A nurse teaches a patient about atelectasis. Which statement by the patient indicates an understanding of atelectasis?
"Atelectasis affects only those with chronic conditions such as emphysema."
"Hyperventilation will open up my alveoli, preventing atelectasis."
"It is important to do breathing exercises every hour to prevent atelectasis."
"If I develop atelectasis, I will need a chest tube to drain excess fluid."
The Correct Answer is C
A. Atelectasis can occur in anyone, not just those with chronic conditions; this statement is incorrect.
B. While hyperventilation may temporarily open alveoli, it is not a preventative measure for atelectasis.
C. Breathing exercises, such as incentive spirometry or deep breathing, are effective in preventing atelectasis by promoting lung expansion and alveolar ventilation.
D. A chest tube is typically used to remove air or fluid from the pleural space, not for the treatment of atelectasis, which is often managed with respiratory therapies.

Correct Answer is D
Explanation
A. Sequential compression devices are used to prevent deep vein thrombosis and are not relevant for assessing orthostatic hypotension.
B. Elastic stockings are used to promote venous return and prevent edema, not for measuring blood pressure.
C. A thermometer measures body temperature and does not provide information on blood pressure or orthostatic changes.
D. A blood pressure cuff is essential for assessing orthostatic hypotension. The nurse will measure blood pressure while the patient is supine, sitting, and standing to determine any significant changes that occur with position changes.
Correct Answer is A
Explanation
A. This observation indicates proper body alignment as the arms hanging comfortably at the sides suggest relaxation and good posture.
B. The edge of the seat should not be in contact with the popliteal space; there should be a small gap to prevent pressure and improve circulation.
C. While the feet should be supported on the floor, they should be flat rather than flexed at the ankles for optimal alignment.
D. The body weight should be distributed between the buttocks and thighs, not just on the buttocks, to promote comfort and good posture.
