Following a motor vehicle accident, a client with chest trauma receives a chest tube to relieve a hemothorax. Two hours following the chest tube insertion, the nurse observes the water level in the water-seal chamber is rising during inspiration and falling during expiration. Which action should the nurse implement?

Choice A reason: Pupillary changes to ipsilateral dilation indicate increased intracranial pressure, which is a life-threatening complication of stroke. The nurse should notify the physician and prepare for emergency measures.

Choice B reason: Left-sided facial drooping and dysphagia are common signs of right hemisphere stroke, but they do not require immediate intervention by the nurse. The nurse should monitor the patient's swallowing ability and provide oral care.

Choice C reason: Orientation to person and place only is a sign of impaired cognition, which is also common in right hemisphere stroke. The nurse should assess the patient's memory, judgment, and attention span.

Choice D reason: Unequal bilateral hand grip strengths are a sign of hemiparesis, which is a weakness on one side of the body. The nurse should assist the patient with mobility and prevent contractures.

Choice A reason: This is incorrect because monitoring pulse oximetry every 2 hours is not a sufficient or timely intervention for the nurse to implement. Pulse oximetry is a noninvasive method of measuring the oxygen saturation of hemoglobin in the blood. Normal oxygen saturation is 95% to 100%, while hypoxemia is less than 90%. However, pulse oximetry may not reflect the severity of respiratory distress or the effectiveness of nebulizer treatment in a client with asthma. Moreover, monitoring pulse oximetry every 2 hours is too infrequent for a client who is in acute respiratory distress and needs more frequent assessment and intervention.

Choice B reason: This is incorrect because teaching proper use of a rescue inhaler is not a priority or relevant intervention for the nurse to implement. A rescue inhaler is a type of short-acting bronchodilator that can be used to relieve acute asthma symptoms by relaxing the smooth muscles of the airways and improving airflow. However, teaching proper use of a rescue inhaler is not an urgent action for a client who is already receiving nebulizer treatment, which delivers a higher dose of medication directly to the lungs. Moreover, teaching proper use of a rescue inhaler is not appropriate for a client who is in respiratory distress and may not be able to focus or retain information.

Choice C reason: This is correct because elevating the head of bed to 90 degrees is the most important intervention for the nurse to implement. Elevating the head of bed to 90 degrees can help improve breathing and oxygenation by reducing pressure on the diaphragm and chest wall, increasing lung expansion and ventilation, and facilitating expectoration of mucus. This can enhance the effects of nebulizer treatment and reduce respiratory distress in a client with asthma.

Choice D reason: This is incorrect because determining exposure to asthmatic triggers is not an immediate or helpful intervention for the nurse to implement. Asthmatic triggers are substances or factors that can cause or worsen asthma symptoms by inducing inflammation or constriction of the airways. Examples of asthmatic triggers include allergens, irritants, infections, exercise, stress, or weather changes. However, determining exposure to asthmatic triggers is not a priority action for a client who is in respiratory distress and needs more urgent interventions to improve breathing and oxygenation. Moreover, determining exposure to asthmatic triggers may not change the management or outcome of an acute asthma attack that has already occurred.
