1. A nurse is reviewing the laboratory results for a client who has end-stage liver disease. Which of the following findings should the nurse expect?
- A. Elevated albumin
- B. Elevated ammonia
- C. Decreased total bilirubin
- D. Decreased prothrombin time
Correct answer: B
Rationale: In end-stage liver disease, the liver's inability to convert ammonia into urea leads to elevated ammonia levels. Elevated ammonia levels can result in hepatic encephalopathy, a serious complication. Therefore, the correct answer is B. Elevated albumin (Choice A) is not typically seen in end-stage liver disease as liver dysfunction often leads to decreased albumin levels. Decreased total bilirubin (Choice C) is unlikely in end-stage liver disease, as bilirubin levels tend to be elevated due to impaired liver function. Decreased prothrombin time (Choice D) is also not expected in end-stage liver disease, as impaired liver function results in prolonged prothrombin time.
2. A client has a new prescription for a low-fat diet. Which of the following foods should be recommended?
- A. Bacon
- B. Whole milk
- C. Chicken breast
- D. Cheese
Correct answer: C
Rationale: When following a low-fat diet, it is essential to choose foods that are low in fat. Chicken breast is a lean protein source that is low in fat, making it a suitable option for a low-fat diet. Bacon, whole milk, and cheese are higher in fat content and should be avoided or limited in a low-fat diet. Bacon is high in saturated fat, whole milk contains significant amounts of fat, including saturated fat, and cheese is also high in fat. Therefore, these options are not ideal for a low-fat diet.
3. What are the key differences between systolic and diastolic heart failure?
- A. Systolic: Reduced ejection fraction; Diastolic: Preserved ejection fraction
- B. Systolic: Preserved ejection fraction; Diastolic: Reduced ejection fraction
- C. Systolic: Right-sided heart failure; Diastolic: Left-sided heart failure
- D. Systolic: Pulmonary congestion; Diastolic: Systemic congestion
Correct answer: A
Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.
4. A client with a history of atrial fibrillation is prescribed dabigatran (Pradaxa). Which instruction should the nurse include in the client's teaching?
- A. Take the medication with food to improve absorption.
- B. Avoid foods high in vitamin K.
- C. Take the medication at the same time each day.
- D. Increase your intake of high-potassium foods.
Correct answer: C
Rationale: The correct instruction for the nurse to include in the client's teaching regarding dabigatran (Pradaxa) is to take the medication at the same time each day. This ensures a consistent blood level and effectiveness of the medication, which is crucial in managing atrial fibrillation and preventing complications. It helps maintain a steady therapeutic effect and reduces the risk of erratic drug levels in the body.
5. What are the risk factors for pressure ulcer development?
- A. Immobility and poor nutrition
- B. Obesity and diabetes
- C. Dehydration and malnutrition
- D. Use of assistive devices and prolonged bedrest
Correct answer: A
Rationale: Corrected Rationale: The correct answer is immobility and poor nutrition. Immobility can lead to constant pressure on certain areas of the body, while poor nutrition can impair tissue repair and regeneration, both contributing to the development of pressure ulcers. Choices B, C, and D are incorrect because while obesity, diabetes, dehydration, malnutrition, use of assistive devices, and prolonged bedrest can impact skin integrity and wound healing, they are not the primary risk factors specifically associated with pressure ulcer development.
