NURS 2873 Exam 3 Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) The nurse is assessing a patient who has diabetic ketoacidosis. Her assessment reveals tachycardia, lethargy, and hyperventilation. Treatment for the ketoacidosis has been initiated. What should the nurse do about the hypoventilation?

• Request an order for pain medication and oxygen at 6

L/min

• Lubricate the patient's lips and allow continued

hyperventilation

• Have the patient breathe into a paper bag to stop

hyperventilating

• Contact the physician immediately regarding this

complication - Correct Answers ✅3 Hyperventilation is a compensatory response to metabolic acidosis and should be allowed to continue because it helps move the blood pH toward the normal range. Lubricating the lips is a supportive nursing intervention that prevents drying and cracking of the lips during hyperventilation.A patient is having her first severe, acute asthma episode. It began 2 hours ago. What blood gas values should the nurse expect to see?

• pH high, PaCO2 high, HCO3- high
• pH low, PaCO2 low, HCO3- low
• pH low, PaCO2 high, HCO3- high 1 / 4

• pH low, PaCO2 high, HCO3- normal - Correct Answers

✅4 A severe acute asthma episode impairs the excretion of carbonic acid, causing respiratory acidosis with a high PaCO2 and a low pH. Renal compensation takes longer than 2 hours to occur, so the respiratory acidosis is uncompensated, leaving the HCO3- normal.Which diagnosis indicates that the nurse should assess the patient most carefully for development of metabolic acidosis?

• Type B COPD and pneumonia
• Acute meningococcal meningitis
• A pancreatic fistula that is draining
• Severe hyperaldosteronism - Correct Answers ✅3

The pancreas secretes bicarbonate; a draining pancreatic fistula could cause metabolic acidosis from bicarbonate loss.The patient has severe metabolic alkalosis. Which intervention has the highest priority?

• Raise the side rails on the patient's bed
• Measure the urine output and skin turgor
• Teach the family about metabolic alkalosis 2 / 4

• Administer IV NaHCO3 as ordered - Correct Answers ✅1

Severe metabolic alkalosis causes a decreased level of consciousness; raising the side rails is a safety intervention in that situation. Safety interventions are a higher priority than teaching.The nurse in the emergency department is caring for a patient who is on a ventilator. The patient's blood gases report reveals a pH 7.48, PaO2 85, a PaCO2 32, and a HCO3

• What is the nurse's interpretation of these results?
• Metabolic acidosis
• Metabolic alkalosis
• Respiratory acidosis
• Respiratory alkalosis - Correct Answers ✅4

The nurse is caring for a patient who suddenly becomes lethargic and has an increase in the depth and rate of

respirations following ABG results: pH 7.32, PaO2 88, PaCO2

37, and HCO3 16. How should the nurse interpret these results?

• Metabolic acidosis
• Metabolic alkalosis
• Respiratory acidosis
• Respiratory alkalosis - Correct Answers ✅1 3 / 4

NURS 2873 Exam 3 Questions and Verified Answers, 100% Guarantee Pass (Latest 2025) A patient is admitted to the ED with dehydration. ABG results reveal that the patient has metabolic acidosis. Which of the following signs or symptoms is the most likely cause of this imbalance?

• Hypoventilation
• Vomiting and diarrhea
• Serum potassium is 5.1
• Arterial oxygen saturation is 91% - Correct Answers ✅2

Vomiting and diarrhea cause too much acid, the buffers have been overwhelmed, and body fluids have too much acid. Acid excretion is not able to keep up with acid production or intake.The nurse should ask which of the following questions to detect the risk factors for metabolic acidosis?(Select all that apply.)

• Have you been vomiting today?
• When did your kidneys stop working?
• How long have you had diarrhea?
• Are you still feeling short of breath?
• What type of antacid did you take?
