A nurse is preparing to assess a client. Which action should the nurse take to check cranial nerve VI?
Open the client’s visual acuity using a Snellen chart.
Whisper none of the client’s ears while blocking the other.
Ask the client to inspect up.
Ask the client to smile.
The Correct Answer is C
Choice A Reason:
Open the client’s visual acuity using a Snellen chart is incorrect. This action assesses cranial nerve II (optic nerve), which is responsible for vision. The Snellen chart is used to measure visual acuity, not the function of cranial nerve VI
Choice B Reason:
Whisper none of the client’s ears while blocking the other is incorrect. This action assesses cranial nerve VIII (vestibulocochlear nerve), which is responsible for hearing and balance. Whispering tests the auditory function of this nerve.
Choice C Reason:
Ask the client to inspect up is correct. Cranial nerve VI (abducens nerve) controls the lateral rectus muscle, which is responsible for moving the eye outward. Asking the client to look up and outward helps assess the function of this nerve.
Choice D Reason:
Ask the client to smile is incorrect. This action assesses cranial nerve VII (facial nerve), which controls the muscles of facial expression. Smiling tests the motor function of this nerve.

Correct Answer is D
Explanation
Choice A Reason:
“Call the provider” is important but not the first priority. The immediate concern is to maintain the client’s intravenous access to ensure they can receive any necessary medications or fluids promptly. Once the line is secured, the provider should be notified to receive further instructions and manage the client’s condition.
Choice B Reason:
“Notify the blood bank” is also crucial but comes after ensuring the client’s immediate safety. The blood bank needs to be informed to investigate the cause of the reaction and prevent further issues, but this step follows the initial emergency interventions.
Choice C Reason:
“Collect a urine specimen” is necessary to check for hemolysis, which can occur during a transfusion reaction. However, this is not the first step. The priority is to stabilize the client by maintaining IV access with normal saline.
Choice D Reason:
“Keep the line open with 0.9% NS through new tubing” is the correct first intervention. This action ensures that the client remains hydrated and that the IV line is available for any emergency medications or treatments. Using new tubing prevents any contamination from the transfusion set.
Correct Answer is D
Explanation
Choice A Reason:
“Delivers a low concentration of oxygen” is incorrect because a nasal cannula can deliver varying concentrations of oxygen depending on the flow rate set by the healthcare provider. The concentration can range from low to moderate, typically between 24% to 44%.
Choice B Reason:
“Delivers a constant rate of oxygen” is partially correct but not entirely accurate. While the flow rate can be constant, the key aspect is the specific concentration of oxygen delivered, which is more relevant to the client’s understanding.
Choice C Reason:
“Delivers a high concentration of oxygen” is incorrect because nasal cannulas are generally used for low to moderate oxygen delivery. High concentrations of oxygen are typically delivered through other devices like non-rebreather masks or high-flow nasal cannulas.
Choice D Reason:
“Delivers a constant flow of a specific concentration of oxygen” is correct. This explanation accurately describes how a nasal cannula works. It provides a continuous flow of oxygen at a specific concentration, which is adjusted based on the client’s needs and the healthcare provider’s prescription.
