ATI RN Adult Medical Surgical Online Practice 2023 A

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: D

Rationale: When a client expresses being short of breath, it may indicate a serious condition requiring immediate attention to ensure adequate oxygenation. This client should be seen first to assess the severity of the situation and initiate appropriate interventions. The other options, such as awaiting transport for an x-ray, having a prescription for discharge, or receiving oral pain medication 30 minutes ago, do not present immediate life-threatening concerns compared to a client experiencing shortness of breath.

Correct Answer: A

Rationale: The client's shallow respirations at 9/min indicate hypoventilation, leading to an accumulation of carbon dioxide in the blood, causing respiratory acidosis. In this scenario, the client is at risk for developing respiratory acidosis due to inadequate ventilation and subsequent CO2 retention.

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
