Nursing Elites

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 the most common clinical manifestation of coarctation of the aorta?

• A. Clubbing of the digits
• B. Upper extremity hypertension
• C. Pedal edema and portal congestion
• D. Loud systolic ejection murmur

Correct answer: B

Rationale: The correct answer is B: Upper extremity hypertension. Coarctation of the aorta leads to increased blood pressure in the upper extremities. The pressure in the arms is typically 20 mm Hg higher than in the legs. Choice A, clubbing of the digits, is not a common clinical manifestation of coarctation of the aorta. Choice C, pedal edema, and portal congestion are more suggestive of conditions like heart failure rather than coarctation of the aorta. Choice D, loud systolic ejection murmur, can be heard in conditions like aortic stenosis, but it is not the most common clinical manifestation of coarctation of the aorta.

3. A client with rheumatoid arthritis is prescribed methotrexate. Which instruction should the nurse include in the teaching plan?

• A. Avoid taking folic acid supplements
• B. Report any signs of infection immediately
• C. Limit fluid intake to prevent edema
• D. Increase intake of high-calcium foods

Correct answer: B

Rationale: The correct instruction that the nurse should include in the teaching plan for a client prescribed methotrexate is to report any signs of infection immediately. Methotrexate can suppress the immune system, making the individual more susceptible to infections. Reporting signs of infection promptly allows for timely intervention. Choices A, C, and D are incorrect. Avoiding folic acid supplements is not recommended because methotrexate can lead to folate deficiency, so supplementation may be necessary. There is no direct correlation between fluid intake limitation and methotrexate use. Increasing high-calcium foods is not specifically related to methotrexate therapy for rheumatoid arthritis.

4. A client is receiving intravenous potassium chloride for hypokalemia. Which action should the nurse take to prevent complications during the infusion?

• A. Administer the infusion rapidly
• B. Monitor the infusion site for signs of infiltration
• C. Use a syringe pump for the infusion
• D. Flush the IV line with normal saline before starting the infusion

Correct answer: B

Rationale: The correct action to prevent complications during the infusion of potassium chloride is to monitor the infusion site for signs of infiltration. Rapid administration can lead to adverse effects, including cardiac arrhythmias. Using a syringe pump is not typically necessary for this infusion. Flushing the IV line with normal saline is a good practice but not directly related to preventing complications specifically during the infusion of potassium chloride.

5. A client who is receiving general anesthesia begins to demonstrate symptoms of malignant hyperthermia. Which intervention should the perioperative nurse prepare to implement first?

• A. Ensure patency of an indwelling catheter and measure hourly intake and output.
• B. Prepare for cessation of the anesthesia and the surgical procedure.
• C. Obtain specimens of ABGs and serum electrolytes.
• D. Initiate cooling measures using iced normal saline by nasogastric lavage.

Correct answer: B

Rationale: The correct answer is B: Prepare for cessation of the anesthesia and the surgical procedure. Malignant hyperthermia is a severe reaction to certain medications used during general anesthesia. The immediate intervention to manage malignant hyperthermia is to stop the triggering agents, which include anesthesia and surgery. Ensuring patency of an indwelling catheter and measuring intake and output, obtaining specimens of ABGs and serum electrolytes, and initiating cooling measures are important interventions but should follow the immediate action of stopping the anesthesia and surgery to address the life-threatening condition of malignant hyperthermia.
