A nurse is instructing a client’s family members about feeding safety for a client who has dysphagia following a stroke. Which of the following instructions should the nurse include?

Choice A reason: Justice. This answer is incorrect because justice is the ethical principle that ensures fair and equal treatment for all clients, regardless of their personal or social characteristics. Justice does not apply to this situation, as the client is not being discriminated against or denied any resources.

Choice B reason: Veracity. This answer is incorrect because veracity is the ethical principle that requires honesty and truthfulness from the provider and the nurse in providing information and education to the client. Veracity does not apply to this situation, as the client is not being deceived or misled about their condition or treatment options.

Choice C reason: Fidelity. This answer is incorrect because fidelity is the ethical principle that obligates the provider and the nurse to be faithful and loyal to the client and to honor their commitments and promises. Fidelity does not apply to this situation, as the client is not being abandoned or betrayed by the provider or the nurse.

Choice D reason: Autonomy. This answer is correct because autonomy is the ethical principle that respects the client's right to make their own decisions about their health care, even if they are different from the provider's or the nurse's recommendations. Autonomy applies to this situation, as the client is expressing their preference to discontinue the ventilator, which is a life sustaining treatment.

Choice A reason: Eliciting the gag reflex is not a valid way to assess cranial nerve III. The gag reflex is a protective mechanism that prevents choking or aspiration by triggering a contraction of the pharyngeal muscles when the back of the throat is stimulated. The gag reflex is mediated by cranial nerves IX and X, not III.

Choice B reason: Checking the pupillary response to light is a reliable way to assess cranial nerve III. The pupillary response to light is a reflex that causes the pupil to constrict when exposed to bright light and dilate when exposed to dim light. This reflex helps to regulate the amount of light that enters the eye and protects the retina from damage. The pupillary response to light is controlled by cranial nerve III, which innervates the sphincter pupillae muscle that constricts the pupil.

Choice C reason: Observing for facial symmetry is not a relevant way to assess cranial nerve III. Facial symmetry is the degree of similarity between the two halves of the face. Facial symmetry can be affected by various factors, such as genetics, aging, or facial nerve palsy. Facial nerve palsy is a condition that causes weakness or paralysis of the muscles that control facial expression. Facial nerve palsy is caused by damage to cranial nerve VII, not III.

Choice D reason: Testing visual acuity is not a sufficient way to assess cranial nerve III. Visual acuity is the ability to see fine details and distinguish objects at a distance. Visual acuity depends on various factors, such as the clarity of the lens and cornea, the shape of the eyeball, and the function of the retina. Visual acuity is mainly affected by cranial nerve II, which carries visual information from the retina to the brain. Cranial nerve III does not directly influence visual acuity, but it does innervate some of the muscles that move the eye and enable binocular vision.
