Answer to Question 1
ANS: A, C, D, E
Risk for asphyxiation related to inspissated oral and nasopharyngeal secretions is caused by poor oral hygiene. Clients at risk include those with altered mental status and level of consciousness (traumatic brain injury), dehydration, an inability to communicate (aphasic) and cough effectively (quadriplegic), and a risk of aspiration (aspiration precautions). The client with a fractured femur is at risk for a pulmonary embolism.
Answer to Question 2
ANS: D
Tachycardia can indicate hypoxemia as the body tries to circulate the oxygen that is available. A barrel chest is not an emergency finding. Likewise, a pulse oximetry level of 92 is not considered an acute finding. The expiratory phase is expected to be longer than the inspiratory phase in someone with airflow limitation.
