1. A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?
- A. Inflammation of the synovial membrane.
- B. Degeneration of the cartilage in the joint.
- C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
- D. Formation of uric acid crystals in the joint space.
Correct answer: C
Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.
2. What is a causative factor of Hirschsprung disease?
- A. Frequent evacuation of solids, liquid, and gases
- B. Excessive peristaltic movement
- C. The absence of parasympathetic ganglion cells in a portion of the colon
- D. One portion of the bowel telescoping into another
Correct answer: C
Rationale: The correct answer is C: The absence of parasympathetic ganglion cells in a portion of the colon is a causative factor of Hirschsprung disease. This absence leads to the inability of the affected segment of the colon to relax, causing a functional obstruction. Choices A, B, and D are incorrect. Frequent evacuation of solids, liquid, and gases, excessive peristaltic movement, and one portion of the bowel telescoping into another are not causative factors of Hirschsprung disease.
3. Following surgical repair of the bladder, a female client is being discharged from the hospital to home with an indwelling urinary catheter. Which instruction is most important for the nurse to provide to this client?
- A. Avoid coiling the tubing and keep it free of kinks.
- B. Cleanse the perineal area with soap and water twice daily.
- C. Keep the drainage bag lower than the level of the bladder.
- D. Drink 1,000 ml of fluids daily to irrigate the catheter.
Correct answer: C
Rationale: The most crucial instruction for a client with an indwelling urinary catheter post-bladder surgery is to keep the drainage bag positioned lower than the level of the bladder. This positioning prevents backflow of urine into the bladder, reducing the risk of infection. Choice A, avoiding coiling the tubing and keeping it free of kinks, is important to maintain proper flow but not as critical as ensuring the drainage bag is lower than the bladder. Choice B, cleansing the perineal area, is essential for overall hygiene but not directly related to catheter care instructions. Choice D, drinking fluids to irrigate the catheter, is not recommended as it may increase the risk of infection and should be guided by healthcare providers based on specific needs.
4. The nurse is caring for a child who has been diagnosed with attention deficit hyperactivity disorder (ADHD). What is the most important intervention for the nurse?
- A. Help the child enroll in a special education class.
- B. Allay any feelings of guilt the parents may have.
- C. Explain to the parents that medications are lifelong.
- D. Teach the parents how to set limits.
Correct answer: B
Rationale: The most important intervention for the nurse in caring for a child with ADHD is to allay any feelings of guilt the parents may have. Parents of children with ADHD often experience guilt or self-blame, thinking they are responsible for their child's condition. By addressing and alleviating these feelings, the nurse can support the parents in a crucial way. Choice A is not the most important intervention because enrolling the child in a special education class might be a consideration but does not address the emotional needs of the parents. Choice C is incorrect because stating that medications are lifelong may cause unnecessary distress to the parents. Choice D is also not the most important intervention as setting limits is important but not as critical as addressing parental guilt and emotions.
5. The family of a newly admitted child with cystic fibrosis is educated by the nurse that the treatment will be centered on what therapy?
- A. Chest physiotherapy
- B. Mucus-drying agents
- C. Prevention of diarrhea
- D. Insulin therapy
Correct answer: A
Rationale: The correct answer is A: Chest physiotherapy. In cystic fibrosis, chest physiotherapy and aerosol medications are fundamental components of treatment to help clear mucus from the lungs, reduce the risk of infections, and improve breathing. Mucus-drying agents (Choice B) are not typically used in the treatment of cystic fibrosis. Prevention of diarrhea (Choice C) is not a primary focus in the treatment of cystic fibrosis. Insulin therapy (Choice D) is not relevant to cystic fibrosis, as it is a treatment for diabetes.
