Correct Answer: A

Rationale: A stroke affecting the right cerebral hemisphere can lead to poor impulse control due to the involvement of this area in regulating behavior and inhibiting impulses. Deficits in the right visual field are associated with stroke affecting the left cerebral hemisphere. Inability to discriminate words and letters may be seen in left cerebral hemisphere strokes. Motor retardation may be observed with strokes affecting motor areas in either hemisphere but is not the most specific finding related to a right cerebral hemisphere stroke.

Correct Answer: C

Rationale: Ventilator-associated pneumonia (VAP) is a common complication in clients receiving mechanical ventilation. Oral hygiene is crucial in reducing the risk of VAP. Brushing the client's teeth with a suction toothbrush every 12 hours helps prevent bacterial colonization in the oral cavity, which can be aspirated into the lungs. Positioning the head of the bed flat can increase the risk of aspiration. Turning the client every 4 hours is important for preventing pressure ulcers but not directly related to reducing VAP. Providing humidity in the ventilator tubing helps maintain airway moisture but does not directly address the risk of VAP.

Correct Answer: B

Rationale: When a client is positioned on the left side in Trendelenburg position for pulmonary hygiene, secretions are expected to be mobilized from the lateral segment of the right lower lobe. This positioning helps facilitate drainage and clearance of secretions from this specific area of the lung, aiding in overall pulmonary hygiene and improving ventilation.

Correct Answer: A

Rationale: In a client with a three-chamber closed chest tube system, a rise in the water seal chamber with client inspiration is an expected finding. The nurse should continue to monitor the client as this indicates that the system is functioning correctly. There is no need to notify the healthcare provider, reposition the client, or clamp the chest tube as these actions are not indicated in response to a rise in the water seal chamber.

Correct Answer: D

Rationale: Following a colon resection surgery, it is essential to support the incision site to reduce the risk of respiratory complications. Splinting the incision helps to minimize pain during coughing, aiding in effective clearing of secretions and preventing respiratory problems. This intervention supports the client's respiratory function postoperatively, promoting optimal recovery.
