Answer to Question 1

d, a, b, c

a. Second, the nurse provides a well-balanced diet for tissue building and repair. The patient has little hope of resuming baseline functioning without adequate food for fuel and main-taining muscle bulk.
b. Third, to help maintain muscle bulk and joint flexibility, the nurse helps the patient to perform range of motion exercises in preparation for more strenuous physical activity.
c. Finally, before ambulation, the nurse ensures that the patient is up to the chair 4 times a day as progress toward restoring baseline functioning.
d. First, the nurse helps to maintain myocardial oxygenation by keeping the patient's SaO2 above 95 because, if it drops below that level, the arterial blood lacks sufficient oxygen to meet tissue oxygen demands.

Answer to Question 2

D

Feedback
A Incorrect. None of these theories is clearly supported by data.
B Incorrect. Peck's tasks of ego differentiation, body transcendence, and ego tran-scendence demand a great deal of courage and energy that not everyone pos-sesses.
C Incorrect. Tasks of aging in Kelly's model are accepting reality, fulfilling re-sponsibility, and exercising rights.
D Correct. Some persons do not value inner psychological exploration and remain action oriented even in old age, and others are still subject to the same demands of daily living as they were in middle age.
