Correct Answer: B

Rationale: The correct instruction is to rinse the mouth after each use of a corticosteroid inhaler to prevent oral candidiasis (thrush). Choice A is incorrect because corticosteroid inhalers are usually used on a regular schedule to control asthma symptoms, not just for acute symptoms. Choice C is incorrect as corticosteroid inhalers are typically used for long-term management, not just during asthma attacks. Choice D is incorrect as administering a bronchodilator after using a corticosteroid is not a standard practice and is not necessary for the effectiveness of the corticosteroid inhaler.

Correct Answer: A

Rationale: The correct action for the nurse to take first when a client reports chills during a blood transfusion is to stop the transfusion. Chills can indicate a transfusion reaction, which is a potentially serious situation. Stopping the transfusion immediately is crucial to prevent further complications. Administering acetaminophen or checking the client's blood pressure can come after ensuring the safety of the client by stopping the transfusion. Notifying the provider is important, but the immediate priority is to stop the transfusion.

Correct Answer: D

Rationale: Corrected Rationale: Chicken breast is an excellent source of protein, which is essential for wound healing due to its role in tissue repair and regeneration. Fish is also a good source of protein, but chicken breast is a more commonly recommended option for wound healing due to its high protein content and lower fat content compared to some types of fish. Bananas and white bread, on the other hand, are not high-protein foods and do not provide the necessary nutrients for wound healing.

Correct Answer: A

Rationale: Verifying the patient's identity is a critical step when administering a blood transfusion to ensure that the correct blood product is given to the right patient. This process helps prevent errors and enhances patient safety. Choice B, 'Administer medication,' is incorrect because the focus during a blood transfusion should be on ensuring the correct blood product is administered. Choice C, 'Monitor vital signs,' is also important but comes after verifying the patient's identity. Choice D, 'Start blood transfusion without verification,' is incorrect and unsafe as patient identification verification is essential prior to starting any medical procedure, especially one as important as a blood transfusion.

Correct Answer: A

Rationale: The correct answer is to administer anticoagulants. Anticoagulants help prevent further clot formation in patients with suspected DVT. Encouraging ambulation can be beneficial in preventing DVT but is not the immediate intervention for a suspected case. Compression stockings are more for DVT prevention rather than treatment. Monitoring oxygen saturation is important in assessing respiratory function but is not the primary intervention for suspected DVT.
