Correct Answer: D

Rationale: Choice D is the correct answer because a swollen and thickened spermatic cord could indicate testicular torsion, which is a surgical emergency. Testicular torsion occurs when the spermatic cord twists, cutting off the blood supply to the testicle. This condition requires immediate intervention to prevent testicular damage. Choices A, B, and C do not present findings that suggest a surgical emergency requiring immediate intervention.

Correct Answer: A

Rationale: The correct answer is A. Compression stockings should be applied while the client is lying down to prevent pooling of blood in the legs, which can occur when the client is sitting or standing. Choice B is incorrect as inserting two fingers under the proximal end of the stocking helps ensure proper fit. Choice C is incorrect as elevating the feet while lying down is a correct technique for applying compression stockings. Choice D is incorrect as ensuring the toes are warm after putting the stockings on is a good practice for client comfort.

Correct Answer: D

Rationale: The correct answer is D. Under the health services support area concept, medical care under MEDCOM is divided into eight geographical areas of responsibility. Each of these areas is designated as a health services support region, and they are further subdivided into two or more health service areas. Choices A, B, and C are incorrect because they do not accurately describe how the medical care under MEDCOM is divided.

Correct Answer: D

Rationale: The correct answer is D, 'Combat lifesaver.' A Combat Lifesaver is a nonmedical member of a unit who is trained in advanced first aid procedures, providing care beyond basic first aid. Choice A, 'Area support squad leader,' does not specifically refer to someone trained in providing advanced care. Choice B, 'ATLS specialist,' refers to someone trained in Advanced Trauma Life Support (ATLS), which is beyond the scope of the question. Choice C, 'Tactical lifesaver,' is not a recognized term for the role described in the question.

Correct Answer: B

Rationale: The correct answer is B: Pork. Pork is high in thiamine, which is important for preventing thiamine deficiency. Thiamine, also known as vitamin B1, is essential for the proper functioning of the nervous system and metabolism. While fish, beef, and eggs are nutritious foods, they are not as high in thiamine as pork. Fish is more commonly known for its omega-3 fatty acids, beef for its iron content, and eggs for being a good source of protein and other nutrients.
