Correct Answer: D

Rationale: The correct answer is D: Clubbing of the nails. Clubbing is a physical finding associated with chronic respiratory conditions like emphysema and bronchitis. It is characterized by the softening of the nail bed and the loss of the normal angle between the nail and the nail bed. This occurs due to chronic hypoxia and can be a sign of advanced lung disease. Anasarca (choice A) is generalized edema, not specific to respiratory conditions. Scleroderma (choice B) is a connective tissue disorder affecting the skin and other organs, not directly related to respiratory conditions. Pedal erythema (choice C) refers to redness of the feet and is not a typical finding in emphysema or bronchitis.

Correct Answer: D

Rationale: The correct answer is D: Increasing caffeine consumption. Caffeine can potentially raise blood pressure in individuals with hypertension. The rationale is that caffeine is a stimulant that can lead to temporary spikes in blood pressure. This can be harmful for patients with a history of hypertension as it can exacerbate their condition. A: Increasing potassium intake is generally recommended for individuals with hypertension as it can help lower blood pressure. B: Consuming more fruits and vegetables is also beneficial for hypertension due to their high fiber and nutrient content. C: Limiting sodium intake is crucial for managing hypertension as high sodium levels can lead to increased blood pressure. In summary, increasing caffeine consumption is the correct answer to avoid for patients with hypertension, as it can potentially worsen their condition by raising blood pressure.

Correct Answer: B

Rationale: The correct answer is B because stopping insulin when blood sugar is normal can lead to hyperglycemia. A: Monitoring blood sugar is essential for diabetes management. C: Eating balanced diet and exercising help control blood sugar levels. D: Avoiding sugary foods is important to manage blood sugar.

Correct Answer: A

Rationale: The correct answer is A. Encouraging early ambulation and use of compression stockings is crucial post-abdominal surgery to prevent complications like deep vein thrombosis and pneumonia. Ambulation helps prevent blood clots and promotes lung expansion. Compression stockings aid in preventing blood pooling in the legs. Administering pain medication regularly (B) is important but not the priority. Monitoring for infection (C) is essential but not the priority immediately post-op. Providing nutritional support and hydration (D) is important but not as critical as preventing immediate complications.

Correct Answer: C

Rationale: The correct answer is C: mental health issues. When taking a family history, mental health issues are important as they can have a genetic component and can impact the patient's overall health. Emphysema (A) is a respiratory condition, head trauma (B) is not typically hereditary, and fractured bones (D) are usually due to accidents or osteoporosis, not genetic.
