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 caring for a client taking Lipitor (Atorvastatin). Which of these statements would indicate that the client may need reinforced teaching?

• A. "I take my Lipitor with a glass of milk after my breakfast."?
• B. "I take my Lipitor and wait 30 minutes before taking my other medications."?
• C. "I take my Lipitor 30 minutes after I eat something."?
• D. "I take my Lipitor and my other morning medications with my grapefruit juice at breakfast."?

Correct answer: D

Rationale: The correct answer is, 'I take my Lipitor and my other morning medications with my grapefruit juice at breakfast.' This statement indicates a need for reinforced teaching because grapefruit juice should be avoided when taking Lipitor. Grapefruit juice blocks the enzymes needed to break down the drug, which leads to excessive amounts of the drug in the body. Choices A, B, and C show appropriate timing and administration of Lipitor, whereas choice D poses a potential risk due to the interaction between grapefruit juice and Lipitor.

3. A nurse demonstrates the procedure for bathing a newborn to a new mother. The next day, the nurse watches as the mother bathes the infant. The nurse determines that the mother is performing the procedure correctly if the mother performs which action?

• A. Uses a cotton-tipped swab to carefully clean inside the infant's nose
• B. Uncovers only the body part being washed
• C. Washes the diaper area first
• D. Washes the infant's chest first

Correct answer: B

Rationale: When bathing a newborn, it is crucial to follow a specific sequence for thorough cleaning and safety. The correct sequence includes starting with the eyes and face, then moving to the external ear, areas behind the ears, neck, hands, arms, legs, and finally the diaper area. Keeping the infant warm is essential, so only the body part being washed should be uncovered. Using a cotton-tipped swab to clean inside the infant's nose is not recommended due to the risk of injury if the infant moves suddenly. Washing the diaper area first is incorrect as it should be done towards the end of the bath to prevent contamination. Washing the infant's chest first is also incorrect as it deviates from the recommended bathing sequence for a newborn.

4. 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.

5. The client has an order for a 1,000 mL bag of fluids to be infused over 8 hours. What is the correct rate?

• A. 100 mL/hr
• B. 125 mL/min
• C. 125 mL/hr
• D. 80 mL/min

Correct answer: C

Rationale: To determine the correct infusion rate, divide the total volume of fluids (1,000 mL) by the total infusion time (8 hours), resulting in a rate of 125 mL/hr. This calculation ensures the appropriate administration of fluids over the specified time period. Choice A (100 mL/hr) is incorrect as it does not match the calculated rate based on the given information. Choice B (125 mL/min) is inaccurate because the question specifies the rate in hours, not minutes. Choice D (80 mL/min) is incorrect as it provides the rate in minutes rather than hours, which is the required unit for this scenario.
