NCLEX RN Practice Questions With Rationale

1. After a lengthy explanation of a medical procedure, the patient asks many questions. The physician answers all of the questions to the best of their ability. The patient then gives consent for treatment. The costly equipment and supplies are put into place, and the patient is prepared. Two minutes before the procedure is to start, the patient begins panicking and changes their mind. Which of the following situations would be the best way to avoid litigation?

A. Document that the patient originally gave consent and proceed if the benefits of the procedure outweigh the patient's wishes.
B. Have the patient sign a form stating that they are refusing consent. If they refuse to sign, do not proceed with the procedure.
C. Repeat the explanation of the procedure until the patient understands that having the procedure done is the best form of treatment. Do not proceed with the procedure.
D. Do not proceed. Document the patient's refusal, have the patient sign a refusal to consent to treatment. If the patient refuses to sign the form, have a witness available to sign.

Correct answer: D

Rationale: In this scenario, the best course of action to avoid litigation is to respect the patient's right to refuse treatment, especially when changing their mind before the procedure starts. By not proceeding with the treatment, documenting the patient's refusal, and having the patient sign a refusal to consent form, you are following proper ethical and legal procedures. If the patient refuses to sign the form, having a witness available to sign further strengthens the documentation of the patient's decision. This approach ensures that the patient's autonomy and right to make informed decisions about their healthcare are respected. Choices A, B, and C do not prioritize the patient's right to refuse treatment and could potentially lead to legal issues if treatment is carried out against the patient's wishes.

2. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?

A. Uncompensated respiratory acidosis
B. Compensated respiratory alkalosis
C. Uncompensated metabolic acidosis
D. Compensated metabolic alkalosis

Correct answer: A

Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.

3. The charge nurse is notified that the unit will be receiving an admission of a client from another bed in the hospital in order to make room for others being admitted through the emergency room. The unit is the Women's Health Center of the hospital. Which of the following patients would be most appropriate to be transferred to this unit?

A. A 26-year-old woman who had a bowel resection
B. A 40-year-old man who underwent a hernia repair
C. A 31-year-old woman with septicemia and who is on a ventilator
D. A 91-year-old man with Alzheimer's disease recovering from a fall

Correct answer: A

Rationale: When deciding on transferring patients between units in a hospital, it is essential to consider the appropriateness of the patient for the receiving unit. The Women's Health Center typically caters to female patients with gynecological or obstetric conditions that do not require intensive monitoring or specialized care. In this scenario, the most suitable patient for transfer to the Women's Health Center would be the 26-year-old woman who had a bowel resection, as her condition aligns more closely with the services provided in that unit. The other options, including a male patient, a critically ill patient on a ventilator, and an elderly patient with Alzheimer's disease, would not be appropriate for transfer to a Women's Health Center due to the specialized care they require, which may not align with the unit's focus and staffing capabilities.

4. Which of the following is an example of libel?

A. A client overhears a nurse telling her assistant that he is 'too high maintenance.'
B. A client reads disparaging remarks that a nurse has written about him in his chart.
C. A nurse fails to notify a physician when a client's hemoglobin level is 8.1 gm/dL.
D. A nurse administers narcotic pain medication to a client in pain but does not have an order.

Correct answer: B

Rationale: Libel involves making defamatory statements against another person in written form. These statements can harm the person's reputation or feelings. In this scenario, the correct answer is when a client reads disparaging remarks that a nurse has written about him in his chart. This constitutes libel because the negative remarks are written down and can potentially damage the client's reputation. Choices A, C, and D do not involve libel. Choice A describes a verbal statement, not written, so it does not constitute libel. Choice C involves a failure to notify a physician, which is a different issue unrelated to libel. Choice D pertains to administering medication without an order, which is a matter of improper practice rather than libel.

5. 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.
