NCLEX RN Exam Preview Answers
1. The nurse is examining a 2-year-old child and asks, "May I listen to your heart now?"? Which critique of the nurse's technique is most accurate?
- A. Asking questions may enhance the child's autonomy.
- B. Asking the child for permission helps develop a sense of trust.
- C. This question is an inappropriate statement because children at this age like to have choices.
- D. Children at this age like to say, "No."? The examiner should not offer a choice when no choice is available.
Correct answer: D
Rationale: Children at the age of 2 often like to assert their independence by saying "No."? In situations where there is actually no choice available, offering a false choice can lead to a lack of trust. It is important not to offer a choice when there isn't one, as doing so may undermine trust. While asking for permission can enhance autonomy and trust, offering a limited option like, "Shall I listen to your heart next or your tummy?"? may be a better approach. Therefore, the correct critique of the nurse's technique in this scenario is that children at this age tend to say "No,"? so the examiner should avoid offering a choice when there isn't a real alternative.
2. Which acronym would BEST describe the procedure for assessing a patient that appears unconscious?
- A. WBC
- B. QRS
- C. XYZ
- D. ABC
Correct answer: D
Rationale: The correct answer is D, 'ABC.' The ABC method stands for Airway, Breathing, Circulation. When encountering an unconscious patient, it is crucial to first ensure their Airway is clear by performing the 'head tilt, chin lift' maneuver. Next, assess Breathing by observing for chest rise and fall, listening for breath sounds, and feeling for airflow. Finally, check for Circulation by assessing for a pulse. Choices A, B, and C ('WBC,' 'QRS,' 'XYZ') are incorrect as they do not represent the standard approach to assessing an unconscious patient.
3. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?
- A. Alert the physician immediately as this is a sign of impending cardiac arrest.
- B. Check to see that all leads are attached and rerun the EKG.
- C. Increase the sensitivity control to 20 mm deflection.
- D. Decrease the run speed to 50.
Correct answer: C
Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
4. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?
- A. Controls stray electrical currents.
- B. Promotes efficient use of electricity.
- C. Shuts off the appliance if there is an electrical surge.
- D. Divides the electricity among the appliances in the room.
Correct answer: A
Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.
5. What is the flap of tissue that covers the trachea upon swallowing called?
- A. Epidermis
- B. Endocardium
- C. Epiglottis
- D. Epistaxis
Correct answer: C
Rationale: The correct answer is C: Epiglottis. The epiglottis is a flap of tissue that covers the trachea when swallowing to prevent food or liquid from entering the airway. Choice A, Epidermis, is the outer layer of the skin and is not related to the trachea. Choice B, Endocardium, is the inner lining of the heart chambers and is also unrelated to the trachea. Choice D, Epistaxis, refers to a nosebleed and is not the correct term for the tissue covering the trachea.
