Correct Answer: A

Rationale: The correct answer is A: 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, is incorrect as lying face down would not provide a clear view of chest expansion. Choice C, Sidelying, is also incorrect as this position may limit the visibility of chest movements. Choice D, Supine, is not the best position for assessing chest expansion as it may not offer a clear observation of chest movements during breathing.

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. Avoiding irritants like spicy foods, tobacco, and alcohol is crucial in managing mouth ulcers as they can further irritate and worsen the condition. Choice A is incorrect as using a soft-bristle toothbrush may still cause discomfort. Choice B is incorrect as alcohol-containing mouthwashes can be irritating. Choice C is incorrect as swallowing antifungal solution meant for topical use is not appropriate and can be harmful.

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.
