Due to complications, a male postoperative patient has been unable to mobilize secretions for several days following surgery and develops atelectasis. Which of the following processes would his care team anticipate with relation to his health problem?
A)
Vasodilation in the alveolar vessels in the affected region of his lung
B)
Increased workload for the left side of the patient's heart
C)
Increased blood flow to the area of atelectasis
D)
Directing blood flow away from the lung regions that are hypoxic
Ans:
D
Feedback:
Regional hypoxia, such as with a diagnosis of atelectasis, is associated with vasoconstriction and redirection of blood away from, not toward, the affected area of the lung. This also contributes to an increased workload for the right side of the heart.
