Correct Answer: A

Rationale: When a client is receiving oxygen at a high flow rate, it can cause drying of the nasal passages and lips. Therefore, a comfort measure that can be delegated to unlicensed assistive personnel (UAP) is applying water-soluble ointment to the client's nares and lips. Adjusting the oxygen flow rate should be done by licensed nursing staff, not UAP. Removing the tubing can disrupt the oxygen delivery and should be performed by trained personnel. Turning the client every 2 hours is a general comfort measure but is not specific to addressing the drying effects of oxygen therapy.

Correct Answer: B

Rationale: Most people with hypertension are asymptomatic, although a small percentage do have symptoms such as headache. The nurse should explain this to the client. Asking about paying for medications is not related because the client has already admitted nonadherence. Threatening the client with possible complications will not increase compliance.

Correct Answer: D

Rationale: While some of the other options may be helpful, the most appropriate advice for a client with COPD is to consume high-fiber foods to promote gastric emptying. Avoiding fluids just before and during meals can help prevent bloating, resting before meals can assist with dyspnea, and having several small meals a day can help reduce bloating. However, fibrous foods can lead to gas production, causing abdominal bloating and potentially worsening shortness of breath. Increasing calorie and protein intake is essential to prevent malnourishment. It is also important to avoid excessive carbohydrate intake, as it can increase carbon dioxide production and the risk of acidosis in COPD patients.

Correct Answer: C

Rationale: In pneumonia, lung tissue consolidation occurs, leading to dullness on percussion. This is a typical finding in pneumonia. Fremitus and decreased tactile fremitus are more commonly associated with conditions like pleural effusion or pneumothorax. Hyperresonance is typically seen in conditions causing air trapping, such as emphysema.

Correct Answer: C

Rationale: Pneumonia often leads to the consolidation of lung tissue, resulting in dullness on percussion. This occurs due to the presence of fluid or inflammatory material in the alveoli. Fremitus and decreased tactile fremitus are more indicative of conditions like pleural effusion or pneumothorax, where there is an increase in the density of the pleural space or air in the pleural cavity. Hyperresonance, on the other hand, is typically associated with conditions causing air trapping, such as emphysema, where there is increased air in the alveoli.
