NCLEX RN Practice Questions Quizlet
1. A client must use a non-rebreathing oxygen mask. Which of the following statements is true regarding this type of mask?
- A. A non-rebreather can provide an FiO2 of 40%.
- B. A client should breathe through his or her mouth when using a non-rebreather.
- C. A non-rebreather offers a reservoir from which the client inhales.
- D. The mask of a non-rebreather should be changed every 3 hours.
Correct answer: A
Rationale: A non-rebreather mask is used for supplemental oxygen delivery for clients experiencing breathing difficulties. The non-rebreather mask includes a one-way valve that allows exhaled air to escape, preventing the rebreathing of carbon dioxide. The client inhales oxygenated air from a reservoir bag attached to the mask, providing high-concentration oxygen therapy. A non-rebreather mask can deliver FiO2 levels of up to 90%, making it an effective intervention for clients requiring high oxygen concentrations. Therefore, the statement that 'A non-rebreather can provide an FiO2 of 40%' is correct. Choices B, C, and D are incorrect because clients should breathe through their nose and mouth, the mask offers a reservoir for inhaling oxygen, and the mask should be assessed and potentially replaced if soiled or damaged, not routinely changed every 3 hours.
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 nurse is asked to perform a task that she believes is outside her scope of practice. What is the appropriate response to this issue?
- A. Contact the state board of nursing licensure to report the offense
- B. Review the state scope of practice standards for nurses
- C. Ask another nurse to perform the task to learn the procedure
- D. Contact the house supervisor to make the decision on whether the nurse should perform the task
Correct answer: B
Rationale: When faced with a task that a nurse believes may be beyond their scope of practice, it is essential to refer to the state's specific scope of practice standards for nurses. This step is crucial as these standards can vary between states, providing clarity on what tasks are permissible. By reviewing these standards, the nurse can determine if the task falls within their scope of practice. Contacting the state board of nursing licensure to report the offense (Choice A) is premature and should only be considered if there is a serious violation after reviewing the scope of practice. Asking another nurse to perform the task (Choice C) does not address the issue of clarifying the scope of practice. Contacting the house supervisor (Choice D) may be necessary if the nurse cannot determine the appropriateness of the task based on the scope of practice standards.
5. A nurse is required to float to another unit within the hospital where he is asked to care for a client on a ventilator. The nurse is uncomfortable with this assignment, as he has not had a ventilated client since nursing school. What is the nurse's most appropriate response?
- A. Explain to the nursing supervisor the level of discomfort and ask for a different assignment
- B. State that the client's needs are outside the nurse's scope of practice and request a different assignment
- C. Accept the assignment, asking for help when necessary
- D. Request to return to the home unit and send another nurse who can perform the job
Correct answer: A
Rationale: When floating to another unit and asked to take an assignment that falls outside a nurse's comfort zone, the nurse should notify the area supervisor of the level of discomfort and request a different assignment. Caring for ventilated clients typically falls within the scope of nursing practice; however, discomfort with the situation may not necessarily be overcome by accepting the assignment. Alternatively, the effects could be harmful to the client if the nurse is unfamiliar with this type of care. Requesting a different assignment is the most appropriate response in this situation, ensuring patient safety and the nurse's comfort level. Stating that the client's needs are outside the nurse's scope of practice (Choice B) may not be accurate, as caring for ventilated clients usually falls within the scope of nursing practice. Accepting the assignment (Choice C) without addressing the discomfort may compromise patient safety. Requesting to return to the home unit (Choice D) does not address the immediate need of caring for the ventilated client and may delay appropriate care.
