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. According to HIPAA, which of the following is considered an individual right for privacy of a client's protected health information?

A. The right to receive a copy of the organization's privacy practices
B. The right to receive medical bills for care received
C. The right to change personal health information
D. An understanding that protected health information will only be used in regards to client treatments

Correct answer: A

Rationale: According to HIPAA, individuals receiving care at healthcare facilities have rights surrounding their protected health information. One of these rights is to receive a copy of the organization's privacy practices, which outlines how their health information will be used and protected. This ensures transparency and allows individuals to understand how their information is handled. The other choices are incorrect because while individuals have the right to access their health information, receive explanations of how it is used, and ensure its confidentiality, receiving medical bills or changing personal health information are not specifically outlined as rights related to the privacy of protected health information.

3. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
C. The client should lie flat on their back for a specific period following the procedure.
D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

4. Which of the following is a function of risk management?

A. To consider the problems that arise if errors happen and their effects on the healthcare environment
B. To identify how nursing care responds to specific client problems
C. To view clients as customers and decide what actions will provide a satisfying healthcare experience
D. To analyze physician-nurse relationships and determine where collaboration efforts can improve

Correct answer: A

Rationale: The function of risk management in healthcare is to assess and address potential risks that could lead to errors and their effects on the healthcare environment. This involves identifying, evaluating, and prioritizing risks to minimize their impact and prevent adverse outcomes. Choice A is correct because it aligns with the core purpose of risk management in healthcare. Choices B, C, and D are incorrect as they do not directly relate to the primary focus of risk management, which is the proactive management of risks to ensure patient safety and quality care.

5. The BRAT diet is often prescribed for patients with gastroenteritis. This acronym stands for:

A. Bananas, Rice, Applesauce, and Toast
B. Bread, Rice, Apricots, and Tapioca
C. Bananas, Rolls, Apricots, and Toast
D. Bananas, Rolls, Applesauce, and Tapioca

Correct answer: A

Rationale: The BRAT diet, which stands for Bananas, Rice, Applesauce, and Toast, is commonly recommended for patients with gastroenteritis. These easily digestible foods help firm up stools due to their low fiber content and provide essential nutrients lost during vomiting and diarrhea. Choice B is incorrect because it includes apricots, which are not part of the traditional BRAT diet. Choice C is incorrect as it includes rolls, which are not typically included in the BRAT diet. Choice D is incorrect as it includes tapioca, which is not part of the traditional BRAT diet. Therefore, the correct answer is Bananas, Rice, Applesauce, and Toast.
