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 of these guidelines would a healthcare professional follow when measuring a patient's weight?
- A. The patient is always weighed wearing only undergarments.
- B. The type of scale matters and should be consistent day to day.
- C. The patient should remove heavy outer clothing, shoes, and jackets before weighing.
- D. Attempts should be made to weigh the patient at approximately the same time of day if a sequence of weights is necessary.
Correct answer: D
Rationale: When measuring a patient's weight, it is important to ensure accuracy and consistency. If a sequence of repeated weights is necessary, the healthcare professional should attempt to weigh the patient at the same time of day and with the same types of clothing worn each time. It is crucial to use a standardized balance or electronic standing scale for accurate weight measurement. Choice A is incorrect as patients should remove heavy outer clothing, shoes, and jackets before being weighed for accurate results. Choice B is incorrect because the type of scale used does matter and should be consistent for reliable weight tracking. Choice C is incorrect as patients should not leave on heavy outer clothing, shoes, or jackets as these items can add to the weight recorded inaccurately.
3. Which of the following organs would be described as being located retroperitoneally?
- A. Kidneys
- B. Thymus
- C. Small Intestines
- D. Spleen
Correct answer: A
Rationale: The term 'retroperitoneal' refers to organs positioned behind the peritoneum. The kidneys are retroperitoneal organs, located outside the peritoneal cavity, against the posterior abdominal wall. This positioning provides them with additional protection from external forces due to the surrounding structures. The thymus, small intestines, and spleen are not retroperitoneal organs. The thymus is located in the mediastinum, the small intestines are intraperitoneal, and the spleen is intraperitoneal and located in the left upper quadrant of the abdomen.
4. When percussing over the abdomen of an obese patient, the nurse is unable to identify any changes in sound. What would the nurse do next?
- A. Ask the patient to take deep breaths to relax the abdominal musculature.
- B. Consider this finding as normal and proceed with the abdominal assessment.
- C. Increase the amount of strength used when attempting to percuss over the abdomen.
- D. Decrease the amount of strength used when attempting to percuss over the abdomen.
Correct answer: C
Rationale: When percussing an obese patient's abdomen, the thickness of their body wall can affect the sound produced. A stronger percussion stroke is needed for obese or very muscular patients. The force of the blow determines the loudness of the note. Asking the patient to take deep breaths, considering the finding as normal, or decreasing the strength used are not appropriate actions in this scenario.
5. A client is preparing to administer an enema to a 64-year-old client. Which of the following actions of the nurse is most appropriate?
- A. Assist the client to lie in the semi-Fowler position
- B. Apply lubricating jelly to the tip of the catheter before insertion
- C. Instill a total of 30cc of fluid into the client's rectum
- D. Ask the client to hold the solution in for 30 seconds
Correct answer: B
Rationale: When administering an enema to a client, the nurse should place the client in the Sims' position for easy access. The correct action is to apply lubricating jelly to the tip of the catheter before insertion to facilitate a smoother procedure. It is essential to instill a maximum of 750 to 1000 cc of fluid for an adult client, not just 30cc. Following administration, the nurse should ask the client to hold the solution for at least 5 minutes to allow for the desired effect of the enema. Therefore, choice B is the most appropriate action, as choices A, C, and D are incorrect due to inaccuracies in positioning, enema volume, and retention time.
