NUR 2243 Module 1 EAQs
- When evaluating the laboratory results of a patient with diabetic ketoacidosis , which lab
value indicates the body has fully compensated from this acid-base imbalance?
Answer
Normal pH on arterial blood gases
- What is one of the causes of acidosis?
Answer
Kidney failure
- Lab results for a 62-year-old patient show the following results
Answer
pH 7.48; bicarbonate 26; PaO 2 90; PaCO 2 32.These findings are consistent with which acid- base imbalance?
respiratory alkalosis
- To decrease the risk of acid-base imbalance, what goal must the patient with diabetes mellitus
strive for?
Answer
Maintaining blood glucose level within normal limits.
- How does the body compensate for a low pH? 1 / 4
Answer
Increases respiratory rate
- A patient admitted with diabetic ketoacidosis was treated for metabolic acidosis with
intravenous (IV) fluids and insulin. Which electrolyte imbalance does the nurse monitor for as the acid-base imbalance resolves?
Answer
Hypokalemia
- Which arterial blood gas laboratory values would be seen in metabolic alkalosis?
Answer
pH 7.49, HCO 3 - 32
- When caring for a patient with metabolic acidosis, what must the nurse keep in mind regarding
acid-base chemistry?
Answer
Fluids with lower pH have higher acidity.
- A lab report for a 47-year-old patient shows the following results
pH 7.32; bicarbonate 24; PaO 2 77; PaCO 2 48.These findings are consistent with which acid- base imbalance?
Answer
Respiratory acidosis 2 / 4
- After a motor vehicle crash, the nurse is consoling a patient in the emergency department
who is hysterical and hyperventilating after being notified of the death of a family member.What acid-base imbalance is this patient likely to develop?
Answer
Respiratory alkalosis
- A patient is admitted with severe diabetic ketoacidosis. Arterial blood gas results reveal a
pH of 7.21. What is this patient's acidosis most likely in response to?
Answer
Excessive breakdown of fatty acids
- When caring for a patient with kidney failure who has metabolic acidosis, which symptom
does the nurse expect as evidence of the body's compensatory effort?
Answer
Rapid and deep respirations
- The nurse is caring for a group of patients with acidosis. The nurse recognizes that
Kussmaul respirations are consistent with which situation?
Answer
Aspirin overdose
- A patient with diabetes mellitus is brought to the emergency department after vomiting for
several days. The patient has rapid, deep respirations and a urine dipstick reveals ketonuria.Which process does the nurse suspect is occurring with this patient?
Answer
Respiratory compensation for metabolic acidosis 3 / 4
- Deep and rapid breaths consistent with Kussmaul respirations are found in patients with
which type of acid-base imbalance?
Answer
Metabolic acidosis
- Which conditions place a patient at risk for developing metabolic alkalosis? Select all
that apply.
Answer
blood transfusion
nasogastric suctioning total parenteral nutrition
- What is taking place in the body when hyperventilation occurs?
Answer
The central nervous system is responding to a rise in carbon dioxide.
- Which electrolyte abnormality does the nurse anticipate when reviewing laboratory data
for a patient admitted with metabolic acidosis?
Answer
Hyperkalemia
- The nurse is caring for a patient with metabolic alkalosis. What manifestations of
metabolic alkalosis is the nurse likely to assess? Select all that apply.
