The practical nurse (PN) is working in a cancer detection mobile clinic. Four individuals come for screening with a complaint of hoarseness, a danger sign for cancer of the larynx. Which client has the highest risk for development of cancer of the larynx that the PN should refer to the healthcare provider?

A. An office manager whose mother has laryngeal cancer: Family history can increase risk slightly, but environmental and lifestyle factors, particularly smoking and heavy alcohol use, are stronger contributors to laryngeal cancer. B. A farmer who smokes a half pack of cigarettes daily: Smoking increases risk, but the level of exposure is relatively low compared with heavy, long-term use combined with alcohol consumption. C. An older male who drinks a six-pack of beer nightly and smokes heavily: Chronic heavy alcohol use combined with long-term heavy smoking significantly increases the risk of laryngeal cancer. This client exhibits multiple high-risk behaviors and should be prioritized for referral. D. An opera singer who does not smoke but drinks a glass of wine each day: Moderate alcohol consumption without smoking or other risk factors represents a lower risk for laryngeal cancer compared with heavy alcohol use and smoking.
