ATI RN Targeted Medical Surgical Respiratory Questions
Extract:
Question 1 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 2 of 5
A nurse is contributing to the care plan of an older adult client who has pneumonia. Which of the following interventions should the nurse include in the plan?
Correct Answer: A
Rationale: Increased fluid intake thins secretions, aiding clearance in pneumonia. Coughing and deep breathing are helpful but not the primary intervention, and N-95 respirators or full ADL independence are not indicated.
Question 3 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.
Question 4 of 5
Which of the following could the nurse expect to observe in an older adult client who has a pneumothorax?
Correct Answer: A
Rationale: A pneumothorax impairs gas exchange, causing lower oxygen saturations (93%-94%) due to lung collapse. Higher saturations, lower energy use, or increased lung capacity are not expected.
Question 5 of 5
A nurse is reinforcing teaching with a newly licensed nurse about the manifestations of hypoxia. Which of the following findings should the nurse include in the teaching?
Correct Answer: C
Rationale: Hypoxia can cause agitation due to the brain's response to low oxygen levels, signaling distress. Nausea, dysphagia, or warm, dry skin are not typical hypoxia manifestations.
