Chapter 6 : Individual and Family Homeostasis, Stress, and Adaptation Questions
Question 1 of 5
Which of the following statements should underlie the nurses care planning for this patient?
Correct Answer: D
Rationale: Transition can contribute to stress, even if the transition is a positive change. The third group of stressors has been studied most extensively and concerns relatively infrequent situations that directly affect people. This category includes the influence of life events such as death, birth, marriage, divorce, and retirement. Counseling is not necessarily indicated.
Question 2 of 5
What is an example of a bodily function that restores homeostasis by negative feedback when conditions shift out of normal range?
Correct Answer: A
Rationale: Negative feedback mechanisms throughout the body monitor the internal environment and restore homeostasis when conditions shift out of normal range. Body temperature, blood pressure, and acid-base balances are examples of functions regulated by these compensatory mechanisms. Blood clotting in the body involves positive feedback mechanisms. Pupil dilation and diuresis are not modulated by negative feedback mechanisms.
Question 3 of 5
What would the nurse tell the patient about dysplastic cells in the bronchi?
Correct Answer: B
Rationale: Dysplasia is bizarre cell growth resulting in cells that differ in size, shape, or arrangement from other cells of the same tissue type. Dysplastic cells have a tendency to become malignant; dysplasia is seen commonly in epithelial cells in the bronchi of people who smoke. This may not be a harmless condition and dysplasia does not cause scar tissue. Hyperplasia is an increase in the number of new cells.
Question 4 of 5
What pathophysiological process has occurred as a result of the submersion?
Correct Answer: C
Rationale: The length of time different tissues can survive without oxygen varies. The brain will become hypoxic in 3 to 6 minutes. The other options are incorrect because submersion injuries do not cause atrophy to brain cells right away; submersion injuries also do not cause cellular lysis or necrosis to the brain.
Question 5 of 5
You should be aware that the oxygen demands of the patients body would change in which direction and why?
Correct Answer: A
Rationale: When a persons temperature is elevated, hypermetabolism occurs, and the respiratory rate, heart rate, and basal metabolic rate increase. The other options are incorrect because oxygen demands would not decrease and they would not increase due to a decrease in metabolism.
