Which dietary instruction is most important for a client with renal disease?
- A. Avoid all protein-rich foods.
- B. Limit fluid intake to 1500 ml/day.
- C. Increase potassium intake to prevent weakness.
- D. Eat small, frequent meals high in carbohydrates.
Correct Answer: B
Rationale: The most important dietary instruction for a client with renal disease is to limit fluid intake to 1500 ml/day. This is essential to prevent fluid overload, manage electrolyte balance, and reduce strain on the kidneys. Choice A is incorrect because while protein restriction may be necessary in some cases, avoiding all protein-rich foods is not recommended as some protein intake is essential for overall health. Choice C is incorrect because increasing potassium intake is generally not advised for clients with renal disease, as they often need to limit potassium intake. Choice D is also incorrect because while consuming small, frequent meals may be helpful, emphasizing a diet high in carbohydrates is not typically the primary focus for clients with renal disease.

What pathophysiological events occur sequentially in the development of atherosclerosis?
- A. Foam cells release growth factors.
- B. Smooth muscle grows over fatty streaks creating fibrous plaques.
- C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
- D. Arterial endothelium injury causes inflammation.
Correct Answer: D
Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.
After receiving hemodialysis, what is the nurse's priority assessment for a client with chronic kidney disease?
- A. Monitor the client's potassium level.
- B. Assess the client's blood pressure.
- C. Check the client's hemoglobin and hematocrit levels.
- D. Monitor for signs of infection.
Correct Answer: A
Rationale: The correct answer is to monitor the client's potassium level. During hemodialysis, there is a risk of potassium shifting, which can lead to life-threatening arrhythmias if not properly managed. Assessing the potassium level is crucial to prevent complications. While assessing blood pressure, checking hemoglobin and hematocrit levels, and monitoring for signs of infection are important aspects of care for a client with chronic kidney disease, monitoring potassium levels takes precedence due to its immediate life-threatening potential post-dialysis.
A client with osteoarthritis is prescribed acetaminophen. What is the most important teaching the nurse should provide?
- A. Take the medication with food to improve absorption.
- B. Avoid taking other pain medications to prevent liver damage.
- C. Take acetaminophen on an empty stomach to prevent stomach upset.
- D. Monitor liver function tests regularly to detect any liver damage.
Correct Answer: B
Rationale: The correct answer is B. Acetaminophen can cause liver damage if taken in excessive amounts or in combination with other medications containing acetaminophen. Clients should be advised to avoid other pain medications to prevent liver toxicity. Choice A is incorrect because acetaminophen is usually taken with or without food, not specifically on an empty stomach. Choice C is incorrect because taking acetaminophen with food can help prevent stomach upset. Choice D is incorrect because while monitoring liver function tests is important for long-term acetaminophen use, the most crucial teaching is to avoid other pain medications to prevent liver damage.
A client with deep vein thrombosis (DVT) is prescribed heparin therapy. What laboratory value should the nurse monitor?
- A. Monitor the client's liver function tests.
- B. Monitor the client's prothrombin time (PT).
- C. Monitor the client's partial thromboplastin time (PTT).
- D. Monitor the client's red blood cell count.
Correct Answer: C
Rationale: The correct answer is C: Monitor the client's partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.
The nurse is caring for a client who is post-op after a hip replacement. Which of the following nursing actions is most appropriate to prevent dislocation of the hip?
- A. Place an abduction pillow between the client's legs.
- B. Use an abduction pillow between the client's legs.
- C. Encourage the client to cross their legs while sitting.
- D. Encourage the client to sit upright for long periods.
Correct Answer: B
Rationale: Using an abduction pillow between the client's legs is the most appropriate nursing action to prevent dislocation after hip replacement surgery. An abduction pillow helps maintain proper alignment and prevents the hip from dislocating. Placing the client in a high Fowler's position (Choice A) or encouraging them to sit upright for long periods (Choice D) may not provide the necessary support and stability needed to prevent hip dislocation. Encouraging the client to cross their legs while sitting (Choice C) can increase the risk of hip dislocation and should be avoided.
