A nurse is caring for a patient who is post-operative following a knee replacement. The nurse should encourage the patient to perform which of the following exercises to prevent complications?

Correct Answer: A

Rationale: The correct answer is A: Quadriceps setting exercises. These exercises help prevent complications by strengthening the quadriceps muscles, which are crucial for knee stability and joint support post-surgery. They also aid in preventing muscle atrophy and promoting blood circulation. Leg lifts with weights (B) may strain the knee joint, leading to complications. Isometric muscle contractions (C) involve static muscle contractions and do not provide the necessary range of motion needed post-knee surgery. Active range-of-motion exercises (D) may be beneficial but should be performed after quadriceps setting exercises to avoid unnecessary strain on the knee joint.

Correct Answer: C

Rationale: The correct answer is C. This statement indicates a misunderstanding because stopping medication once blood pressure is normal can lead to a relapse of hypertension. Step 1: Medication management is crucial for long-term control of hypertension. Step 2: Stopping medication abruptly can cause blood pressure to rise again. Step 3: Regular monitoring, limiting sodium intake, and exercising are all important aspects of hypertension management. Summary: Choices A, B, and D demonstrate good understanding of hypertension management, while choice C shows a need for further education on the importance of continued medication use.

Correct Answer: A

Rationale: The correct answer is A: Jaundice. In chronic liver disease, impaired liver function can result in the accumulation of bilirubin leading to jaundice. Jaundice is characterized by yellowing of the skin and eyes. Monitoring for jaundice is crucial in assessing the progression of liver disease. B: Hypoglycemia is not a common complication of chronic liver disease. Liver plays a role in glycogen storage and glucose production, so hypoglycemia is less likely. C: Hyperglycemia is more commonly associated with conditions like diabetes rather than chronic liver disease. The liver's role in glucose regulation may be impaired, but hyperglycemia is not a typical complication. D: Anemia is not directly related to liver disease, although it may occur as a secondary complication due to factors like decreased production of certain blood components. Monitoring for anemia is important, but jaundice is a more specific complication of chronic liver disease.

Correct Answer: B

Rationale: The correct answer is B because ethnicity is defined by shared heritage, culture, language, or religion. This definition encompasses the key components that make up an individual's ethnic identity. Choice A is incorrect because while political forces may influence ethnicity, it does not define the concept itself. Choice C is incorrect as ethnicity is not necessarily related to belief in a higher power. Choice D is incorrect as ethnicity is not solely a learned behavior but also includes innate aspects like heritage.
