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. What ethical principle has led to the need for informed consent?

A. Autonomy
B. Justice
C. Fidelity
D. Beneficence

Correct answer: A

Rationale: Autonomy is the ethical principle that emphasizes an individual's right to make their own decisions if they are mentally competent. Informed consent is a direct result of this principle, as it ensures that patients are fully informed before agreeing to any medical intervention. Autonomy is crucial in healthcare as it respects patients' rights and promotes self-determination. Justice, fidelity, and beneficence are important ethical principles in healthcare, but they do not directly lead to the need for informed consent. Justice focuses on fairness and equal treatment, fidelity on trustworthiness and loyalty, and beneficence on doing good for the patient's benefit.

3. A child has recently been diagnosed with Duchenne muscular dystrophy (DMD). The parents are receiving genetic counseling prior to planning another pregnancy. Which of the following statements includes the most accurate information?

A. Duchenne is an X-linked recessive disorder, so daughters have a 50% chance of being carriers and sons a 50% chance of developing the disease.
B. Duchenne is an X-linked recessive disorder, so both daughters and sons have a 50% chance of developing the disease.
C. Each child has a 1 in 4 (25%) chance of developing the disorder.
D. Sons only have a 1 in 4 (25%) chance of developing the disorder.

Correct answer: A

Rationale: The correct answer is that Duchenne is an X-linked recessive disorder, meaning the affected gene is located on one of the two X chromosomes of a female carrier. If a son receives the X chromosome bearing the gene, he will develop the disease, giving him a 50% chance of being affected. Daughters, on the other hand, are not affected by Duchenne but have a 50% chance of being carriers since they inherit one copy of the defective gene from the mother. The other X chromosome is inherited from the father, who cannot be a carrier. Therefore, choice A is accurate. Choice B is incorrect because daughters do not develop the disease, and sons have a 50% chance of developing, not both having a 50% chance. Choice C is incorrect as it does not consider the X-linked inheritance pattern of Duchenne. Choice D is inaccurate as it incorrectly states that only sons have a 25% chance of developing the disorder, omitting the carrier status of daughters.

4. A victim of a gunshot wound to the abdomen has been admitted to the hospital, accompanied by a police officer. When questioned, the officer states that the patient is a suspect in a homicide, which occurred as part of the same incident. A small child was killed as the result of a stray bullet. The patient is combative, yells that he's in pain and demands medication. What is your most appropriate response?

A. Tell him you'll take care of him after your other patients
B. Reinforce restraints
C. Perform a pain assessment and administer pain medication
D. Ask the officer for more details of the incident

Correct answer: C

Rationale: The most appropriate and caring response is to perform a pain assessment and administer the pain medication that has been ordered. Regardless of personal feelings about any given situation, the nurse's responsibility is to provide unbiased, appropriate, and supportive care, as stated in the American Nurses Association (ANA) Code of Ethics. Choice A is not appropriate as it disregards the patient's immediate need for pain relief. Choice B may escalate the situation and is not the priority in this case. Choice D is not the immediate action needed to address the patient's pain and distress.

5. Plantar flexion can be prevented with ________________.

A. foot soaks
B. foot boards
C. toenail care
D. proper shoes

Correct answer: B

Rationale: Plantar flexion, or foot drop, can be prevented with foot boards, special splints, and range of motion exercises. Foot boards help maintain the foot in a neutral position, preventing contractures and deformities. Foot soaks (choice A) may help with foot hygiene but do not directly prevent plantar flexion. Toenail care (choice C) is important for overall foot health but does not prevent plantar flexion. Proper shoes (choice D) are essential for foot support and comfort but do not specifically prevent plantar flexion.
