Pathophysiology Practice Questions
1. What is a cause of the crystallization within the synovial fluid of the joint affected by gouty arthritis?
- A. Destruction of proteoglycans
- B. Underexcretion of uric acid
- C. Overexcretion of uric acid
- D. Increased absorption of uric acid
Correct answer: B
Rationale: The correct answer is B: Underexcretion of uric acid. Gouty arthritis is primarily caused by the underexcretion of uric acid, leading to its accumulation in joints and subsequent crystallization. Choices A, C, and D are incorrect as they do not directly relate to the pathophysiology of gout. Destruction of proteoglycans, overexcretion of uric acid, and increased absorption of uric acid are not primary causes of gouty arthritis.
2. A student is feeling inside her backpack to find her mobile phone. There are a number of other items in the bag other than the phone. The nurse knows that which term best describes one's ability to sense the shape and size of an object in the absence of visualization?
- A. Stereognosis
- B. Graphesthesia
- C. Proprioception
- D. Kinesthesia
Correct answer: A
Rationale: Stereognosis is the correct answer. It refers to the ability to recognize objects by touch, specifically determining their shape and size without relying on visual cues. Graphesthesia, on the other hand, is the ability to recognize symbols or numbers traced on the skin. Proprioception involves the awareness of body position and movement. Kinesthesia relates to the perception of body movement.
3. Which of the following statements indicates more teaching is needed regarding secondary lymph organs? ________is/are a secondary lymph organ.
- A. The spleen
- B. Peyer's patches
- C. Adenoids
- D. The liver
Correct answer: D
Rationale: The correct answer is D, 'The liver.' The liver is not a secondary lymph organ. Secondary lymph organs are primarily involved in the immune response, such as the spleen, Peyer's patches, and adenoids. The spleen filters blood and is essential for immune function. Peyer's patches are located in the small intestine and help protect against pathogens. Adenoids are located in the throat and play a role in immune defense. Therefore, the liver is the incorrect choice as it is not part of the secondary lymph organ system.
4. What is a cause of the crystallization within the synovial fluid of the joint affected by gouty arthritis?
- A. Destruction of proteoglycans
- B. Underexcretion of uric acid
- C. Overexcretion of uric acid
- D. Increased absorption of uric acid
Correct answer: B
Rationale: The correct answer is B: Underexcretion of uric acid. In gouty arthritis, the crystallization within the synovial fluid of the affected joint is caused by the underexcretion of uric acid, leading to the accumulation and subsequent crystallization of urate crystals. Choice A, destruction of proteoglycans, is incorrect as it is not directly related to the crystallization process in gouty arthritis. Choice C, overexcretion of uric acid, is incorrect because gout is primarily associated with underexcretion or decreased excretion of uric acid rather than overexcretion. Choice D, increased absorption of uric acid, is also incorrect as the primary issue in gouty arthritis is the body's inability to properly eliminate uric acid.
5. A 60-year-old man presents with painless hematuria. Which of the following should be the next step in the evaluation?
- A. Urinalysis
- B. Renal ultrasound
- C. Cystoscopy
- D. Intravenous pyelogram
Correct answer: C
Rationale: In a 60-year-old man presenting with painless hematuria, the next step in the evaluation should be cystoscopy. Cystoscopy is recommended to assess the cause of hematuria, particularly to rule out bladder cancer, which is more common in older individuals. Urinalysis (Choice A) can provide initial information but may not definitively diagnose the underlying cause. Renal ultrasound (Choice B) and intravenous pyelogram (Choice D) are imaging studies that may be considered later in the evaluation process but are not the initial step for painless hematuria.
