NCLEX RN Exam Preview Answers
1. The nurse is preparing to examine a 4-year-old child. Which action by the nurse is appropriate for this age group?
- A. Explain the procedures briefly to alleviate the child's anxiety.
- B. Give the child feedback and reassurance during the examination.
- C. Ask the child to undress as needed for the examination.
- D. Perform an examination of the head last.
Correct answer: B
Rationale: For a 4-year-old child, short and simple explanations should be provided to avoid overwhelming the child. It is important to give feedback and reassurance during the examination to create a comforting environment for the child. Asking the child to undress as needed is appropriate for a thorough examination, as children at this age are usually willing to do so. Performing an examination of the head last allows the child to become more comfortable during the assessment. Therefore, the most appropriate action for a 4-year-old child is to provide feedback and reassurance during the examination, ensuring a positive experience for the child.
2. When performing an EKG, the patient starts to laugh out of feelings of anxiety. What would you expect the EKG to show? (Choose the BEST answer.)
- A. Increased pulse rate, normal EKG
- B. Decreased pulse rate, abnormal EKG
- C. Tachycardia, poor EKG graph
- D. Bradycardia, poor EKG graph
Correct answer: C
Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.
3. 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.
4. Mrs. D is a pregnant client who is 33 weeks' gestation and is admitted for bright red vaginal bleeding. Her physician suspects placenta previa. All of the following nursing interventions are appropriate for this client except:
- A. Institute complete bed rest for the client
- B. Assess uterine tone to determine condition
- C. Perform a vaginal exam to assess cervical dilation
- D. Measure and record blood loss each shift
Correct answer: C
Rationale: A client with placenta previa has part of the placenta covering some or all of the cervical opening. Performing a vaginal exam for placenta previa may cause significant bleeding and should be avoided unless directed by a physician, and preparations are made for emergency delivery. **Choice A** is correct as complete bed rest is essential to decrease the risk of further bleeding. **Choice B** is appropriate as assessing uterine tone helps in determining the condition of the uterus and can provide important information for the healthcare team. **Choice D** is also a necessary intervention as monitoring and recording blood loss is crucial in assessing the client's condition and response to treatment.
5. The nurse is assessing the vital signs of a 20-year-old marathon runner and documents the following vital signs: temperature"?36�C; pulse"?48 beats per minute; respirations"?14 breaths per minute; blood pressure"?104/68 mm Hg. Which statement is true concerning these results?
- A. The patient is experiencing bradycardia.
- B. These are normal vital signs for a healthy, athletic adult.
- C. The patient's pulse rate is not normal"?no action is required.
- D. The patient's next clinic visit should occur as scheduled.
Correct answer: B
Rationale: The correct answer is, 'These are normal vital signs for a healthy, athletic adult.' A pulse rate of 48 beats per minute is considered bradycardia in adults, but it is not a concern in well-trained athletes like marathon runners. Bradycardia is a normal physiological response to aerobic conditioning. Tachycardia, on the other hand, is defined as a pulse rate above 100 beats per minute, which is not the case here. The low pulse rate in this scenario is a reflection of the athlete's cardiovascular fitness. Therefore, there is no need to notify the physician or schedule a follow-up visit based on these findings.
