfusion and again after the first 15 minutes and every 30 minutes to 1 hour (per agency policy) until 1 hour after the transfusion is completed.
