Answer:

The body system will shut down.Question 2: What happens when hydrogen ions are released into the blood due to metabolic processes?

Answer:

The blood becomes more acidic.Question 3: Match the buffering system with its response to pH to maintain acid base balanc Takes seconds to attempt correcting acid-base imbalance Intermediate response; takes minutes to correct acid-base imbalance May take days to correct an acid-base imbalance

Answer:

• Chemical buffers
• Respiratory system
• Renal system

Question 4: Which chemical is responsible for adjusting the carbon dioxide gas exhaled to correct an acid-base imbalance?

Answer:

Carbonic acid-bicarbonate Question 5: The nurse is teaching a patient about the general purpose of bicarbonate in the blood. Which patient response evaluated by the nurse indicates correct understanding?

Answer:

"It is a weak base that plays a crucial role in acid-base balance." Question 6: The nurse does an arterial blood gas analysis (ABG) to monitor a patient's pH.Which arterial pH should the nurse interpret as being normal?

Answer:

7.40 Question 7: Which statement should the nurse student include in a presentation regarding the mechanism which rids the body of excess hydrogen ions?

Answer:

"Kidneys excrete hydrogen ions in the urine."

• Respiratory system blows off excess carbon dioxide.

Question 10: Which can occur if the pH of the blood is outside of the normal range?

Answer:

• Serious physiological problems

Answer:

- 7.35

-7.40 Question 12: Which is the primary chemical buffer to correct an acid-base imbalance within a patient's urine?

Answer:

Phosphates

Question 13: Match the venous pH levels with its meaning.

Answer:

-Neutral venous pH -Acidic venous pH -Basic venous pH Question 14: The nurse is providing care to a patient who exercises in excess, leading to acidosis. Which patient statement does the nurse evaluate as accurate related to the cause of the acidosis?

Answer:

"Anaerobic respiration is causing lactic acid to form, leading to acidosis."
