Answer to Question 1
A
Nursing interventions in the postoperative period are focused first on promoting ventilation, adequate oxygenation, and preventing complications such as atelectasis and pneumonia. Adequate analgesia is necessary to promote the mobility of the patient and decrease pulmonary complications. Early ambulation is encouraged to reduce the risk of pulmonary embolus. Infection prevention with hand hygiene and antibiotics is important as well.
Answer to Question 2
A
A waves are the most clinically significant of the three types. They usually occur in an already elevated baseline intracranial pressure (ICP) (>20 mm Hg) and are characterized by sharp increases in ICP of 30 to 69 mm Hg, which plateau for 2 to 20 minutes and then return to baseline. B waves appear to reflect fluctuations in cerebral blood. C waves are small, rhythmic waves that occur every 4 to 8 minutes at normal levels of ICP. They are related to normal fluctuations in respiration and systemic arterial pressure.
