Correct Answer: C

Rationale: The correct answer is C. An SPF of at least 15 is recommended to effectively protect against harmful UV rays. A sunscreen with an SPF of 10 is insufficient and does not provide adequate protection against skin cancer. Choices A, B, and D demonstrate good understanding of sun protection measures, such as avoiding peak sun hours, wearing protective clothing like a wide-brimmed hat, and reapplying sunscreen every 2 hours, which are all effective strategies to prevent skin cancer.

Correct Answer: C

Rationale: The correct first action the nurse should take when preparing to administer packed RBCs to a client is to verify the client's identification with another nurse. This is crucial to ensure that the correct blood product is administered to the correct client, minimizing the risk of a transfusion reaction. Administering an antihistamine prior to transfusion (Choice A) is not the first priority and is not a standard practice. While checking the client's vital signs (Choice B) is important, verifying the client's identification takes precedence to prevent a critical error. Priming the IV tubing with normal saline (Choice D) is a necessary step in the process but should occur after verifying the client's identity.

Correct Answer: B

Rationale: The correct intervention for a client experiencing alcohol withdrawal is to administer lorazepam. Lorazepam, a benzodiazepine, is commonly used to manage the symptoms of alcohol withdrawal by preventing seizures and reducing agitation and anxiety. Encouraging frequent ambulation (choice A) may not be safe during alcohol withdrawal due to potential instability and confusion. Providing a low-calorie diet (choice C) is not a priority during alcohol withdrawal, as the focus is on managing withdrawal symptoms. Administering insulin as prescribed (choice D) is unrelated to managing alcohol withdrawal symptoms.

Correct Answer: B

Rationale: Using dedicated equipment for a neutropenic client, such as a stethoscope, helps prevent infections. Neutropenic clients have a weakened immune system, making them vulnerable to infections from common pathogens. Wearing an N95 respirator is not necessary unless airborne precautions are required. Inserting a urinary catheter should be avoided unless necessary to prevent introducing pathogens. Monitoring vital signs should be done more frequently, typically every 4 hours, to promptly identify any changes in the client's condition.

Correct Answer: B

Rationale: The correct action for the nurse to take first when a client with a nasogastric tube reports feeling nauseated is to check the client's bowel sounds. This assessment helps the nurse evaluate for possible complications, such as a blockage or decreased gastric motility, that could be causing the nausea. Administering an antiemetic (Choice A) should not be the first action without assessing the underlying cause of the nausea. Slowing the rate of the feeding (Choice C) may be appropriate but is not the priority until further assessment is done. Placing the client in a supine position (Choice D) is not typically indicated for managing nausea in this situation.
