Correct Answer: C

Rationale: In respiratory acidosis, there is an excess of carbon dioxide (PaCO2 > 45 mm Hg) leading to a decrease in pH (<7.35). The given values of a pH of 7.3 and PaCO2 of 50 mm Hg indicate respiratory acidosis. Metabolic acidosis involves a primary decrease in bicarbonate levels with a compensatory decrease in PaCO2 to maintain balance. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory alkalosis is marked by low PaCO2 and increased pH levels.

Correct Answer: D

Rationale: During an acute asthma exacerbation, the priority intervention is to administer a nebulized beta-adrenergic medication, such as albuterol, to help open the airways and improve breathing. This action helps address the underlying cause of the exacerbation. Oxygen therapy may be needed but is not the priority over administering the bronchodilator. Providing rest and positioning the client in high-Fowler's are important but come after administering the medication to address the immediate breathing difficulties.

Correct Answer: B

Rationale: Keeping the collection device below the level of the client's chest ensures proper drainage and prevents backflow of fluid into the patient's chest. This position allows gravity to assist in the drainage process. Clamping the tube when the client is ambulating can cause a buildup of pressure in the chest drainage system, potentially leading to complications. Carefully coiling the tubes is important to prevent obstructions and kinks that could impede the flow of drainage. Positioning the client flat may not be ideal as it could hinder proper drainage and increase the risk of leaks in the tubing.

Correct Answer: B

Correct Answer: A

Rationale: Continuous bubbling in the water-seal chamber indicates air is leaking into the pleural space, which is a complication. The water-seal chamber should have intermittent bubbling during normal functioning. Occasional bubbling in the water-seal chamber is normal and shows the system is working as intended. Constant bubbling in the suction-control chamber suggests an issue with the suction control. Fluctuations in the fluid level in the water-seal chamber are an expected finding.
