NCLEX RN Predictor Exam
1. After performing the appropriate client assessment, which of the following inferences would the nurse make?
- A. Client is hypotensive
- B. Respiratory rate of 20 breaths per minute
- C. Oxygen saturation of 95%
- D. Client relays anxiety about blood work
Correct answer: A
Rationale: An inference is the nurse's judgment or interpretation of cues gathered during an assessment. In this scenario, identifying a client as hypotensive would be an inference based on blood pressure readings that indicate lower than normal values. Respiratory rate and oxygen saturation levels (choices B and C) are important cues that provide additional data but do not directly point to a specific conclusion like hypotension. The client expressing anxiety about blood work (choice D) is relevant information but relates more to their emotional state rather than a physiological assessment finding.
2. A patient is having difficulty understanding how to properly run her glucose meter. Which of the following teaching methods would best help the patient understand how to use her instrument correctly?
- A. Give the patient an instruction booklet and encourage her to call the office if she has questions.
- B. Tell the patient to ask a healthcare provider to demonstrate how to use the instrument.
- C. Have the patient watch a video demonstrating the use of the instrument.
- D. Demonstrate the proper use of the instrument and then have the patient perform the process while still in the office.
Correct answer: D
Rationale: By using a demonstration and performance method of patient education, the patient is offered a chance to perform a task and have learning assessed while still in the office. This ensures that any questions that the patient has can be answered immediately, and any performance issues observed by the medical assistant can also be corrected promptly. Choice A is not as effective as providing a demonstration in person, as it may not address the patient's specific learning needs or allow for immediate feedback. Choice B suggests asking a healthcare provider to demonstrate, which is similar to the correct answer but may not always be readily available in the office. Choice C, watching a video, lacks the interactive component and immediate feedback that a live demonstration provides, making it less effective in this scenario.
3. Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)
- A. HCV
- B. HPV
- C. HIV
- D. HBV
Correct answer: A
Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.
4. Cheryl M. has a serious swallowing disorder. She has asked you for a glass of water. The doctor has ordered honey thickness liquids for her. Water is not a honey thickness liquid. It is much thinner. What should you do?
- A. Tell the resident that she cannot have water.
- B. Give her applesauce instead of the water.
- C. Tell Cheryl that she is NPO until midnight.
- D. Thicken the water and give it to her.
Correct answer: D
Rationale: You can give Cheryl the water that she has requested; however, since water is not a honey-thick liquid as ordered by the doctor, you must thicken it with a commercial thickener before giving it to her. This will ensure that the water is at the appropriate consistency for her swallowing disorder. Choices A, B, and C are incorrect: A) Telling the resident she cannot have water is not the best course of action without attempting to modify it first. B) Giving her applesauce instead of water does not address the specific request for water. C) Placing Cheryl on NPO status until midnight is unnecessary and does not address her immediate request for water.
5. 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.
