What is the best intervention for a patient presenting with respiratory distress?

Correct Answer: A

Rationale: Administering oxygen is the most critical intervention for a patient in respiratory distress as it helps improve oxygenation levels. Oxygen therapy aims to increase oxygen saturation in the blood, providing relief and support during episodes of respiratory distress. Administering bronchodilators may be beneficial in some cases, but oxygen therapy takes precedence in addressing the underlying issue of inadequate oxygenation. Repositioning the patient may help optimize ventilation but does not directly address the primary need for increased oxygen. Providing humidified air can offer comfort but does not address the urgent need for improved oxygen levels in a patient experiencing respiratory distress.

Correct Answer: A

Rationale: Corrected Rationale: Potassium levels should be monitored closely in a patient receiving digoxin to avoid hypokalemia. Digoxin can increase the risk of developing life-threatening arrhythmias in the presence of low potassium levels. Monitoring sodium, calcium, or glucose levels is not specifically necessary for patients on digoxin, making choices B, C, and D incorrect.

Correct Answer: A

Rationale: Monitoring the dressing site daily is crucial for detecting early signs of infection in patients with central lines. Checking for redness and swelling (choice B) is important but may indicate a more advanced stage of infection. Monitoring for fever (choice C) can also be a sign of infection, but it is a later manifestation. Flushing the central line (choice D) is necessary for maintaining patency but does not directly monitor for infection.

Correct Answer: A

Rationale: The most important nursing action when a patient experiences a fall is to assess the patient for injuries. This is critical to identify any potential harm or underlying issues that may require immediate attention. Calling for help and notifying the healthcare provider are important steps, but assessing the patient's condition takes precedence to ensure prompt and appropriate care. Documenting the fall is also necessary but should follow the initial assessment and care provided to the patient.

Correct Answer: A

Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.
