## Quiz 11 :Assessment and Care of Patients With Acid-Base Imbalances

The patient is a 21-year-old college student brought to the emergency department by his friends when he was found unconscious during a fraternity party. He was seen drinking heavily at the party and had not eaten for 2 days before the event. He takes no prescription drugs, and his current vital signs are: T = 97.8° F; P = 48, slightly irregular and thready; R = 28, deep and regular; BP = 88/50. His current arterial blood gas results are: pH = 7.31; HCO 3 ? = 25 mEq/L; PaCO 2 = 28 mm Hg; PaO 2 = 99 mm Hg. What specific type of acid-base problem does this patient have? Explain your choice.

A patient is brought unconscious to the emergency ward. He had been drinking heavily at the party but had not eaten for the past 2 days.
His vital signs are:
• Temperature - 97.8 o F
• P - 48
• R - 28
• BP - 88/50
ABG results are:
• pH - 7.31
• HCO 3 - - 25 mEq/l
• PaCO 2 - 28 mm Hg
• PaO 2 - 99 mm Hg
The diagnosis is metabolic acidosis. The decrease in PaCO 2 and the low pH is indicative of metabolic acidosis.

What type of acid-base problem does the nurse expect in a client who is being insufficiently mechanically ventilated and whose most recent arterial blood gas results include a pH of 7.29?

Multiple Choice

For a patient who is insufficiently mechanically ventilated, with the pH of 7.29, the acid base problem the nurse diagnosis is discussed below.
Option A is not correct since it is not metabolic acidosis. The symptoms clearly show mechanical ventilation which indicates that it is respiratory acidosis.
Option B is not correct since it is not metabolic acidosis. The symptoms clearly show mechanical ventilation which indicates that it is respiratory acidosis.
Option C is also not correct since an acid excess leads the low pH indicates underproduction of bicarbonate ions.
Option D is the correct option since the mechanical ventilation indicates respiratory acidosis. Respiratory acidosis with base deficit is seen since the bicarbonate ions are over eliminated.
Hence, the correct option is D. Respiratory acidosis with base deficit.

He was seen drinking heavily at the party and had not eaten for 2 days before the event. He takes no prescription drugs, and his current vital signs are: T = 97.8° F; P = 48, slightly irregular and thready; R = 28, deep and regular; BP = 88/50. His current arterial blood gas results are: pH = 7.31; HCO 3 ? = 25 mEq/L; PaCO 2 = 28 mm Hg; PaO 2 = 99 mm Hg. What is the most probable origin of the acid-base imbalance?

His vital signs are:
• Temperature - 97.8 o F
• P - 48
• R - 28

• pH - 7.31
• HCO 3 - - 25 mEq/l
• PaCO 2 - 28 mm Hg
• PaO 2 - 99 mm Hg
The most probable origin of the acid-base imbalance is the absence of food for 2 days which stimulates excess production of acid.
