Questions Correctly Answered and
Graded A+ | Latest 2024/2025 Guide
What is acidosis? - Correct Answer - excessive hydrogen ions (H+),
decrease in serum pH
What is alkalosis? - Correct Answer - deficit of hydrogen ions (H+),
increase in serum pH
Acid-Base Imbalance - Correct Answer - -Respiratory system can alter
carbonic acid (CO2) levels to change pH
-Kidneys can modify the excretion rate of acids and adsorption of
bicarbonate ions to regulate pH (most effective but slow)
-Life-threatening and needs to be fixed
-only works short term
(H2CO3: H20-Kidneys CO2 lungs)
Decompensation - Correct Answer - -Requires intervention to maintain
homeostasis
-Life-threatening
What is Respiratory Acidosis? - Correct Answer - -Increase carbon
dioxide levels
-Too much acid (hypoventilating) leading to an increase in CO2
,What are causes of Respiratory Acidosis? - Correct Answer - -Airway
obstruction
-Pulmonary disease, COPD, drugs

What is the first line of defense of the body from injury? - Correct Answer
- -mechanical barrier: unbroken skin and mucous membranes,
secretions such as tears and gastric juices (nonspecific)
What is the second line of defense of the body from injury? - Correct
Answer - -Phagocytosis (WBC engulf cell debris/bacteria)
-Inflammation (nonspecific)
What is the third line of defense of the body from injury? - Correct
Answer - -Production of specific antibodies or cell-mediated immunity
