PN Exit Exam 2023 Quizlet
1. Which neurotransmitter is most closely associated with mood regulation and is targeted by antidepressants?
- A. Serotonin
- B. Dopamine
- C. GABA
- D. Acetylcholine
Correct answer: A
Rationale: The correct answer is A: Serotonin. Serotonin plays a vital role in mood regulation, and its imbalance is often associated with depression. Many antidepressants function by boosting serotonin levels in the brain. Dopamine (Choice B) is more linked to reward and pleasure pathways in the brain, not primarily targeted for mood regulation. GABA (Choice C) is an inhibitory neurotransmitter that helps reduce neuronal excitability, not primarily associated with mood regulation. Acetylcholine (Choice D) is involved in muscle movement and cognitive functions, not the primary target of antidepressants for mood regulation.
2. Which is the most important safety measure when administering a medication through a patient’s central venous catheter (CVC)?
- A. Using a sterile technique
- B. Ensuring correct placement of the CVC
- C. Flushing the CVC with saline after administration
- D. Monitoring for signs of infection
Correct answer: B
Rationale: The most important safety measure when administering a medication through a patient’s central venous catheter (CVC) is ensuring the correct placement of the CVC. This is crucial to prevent complications such as extravasation, infection, or improper drug delivery. While using a sterile technique, flushing the CVC with saline after administration, and monitoring for signs of infection are all important aspects of CVC care, ensuring the correct placement of the catheter takes precedence as it directly impacts patient safety during medication administration.
3. A client post-thoracotomy is complaining of severe pain with deep breathing and coughing. What should the nurse encourage the client to do to manage the pain and prevent respiratory complications?
- A. Hold a pillow against the chest while coughing (splinting).
- B. Take shallow breaths to avoid pain.
- C. Increase the dose of pain medication.
- D. Avoid deep breathing exercises.
Correct answer: A
Rationale: Splinting the chest with a pillow helps manage pain during deep breathing and coughing, which is essential to prevent respiratory complications such as atelectasis or pneumonia after thoracic surgery. Holding a pillow against the chest while coughing (splinting) supports the incision site and reduces the pain associated with deep breathing and coughing. Encouraging shallow breaths (Choice B) can lead to respiratory complications due to inadequate lung expansion. Increasing pain medication (Choice C) should be done based on healthcare provider orders and not solely for this situation. Avoiding deep breathing exercises (Choice D) can worsen respiratory function and increase the risk of complications.
4. The nurse assigns a UAP to assist with the personal care of a client experiencing an acute exacerbation of multiple sclerosis. Which instruction should the nurse provide the UAP?
- A. Assist the client with a hot bath
- B. Encourage self-care but allow rest periods
- C. Face the client directly when speaking
- D. Keep the head of the bed elevated at all times
Correct answer: B
Rationale: The correct instruction for the UAP to provide when assisting a client experiencing an acute exacerbation of multiple sclerosis is to encourage self-care but allow rest periods. Clients with multiple sclerosis often experience fatigue, so promoting self-care activities while ensuring they have adequate rest periods is crucial for symptom management and maintaining independence. Choice A is incorrect as hot baths can potentially exacerbate symptoms in clients with multiple sclerosis. Choice C is unrelated to the client's care needs during an acute exacerbation of multiple sclerosis. Choice D is not a priority instruction in this situation and may not directly impact the client's immediate care needs.
5. Which condition is most commonly associated with a "bull's eye" rash?
- A. Lyme disease
- B. Rocky Mountain spotted fever
- C. Syphilis
- D. Toxoplasmosis
Correct answer: A
Rationale: The correct answer is A: Lyme disease. The "bull's eye" rash, or erythema migrans, is a hallmark of early Lyme disease, caused by the bacterium Borrelia burgdorferi. Choice B, Rocky Mountain spotted fever, presents with a different type of rash. Choice C, Syphilis, typically presents with a painless ulcer and rash but not a "bull's eye" rash. Choice D, Toxoplasmosis, does not typically present with a "bull's eye" rash.
