ATI RN Adult Medical Surgical Online Practice 2023 A

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: 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: 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.

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: Atelectasis is a condition where the alveoli in the lungs collapse, leading to impaired gas exchange. As a result, the client may experience increasing dyspnea (difficulty breathing) due to the decreased lung capacity for oxygen exchange. Facial flushing, decreasing respiratory rate, and friction rub are not typically associated with atelectasis.
