NCLEX RN Practice Questions With Rationale

1. What is the purpose of performing quality control?

A. Create a paper trail to show that the laboratory is compliant with OSHA standards for quality control.
B. Improve the odds that the results reported for any given test are as accurate and reliable as possible.
C. Be required by law to be part of a quality assurance program.
D. All of the above

Correct answer: B

Rationale: The primary purpose of performing quality control is to enhance the accuracy and reliability of test results. Quality controls are crucial for ensuring the reliability of each analyte tested. While quality control is not mandated by specific laws, accrediting bodies often require it to maintain accreditation. Creating a paper trail and legal requirements are not the primary objectives of quality control, making choices A and C incorrect. Therefore, the correct answer is to improve the accuracy and reliability of reported test results.

2. Which of the following is an example of whistle-blowing?

A. A nurse contacts administration about a colleague who takes supplies to use for a mission trip
B. A client sues a nurse because she failed to call the physician about his wound infection
C. A nursing assistant calls for help when a client falls out of bed
D. A client developed a sacral pressure ulcer when he was not turned in bed for over four hours

Correct answer: A

Rationale: Whistle-blowing involves notifying administration or a supervisor about unethical or illegal activities. In this scenario, the nurse reporting a colleague taking supplies for personal use is an example of whistle-blowing as it involves reporting behavior that is dishonest and potentially harmful. Choices B, C, and D do not represent whistle-blowing. Choice B involves a legal action by a client against a nurse, choice C is a situation where immediate care is provided, and choice D is a case of neglect that should have been prevented.

3. Your patient has been diagnosed with a left ankle sprain. On the discharge instructions, the physician has prescribed the RICE protocol. This acronym stands for:

A. Rest, Ice, Compression, Elevation
B. Radiology, Ice, Compression, Elevation
C. Rest, Ice, Cast, Elevation
D. Radiology, Ice, Cast, Elevation

Correct answer: A

Rationale: The correct answer is Rest, Ice, Compression, Elevation. This acronym, RICE, is commonly used for the treatment of injuries like an ankle sprain. Rest allows the injured area to heal, Ice helps reduce swelling and pain (20 minutes on each hour while awake), Compression is usually achieved with an elastic bandage to minimize swelling, and Elevation of the foot above the level of the heart assists in reducing swelling and promoting healing. Choices B, C, and D are incorrect because they include irrelevant terms like Radiology and Cast, which are not part of the standard treatment protocol for an ankle sprain.

4. Which of the following screening tools have been found to have high diagnostic accuracy for screening for intimate partner violence?

A. Hurt, Insult, Threaten, and Scream (HITS)
B. Humiliation, Afraid, Rape, and Kick (HARK)
C. Slapped, Threatened, and Thrown (STaT)
D. All of the above

Correct answer: D

Rationale: All of the above screening tools, including HITS, HARK, and STaT, have been found to have high diagnostic accuracy for screening intimate partner violence, as per the National Preventive Services Task Force. These tools are effective in identifying current or recent intimate partner violence. While the Partner Violence screen may have some predictive value for future intimate partner violence, the question specifically focuses on screening tools with high diagnostic accuracy, making 'All of the above' the correct choice. Choices A, B, and C are specific validated screening tools for intimate partner violence, each with its own set of questions that have been shown to be effective in identifying individuals experiencing intimate partner violence. Therefore, 'All of the above' is the most comprehensive and accurate choice for this question.

5. Asepsis is defined as ________________.

A. the absence of all microorganisms
B. the absence of disease-causing germs
C. a urinary infection
D. a pathogenic infection

Correct answer: B

Rationale: Asepsis is defined as the absence of disease-causing germs. It is surgical asepsis that is defined as the absence of all microorganisms, including spores. A pathogenic infection is an invasion of the body by a pathogen, or disease-causing germ, and a urinary infection is only one type of infection.
