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: 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: C

Rationale: In the scenario of a pulmonary embolism, the priority medication to administer is Heparin. Heparin is an anticoagulant that helps prevent the formation of new blood clots and the growth of existing ones, which is crucial in managing pulmonary embolism. Furosemide is a diuretic used to treat fluid retention, Dexamethasone is a corticosteroid used for inflammation, and Atropine is an anticholinergic medication used for various purposes such as treating bradycardia.

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.
