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. Which assessment finding would most likely indicate a complication of enteral tube feeding?
- A. Abdominal distension
- B. Weight gain
- C. Decreased bowel sounds
- D. Diarrhea
Correct answer: A
Rationale: Abdominal distension in a patient receiving enteral tube feeding may indicate a complication such as intolerance to feeding, delayed gastric emptying, or obstruction. Abdominal distension is a common sign of gastrointestinal issues related to enteral tube feeding. Weight gain is typically an expected outcome if the patient is receiving adequate nutrition. Decreased bowel sounds may indicate decreased motility but are not specific to enteral tube feeding complications. Diarrhea can occur due to various reasons, including infections, medications, or dietary changes, but it is not the most likely indication of a complication in enteral tube feeding.
3. When caring for a client with colostomy, which topical skin preparation should the PN apply around the stoma?
- A. Antiseptic cream
- B. Petroleum jelly
- C. Cornstarch
- D. Stomadhesive
Correct answer: D
Rationale: The correct answer is 'Stomadhesive.' Stomadhesive is a protective barrier used around the stoma to prevent skin irritation and to secure the colostomy bag. This preparation helps to maintain skin integrity and prevent complications such as skin breakdown. Antiseptic cream (Choice A) is not typically used around the stoma as it can irritate the skin. Petroleum jelly (Choice B) is also not recommended as it can interfere with the adhesive properties of the colostomy appliance. Cornstarch (Choice C) is not suitable for application around the stoma as it can promote moisture and lead to skin irritation.
4. A client post-splenectomy is at risk for infection. What is the most important preventive measure the nurse should emphasize during discharge teaching?
- A. Take all prescribed antibiotics as directed.
- B. Avoid crowded places and people who are sick.
- C. Wash hands frequently and practice good hygiene.
- D. Keep the surgical site clean and dry.
Correct answer: C
Rationale: The correct answer is C: 'Wash hands frequently and practice good hygiene.' After a splenectomy, the client is at an increased risk of infection due to the role of the spleen in the immune system. Maintaining good hand hygiene, such as frequent handwashing, is crucial to prevent infections. While taking prescribed antibiotics as directed (Choice A) is important if prescribed, it is not the most crucial preventive measure in this scenario. Avoiding crowded places and sick people (Choice B) can help reduce the risk of exposure to pathogens but may not always be feasible. Keeping the surgical site clean and dry (Choice D) is important for wound care but is not the primary preventive measure to protect against infections in a post-splenectomy client.
5. All of the following are posture and body alignment problems EXCEPT:
- A. Kyphosis
- B. Scoliosis
- C. Thrombosis
- D. Lumbar lordosis
Correct answer: C
Rationale: Thrombosis is a condition involving blood clots and is not related to posture or body alignment, unlike kyphosis, scoliosis, and lumbar lordosis, which are spinal alignment issues. Kyphosis refers to excessive outward curvature of the spine, scoliosis is characterized by a sideways curvature of the spine, and lumbar lordosis involves an exaggerated inward curve in the lower back. Thrombosis, on the other hand, is a condition where blood clots form in the blood vessels, not a posture or body alignment problem.
