Correct Answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

Correct Answer: D

Rationale: When caring for a client with dysphagia, it is crucial to ensure safe feeding practices. Assigning an assistive personnel to feed the client slowly may not be appropriate as it can increase the risk of aspiration. Thickened liquids, having suction equipment available, and placing food on the unaffected side of the mouth are all appropriate measures to support a client with dysphagia in safe eating and drinking.

Correct Answer: C

Rationale: Taking prednisone with meals can help reduce the risk of gastrointestinal upset and irritation. It is important for the client to understand how to take the medication correctly to maximize its effectiveness and minimize potential side effects. Monitoring for weight loss or changes in stools may be important but does not directly relate to the administration of the medication with meals.

Correct Answer: C

Rationale: Stripping the drainage tubing is an outdated practice and can cause complications. Encouraging the client to cough helps with lung expansion, checking for continuous bubbling ensures proper functioning of the chest tube system, and obtaining a chest x-ray helps to assess the position of the chest tube and re-expansion of the lung. Therefore, stripping the drainage tubing every 4 hours should not be included in the plan of care.

Correct Answer: B

Rationale: When assessing a client with a history of asthma, the nurse should identify environmental allergies as a risk factor for asthma. Environmental allergens such as pollen, dust mites, mold, and pet dander can trigger asthma symptoms and exacerbate the condition. Gender, alcohol consumption, and other factors may not directly contribute to the development or exacerbation of asthma.
