NCLEX RN Predictor Exam
1. 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.
2. What are Korotkoff sounds?
- A. Sounds noted during diastole.
- B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
- C. Sounds only noted by skilled cardiologists.
- D. Distinct sounds which are classified into 6 phases.
Correct answer: B
Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.
3. Which of these techniques uses the sense of touch to assess texture, temperature, moisture, and swelling when assessing a patient?
- A. Palpation
- B. Inspection
- C. Percussion
- D. Auscultation
Correct answer: A
Rationale: The correct answer is Palpation. Palpation involves using the sense of touch to assess texture, temperature, moisture, and swelling in a patient. This technique allows the nurse to feel for abnormalities and changes in the patient's tissues. Inspection primarily relies on visual assessment, while percussion involves tapping on the body to produce sounds and assess underlying structures. Auscultation, on the other hand, involves listening to sounds within the body using a stethoscope. Therefore, in the context of assessing texture, temperature, moisture, and swelling, palpation is the most appropriate technique.
4. Mr. Thomas is a well-groomed 68-year-old male patient who had prostate surgery two days ago. He has an indwelling catheter and a urinary drainage bag. You have weighed him at 9 am each morning for 3 mornings in a row. Today, on the 4th day, his morning weight is 3 pounds more than it was the day before. Why could he have gained these 3 pounds in one day, on a 1000 calorie diet?
- A. It is obvious that his visitors have been sneaking him junk food from the local fast-food restaurant.
- B. It may be that his urinary drainage bag was not emptied today and it was emptied on previous days.
- C. It is obvious that the scale is broken and it should be replaced immediately to prevent these false weights.
- D. A 3-pound weight gain is not significant enough to question and should just be noted.
Correct answer: B
Rationale: The correct answer is that the weight gain may be due to the urinary drainage bag not being emptied today, while it was emptied on previous days. This scenario is common and can lead to an increase in weight that is not related to food intake. Choice A is incorrect because assuming visitors are sneaking junk food is speculative and not based on facts. Choice C is incorrect as there is no evidence to suggest the scale is broken. Choice D is incorrect because any unexplained weight gain should be investigated further, even if it seems insignificant at first.
5. During the implementation phase of the nursing process when working with a hospitalized adult, which of the following actions would the nurse take?
- A. Formulate a nursing diagnosis of impaired gas exchange
- B. Record in the medical record the distance a client ambulates in the hall
- C. Write individualized nursing orders in the care plan
- D. Compare client responses to the desired outcomes for pain relief
Correct answer: B
Rationale: During the implementation phase of the nursing process, the nurse is responsible for carrying out or delegating nursing interventions and documenting nursing activities and client responses in the medical records. Option A involves diagnosing, which is part of the nursing process's earlier phases. Option C pertains to planning, which precedes implementation. Option D relates to evaluation, which comes after the implementation phase.
