1. Which disorder is characterized by demyelination of neurons in the central nervous system?

• A. Multiple sclerosis
• B. Parkinson's disease
• C. Alzheimer's disease
• D. Huntington's disease

Correct answer: A

Rationale: Multiple sclerosis is the correct answer. It is an autoimmune disease that specifically targets and damages the myelin sheath surrounding neurons in the central nervous system. This demyelination disrupts the transmission of nerve signals and leads to a variety of neurological symptoms. Parkinson's disease (Choice B), Alzheimer's disease (Choice C), and Huntington's disease (Choice D) are neurodegenerative disorders that do not primarily involve demyelination of neurons in the CNS. Parkinson's disease is characterized by the loss of dopamine-producing neurons, Alzheimer's disease by the formation of plaques and tangles in the brain, and Huntington's disease by a genetic mutation affecting nerve cells.

2. At the first dressing change, the PN tells the client that her mastectomy incision is healing well, but the client refuses to look at the incision and refuses to talk about it. Which response by the PN to the client's silence is best?

• A. You will feel better when you see that the incision is not as bad as you may think.
• B. It's OK if you don't want to look or talk about the mastectomy. I will be available when you're ready.
• C. Part of recovery is accepting your new body image, and you will need to look at your incision.
• D. Would you like me to call another nurse to be here while I show you the wound?

Correct answer: B

Rationale: Acknowledging the client's feelings and providing emotional support without pressuring them to look at the incision is important. Choice B is the best response as it respects the client's emotional readiness to confront their body image changes. The client's autonomy and emotional needs are prioritized in this response. Choice A may invalidate the client's feelings by assuming the incision is not as bad as they think, potentially dismissing their emotions. Choice C is insensitive as it imposes a particular view of recovery on the client, disregarding their current emotional state. Choice D may escalate the situation by suggesting the need for another nurse, which could make the client feel uncomfortable and pressured.

3. What is the primary role of the sinoatrial (SA) node in the heart?

• A. Pacemaker of the heart
• B. Blood pressure regulation
• C. Electrical conduction delay
• D. Stimulating muscle contraction

Correct answer: A

Rationale: The correct answer is A: Pacemaker of the heart. The SA node, known as the natural pacemaker, initiates the electrical impulses that set the rhythm for the heartbeat. It is responsible for coordinating the heart's contractions by generating electrical signals at regular intervals. Choice B is incorrect as the SA node's primary function is not related to blood pressure regulation. Choice C is incorrect as the SA node does not cause electrical conduction delay but rather initiates and conducts the electrical impulses. Choice D is incorrect as the SA node does not directly stimulate muscle contraction but rather initiates the electrical events that lead to muscle contraction.

4. A female Native American client who is receiving chemotherapy places a native artifact, an Indian medicine wheel, in her hospital room. The HCP removes the medicine wheel and tells the client, 'This type of thing does not belong in the hospital.' Which intervention should the PN implement?

• A. Teach the client about the importance of adhering to the chemotherapy regimen
• B. Act as the client's advocate when addressing the issue with the HCP
• C. Consult with a Native American healer about the appropriate use of a medicine wheel
• D. Inform the HCP about the client's feelings of culture shock

Correct answer: B

Rationale: Acting as the client's advocate is the most appropriate intervention in this situation. Removing a culturally significant artifact without considering the client's beliefs and emotional needs can be distressing. By advocating for the client, the PN can ensure that the client's cultural practices are respected, which is crucial for her emotional and spiritual well-being during treatment. Choice A is incorrect because while chemotherapy adherence is important, it is not the most immediate concern in this scenario. The client's cultural needs and well-being take precedence. Choice C is incorrect because consulting with a Native American healer might not be necessary at this point and could delay addressing the immediate issue of advocating for the client's rights. Choice D is incorrect because simply reporting the client's feelings of culture shock to the HCP does not actively address the situation or advocate for the client's rights and cultural needs.

5. A client is admitted to the postoperative surgical unit with two test tubes after a left lobectomy. The nurse observed that the chambers are set at the prescribed suction of 20 cm water pressure, and tidying occurs with respirations and bubbling. What action should the nurse implement?

• A. Clamp the chest tube to see if the bubbling activity stops
• B. Notify the registered nurse of the observed bubbling
• C. Maintain system integrity to promote lung reexpansion
• D. Apply an occlusive dressing to the chest

Correct answer: C

Rationale: Maintaining system integrity is essential to promote lung reexpansion in postoperative patients with chest tubes. Clamping the chest tube abruptly can lead to tension pneumothorax, a life-threatening condition. The bubbling observed is a normal sign indicating that the system is functioning correctly, as it allows the drainage of air or fluid from the pleural space. Notifying the registered nurse may be necessary if there are significant concerns or changes observed, but the immediate action should be to ensure system integrity and lung reexpansion.
