1. Acid-base balance occurs when the pH level of the blood is between:
a. 7.3 and 7.5
b. 7.35 and 7.45
c. 7.4 and 7.5
d. 7.25 and 7.35
ANS: B
Acid-base balance is the maintenance of arterial blood pH between 7.35 and 7.45 through hydrogen ion
production and elimination.
2. The nurse would expect a patient with respiratory acidosis to have an excessive amount of
a. Hydrogen ions.
b. Bicarbonate.
c. Oxygen.
d. Phosphate.
ANS: A
Respiratory acidosis occurs when the arterial blood pH level falls below 7.35 and is caused by either too many
hydrogen ions in the body (respiratory acidosis) or too little bicarbonate (metabolic acidosis). Excessive
oxygen and phosphate are not characteristic of respiratory acidosis.
3. The best way for an individual to maintain acid-base balance is to
a. avoid or quit smoking.
b. exercise regularly.
c. eat healthy and well-balanced meals.
d. All of the above.
ANS: D
Maintaining a healthy lifestyle is the best way to maintain acid-base balance. For example, most cases of
COPD can be prevented by avoiding or quitting smoking, while regular exercise and a healthy diet can
decrease the incidence of type-2 diabetes.
4. The process to control cellular growth, replication, and differentiation to maintain homeostasis is called:
a. cellular regulation.
b. cellular impairment.
c. cellular reproduction.
d. cellular tumor.
ANS: A
Cellular Regulation is the term used to describe both the positive and negative aspects of cellular function
