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. An adolescent female asks the nurse about taking retinoic acid (Accutane). What guidance should be provided by the nurse?
- A. The medication should be used for 10 weeks only.
- B. The medication requires that sexually active females use contraception.
- C. The medication lowers hemoglobin levels very quickly.
- D. The medication has few side effects.
Correct answer: B
Rationale: The correct guidance the nurse should provide is that sexually active females must use contraception while taking Accutane and for 1 month after the 20 weeks it is prescribed. Choice A is incorrect because Accutane is typically taken for a longer duration than 10 weeks. Choice C is incorrect because Accutane does not lower hemoglobin levels quickly. Choice D is incorrect as Accutane is known for having many side effects, including the risk of birth defects.
3. The nurse empties the nasogastric suction collection canister of a client who had a bowel resection the previous day and notes that 1,000 mL of gastric secretions were collected in the last 4 hours. The nurse should assess the client for symptoms of which related problem?
- A. Respiratory acidosis.
- B. Metabolic alkalosis.
- C. Hypoglycemia.
- D. Hyperkalemia.
Correct answer: B
Rationale: The correct answer is B: Metabolic alkalosis. Loss of gastric secretions can lead to metabolic alkalosis due to the loss of hydrochloric acid. This can result in an increase in blood pH levels. Respiratory acidosis (choice A) is caused by retention of carbon dioxide, not related to the loss of gastric secretions. Hypoglycemia (choice C) is a low blood sugar level and is not directly related to the loss of gastric secretions. Hyperkalemia (choice D) is an elevated potassium level in the blood and is not typically associated with the loss of gastric secretions.
4. While assessing a client with degenerative joint disease, the nurse observes Heberden's nodes, large prominences on the client's fingers that are reddened. The client reports that the nodes are painful. Which action should the nurse take?
- A. Review the client's dietary intake of high protein foods
- B. Notify the healthcare provider of the finding immediately
- C. Discuss approaches to chronic pain control with the client
- D. Assess the client's radial pulses and capillary refill time
Correct answer: C
Rationale: Discussing approaches to chronic pain control is the most appropriate action in this situation as it helps the client manage the chronic pain associated with Heberden's nodes. Reviewing the client's dietary intake of high protein foods (Choice A) is not directly related to managing the pain caused by Heberden's nodes. Notifying the healthcare provider immediately (Choice B) may not be necessary unless there are urgent complications. Assessing the client's radial pulses and capillary refill time (Choice D) is important but not the priority in addressing the client's reported pain and the presence of Heberden's nodes.
5. A middle-aged man who has a 35-year smoking history presents to the emergency department confused and short of breath. Before starting oxygen, these baseline arterial blood gases (ABGs) are obtained: pH=7.25, pCO2=50 mmHg, HCO3=30 mEq/L. These findings indicate to the nurse that the client is experiencing which acid-base imbalance?
- A. Metabolic acidosis.
- B. Respiratory acidosis.
- C. Metabolic alkalosis.
- D. Respiratory alkalosis.
Correct answer: B
Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.
