Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. When a client with asthma develops wheezing, the primary action is to administer bronchodilators to help dilate the airways and improve breathing. This helps relieve the symptoms of wheezing and prevent further complications. Providing pain relief (Choice B) is not the primary action for wheezing in asthma. Encouraging deep breathing (Choice C) may worsen the wheezing in an asthma attack. Performing chest physiotherapy (Choice D) is not the first-line treatment for wheezing in asthma.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. This is the most important intervention for a client with an obstructed airway because it helps to ensure that the patient is receiving adequate oxygen supply to prevent hypoxia. Oxygen therapy can help maintain oxygen saturation levels and support proper gas exchange in the lungs. Monitoring respiratory rate (B) is important but not as critical as ensuring oxygen supply. Administering morphine (C) is contraindicated as it can depress respiratory function further. Administering fluids (D) is not the priority in managing an obstructed airway.

Correct Answer: D

Rationale: A focused assessment is more in-depth on specific issues, providing detailed information on a particular problem or concern. This allows for targeted interventions and treatment strategies. In contrast, a comprehensive assessment covers the body head to toe and involves all body systems, which may not be necessary when focusing on a specific issue. Occurring only in the clinic is a limitation to choice B, as assessments can be conducted in various settings. Involving all body systems, as stated in choice C, is not the primary focus of a focused assessment.

Correct Answer: B

Rationale: The given ABG values fall within normal ranges, indicating homeostasis. The pH is within the normal range (7.35-7.45), indicating acid-base balance. The PO2 is slightly lower but still within the normal range (80-100 mmHg). PCO2 falls within the normal range (35-45 mmHg), showing effective ventilation. The HCO3 level is also within the normal range (22-26 mEq/L), indicating proper kidney function. Therefore, all values are within normal limits, reflecting a state of homeostasis. Other choices are incorrect as they suggest imbalances in acid-base status, which is not seen with these values.

Correct Answer: B

Rationale: Correct Answer: B - Administer oxygen Rationale: 1. Oxygen therapy is crucial in managing COPD exacerbation to improve oxygen saturation levels. 2. Adequate oxygenation is essential to prevent further respiratory distress and potential complications. 3. Oxygen therapy helps alleviate symptoms like shortness of breath and fatigue, improving overall comfort. 4. Monitoring oxygen saturation levels guides the effectiveness of treatment and ensures appropriate oxygen delivery. Summary: - Administering corticosteroids (A) may help reduce inflammation in COPD exacerbation but does not address the immediate need for oxygen. - Monitoring respiratory rate (C) is important but prioritizing oxygen administration is more critical for immediate respiratory support. - Administering diuretics (D) may be indicated in certain cases of COPD exacerbation with fluid retention but is not the priority over oxygen therapy.
