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: 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: 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: A

Rationale: Yes, M6 practical nurses are utilized in field units with patient holding capabilities. These nurses play a crucial role in providing care and support in various healthcare settings. Given this context, the correct answer is 'Yes.' Choice B, 'No,' is incorrect because M6 practical nurses can indeed work in field units with patient holding capabilities, as stated in the extract. Choices C and D are not applicable in this question.

Correct Answer: A

Rationale: The position that best shows chest expansion as well as its movements is when the client is sitting. When the client is seated, their chest is in an optimal position for observing the full range of chest expansion during breathing. This position allows for easy visualization of chest movements and expansion as the client breathes in and out, providing a comprehensive assessment of respiratory function. Choice B (Prone) and Choice D (Supine) involve positions where the chest's movements and expansion are less visible and may not provide an accurate representation of respiratory function. Choice C (Sidelying) can also limit the visibility of chest expansion compared to the sitting position.
