The healthcare professional is preparing to administer a blood transfusion to a client with anemia. Which action is most important to prevent a transfusion reaction?

Correct Answer: C

Rationale: Verifying the blood type and Rh factor with another healthcare professional is the most crucial action to prevent a transfusion reaction. Ensuring compatibility between the donor blood and the recipient is essential in preventing adverse reactions such as hemolytic transfusion reactions. Checking vital signs is important for monitoring the client during the transfusion process but does not directly prevent a transfusion reaction. Using a blood filter can help remove clots and debris but does not address the risk of a reaction due to blood type incompatibility. Administering antihistamines before the transfusion is not a standard practice to prevent transfusion reactions related to blood type incompatibility.

Correct Answer: A

Rationale: The correct answer is A: Improved academic performance. Physical activity has been shown to improve academic performance by enhancing concentration and cognitive function. This benefit is particularly important for elementary school students who are developing foundational skills. Choice B, increased social interactions, while important for overall development, may not directly relate to the academic aspect that the nurse is focusing on. Choice C, enhanced physical strength, is a valid benefit of physical activity but may not be as relevant to academic performance as the ability to concentrate and learn. Choice D, better sleep patterns, is also a valuable outcome of physical activity but is not as directly linked to academic performance as improved cognitive function.

Correct Answer: B

Rationale: The correct answer is B: Distributing naloxone kits to first responders. Naloxone is a medication that can rapidly reverse opioid overdose, potentially saving lives. In an opioid crisis scenario, providing naloxone kits to first responders equips them to act swiftly in emergencies. Choice A, providing education on the dangers of opioid use, is important but may not be as immediately life-saving as naloxone distribution. Choice C, offering support groups, is valuable for long-term recovery but may not address the acute crisis of overdoses. Choice D, partnering with local pharmacies to monitor prescriptions, focuses on prevention rather than immediate response to overdoses.

Correct Answer: C

Rationale: A temperature of 102°F (38.9°C) is the most important assessment finding to report to the healthcare provider in a client with pancreatitis and a history of alcoholism. Fever in this context can indicate infection, which is a serious complication requiring immediate intervention. Nausea and vomiting (choice A) are common symptoms of pancreatitis but may not require immediate intervention unless severe. Epigastric pain radiating to the back (choice B) is a classic symptom of pancreatitis and should be addressed, but a fever takes precedence. Mild jaundice (choice D) may be present in pancreatitis but is not as urgent as a high temperature signaling possible infection.

Correct Answer: C

Rationale: In a client with a head injury, being drowsy but still arousable can be a sign of increased intracranial pressure, which necessitates immediate intervention. This presentation may indicate a deterioration in neurological status, requiring prompt assessment and management to prevent further complications. Choices A, B, and D are not indicative of an immediate need for intervention in this scenario. A Glasgow Coma Scale (GCS) score of 15 indicates the highest level of consciousness; pupils being equal and reactive to light suggest intact cranial nerve function, and memory loss about the injury event is common in head injuries and does not necessarily warrant immediate intervention.
