Correct Answer: D

Rationale: The correct answer is 'I've been using my albuterol inhaler more frequently over the last 4 days.' This statement indicates that the patient may need teaching regarding medication use because an increased need for a rapid-acting bronchodilator suggests an exacerbation of asthma. The patient should be educated on recognizing worsening symptoms and the appropriate actions to take. Choices A, B, and C do not directly relate to asthma exacerbation or the need for medication teaching, making them incorrect. Choice A reflects a lack of recent acute asthma attacks, while choice B describes shortness of breath unrelated to medication use. Choice C mentions Tylenol use for chest-wall pain, which is not indicative of asthma exacerbation or medication teaching needs.

Correct Answer: A

Rationale: Paradoxic chest movement is the most concerning finding as it indicates a potential flail chest, which can lead to severe compromise in gas exchange and rapid hypoxemia. This condition requires immediate attention to prevent respiratory distress. Complaint of chest wall pain, a slightly elevated heart rate, and a large bruised area on the chest are important assessment findings but may not immediately threaten gas exchange or respiratory function. Therefore, identifying paradoxic chest movement is critical for prompt intervention and management.

Correct Answer: B

Rationale: Tuberculosis (TB) is prevalent in many parts of Asia, including Vietnam, and the incidence of TB is higher in immigrants from Vietnam compared to the general U.S. population. Conducting tuberculosis screening is crucial to identify and address any cases promptly, especially in a community with recent immigrants from Vietnam. While teaching about contraceptive use, providing colonoscopy information, and testing for hepatitis may be relevant for certain individuals in the community, they are not as universally important as tuberculosis screening due to the increased risk of TB among Vietnamese immigrants.

Correct Answer: C

Rationale: The drop in SpO2 to 88% indicates that the patient is hypoxemic and needs supplemental oxygen when exercising. Administering PRN supplemental oxygen is the priority action to correct the hypoxemia and ensure adequate oxygenation during activity. Notifying the healthcare provider can be done after stabilizing the patient's oxygen levels. Documenting the response to exercise is important but secondary to addressing the immediate hypoxemia. Encouraging the patient to pace activity is not sufficient to address the acute drop in SpO2 and provide the necessary oxygen support.

Correct Answer: D

Rationale: Directly observed therapy is the most effective means for ensuring compliance with the treatment regimen for a homeless patient with active tuberculosis. By arranging a daily noon meal at a community center where the drug will be administered, the nurse ensures that the patient is available to receive the medication and can directly observe the patient taking it. This method helps address the challenges faced by homeless individuals, such as lack of a stable living situation. The other options, such as having a friend administer the medication, giving written instructions, or educating about infecting others, may not be as effective in ensuring adherence, especially in the case of a homeless individual with alcoholism.
