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. A nurse is providing dismissal instructions for a child who was admitted for rotavirus. Which of the following statements by the parent indicates the need for further teaching?

A. I'll start giving him his antibiotics as soon as we get home.
B. I will call the physician if he becomes dizzy or overly fussy.
C. He will need to wash his hands a lot to keep this from spreading.
D. I'll watch to see when he stops having diarrhea stools.

Correct answer: A

Rationale: The correct answer is 'I'll start giving him his antibiotics as soon as we get home.' Rotavirus is a viral illness, and antibiotics are ineffective for its treatment. The parent's statement indicates a need for further teaching as antibiotics are not appropriate for treating rotavirus. Option B is correct as it demonstrates the parent's understanding of when to contact the physician for concerning symptoms. Option C is a correct statement regarding infection control practices. Option D is also correct as monitoring diarrhea stools is essential to track recovery from rotavirus.

3. Who among the following individuals wrote a medical code of ethics?

A. Hammurabi
B. Thomas Percival
C. Hippocrates
D. All of the above

Correct answer: D

Rationale: All of the above individuals contributed to the development of medical ethics. Hammurabi created the earliest known code around 2500 BC. Hippocrates, known for the principle 'Do no harm,' emphasized ethical practices in medicine. Thomas Percival, a physician interested in sociological medicine, authored a Code of Medical Ethics in 1803, which influenced modern medical ethics. Therefore, the correct answer is 'All of the above.' Choices A, B, and C are incorrect because each of them individually wrote a medical code of ethics, making 'All of the above' the most inclusive and accurate answer.

4. The client is being educated about depression by the nurse. Which statement by the client indicates that the teaching has been effective?

A. ''All elderly individuals experience depression occasionally.''
B. ''I'm relieved that I will improve within 2 or 3 days.''
C. ''I never realized depression could occur without a specific cause.''
D. ''Reducing stress in my life will alleviate the depression.''

Correct answer: C

Rationale: The correct answer, 'I never realized depression could occur without a specific cause,' demonstrates an understanding that depression can arise without a clear trigger, indicating effective teaching. Choice A is incorrect because not all elderly individuals experience depression, and this statement doesn't show understanding. Choice B is incorrect as it reflects a misconception about the quick resolution of depression. Choice D is incorrect as it oversimplifies the relationship between stress reduction and depression resolution.

5. A client returns from surgery after having a colon resection. The nurse is performing an assessment and notes the wound edges have separated. This condition is called:

A. Evisceration
B. Hematoma
C. Dehiscence
D. Granulation

Correct answer: C

Rationale: Wound dehiscence occurs when the edges of a wound pull apart. The condition may occur following a surgical procedure if the sutures were deficient. Wound dehiscence may also occur following a wound infection or in cases where a client significantly stretches or overuses the associated tissues. Evisceration refers to the protrusion of internal organs through an open wound. Hematoma is a localized collection of blood outside the blood vessels. Granulation is the formation of new connective tissue and tiny blood vessels on the surface of a wound during the healing process.
