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.

Correct Answer: B

Rationale: Cyanosis unresponsive to oxygen therapy suggests methemoglobinemia, an adverse effect of benzocaine spray. Methemoglobinemia can lead to death if not managed promptly. The nurse should notify the Rapid Response Team to provide immediate advanced care. Administering albuterol would not address the underlying cause of cyanosis. Assessing peripheral pulses and obtaining cultures are not the priority as they do not directly address the urgent need to manage methemoglobinemia.

Correct Answer: B

Rationale: The diet recommended for this client would be low in saturated fats & red meat, high in vegetables & whole grains (fiber), low in salt, & low in trans-fat. The best choice is the chicken with broccoli & tomatoes. The French fries have too much fat & the iceberg lettuce has little fiber. The catfish is fried. The spaghetti dinner has too much red meat & no vegetables.

Correct Answer: A

Rationale: The correct answer is A. Effective oxygen therapy should improve the client's ability to perform activities without dyspnea. This indicates that the oxygen therapy is adequately supporting the client's respiratory needs. An oxygen saturation of 92% may suggest the need for a higher flow rate to improve oxygenation. A respiratory rate of 24 breaths per minute is elevated, indicating potential respiratory distress. A productive cough does not necessarily indicate effective oxygen therapy, as it is a symptom of respiratory irritation or infection, not oxygenation status.

Correct Answer: A

Rationale: Clients with COPD commonly develop a barrel chest, characterized by an increased anteroposterior diameter of the chest. This change is due to chronic air trapping and hyperinflation of the lungs. A decreased respiratory rate, weight gain, and productive cough with yellow sputum are not typical findings in COPD. Instead, COPD patients often present with an increased respiratory rate, weight loss, and a chronic cough with sputum production.
