client?
b
A) Metabolic acidosis b

C) Metabolic alkalosis b
D) Respiratoryacidosis b
Answer: A

Explanation: A) A client who is fasting is at risk for development of metabolic acidosis. The body
b b b b b b b b b b b b b b b b
recognizes fasting as starvation and begins to metabolize its own fatty acids into ketones, which are
b b b b b b b b b b b b b b b b
metabolic acids.

2) The nurse is caring for a client in the emergency department. Which factors will the nurse

identify that increase the client's risk for metabolic acidosis? Select all that apply.

A) Abdominal fistulas b

D) Chronic renal failure b b
E) Hypovolemicshock b
Answer: A, D, E
b b b b
Explanation: A) Metabolic acidosis is rarely a primary disorder. It usually develops during the
b b b b b b b b b b b b b
course of another condition such as an abdominal fistula which can cause the loss of bicarbonate from
b b b b b b b b b b b b b b b b b
the intestine.
b b
B) Chronic obstructive pulmonary disease places the client at risk for respiratory acidosis with the
b b b b b b b b b b b b b
increased retention of carbon dioxide in the blood.
b b b b b b b b
C) Pneumonia places the client at risk for respiratory acidosis with the increased retention of

carbon dioxide in the blood.
b b b b b
D) Metabolic acidosis is rarely a primary disorder. It usually develops during the course of another
b b b b b b b b b b b b b b
condition such as chronic renal failure. In this health problem, the kidneys are unable to excrete a
b b b b b b b b b b b b b b b b b
normal amount of hydrogen ions in the urine. This results in an excessive amount of hydrogen ions
b b b b b b b b b b b b b b b b b
in the blood, which produces metabolic acidosis.
b b b b b b b
E) Metabolic acidosis is rarely a primary disorder. It usually develops during the course of another
b b b b b b b b b b b b b b
condition such as hypovolemic shock. With a severe blood loss, there is a lack of blood flow
b b b b b b b b b b b b b b b b b
throughout the body and a lack of oxygen in every cell. Adenosine triphosphate (ATP) must produce
b b b b b b b b b b b b b b b b
energy anaerobically without the presence of oxygen; lactic acid is a by-product. This produces
b b b b b b b b b b b b b b
systemic lactic acidosis, a type of metabolic acidosis.
