NCLEX RN Exam Preview Answers
1. An examiner is using an ophthalmoscope to examine a patient's eyes. The patient has astigmatism and is nearsighted. Which of these techniques by the examiner would indicate that the examination is being correctly performed?
- A. Rotating the lens selector dial to bring the object into focus
- B. Using the large full circle of light when assessing pupils that are not dilated
- C. Rotating the lens selector dial to the black numbers to compensate for astigmatism
- D. Using the grid on the lens aperture dial to visualize the external structures of the eye
Correct answer: A
Rationale: To correctly perform an eye examination using an ophthalmoscope on a patient with astigmatism and nearsightedness, the examiner should rotate the lens selector dial to bring the object into focus. This adjustment helps compensate for nearsightedness or farsightedness but does not correct astigmatism. Rotating the lens selector dial to the black numbers is not an appropriate technique for compensating for astigmatism. Using the grid on the lens aperture dial is primarily for visualizing external structures of the eye, not for addressing refractive errors. The large full circle of light is typically used when assessing dilated pupils, not for examining patients with astigmatism and nearsightedness. Therefore, the correct technique is rotating the lens selector dial to bring the object into focus.
2. Which practice will help reduce the risk of a needlestick injury?
- A. Expose the end of the needle only when ready to enter the room for the procedure
- B. Never recap a needle after use
- C. Keep a sharps container nearby where it can be easily accessed
- D. Exchange needles from a central area rather than passing them between workers
Correct answer: C
Rationale: To reduce the risk of a needlestick injury, it is essential to keep a sharps container nearby where it can be easily accessed. This practice ensures quick and safe disposal of needles after use, minimizing the chances of accidental needlesticks. Recapping needles should be avoided as it increases the risk of injuries. Passing needles between workers should also be avoided to prevent accidental needle pricks during handovers. Therefore, the best practice to prevent needlestick injuries is to maintain a sharps container nearby for safe and immediate disposal of needles.
3. Which of the following is part of client teaching regarding antiembolism stockings?
- A. Instruct the client to roll the top portion of the stocking down if it is too long
- B. Stockings are applied with the toes uncovered at the end
- C. Measure for thigh-high stockings from the foot to the knee
- D. Stockings are to be smooth from end to end without wrinkles
Correct answer: D
Rationale: When educating clients about antiembolism stockings, it is essential to emphasize that the stockings should be smooth from end to end without wrinkles. Wrinkles in the stockings can impede circulation, defeating the purpose of wearing them to prevent blood clot formation. Instructing the client to roll the top portion of the stocking down if it is too long (Choice A) is incorrect as it can create unnecessary pressure points. Stockings should be applied with the toes covered at the end (Choice B) to ensure proper compression. Measuring for thigh-high stockings should be done from the knee to the foot (Choice C) to ensure the correct fit and compression gradient.
4. Before allowing the client's infant granddaughter to visit before the client's scheduled heart transplant, the nurse decides it would be beneficial to collaborate with which of the following? Select all that apply.
- A. Client and Family
- B. Other nursing staff on the unit
- C. Security department
- D. Hospital administration
Correct answer: B
Rationale: Collaborating with the client and family is crucial as it fosters a sense of autonomy and active involvement in the healthcare process for the client. Involving other nursing staff ensures the successful implementation of the planned intervention and provides support for the client's needs. Collaboration with the security department or hospital administration is not necessary in this situation, as the focus should be on the client's well-being and family involvement during a sensitive time.
5. The healthcare professional notices that a colleague is preparing to check the blood pressure of a patient who is obese by using a standard-sized blood pressure cuff. How would this likely affect the blood pressure reading?
- A. Yield a falsely low blood pressure
- B. Yield a falsely high blood pressure
- C. Be the same, regardless of cuff size
- D. Vary as a result of the technique of the person performing the assessment
Correct answer: B
Rationale: Using a cuff that is too narrow for an obese patient would likely yield a falsely high blood pressure reading. This occurs because the standard cuff is too small for the arm's circumference, requiring more pressure to compress the artery. A tight cuff can lead to inaccurate and elevated blood pressure readings. Choices A, C, and D are incorrect because using an improperly sized cuff would not yield a falsely low blood pressure, the blood pressure reading does vary with cuff size, and the technique of the person performing the assessment is not the primary factor affecting the reading in this situation.
