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. While assessing a one-month-old infant, which of the findings does not warrant further investigation by the nurse?

A. Abdominal respirations
B. Inspiratory grunt
C. Nasal flaring
D. Cyanosis

Correct answer: A

Rationale: Abdominal respirations in infants are considered normal due to the underdeveloped intercostal muscles. Infants rely more on their abdominal muscles to facilitate breathing since their intercostal muscles are not fully matured. Therefore, abdominal respirations do not typically require further investigation. Inspiratory grunt, nasal flaring, and cyanosis are findings that warrant additional assessment as they can indicate potential respiratory distress or other underlying health issues in infants. Inspiratory grunt may suggest respiratory distress, nasal flaring can be a sign of increased work of breathing, and cyanosis indicates poor oxygenation, all of which require prompt evaluation and intervention to ensure the infant's well-being.

3. Which of the following is an example of intrapersonal conflict?

A. A nurse feels guilty when she administers essential medication that causes a client to have nausea and vomiting
B. A nurse is called to testify in court about a client she cared for three years ago
C. A nurse feels guilty for working overtime
D. A nurse faces a conflict with a colleague over patient care decisions

Correct answer: A

Rationale: Intrapersonal conflict involves negative feelings or frustrations within oneself. It may be related to decisions or actions that clash with personal morals or beliefs. Choice A is the correct answer because the nurse is experiencing guilt due to administering medication that causes a client to have negative side effects, which reflects an internal struggle. Choices B, C, and D do not represent intrapersonal conflict. Choice B involves a legal obligation, Choice C is related to external factors like working overtime, and Choice D pertains to a conflict with a colleague.

4. An 18-year-old male patient informs the nurse that he isn't sure if he is homosexual because he is attracted to both genders. The nurse establishes a trusting relationship with the patient by saying:

A. Don't worry. It's just a phase you will grow out of.
B. Those are abnormal impulses. You should seek therapy.
C. At your age, it is normal to be curious about both genders.
D. Having questions about sexuality is normal. Have you noticed any changes in the way this makes you feel about yourself?

Correct answer: C

Rationale: It is important for the nurse to validate the patient's concerns and provide a supportive environment. By acknowledging that it is normal for young adults to have questions about sexuality, the nurse helps the patient feel understood and accepted. This response encourages further discussion and exploration of the patient's feelings without judgment. Choice A dismisses the patient's concerns and implies that his feelings are not valid. Choice B stigmatizes the patient's feelings by labeling them as abnormal and suggests therapy without proper assessment. Choice D addresses the patient's feelings but lacks the validation and reassurance present in the correct answer, which is essential in building a trusting relationship with the patient.

5. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

A. External light sources may cause falsely high oximetry values
B. A bright light in the client's face may cause a low pulse oximetry
C. External light sources may cause falsely low oximetry values
D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.
