Nursing Elites

1. A nurse is preparing to screen a client's vision with the use of a Snellen chart. The nurse uses which technique?

• A. Tests the right eye, then tests the left eye, and finally tests both eyes together
• B. Assesses both eyes together, then assesses the right and left eyes separately
• C. Asks the client to stand 40 feet from the chart and read the largest line on the chart
• D. Asks the client to stand 40 feet from the chart and read the line that can be read 200 feet away by someone with unimpaired vision

Correct answer: A

Rationale: To test visual acuity with the use of a Snellen chart, the nurse places the chart in a well-lit spot at the client's eye level, with the client positioned exactly 20 feet from the chart. The client shields one eye at a time with an opaque card during the test. After testing each eye separately, both eyes are assessed together. The client is asked to read the smallest line of letters visible and encouraged to read the next smallest line as well. Therefore, option A is correct as it describes the correct technique of testing one eye at a time before assessing both eyes together. Option B is incorrect as it assesses both eyes together first, which is not the standard procedure. Options C and D are incorrect as they suggest standing 40 feet from the chart, which contradicts the standard distance of 20 feet for a Snellen chart test.

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. When assessing the carotid artery of a client with cardiovascular disease, what action should a nurse perform?

• A. Palpating the carotid artery in the upper third of the neck
• B. Palpating both arteries simultaneously to compare amplitude
• C. Listening to the carotid artery, using the bell of the stethoscope to assess for bruits
• D. Instructing the client to take slow, deep breaths while the nurse listens to the carotid artery

Correct answer: C

Rationale: When assessing the carotid artery of a client with cardiovascular disease, the nurse should listen to the carotid artery using the bell of the stethoscope to assess for bruits. This is crucial in detecting abnormal sounds that may indicate underlying pathology. Palpating the carotid artery in the upper third of the neck can trigger a vagal response, leading to a decrease in heart rate, which is undesirable. Palpating both arteries simultaneously can disrupt blood flow to the brain. Instructing the client to take slow, deep breaths is unnecessary and not a standard practice during carotid artery assessment.

4. A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?

• A. The client is legally blind.
• B. The client has normal vision.
• C. The client can read at a distance of 20 feet what a client with normal vision can read at 80 feet.
• D. The client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.

Correct answer: D

Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20. Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet. Choice A is incorrect because 20/80 does not meet the criteria for legal blindness. Choice B is incorrect as the client's vision is impaired. Choice C is incorrect because it reverses the interpretation of the fraction.

5. When preparing to assist the healthcare provider in examining a client's skin with the use of a Wood light, what action should the nurse perform?

• A. Darken the room
• B. Obtain informed consent from the client
• C. Obtain a scalpel and a slide for diagnostic evaluation
• D. Obtain medication to anesthetize the skin area before proceeding with the examination

Correct answer: A

Rationale: When using a Wood light during a skin examination, the room should be darkened to enhance the visibility of fluorescence. The Wood light emits long-wavelength ultraviolet light, highlighting certain skin conditions. Darkening the room aids in better visualization. Obtaining informed consent is a crucial aspect of healthcare but not directly related to using a Wood light. Obtaining a scalpel and a slide is unnecessary for a noninvasive Wood light examination. Anesthetizing the skin area is not required as the procedure is painless and noninvasive.
