Correct Answer: D

Rationale: When a client expresses being short of breath, it may indicate a serious condition requiring immediate attention to ensure adequate oxygenation. This client should be seen first to assess the severity of the situation and initiate appropriate interventions. The other options, such as awaiting transport for an x-ray, having a prescription for discharge, or receiving oral pain medication 30 minutes ago, do not present immediate life-threatening concerns compared to a client experiencing shortness of breath.

Correct Answer: B

Rationale: Option B, 'I will take my bronchodilators after meals,' indicates a need for further teaching. Bronchodilators should be taken before meals to help open the airways and make breathing easier before eating. This statement suggests a misunderstanding of the timing for optimal bronchodilator effectiveness. Options A, C, and D are all appropriate strategies for facilitating eating for a client with chronic obstructive pulmonary disease.

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: 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

Rationale: When suspecting anaphylaxis, the priority intervention is to assess the client's respiratory status by counting the respiratory rate. Respiratory distress is a hallmark sign of anaphylaxis, and prompt recognition and management are crucial. Administering oxygen may be necessary, but assessing the respiratory rate takes precedence to determine the severity of the reaction and the need for immediate intervention. Inserting an IV line and preparing for intubation are important interventions in managing anaphylaxis but are secondary to ensuring adequate ventilation.
