A nurse is caring for a patient who has just been diagnosed with tuberculosis (TB). What is the priority nursing action?

Correct Answer: B

Rationale: The correct answer is B, administer rifampin. The priority in caring for a patient with TB is to start anti-TB medications promptly to prevent the spread of the infection. Rifampin is one of the first-line drugs used to treat TB. Administering a PPD test (A) is important for diagnosis but not the priority at this moment. Administering an injectable antihistamine (C) is not indicated for TB treatment. Administering oxygen therapy (D) may be necessary based on the patient's condition but treating the underlying infection with rifampin takes precedence.

Correct Answer: D

Rationale: The correct answer is A: Encourage early ambulation. This is the priority intervention to prevent DVT because it promotes blood circulation and prevents stasis in the veins. - Option B: Administer a platelet aggregation inhibitor is incorrect as it is not the first-line intervention for preventing DVT. - Option C: Administer anticoagulants may be used in some cases, but it is not the priority intervention. - Option D: Monitor the patient's oxygen saturation levels is not directly related to preventing DVT and is not the priority intervention.

Correct Answer: C

Rationale: The correct answer is C: Administer insulin. Blurred vision in a patient with a history of diabetes could indicate hyperglycemia. Administering insulin would help lower blood glucose levels and alleviate the blurred vision. Monitoring blood glucose levels (choice A) is important but not the priority when the patient is already experiencing symptoms. Administering insulin (choices B and D) is the immediate action needed to address the high blood glucose levels causing the blurred vision.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In heart failure, fatigue and weakness can be due to poor oxygenation. Administering oxygen helps improve oxygen levels, alleviating symptoms. Insulin (B) is not indicated for fatigue in heart failure. Antibiotics (C) are not necessary unless there is a confirmed infection. Beta-blockers (D) may be part of the treatment plan but addressing oxygenation is the priority in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Administer a bronchodilator. The priority intervention for a patient with asthma experiencing shortness of breath is to administer a bronchodilator to help open up the airways and improve breathing. Bronchodilators work quickly to relieve acute symptoms of asthma by relaxing the muscles around the airways. This intervention is crucial in managing an acute asthma exacerbation. Summary: - Option B: Administer insulin therapy is incorrect because it is not indicated for managing asthma exacerbation. - Option C: Administer short-acting bronchodilators is partially correct but not as specific as option A, which specifies the immediate need for bronchodilator therapy. - Option D: Administer corticosteroids is important for long-term control of asthma but not the priority intervention in an acute exacerbation where immediate relief is needed.
