How should a healthcare professional care for a patient with a central line to prevent infection?

Correct Answer: A

Rationale: Corrected Rationale: Changing the central line dressing daily is crucial in preventing infection at the insertion site. This practice helps maintain a clean and sterile environment around the central line, reducing the risk of pathogens entering the bloodstream. Monitoring for redness (choice B) is important but may not directly prevent infection. Checking the central line site every shift (choice C) is essential for early detection of any issues but does not solely prevent infection. Flushing the line with saline (choice D) is a necessary procedure for maintaining central line patency but does not primarily prevent infection.

Correct Answer: A

Rationale: The most important nursing action when a patient has a central line is to monitor for infection. Central line-associated bloodstream infections are a serious complication that can lead to severe outcomes. Monitoring for infection involves assessing the patient for signs and symptoms such as fever, chills, and hypotension. While monitoring the central line dressing, redness, and swelling are also important aspects of care, they are secondary to monitoring for infection as the primary focus should be on preventing serious complications.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators as the priority nursing intervention for a patient with an acute asthma attack. Bronchodilators help open the airways and improve airflow, which is crucial in managing acute asthma symptoms. Administering corticosteroids (Choice B) is also important in the treatment plan, but it is not the priority intervention during an acute attack. Providing supplemental oxygen (Choice C) may be necessary but is not the priority initial intervention. Starting IV fluids (Choice D) is not typically indicated as a priority intervention for an acute asthma attack.

Correct Answer: A

Rationale: The correct answer is to administer antihistamines as the initial intervention for a patient experiencing an allergic reaction. Antihistamines work to block the effects of histamine, a substance released during an allergic reaction, helping to relieve symptoms such as itching, swelling, and hives. Corticosteroids (Choice B) are sometimes used in severe cases to reduce inflammation, but they are not the first-line treatment for an allergic reaction. Administering oxygen (Choice C) may be necessary if the patient is having difficulty breathing, but it is not the first intervention. IV fluids (Choice D) are typically given for conditions like dehydration or shock, not as the primary intervention for an allergic reaction.

Correct Answer: A

Rationale: The correct way for a healthcare provider to monitor a patient with suspected deep vein thrombosis (DVT) is to check for leg swelling. Leg swelling is a common symptom of DVT and monitoring for this sign is crucial for early detection and intervention. Encouraging ambulation may be beneficial for preventing DVT but is not the recommended method for monitoring an existing condition. Checking for redness may be useful in cases of superficial thrombophlebitis but is not specific to DVT. Monitoring oxygen saturation is more relevant for respiratory or cardiovascular conditions, not for DVT.
