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.

A. Obtain pulse oximetry every two hours: While monitoring oxygen saturation is important in assessing respiratory status, it is not a direct intervention for preventing atelectasis. It is more of an assessment tool to evaluate the effectiveness of interventions aimed at preventing atelectasis.

B. Teach the client how to use the incentive spirometer: Incentive spirometry is a valuable tool for preventing atelectasis postoperatively by promoting deep breathing and lung expansion. Teaching the client how to use the incentive spirometer and encouraging its frequent use can help maintain lung volume and prevent collapse of alveoli.

C. Instruct the client to practice abdominal breathing: While abdominal breathing can be beneficial for promoting relaxation and reducing anxiety, it is not as effective as incentive spirometry in preventing atelectasis postoperatively.

D. Encourage oral fluid intake of 2000 mL/24 hours: Adequate hydration is important for overall health and respiratory function, but it is not specifically targeted at preventing atelectasis. While hydration can help maintain airway secretions thin, it is not the primary intervention for preventing atelectasis after a lobectomy.
