A client learns about pursed-lip breathing. Which statement by the client indicates teaching has been effective?
Correct Answer: B
Rationale: The correct answer is B because pursed-lip breathing involves inhaling slowly through the nose and exhaling slowly through pursed lips, which helps improve lung function and relaxes the client. Choice A is incorrect because breathing in quickly through the mouth is not part of pursed-lip breathing technique. Choice C is incorrect as holding breath before exhaling is not recommended in pursed-lip breathing. Choice D is partially correct but lacks the emphasis on inhaling slowly through the nose. Therefore, the most effective statement indicating correct teaching is choice B.
