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 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.

3. A patient with bipolar disorder asks the nurse, "Why did I get this illness? I don't want to be sick."? The nurse would best respond with:

A. People who develop mental illnesses often had a very traumatic childhood experience.
B. There is some evidence that contracting a virus during childhood can lead to mental disorders.
C. Sometimes people with mental illness have an overactive immune system.
D. We don't fully understand the cause, but mental illnesses do seem to run in the family.

Correct answer: D

Rationale: The correct response is, 'We don't fully understand the cause, but mental illnesses do seem to run in the family.' Current research suggests that while genetics play a role in the development of mental illnesses like bipolar disorder, it is not the sole factor. Environmental influences, life experiences, and other non-genetic factors also contribute significantly to the manifestation of mental disorders. Choices A, B, and C provide incorrect information that is not supported by current research. Traumatic childhood experiences, contracting a virus during childhood, and an overactive immune system are not established causes of bipolar disorder or mental illnesses in general.

4. Which of the following situations might warrant a laboratory magnesium level?

A. Hyperthyroidism
B. Arthritis
C. Ulcerative colitis
D. Depression

Correct answer: C

Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.

5. A client is discharged following hospitalization for congestive heart failure. The nurse teaching the family suggests they encourage the client to rest frequently in which of the following positions?

A. High Fowler's
B. Supine
C. Left lateral
D. Low Fowler's

Correct answer: A

Rationale: The correct answer is "High Fowler's" position. Sitting in a chair or resting in a bed in a high Fowler's position decreases the cardiac workload and facilitates breathing. This position helps reduce the work of breathing and promotes optimal lung expansion, making it easier for the client to breathe. Supine position (choice B) is lying flat on the back and may not be ideal for clients with congestive heart failure as it can increase pressure on the heart. Left lateral position (choice C) is commonly used for promoting circulation in clients with certain conditions but is not the most appropriate for congestive heart failure. Low Fowler's position (choice D) is not recommended as it does not provide the same benefits in terms of reducing cardiac workload and easing breathing as the high Fowler's position.
