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
The correct answer is d) Tighten the abdominal muscles while exhaling.
Choice A Reason:
“Raise both shoulders while breathing deeply” is incorrect. Diaphragmatic breathing focuses on using the diaphragm rather than the shoulders. Raising the shoulders can lead to shallow chest breathing, which is less effective for oxygen exchange.
Choice B Reason:
“Inhale through the mouth” is incorrect. For diaphragmatic breathing, it is recommended to inhale through the nose. This helps filter, warm, and humidify the air before it reaches the lungs.
Choice C Reason:
“Exhale through the nose” is incorrect. While exhaling through the nose is beneficial in some breathing exercises, diaphragmatic breathing typically involves exhaling through pursed lips. This technique helps slow down the exhalation and keeps the airways open longer.
Choice D Reason:
“Tighten the abdominal muscles while exhaling” is correct. Tightening the abdominal muscles helps push the diaphragm up, forcing air out of the lungs more efficiently. This action is a key component of effective diaphragmatic breathing.
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.
