NCLEX RN Practice Questions With Rationale

1. 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.

2. 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.

3. A patient is being seen in the crisis unit reporting that poison letters are coming in the mail. The patient has no history of psychiatric illness. Which group of the following medications would the patient most likely be started on?

A. Aripiprazole (Abilify)
B. Risperidone (Risperdal Consta)
C. Fluphenazine (Prolixin)
D. Fluoxetine (Prozac)

Correct answer: A

Rationale: In this scenario, where a patient without a history of psychiatric illness is experiencing psychotic symptoms like believing in poison letters, the most suitable medication group to start the patient on would be atypical antipsychotics. Aripiprazole (Abilify) belongs to this group and is preferred due to its efficacy with fewer side effects compared to conventional antipsychotics. Risperidone (Risperdal Consta) is also an atypical antipsychotic but is usually indicated after stabilizing the patient with oral medications. Fluphenazine (Prolixin) is a conventional antipsychotic, which is less favored due to its side effect profile. Fluoxetine (Prozac) is an antidepressant and is not the first-line treatment for psychotic symptoms.

4. Jack is a 2-month-old with a diagnosis of spinal muscular atrophy (SMA) type I. He has been admitted to the hospital for progressive respiratory difficulty. His parents have been informed that if he is not placed on ventilatory support, he will continue to decompensate and die of respiratory failure. Jack's physician discusses the poor prognosis of Jack's condition, and tells the parents that he will not be able to be removed from ventilatory support once it is initiated, due to his progressive neurological disease. After much discussion, the parents have decided to decline ventilatory support, agree to a do not resuscitate (DNR) order, and request hospice care for Jack. Another parent heard them discussing Jack's situation in the waiting room and says she could never do that to her baby. What is the most appropriate response to this parent?

A. You never know what you'll do until you're in that situation.
B. I can't discuss another patient's situation.
C. They have been through too much already.
D. You can contact administration with your concerns.

Correct answer: B

Rationale: In healthcare settings, privacy regulations prevent professionals from discussing patient situations with individuals not involved in that patient's care. Maintaining patient confidentiality is crucial to protect sensitive information. In this scenario, sharing details about Jack's situation with the parent who overheard the conversation would breach confidentiality. It is important to handle such situations delicately, especially in emotional environments like intensive care unit waiting rooms. While empathy and support are essential, it is equally crucial to respect patient privacy and confidentiality. Therefore, responding with 'I can't discuss another patient's situation' is the most appropriate and professional response in this context.

5. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?

A. External light sources may cause falsely high oximetry values
B. A bright light in the client's face may cause a low pulse oximetry
C. External light sources may cause falsely low oximetry values
D. The client needs a dark and quiet room to recover and maintain proper oxygenation

Correct answer: A

Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.
