A nurse is prioritizing care for multiple patients. Which action should the nurse prioritize?

Choice A reason: Positioning a post-hip surgery patient prevents complications like dislocation or pressure ulcers. However, this is less urgent than new-onset chest pain, which may indicate a life-threatening condition like myocardial infarction. Proper positioning is important but secondary to addressing acute cardiovascular symptoms. Choice B reason: Increasing oxygen flow for wheezing improves oxygenation in conditions like asthma or COPD. While important, wheezing is less immediately life-threatening than chest pain, which could signal acute coronary syndrome or pulmonary embolism, requiring urgent assessment to prevent cardiac or respiratory failure. Choice C reason: Taking vital signs provides general stability data but is not specific enough to address acute symptoms like chest pain. Vital signs are part of a comprehensive assessment but are secondary to evaluating new-onset chest pain, which may indicate a life-threatening cardiovascular or pulmonary event. Choice D reason: New-onset chest pain may indicate myocardial infarction, pulmonary embolism, or aortic dissection, all life-threatening conditions requiring immediate assessment. Prompt evaluation, including ECG and oxygen saturation, guides interventions to prevent cardiac arrest or organ damage, making this the highest priority among the listed actions.
