Correct Answer: C

Rationale: Instructing the client to avoid the Valsalva maneuver is crucial after rhinoplasty to reduce strain and the risk of bleeding. Administering humidified oxygen may not be directly related to postoperative care for rhinoplasty. Restricting fluids is not typically necessary unless specifically indicated by the healthcare provider. Applying heat packs to the nose is contraindicated after rhinoplasty as it can increase the risk of bleeding and should be avoided.

Correct Answer: B

Rationale: When a client develops phlebitis at the IV site, the immediate action the nurse should take is to discontinue the IV and notify the provider. Phlebitis is inflammation of the vein, and if left untreated, it can lead to serious complications such as infection, thrombosis, or sepsis. Removing the IV line helps prevent further irritation and infection. Applying a warm compress (Choice A) may provide some relief but does not address the root cause. Monitoring for signs of infection (Choice C) is important but not the immediate action needed to address phlebitis. Administering an anti-inflammatory medication (Choice D) may be prescribed by the provider but is not the first step in managing phlebitis.

Correct Answer: A

Rationale: The correct nursing intervention for a patient receiving anticoagulant therapy is to monitor INR levels and check for signs of bleeding. Monitoring the INR levels helps assess the effectiveness and safety of anticoagulant therapy, while checking for bleeding is essential due to the increased risk associated with anticoagulants. Choice B is incorrect as antiplatelet therapy is not the standard treatment for patients on anticoagulant therapy. Choice C is incorrect as providing additional anticoagulation is not a direct nursing intervention in this scenario. Choice D is incorrect because administering aspirin, an antiplatelet medication, along with anticoagulants can increase the risk of bleeding and is generally avoided.

Correct Answer: B

Rationale: The correct process for taking a telephone order from a provider involves reading back the information for accuracy. This step ensures that the order is correctly understood and reduces the risk of errors. While listing patient information (Choice A) is essential, it does not encompass the complete process of verifying the order. Having a witness listen to the order (Choice C) may not always be practical or necessary, as direct verification is more efficient. Writing down the order and following up (Choice D) is not as crucial as the immediate read-back process, which allows for real-time clarification and confirmation.

Correct Answer: B

Rationale: The most appropriate nursing intervention when a client with a nasogastric tube experiences nausea and a decrease in gastric secretions is to aspirate the gastric contents with a syringe. This action helps relieve nausea by removing excess fluid and gas. Option A, irrigating the nasogastric tube with distilled water, is not indicated as it does not address the underlying issue of decreased gastric secretions. Option C, administering an antiemetic medication, may provide symptomatic relief but does not address the mechanical issue of decreased flow in the nasogastric tube. Option D, inserting a new nasogastric tube, is not necessary unless there are specific complications or obstructions in the current tube.
