ATI RN Adult Medical Surgical Online Practice 2023 A

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: In a client with a high respiratory rate, low PaO2, and low SaO2, the priority intervention is to improve oxygenation. Administering oxygen via a face mask will help increase the oxygen supply to the client's lungs and tissues, addressing the hypoxemia. While mechanical ventilation may be necessary in severe cases, administering oxygen is the initial and most appropriate intervention to address the client's respiratory distress. Sedatives should not be given without ensuring adequate oxygenation. Assessing for pulmonary embolism is important but not the priority at this moment when the client is experiencing respiratory distress and hypoxemia.

Correct Answer: A

Rationale: After a flexible bronchoscopy, it is crucial to withhold food and liquids until the client's gag reflex returns to prevent aspiration. Irrigating the client's throat every 4 hours, having the client refrain from talking for 24 hours, and frequent suctioning of the oropharynx are not indicated post-bronchoscopy and may even pose risks to the client's recovery.

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.
