How should a healthcare professional monitor a patient with a central line for infection?

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 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.

Correct Answer: A

Rationale: Administering oxygen is the best nursing action for a patient experiencing shortness of breath as it helps alleviate the symptoms and improve oxygenation. Providing oxygen addresses the primary issue of inadequate oxygen levels in the body, which can be a life-threatening situation. Administering bronchodilators (choice B) may be appropriate for specific respiratory conditions like asthma but is not the initial intervention for all causes of shortness of breath. Repositioning the patient (choice C) can sometimes help improve breathing, but in a patient experiencing significant shortness of breath, immediate oxygen therapy is crucial. Providing IV fluids (choice D) is not indicated as the first-line intervention for shortness of breath unless there is a specific underlying cause such as dehydration.

Correct Answer: A

Rationale: Administering oxygen is the priority intervention for a patient with suspected pulmonary embolism. Maintaining adequate oxygenation is crucial in these patients to prevent hypoxemia and support oxygen delivery to tissues. Administering anticoagulants may be necessary but is not the initial priority. Administering bronchodilators is not indicated for pulmonary embolism. Repositioning the patient does not address the immediate need for oxygenation.

Correct Answer: A

Rationale: Administering oxygen is the initial step in managing a suspected pulmonary embolism. Oxygen therapy is crucial to improve oxygenation levels in the blood when there is a suspected blockage in the pulmonary artery. Administering anticoagulants, although important in the treatment of pulmonary embolism, is not the first step as ensuring adequate oxygen supply takes precedence. Repositioning the patient or administering IV fluids are not the primary interventions for a suspected pulmonary embolism and are not as essential as providing oxygen support.
