What is the most important nursing action when a patient has a central line?

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 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.

Correct Answer: A

Rationale: Monitoring daily weight is the most accurate way to assess fluid overload in patients with heart failure. In heart failure, the body retains excess fluid, leading to weight gain. Monitoring daily weight allows healthcare professionals to track fluid retention accurately. Checking for edema (Choice B) is a valuable assessment technique, but it may not be as sensitive as monitoring daily weight. Monitoring blood pressure (Choice C) is essential in managing heart failure, but it is not the most accurate way to assess fluid overload. Checking oxygen saturation (Choice D) is important to assess respiratory status but is not directly related to fluid overload in heart failure.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Administering oxygen is the priority intervention for a patient with a suspected pulmonary embolism to improve oxygenation levels. In pulmonary embolism, there is a blockage in one of the pulmonary arteries, leading to decreased oxygen exchange. Administering oxygen helps increase oxygen saturation levels. Anticoagulants (Choice B) are essential in the treatment of pulmonary embolism but are not the initial priority intervention. Surgery (Choice C) is not typically the first-line treatment for pulmonary embolism. Monitoring oxygen saturation (Choice D) is important but administering oxygen takes precedence as the immediate action to address hypoxemia.
