NCLEX RN Practice Questions With Rationale

1. In which of the following examples would informed consent not be required?

A. A patient is apprehensive about an upcoming surgery and chooses not to learn of the risks involved with the procedure.
B. A child is rushed to the Emergency Room after falling from a third-story window.
C. An adult in a coma in a mental health institution with no listed next of kin.
D. Informed consent is not required in any of the above examples.

Correct answer: D

Rationale: In emergency situations where immediate treatment is necessary to prevent further harm or save a life, such as in option B where a child is rushed to the Emergency Room after a fall, informed consent may be waived to provide prompt care. In option A, though the patient is apprehensive about surgery and chooses not to learn the risks, informed consent is not required as it is the patient's right to refuse information. In option C, when an adult is in a coma with no next of kin listed, decisions may be made in the patient's best interest following legal and ethical guidelines. Therefore, informed consent is not needed in any of the scenarios presented.

2. A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?

A. Peaked T waves on the ECG
B. Muscle spasms
C. Constipation
D. A prominent U wave on the ECG

Correct answer: A

Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.

3. Who owns a patient's x-rays?

A. The patient
B. The doctor
C. The facility that performed the procedure
D. None of the above

Correct answer: C

Rationale: X-rays are typically owned by the facility that conducts the procedure, not the patient or the doctor. The facility that performs the procedure is responsible for maintaining and storing the x-rays as part of the patient's medical records. The patient does not own the x-rays since they are part of their medical record and not a physical possession. The doctor also does not own the x-rays as they are generated as a result of the medical procedure conducted at the facility, making choice C the correct answer.

4. Albert is a patient in the hospital who is scheduled for surgery the following morning. After the pre-operative visit from the anesthesia staff member who has obtained surgical consent, Albert asks for an explanation of what type of surgery he is going to have. He states that he's not sure what he just signed. What is your best response?

A. Don't worry, they'll explain it in the operating room.
B. It's standard procedure to get the consent; you don't need to worry.
C. Let me ask the nurse anesthetist to come back and explain it further.
D. Someone will review it with you prior to surgery.

Correct answer: C

Rationale: The correct response is to ensure that the patient fully understands the nature of the surgery they are about to undergo. If the patient expresses uncertainty about the procedure they signed consent for, it indicates a lack of informed consent, which is essential before any surgery. By requesting the nurse anesthetist to return and provide a more detailed explanation, the patient can make an informed decision. Choices A, B, and D do not address the issue of the patient's lack of understanding and the need for informed consent, making them incorrect. Option C is the best course of action to rectify the situation and ensure the patient's understanding and consent are properly obtained.

5. You have noticed that the last several patients you have cared for have had questionable blood pressure readings from their arterial lines. When checked against cuff pressures, a discrepancy has been noted, and further investigation has revealed faulty transducers. This is not the first product issue with this company. What positive step could you take to help resolve this situation?

A. Use the old stock from a previous company
B. Verify the cuff pressures every hour to ensure accuracy
C. Notify the risk manager
D. Form a peer workgroup to evaluate new products

Correct answer: D

Rationale: Forming a peer workgroup to evaluate new products would be an excellent opportunity for collaboration among peers, management, and the purchasing department. When clinicians are engaged to work toward solutions that address patient care issues, they experience more empowerment and control over their work environments. Choice A is incorrect because using old stock from a previous company does not address the root cause of the faulty transducers from the current company. Choice B is incorrect as verifying cuff pressures every hour does not directly address the issue of faulty transducers. Choice C is less effective than forming a peer workgroup as it involves only notifying the risk manager without involving a collaborative effort to resolve the product issue.
