NR 462 Exam 2 Acid-base,
Pain, IV 2026 Exam Questions
and Answers | Already Graded
A+
What is true when considering Acid-Base Balance? - ANSWER ✔✔-
The body normally maintains a steady balance.
- Acidity or alkalinity of a solution depends on its hydrogen in (H+)
concentration.
- The ratio between acid:base is 1:20
What three systems work together to maintain this acid-base balance? -
ANSWER ✔✔Buffer system
, Respiratory system
Renal system
Buffering system - ANSWER ✔✔Act by chemically changing strong
acids into weaker ones or bind to neutralize them.
carbonic acid-bicarbonate system - ANSWER ✔✔A system that
regulate pH by using H2CO3 and HCO3 to donate or accept a H+ ion, in
order to maintain a normal blood pH
Phosphate buffer system - ANSWER ✔✔Consists of dihydrogen
phosphate ions as the hydrogen ion donor (acid) and hydrogen
phosphate ion as the ion acceptor (base). The movement of H+ions
helps maintain blood pH.
Protein buffer system - ANSWER ✔✔Intracellular and extracellular
process of using amino acids to accept or release H+ ions to maintain
blood pH
Hemoglobin buffer system - ANSWER ✔✔Use of
carbaminohemoglobin in the venous circulation to buffer blood pH
Normal Arterial Blood Gas Values: - ANSWER ✔✔7.35-7.45pH
Normal PaCO2 Values: - ANSWER ✔✔35-45 mmHg
