A nurse is preparing a lecture about cancer prevention strategies for clients seeking to engage in health promotion. The nurse should include which of the following risk factors for the development of laryngeal cancer? (Select all that apply.)

A. Client develops petechiae on the arms, legs, and abdomen: Petechiae can indicate thrombocytopenia, which may be a complication of heparin therapy but is not an urgent concern unless severe or associated with bleeding.

B. Health care provider orders Coumadin 2.5 mg P.O. to begin today: Coumadin (warfarin) is often initiated as a bridge therapy or overlap with heparin therapy in pulmonary embolism management. This order is not necessarily inappropriate and may be part of the treatment plan.

C. Client develops slight ecchymosis at the venipuncture site: Ecchymosis at the venipuncture site can occur due to minor trauma during the insertion of IV lines or blood draws and is not necessarily indicative of a complication requiring immediate notification of the healthcare provider.

D. Client's partial thromboplastin time (PTT) is 70 seconds and the control is 25-40 seconds: A significantly elevated PTT indicates a potential overdose of heparin, putting the client at risk of bleeding complications. This finding warrants immediate notification of the healthcare provider for further evaluation and possible adjustment of heparin therapy.

The nurse should first place the client in high Fowler's position to ease the breathing and improve oxygenation, as the client is experiencing increased dyspnea and chest pain. This position allows for better lung expansion and can be a critical immediate intervention. Following this, the nurse should obtain IV access to facilitate the administration of medications and fluids as needed. IV access is essential for the rapid administration of potential treatments, including anticoagulants, which may be required if a pulmonary embolism is confirmed. These actions are prioritized to address the client's immediate respiratory distress and to prepare for further interventions based on the evolving clinical situation. It is important to note that each clinical scenario is unique, and the interventions should be tailored to the client's specific needs and the healthcare provider's clinical judgment.
