Correct Answer: A

Rationale: The correct answer is A: Liver. The liver is responsible for the extensive metabolism of acetaminophen through various pathways, including glucuronidation, sulfation, and oxidation. It converts acetaminophen into less toxic metabolites for elimination. The kidneys (B) primarily filter blood and regulate fluid balance; the lungs (C) are involved in gas exchange; and the pancreas (D) produces digestive enzymes and insulin, not involved in acetaminophen metabolism. Therefore, the liver is the correct choice for this question.

Correct Answer: D

Rationale: Correct Answer: D - Administering oxygen Rationale: 1. Oxygen is crucial in acute myocardial infarction to improve oxygenation and reduce myocardial workload. 2. Administering oxygen helps alleviate ischemia and prevents further damage. 3. Prioritizing oxygenation before pain medication or assessment ensures immediate intervention for the patient's well-being. Summary of other choices: A: Administering pain medication - Important for comfort but not the priority in acute myocardial infarction. B: Performing a head-to-toe assessment - Necessary but not as urgent as ensuring oxygenation. C: Establishing an intravenous line - Helpful but not as critical as administering oxygen in this scenario.

Correct Answer: A

Rationale: The correct answer is A because a comprehensive assessment involves gathering a complete health history and conducting a thorough physical examination to evaluate the client's overall health status. This includes assessing past medical history, family history, current medications, lifestyle factors, and performing a head-to-toe physical examination. This holistic approach helps in identifying any potential health issues or risk factors. Choice B is incorrect because a specific focus on a body system is not comprehensive and may miss other important aspects of the client's health. Choice C is incorrect as emergency triage is a rapid assessment to determine the severity of a medical condition and prioritize treatment, not a comprehensive assessment. Choice D is incorrect because a specific assessment of client complaints is focused only on the reported issues and may not provide a comprehensive overview of the client's health.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. This is the most appropriate intervention for a wound infection as antibiotics target the underlying bacterial infection causing the wound infection. Antibiotics help to eliminate the infection and prevent it from spreading further. Administering antibiotics is crucial in treating wound infections to promote healing and prevent complications. Choice B (Apply sterile dressing) is incorrect as simply applying a sterile dressing does not address the underlying infection. Choice C (Cleanse and dress the wound) is also incorrect because while wound cleansing is important, it alone may not be sufficient to treat a wound infection. Choice D (Administer analgesics) is incorrect because analgesics only provide pain relief and do not address the infection itself.

Correct Answer: A

Rationale: The correct answer is A: Increasing physical activity and reducing salt intake. Firstly, increasing physical activity helps lower blood pressure by improving heart health and circulation. Secondly, reducing salt intake helps decrease fluid retention and lower blood pressure. The other choices are incorrect because B: Increasing alcohol consumption can raise blood pressure, C: Decreasing physical activity is counterproductive, and D: Increasing sodium intake can lead to higher blood pressure due to fluid retention. Prioritizing physical activity and reducing salt intake are evidence-based lifestyle changes to manage hypertension effectively.
