Correct Answer: A

Rationale: The correct answer is African American churches. African Americans in the United States have one of the highest rates of hypertension globally. By providing services at African American churches, the nurse can effectively reach this priority population. While hypertension education and screening are essential for all groups, African Americans are the priority population for this intervention due to their disproportionately high rates of hypertension.

Correct Answer: B

Rationale: Immediate intervention is necessary when a client with a mediastinal chest tube exhibits tracheal deviation since it may indicate a tension pneumothorax. This condition requires prompt attention to prevent serious complications. While the production of pink sputum and pain at the insertion site should be monitored and reported, they do not typically require immediate intervention. Sudden onset of shortness of breath could indicate various issues related to the chest tube but is not as critical as tracheal deviation in this context.

Correct Answer: D

Rationale: In chronic obstructive pulmonary disease, it's important to consider the impact of nutrition on respiratory function. Eating high-fiber foods can lead to increased gas production, causing abdominal bloating and potentially worsening shortness of breath. Therefore, it is advisable for clients with COPD to avoid high-fiber foods to prevent these issues. Resting before meals can help manage dyspnea, and having smaller, more frequent meals can prevent bloating. Increasing calorie and protein intake is essential to prevent malnourishment in COPD patients. Additionally, limiting carbohydrate intake is crucial as it can increase carbon dioxide production, leading to a higher risk of acidosis in these individuals.

Correct Answer: C

Rationale: Pursed-lip breathing is a common manifestation in clients with emphysema. It helps to increase the duration of exhalation and reduce air trapping, aiding in the management of the condition. Decreased chest expansion and bradypnea are not typically associated with emphysema. While cyanosis can occur in severe cases, pursed-lip breathing is a more specific and commonly observed sign of emphysema.

Correct Answer: A

Rationale: In COPD, the client often develops a barrel chest, characterized by an increased anterior-posterior diameter of the chest. This change is due to air trapping and hyperinflation of the lungs. Decreased respiratory rate, weight gain, and productive cough with yellow sputum are not typically associated with COPD. Weight loss is more common due to increased work of breathing and decreased energy expenditure in individuals with COPD.
