Correct Answer: A

Rationale: Hepatic encephalopathy is caused by the buildup of ammonia in the body. Ammonia, a byproduct of protein metabolism, normally gets converted to urea in the liver for excretion. However, in liver dysfunction, such as cirrhosis, the liver cannot effectively convert ammonia to urea, leading to its accumulation in the body and subsequently causing hepatic encephalopathy. Choices B, C, and D are incorrect as they do not directly relate to the pathophysiology of hepatic encephalopathy.

Correct Answer: D

Rationale: Corrected Rationale: Patients on long-term steroid therapy should be monitored for osteoporosis due to the medication's potential to decrease bone density. Choices A, B, and C are incorrect. While long-term steroid therapy can also lead to hyperglycemia, hypothyroidism, and hypertension, the primary concern and most common risk associated with prolonged steroid use is osteoporosis.

Correct Answer: B

Rationale: The correct answer is B: "Have you had any unexplained weight loss?" Unexplained weight loss can be a common symptom of various endocrine disorders, such as hyperthyroidism and diabetes. This weight loss is often despite an adequate or increased appetite. Choices A, C, and D are less likely to be directly associated with endocrine dysfunction. Pain in the legs when walking could be related to musculoskeletal issues, changes in bowel movements may suggest gastrointestinal concerns, and joint pain is more commonly linked to rheumatologic conditions rather than primary endocrine disorders.

Correct Answer: B

Rationale: The correct answer is B: Vitamin K. Warfarin works by inhibiting the action of vitamin K, which is crucial for the synthesis of clotting factors in the blood. By interfering with vitamin K, warfarin decreases the production of these clotting factors, thereby prolonging the time it takes for blood to clot. This is why individuals on warfarin therapy need to monitor their vitamin K intake. Choices A, C, and D are incorrect because warfarin does not directly interfere with platelets, calcium, or vitamin B12.

Correct Answer: D

Rationale: The automated data processing systems in the medical C4I headquarters play a crucial role in maintaining patient accountability by tracking patient movement and aiding in the management of health service logistics systems. Therefore, the correct answer is D. Option A is incorrect because the systems do more than just maintaining patient accountability. Option B is incorrect as it focuses solely on tracking patient movement, missing the broader scope. Option C is also incorrect as it only addresses the management of health service logistics systems and overlooks the other functionalities provided by the systems.
