Nursing Elites

1. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?

• A. Assessing visual acuity
• B. Inspecting the eyelids for ptosis
• C. Assessing pupil constriction
• D. Assessing ocular movements

Correct answer: A

Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.

2. The LPN is preparing a client for discharge, and the discharge medications include phenobarbital. Which of these client statements would indicate a need for reinforced teaching about this medication?

• A. "I will need to avoid eating excessive leafy greens."?
• B. "It's best to take this medication with food."?
• C. "I can't wait to get back to my nightly glass of wine."?
• D. "I should try to take this medication at the same time every day."?

Correct answer: C

Rationale: The correct answer is, "I can't wait to get back to my nightly glass of wine,"? as phenobarbital should not be taken with alcohol as it is a barbiturate. Alcohol may increase the sedative effect, posing risks to the patient's safety. Choice A, "I will need to avoid eating excessive leafy greens,"? is unrelated to phenobarbital and not a cause for reinforced teaching. Choice B, "It's best to take this medication with food,"? is a general instruction and not specific to phenobarbital. Choice D, "I should try to take this medication at the same time every day,"? is a common recommendation for medication adherence but does not highlight a specific concern related to phenobarbital.

3. If Ms. Barrett's distance vision is 20/30, which of the following statements is true?

• A. The client can read from 20' what a person with normal vision can read at 30'.
• B. The client can read from 30' what a person with normal vision can read at 20'.
• C. The client can read the entire chart from 30'.
• D. The client can read the chart from 20' with the left eye and from 30' with the right eye.

Correct answer: A

Rationale: When Ms. Barrett's distance vision is measured as 20/30, it means that she can read from 20 feet away what a person with normal vision can read at 30 feet. The numerator (20) represents the distance in feet between the chart and the client, while the denominator (30) indicates the distance at which a normal eye can read the chart. In this case, Ms. Barrett's vision is slightly worse than normal, as she needs to be closer to the chart to read it clearly. Therefore, choice A is correct. Choices B, C, and D are incorrect: Choice B reverses the distances, Choice C assumes the client can read the entire chart from 30 feet, and Choice D introduces information not related to the 20/30 measurement.

4. A nurse is preparing to test cranial nerve I. Which item does the nurse obtain to test this nerve?

• A. Coffee
• B. A tuning fork
• C. A wisp of cotton
• D. An ophthalmoscope

Correct answer: C

Rationale: To assess the function of cranial nerve I (olfactory nerve), the nurse uses a wisp of cotton to test the sense of smell in a client who reports loss of smell. The nurse assesses the patency of the client's nostrils by occluding one nostril at a time and asking the client to sniff. Next, with the client's eyes closed, the nurse occludes one nostril and presents a non-noxious aromatic substance such as coffee, toothpaste, orange, vanilla, soap, or peppermint. Choice A, 'Coffee,' is incorrect because it is used to present non-noxious aromatic substances to assess cranial nerve I. Choice B, 'A tuning fork,' is used to assess the function of cranial nerve VIII (acoustic nerve). Choice D, 'An ophthalmoscope,' is used to assess the internal structures of the eye, not cranial nerve I.

5. When removing hard contact lenses from an unresponsive client, what should the nurse do?

• A. Gently irrigate the eye with an irrigating solution from the inner canthus outward.
• B. Grasp the lens with a gentle pinching motion.
• C. Don sterile gloves before attempting the procedure.
• D. Ensure that the lens is centered on the cornea before gently manipulating the lids to release the lens.

Correct answer: D

Rationale: When removing hard contact lenses, it is crucial to ensure that the lens is correctly positioned on the cornea before removal. Directly grasping the lens can potentially scratch the cornea, so it is essential to gently manipulate the lids to release the lens safely. Gently irrigating the eye is unnecessary and could be harmful, especially without the client's cooperation. Wearing sterile gloves is also unnecessary for this specific procedure. Therefore, the correct approach is to ensure the proper positioning of the lens and then gently manipulate the lids to release it. Options A and C are incorrect because irrigating the eye and wearing sterile gloves are not necessary for contact lens removal. Option B is incorrect as directly grasping the lens can be harmful to the cornea.
