Correct Answer: C

Rationale: The appropriate ratio of chest compressions to rescue breaths for adult CPR is 30 compressions to 2 breaths. This means that after every 30 chest compressions, two rescue breaths should be given. This ratio helps in maintaining oxygen circulation in the body while also ensuring that the heart is being effectively pumped to circulate blood. The emphasis on chest compressions is critical in maintaining blood flow to vital organs during cardiac arrest, while the rescue breaths help in providing oxygen to the patient's lungs. This ratio is recommended by organizations like the American Heart Association for performing high-quality adult CPR.

Correct Answer: C

Rationale: Vocal cord nodules are benign growths on the vocal cords, typically caused by vocal abuse or misuse. The most appropriate intervention for managing vocal cord nodules is voice therapy and vocal hygiene education. Voice therapy aims to correct vocal habits and techniques that contribute to the formation of nodules, while vocal hygiene education focuses on maintaining vocal health through proper hydration, rest, and avoiding behaviors that strain the vocal cords. These interventions have been shown to be effective in reducing and eliminating vocal cord nodules without the need for surgical intervention. Surgery, such as vocal cord polypectomy or injection with corticosteroids, is typically reserved for cases that do not respond to conservative management or if there are significant complications. Partial laryngectomy is a more extensive surgical procedure that is not typically indicated for vocal cord nodules.

Correct Answer: A

Rationale: Stressing to all participants attending a health fair that a screening program is not a substitute for ongoing health supervision from a healthcare provider is crucial for several reasons. Health fairs are intended to provide a snapshot of an individual's health at a specific point in time and are not comprehensive assessments. Participants need to understand that these screenings are not a replacement for regular check-ups with their healthcare provider, who can provide continued monitoring, follow-up care, and more in-depth evaluations if necessary. It's important for participants to recognize that the results from a health fair screening are just one piece of their overall health picture and that ongoing care from a healthcare provider is essential for maintaining their well-being.

Correct Answer: B

Rationale: Identifying persons with sputum characterized as blood stained is important in case finding for pulmonary tuberculosis (PTB) in the community. Blood stained sputum, also known as hemoptysis, is a common symptom of TB. It occurs when there is bleeding in the respiratory tract, often as a result of damage to the lungs caused by tuberculosis infection. Therefore, the presence of blood in the sputum is a significant clinical finding that should alert healthcare providers, including nurses, to the possibility of TB. Early identification and diagnosis of individuals with blood stained sputum can lead to prompt treatment and the prevention of further transmission of the disease in the community.

Correct Answer: B

Rationale: The palliative nurse should prioritize performing thoracentesis to drain the pleural fluid and relieve dyspnea in a patient with terminal cancer experiencing pleural effusion. Pleural effusion is a common complication in patients with advanced cancer and can cause significant respiratory distress. Drainage of the pleural fluid through thoracentesis can provide immediate relief by easing the pressure on the lungs and improving the patient's ability to breathe. This intervention is essential in managing dyspnea for comfort and quality of life in palliative care settings. Administering bronchodilator medications (option A) or recommending non-invasive positive pressure ventilation (option C) may not directly address the underlying cause of dyspnea in this case. While relaxation techniques (option D) can help with anxiety and overall well-being, they may not be sufficient in managing the physical symptom of dyspnea caused by pleural effusion.
