The nurse is caring for a patient in the critical care area whose fluid volume status needs to be assessed closely. The nurse would expect which type of monitoring to be used?
1. Arterial pressure monitoring
2. Pulmonary artery pressure monitoring
3. Central venous pressure monitoring
4. Intra-aortic balloon pump monitoring
3
Rationale 1: Arterial pressure monitoring would not measure central venous pressure, which is essential for monitoring fluid volume status.
Rationale 2: Fluid volume can be monitored effectively with equipment that is less invasive than a pulmonary artery pressure monitor.
Rationale 3: Central venous pressure (CVP) monitoring can be accomplished with a central IV line and an IV pump or a monitoring system. It would be the least complicated method to monitor fluid status.
Rationale 4: An intra-aortic balloon pump would not be used for pressure monitoring.

A client asks the nurse why lung cancers are less sensitive to antineoplastic agents. Which response should the nurse provide the client?
A. "Lung cancer cells have a very erratic cell cycle, and this is why there isn't much difference between the number of replicating and resting cells." B. "Lung cancer cells have been growing for a long time before detection, so they are less sensitive to antineoplastic agents." C. "Lung cancer cells have a low growth fraction, which means there isn't much difference between the number of replicating and resting cells." D. "Lung cancer cells grow in a high-oxygen environment, so they are not very sensitive to antineoplastic agents."
A spouse of a patient recovering from a head injury asks why the patient easily agitated, impulsive, and cannot focus. Which response should the nurse make?
1. "The injuries may have damaged the prefrontal cortex of the brain, causing these symptoms." 2. "The injuries may have damaged the occipital lobe of the brain, causing these symptoms." 3. "The injuries may have damaged the parietal lobe of the brain, causing these symptoms." 4. "The injuries may have damaged the cerebellum of the brain, causing these symptoms."
