Which patient statement indicates a need for additional teaching about oxygen therapy?

Correct Answer: B

Rationale: The correct answer is B because increasing oxygen flow rate without healthcare provider approval can be dangerous, leading to oxygen toxicity. Choice A shows good understanding of smoking risks with oxygen therapy. Choice C demonstrates awareness of equipment maintenance. Choice D indicates compliance with the provider's instructions. However, B is the only statement that suggests a potential misunderstanding of oxygen therapy management.

Correct Answer: A

Rationale: The correct answer is A: Signs of peripheral neuropathy. Isoniazid can cause peripheral neuropathy due to vitamin B6 deficiency. The nurse should monitor for numbness, tingling, or weakness in extremities. Choices B, C, and D are incorrect because isoniazid does not typically cause hearing loss, visual disturbances, or hair thinning.

Correct Answer: C

Rationale: Certainly. The correct answer is C, providing oral care with chlorhexidine. This action helps reduce the risk of VAP by decreasing the oral bacterial load, preventing aspiration of pathogens into the lungs. Suctioning the airway every 2 hours (A) can irritate the airway and increase the risk of infection. Administering antibiotics prophylactically (B) can lead to antibiotic resistance and should be reserved for specific indications. Keeping the patient sedated (D) may increase the risk of aspiration due to reduced cough reflex.

Correct Answer: B

Rationale: The correct answer is B because in a critical situation like severe respiratory distress, immediate actions are crucial. Asking focused questions about the current episode will provide essential information for quick decision-making and interventions. It helps in assessing the severity of the distress, identifying potential causes, and determining the appropriate initial treatment. Obtaining a comprehensive health history (choice A) can be important but not urgent in this acute situation. Delaying assessment for pulmonary function tests (choice C) can be detrimental as it can delay necessary interventions. Checking for allergies before treatment (choice D) is important but not the priority when the patient is in severe distress.

Correct Answer: C

Rationale: The correct answer is C: Provide low-flow oxygen therapy. In COPD, hypoxemia (low PaO2) is the primary concern. Administering oxygen can help improve oxygenation and prevent further complications. Bronchodilators (choice A) may be indicated for symptom relief but not the priority. Pursed-lip breathing (choice B) can help with exhalation and symptom management but does not address the immediate hypoxemia. Assessing the patient's level of consciousness (choice D) is important but providing oxygen to improve oxygenation takes precedence in this case.
