ATI RN Adult Medical Surgical Online Practice 2023 A

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: When the nurse observes the absence of left-sided chest wall expansion upon respiration, it indicates that the endotracheal tube (ET) may have migrated into the right main bronchus, leading to uneven chest expansion. This can result in inadequate ventilation to the left lung, causing respiratory compromise. The other options, such as blockage of the ET tube by the client's tongue, passage of the ET tube into the esophagus, and infection of the vocal cords, do not directly explain the observed chest wall asymmetry and respiratory distress.

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: 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.
