Correct Answer: C

Rationale: The correct answer is C. Neomycin can interfere with the absorption of fat-soluble vitamins such as vitamins A, D, E, and K. Choice A is incorrect because neomycin does not affect the absorption of iron, copper, and zinc. Choice B is incorrect as neomycin does not impact the absorption of protein and amino acids. Choice D is also incorrect as neomycin does not decrease the absorption of water-soluble vitamins like vitamin C and the B vitamins.

Correct Answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.

Correct Answer: B

Rationale: In patients with heart failure, a low-sodium diet is most recommended. This type of diet helps manage fluid retention by reducing the amount of sodium in the body. Excess sodium can lead to fluid accumulation, putting additional strain on the heart. High-sodium diets can exacerbate symptoms of heart failure by causing fluid retention and increasing blood pressure. High-fat and low-carbohydrate diets are not specifically recommended for heart failure patients and may not address the underlying issues related to fluid balance and heart function.

Correct Answer: A

Rationale: The correct characteristics of anthrax are that cutaneous anthrax causes black eschar lesions, and flu-like symptoms are typical of pulmonary anthrax. Choice B is incorrect because it only includes information about cutaneous anthrax lesions but doesn't cover the flu-like symptoms of pulmonary anthrax. Choice C is incorrect as gastrointestinal anthrax does not cause 'blood anthrax,' it causes symptoms like severe abdominal pain, vomiting, and diarrhea. Choice D is incorrect as flu-like symptoms are associated with pulmonary anthrax, not with gastrointestinal anthrax.

Correct Answer: D

Rationale: The lithotomy position is the most suitable position for procedures involving vaginal and cervical examination because it provides the best access to the vaginal and cervical regions. In this position, the patient lies on their back with their legs flexed and feet placed in stirrups, allowing for optimal visualization and access to the area. This position facilitates proper examination, diagnosis, and treatment when working in the gynecological field. Choices A, B, and C are incorrect as they do not provide the necessary exposure and access required for a thorough vaginal and cervical examination. Dorsal recumbent, side lying, and supine positions may limit visibility and hinder the examination process in such cases.
