CORRECT 100% VERIFIED ANSWERS ALREADY RATED
A+ (2025 NEWEST!!!)
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? -
CORRECT Normal pH on arterial blood gases
What is one of the causes of acidosis? - CORRECT Kidney failure
Lab results for a 62-year-old patient show the following results: pH 7.48; bicarbonate 26;
PaO 2 90; PaCO 2 32. These findings are consistent with which acid-base imbalance? -
CORRECT respiratory alkalosis
To decrease the risk of acid-base imbalance, what goal must the patient with diabetes mellitus
strive for? - CORRECT Maintaining blood glucose level within normal limits.
How does the body compensate for a low pH? - CORRECT 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? - CORRECT Hypokalemia
Which arterial blood gas laboratory values would be seen in metabolic alkalosis? -
CORRECT 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? - CORRECT 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? -
CORRECT Respiratory acidosis
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? - CORRECT Respiratory
alkalosis
, Page |2
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? - CORRECT
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? - CORRECT
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? - CORRECT 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? - CORRECT
Respiratory compensation for metabolic acidosis
Deep and rapid breaths consistent with Kussmaul respirations are found in patients with
which type of acid-base imbalance? - CORRECT Metabolic acidosis
Which conditions place a patient at risk for developing metabolic alkalosis? Select all that
apply. - CORRECT blood transfusion
nasogastric suctioning
total parenteral nutrition
What is taking place in the body when hyperventilation occurs? - CORRECT 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? - CORRECT 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. - CORRECT numbness
around the mouth
hyperactivity of deep tendon reflexes
, Page |3
The nurse obtains lab results for a 50-year-old patient with the following results: pH 7.24;
bicarbonate 20; PaO 2 82; PaCO 2 35. These findings are consistent with which acid-base
imbalance? - CORRECT Metabolic acidosis
The lab values for a patient admitted for an exacerbation of chronic obstructive pulmonary
disease (COPD) reveal a pH of 7.29 with a decreased PaO 2 and an elevated PaCO 2. Which
initial treatment does the nurse expect the provider to most likely order? - CORRECT
Bronchodilator therapy
The nurse is assessing the laboratory reports of a patient with impaired kidney function. What
changes most indicate the patient has metabolic acidosis? - CORRECT Decrease in
serum bicarbonate level
When caring for a group of patients at risk for respiratory acidosis, the nurse identifies which
person as at highest risk? - CORRECT Patient who smokes cigarettes
A patient admitted to the emergency department is having an acute episode of asthmatic
bronchitis. The nurse notes the pH on the most recent arterial blood gas is 7.31. What is the
most likely explanation for this finding? - CORRECT Acidosis in response to the
excessive retention of carbon dioxide
A new nurse is caring for a postoperative patient with the following arterial blood gas (ABG)
result: pH 7.30; PaCO 2 60 mm Hg; PaO 2 80 mm Hg; bicarbonate 24 mEq/L; and O 2
saturation 96%. Which of these actions by the new graduate is indicated? - CORRECT
Encourage the patient to use the incentive spirometer and cough.
Which arterial blood gas result does the nurse anticipate in the care of a patient diagnosed
with acute kidney failure? - CORRECT pH 7.33, PaO 2 82 mm Hg, PaCO 2 35 mm
Hg, HCO 3 - 19 mEq/L
Which action does the nurse take first for the patient who is admitted to the emergency
department (ED) with a panic attack and whose blood gases indicate respiratory alkalosis? -
CORRECT Encourage the patient to take slow breaths.
A patient currently taking acetazolamide develops metabolic acidosis. Which nursing
interventions are appropriate for the nurse to include in the plan of care? Select all that apply.
- CORRECT Monitoring electrolyte levels
