ATI RN Targeted Medical Surgical Respiratory Questions
Extract:
Question 1 of 5
A patient has a diagnosis of Impaired Gas Exchange. Which assessment finding shows that the interventions have been effective?
Correct Answer: A
Rationale: An SpO2 of 97% on 2L nasal cannula indicates effective oxygenation, directly reflecting improved gas exchange. Comfort, sputum production, or mobility are less specific indicators.
Question 2 of 5
A nurse is reviewing the laboratory results of a client who is postoperative and has a respiratory rate of 7/min. The arterial blood gas (ABG) values include: pH 7.22 PaCO2 68 mm Hg Base excess -2 PaO2 78 mm Hg Oxygen saturation 80% Bicarbonate 28 mEq/L. Which of the following interpretations of the ABG values should the nurse make?
Correct Answer: B
Rationale: The low pH (7.22) and elevated PaCO2 (68 mm Hg) indicate respiratory acidosis, as the accumulation of carbon dioxide lowers the blood pH. The bicarbonate level is slightly elevated, suggesting partial compensation, but not indicative of metabolic alkalosis or acidosis.
Question 3 of 5
What nursing intervention enhances the nutritional status of a patient with COPD?
Correct Answer: A
Rationale: Small, frequent meals reduce dyspnea and gastric distension, improving nutritional intake in COPD. Extra liquids, pre-meal exercise, or information alone are less effective.
Question 4 of 5
A nurse is assisting with the care of a client who is postoperative following a pneumonectomy. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: Splinting the incision during coughing reduces pain and supports healing post-pneumonectomy, minimizing complications like wound dehiscence.
Question 5 of 5
A nurse is caring for a client who has been admitted with asthma exacerbation and is experiencing increased wheezing and has an oxygen saturation of 91%. The client is scheduled for his next breathing treatment in 1hr. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: Albuterol, a bronchodilator, rapidly relieves bronchospasm and wheezing in asthma exacerbations, improving airflow and oxygenation. Other options do not address the acute symptoms effectively.
