As part of primary cancer prevention program, an oncology nurse answers questions from the public at health fair. When someone asks about the laryngeal cancer, the nurse should explain that:

Correct Answer: A

Rationale: Laryngeal cancer is indeed one of the most preventable types of cancer. The primary risk factors for laryngeal cancer include tobacco use (particularly smoking) and excessive alcohol consumption. Therefore, avoiding tobacco products, moderating alcohol intake, and maintaining a healthy lifestyle can significantly reduce the risk of developing laryngeal cancer. Additionally, early detection through regular check-ups and screenings can help in detecting any precancerous or cancerous changes in the larynx, leading to better treatment outcomes and prognosis.

Correct Answer: C

Rationale: A malignant tumor is characterized by its ability to spread to surrounding tissues and potentially enter the bloodstream to form secondary tumors in distant organs (metastasis). In the scenario provided, the tumor in Miss OB's left breast is described as spreading all over the surrounding and adjacent tissue but specifically noted not to be entering the bloodstream. This behavior is more indicative of a benign tumor that is growing locally but is not capable of metastasis. Therefore, the tumor is best classified as benign in this case.

Correct Answer: A

Rationale: Oxygen saturation above 90% is a discharge criterion from the PACU (Post-Anesthesia Care Unit) for a patient following surgery. This indicates that the patient is effectively exchanging oxygen and carbon dioxide, which is essential for proper respiratory function. Adequate oxygenation is crucial for the patient to be safely discharged from the PACU and transitioned to a regular hospital room or home. Monitoring oxygen saturation helps ensure that the patient's respiratory status is stable before leaving the PACU. If a patient's oxygen saturation is below 90%, further assessment and interventions may be necessary before discharge is considered.

Correct Answer: C

Rationale: Decreased cardiac output is a serious concern in clients with congestive heart failure. By assessing the apical heart rate before administering digitalis, the nurse can monitor the client's cardiac status and prevent possible complications such as digitalis toxicity. Digitalis is a medication commonly used to improve cardiac output in clients with heart failure, but it can also cause harm if given inappropriately, especially if the client's heart rate is already low. Monitoring the client's apical heart rate before giving digitalis helps ensure that the medication is safely administered and that the client's cardiac status is closely monitored. This intervention is crucial in the care of clients with congestive heart failure to optimize patient safety and outcomes.
