PN Exit Exam 2023 Quizlet
1. Which type of cell is responsible for producing antibodies in the immune system?
- A. B lymphocytes
- B. T lymphocytes
- C. Macrophages
- D. Neutrophils
Correct answer: A
Rationale: The correct answer is A: B lymphocytes. B lymphocytes (B cells) are a crucial part of the adaptive immune system. They produce antibodies, which are proteins that specifically target and neutralize pathogens such as bacteria and viruses. T lymphocytes (choice B) are involved in cell-mediated immunity rather than antibody production. Macrophages (choice C) are phagocytic cells that engulf and digest pathogens but do not produce antibodies. Neutrophils (choice D) are a type of white blood cell that primarily function in the innate immune response by phagocytosing pathogens.
2. 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.
3. The PN is caring for a client with schizophrenia who continues to repeat the last words heard. Which nursing problem should the PN document in the medical record?
- A. Altered thought processes
- B. Impaired social interaction
- C. Risk for self-directed violence
- D. Disturbed thought processes
Correct answer: D
Rationale: The correct answer is D: Disturbed thought processes. Echolalia, the repetition of heard words, is associated with disturbed thought processes, which are commonly seen in schizophrenia. Altered thought processes (Choice A) is a generic term and does not specifically address the behavior of repeating words. Impaired social interaction (Choice B) is not the primary concern when a client repeats the last words heard. Risk for self-directed violence (Choice C) is not directly related to the behavior of repeating words but focuses on the potential harm the client may cause to themselves.
4. The PN and UAP enter a client's room and find the client lying on the bed. The PN determines that the client is unresponsive. Which instruction should the PN give the UAP first?
- A. Obtain emergency help
- B. Feel for a carotid pulse
- C. Bring a glucometer to the room
- D. Check the blood pressure
Correct answer: A
Rationale: The correct answer is to instruct the UAP to obtain emergency help first. When a client is unresponsive, it could indicate a life-threatening condition that requires immediate intervention. Ensuring emergency help is on the way is the priority to address the potentially critical situation. Feeling for a carotid pulse, bringing a glucometer, or checking the blood pressure are important assessments but should come after taking steps to secure immediate assistance.
5. The home health PN suspects elder abuse after observing fresh lacerations on the arms and legs of an older adult male client who lives with his daughter. Which action is most important for the PN to take?
- A. Document the lacerations in the client's record
- B. Report findings to the supervisor for referral to adult protective services
- C. Ask the daughter who has been taking care of the client on a daily basis
- D. Apply dry dressings after cleansing the wounds
Correct answer: B
Rationale: The most important action for the PN to take in this situation is to report the findings to the supervisor for referral to adult protective services. Suspected elder abuse must be reported promptly to ensure the safety and protection of the client. Documenting the lacerations in the client's record is important but not as critical as reporting the suspected abuse. Asking the daughter who is the potential abuser may not yield accurate information and could compromise the safety of the client. Applying dressings to the wounds is a lower priority compared to addressing the suspected elder abuse.
