Which patient statement about tuberculosis treatment indicates a need for further teaching?

Correct Answer: B

Rationale: The correct answer is B. The patient should continue wearing a mask until the treatment is completed to prevent the spread of tuberculosis. Stopping the mask before completing treatment can lead to transmission of the disease. Choices A, C, and D are correct statements that show understanding of tuberculosis treatment and monitoring.

Correct Answer: C

Rationale: The correct answer is C because rifampin can decrease the effectiveness of hormonal birth control methods. The nurse should educate the patient on the importance of using non-hormonal birth control methods while taking rifampin to prevent unintended pregnancy. A) Reporting orange discoloration of urine is a common side effect of rifampin and does not require immediate medical attention. B) Taking rifampin with food can help reduce gastrointestinal upset but is not the most crucial information to convey. D) Stopping medication once symptoms improve can lead to treatment failure and drug resistance. It is important to complete the full course of antibiotics for tuberculosis treatment.

Correct Answer: B

Rationale: The correct answer is B: Reassure the patient this is a normal side effect. Rifampin commonly causes orange discoloration of urine, known as rifampin-induced discoloration. This is a harmless and expected side effect due to the drug's mechanism of action. Discontinuing the medication immediately (A) is unnecessary as it does not pose a serious risk. Notifying the healthcare provider immediately (C) is not required for this benign side effect. Assessing for signs of hepatotoxicity (D) is not relevant to the orange discoloration of urine.

Correct Answer: B

Rationale: The correct answer is B: Do not smoke while using oxygen. Smoking near oxygen can lead to a fire hazard due to the highly flammable nature of oxygen. Smoking should be strictly avoided to prevent any potential accidents. A: Using oxygen continuously is essential for COPD patients, but the priority is to prevent fire hazards by not smoking while using oxygen. C: Increasing the flow rate without healthcare provider guidance can be dangerous and may not address the underlying cause of shortness of breath. D: Removing oxygen during meals is unnecessary and can compromise oxygen delivery, which is crucial for COPD patients.

Correct Answer: D

Rationale: The correct answer is D because puffing the cheeks while exhaling through pursed lips is not a correct technique for pursed-lip breathing. Pursed-lip breathing involves inhaling through the nose and exhaling slowly through pursed lips, which helps improve breathing efficiency. Option A correctly describes the inhalation and exhalation process. Option B correctly mentions the recommended exhalation duration. Option C correctly suggests practicing pursed-lip breathing during activities.
