Question 1: The nurse is caring for a client with renal failure experiencing shortness of
(see full question)
breath and increased respiratory rate. The arterial blood gas reflects a pH of
7.10 and a HCO3 level of 18 mEq/L. How does the nurse interpret these
findings?

You selected: Metabolic acidosis

Correct

Explanation: Metabolic acidosis would be diagnosed based on the findings related to a low
pH level and a low bicarbonate level. The other conditions would not result
from the findings provided ..... (more)

Question 2: When interpreting the arterial blood gas, the nurse recognizes which of these
(see full question) reflects the value for bicarbonate?

You selected: HCO3-

Correct

Explanation: Bicarbonate is abbreviated as HCO3. H2CO3 is the abbreviation for carbonic
acid, HCl is the abbreviation for hydrochloric acid, and H+ is the abbreviation
for hydrogen ..... (more)

Question 3: A client's most recent laboratory results suggest the presence of metabolic
(see full question) alkalosis. What action by the nurse best addresses a potential cause of this
acid-base imbalance?

You selected: Administering an antiemetic to treat the client's frequent vomiting

Correct

Explanation: Vomiting results in the loss of hydrogen ions, potentially resulting in metabolic
alkalosis. Constipation and skin breakdown are not among the most common
causes of metabolic alka ... (more)

Question 4: The nurse recognizes the role of the lungs in acid-base balance is regulation
(see full question) of which of the following?

You selected: CO2

Correct




Question 5: A client has these arterial blood gas values: anion gap 20 mEq/L, pH 7.29,
(see full question) pCO2 37mm Hg, HCO3- 11 mEq/L, base excess -6 mEq/L. With what
condition do these values correspond?

You selected: Lactic acidosis

Correct

Explanation: Anion gap (AG) is the difference between the plasma concentration of sodium
ions and the sum of the measured anions (chloride and bicarbonate).
Normally, the AG value should be bet ... (more)

pH: 7.24
PCO2: 38 mm Hg
HCO3:18 mEq/L
The nurse would interpret this as:

You selected: Metabolic alkalosis

Incorrect

Correct response: Metabolic acidosis

Explanation: Metabolic acidosis would be diagnosed based on the findings related to a low
pH level ( ... (more)

Question 7: What is the nurse’s expectation about a client’s ability to compensate for a
(see full question) metabolic blood gas disorder?

You selected: The client will compensate with the respiratory system.

Correct

Explanation: The one thing that a nurse can expect is that a client with a metabolic disorder
will compensate with the respiratory system. The client cannot compensate
with the same system. The ... (more)

Question 8: A client with ethylene glycol toxicity is restless, and stating he has flank pain.
(see full question) What intervention should the nurse perform to minimize complications?

You selected: Increase IV fluids
