Correct Answer: C

Rationale: The correct answer is C. Limiting intake of beef to 4 ounces per week is an effective dietary modification to manage high cholesterol. Choice A is incorrect because the frequency and duration of exercise alone may not be sufficient to lower cholesterol significantly. Choice B is incorrect as proteins, including lean sources like poultry and fish, can be a part of a healthy diet. Choice D is incorrect as low-density lipoproteins, known as bad cholesterol, should be decreased, not increased, for heart health.

Correct Answer: B

Rationale: The correct answer is 'Blended.' This family is considered a blended family because it consists of children from previous marriages, along with the biological child of the current marriage. Choice A ('Extended') refers to a family that includes relatives beyond the nuclear family, such as grandparents or aunts/uncles. Choice C ('Nuclear') typically consists of a husband, wife, and their biological children only. Choice D ('Alternative') does not accurately describe the family structure presented in the scenario.

Correct Answer: B

Rationale: A new or changed heart murmur is a common sign of valve involvement in infective endocarditis, indicating a complication such as valve damage or regurgitation. Dyspnea is more commonly associated with respiratory or cardiac conditions not directly related to infective endocarditis. A macular rash is not a typical symptom of infective endocarditis, suggesting other conditions like infectious diseases. Hemorrhage is not a direct complication of infective endocarditis but may occur due to factors such as anticoagulant therapy or underlying bleeding disorders.

Correct Answer: A

Rationale: The correct answer is to infuse hypotonic IV fluids. In hypernatremia, there is an elevated sodium concentration in the blood, and diluting it with hypotonic fluids helps to lower the sodium levels. Implementing a fluid restriction or increasing sodium intake would worsen hypernatremia by further concentrating sodium in the body. Administering sodium polystyrene sulfonate is used for treating hyperkalemia, not hypernatremia.

Correct Answer: B

Rationale: Using pillows to keep the client's extremities in a functional position is crucial in preventing joint contractures. This intervention helps maintain proper alignment of the joints and reduces the risk of contractures by preventing prolonged positioning that can lead to muscle shortening. Encouraging the client to perform active range-of-motion exercises (Choice A) is beneficial for maintaining mobility but may not be the most important intervention to prevent joint contractures. Placing the client in a prone position for 30 minutes each day (Choice C) can be helpful for preventing pressure ulcers but is not directly related to preventing joint contractures. Performing passive range-of-motion exercises on the affected side (Choice D) can aid in maintaining joint flexibility but may not be as crucial as using pillows to prevent joint contractures.
