ATI RN Adult Medical Surgical Online Practice 2023 A

Correct Answer: B

Rationale: When a client develops an airway obstruction and remains conscious, the nurse's initial action should be to administer the abdominal thrust maneuver. This technique, also known as the Heimlich maneuver, can help dislodge the obstructing object and clear the airway. Inserting an oral airway, turning the client to the side, or performing a blind finger sweep are not recommended as the first interventions for a conscious individual with an airway obstruction.

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: A

Rationale: In this situation, the priority action is to provide high-flow oxygen to the client. Sudden onset dyspnea and severe chest pain can be indicative of a pulmonary embolism, which is a life-threatening emergency. Oxygen therapy helps improve oxygenation and stabilizes the client's condition. Checking for Chvostek's sign, administering IV vasopressors, or monitoring for a headache are not the immediate priorities in this critical situation.

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: A

Rationale: In a client with multiple system trauma, airway protection is the priority focus of care. Ensuring a patent airway is crucial for oxygenation and ventilation, which are essential for maintaining vital functions. Without a clear airway, the client's oxygenation and ventilation could be compromised, leading to severe consequences. While decreasing intracranial pressure, stabilizing cardiac arrhythmias, and preventing musculoskeletal disability are important aspects of care, ensuring airway protection takes precedence in this emergency situation.
