Test your Knowledge
Welcome to the NBCRNA’s Question of the Week page. The question of the week (QOTW) serves as an extension of the NBCRNA’s CPCA Practice and allows for CRNA’s to become familiar with question types and content while testing their knowledge. Each week a new question will be posted on Facebook and Twitter, with the answer(s) and rationale provided here. Be sure to follow NBCRNA on social media and never miss a question!
How did you do on this week's QOTW?
Answers: A, B
Rationale: Atelectasis occurs under general anesthesia because of absence of negative pressure due to diaphragmatic contraction, compression of lung tissue, altered surfactant, and increased oxygen absorption. High tidal volumes also contribute to atelectasis. Lower tidal volumes with the addition of PEEP and reduced FiO2 is recommended to reduce the risk of atelectasis.
