Review the following ABG lab results below:

pH – 7.48

C02 – 22

HC03 – 22

1. Identify the ABG. Example: Uncompensated Respiratory Alkalosis.
2. develop a brief patient scenario that caused that acid-base imbalance. Focus on the acid-base imbalance not the compensated, uncompensated, fully compensated for the patient scenario. Example: Patient A is so excited to take their first trip overseas that they are hyperventilating with enthusiasm.
3. Create two questions relevant to your ABG or patient scenario. Think: possible electrolyte imbalances associated with this ABG; what assessment findings would you expect; least invasive to invasive treatments…
4. Cite two nursing sources to support responses (ex- Nursing central, Lewis Medical Surgical Nursing book or related, Peer reviewed article, ATI nursing, etc)

ANSWER

ABG Identification

The ABG (Arterial Blood Gas) results indicate Uncompensated Metabolic Alkalosis.

Patient Scenario

Patient B is a 45-year-old woman who was recently diagnosed with chronic gastritis and has been experiencing persistent nausea and vomiting for the past two weeks. She has been taking over-the-counter antacids excessively in an attempt to alleviate her stomach discomfort.

Two Questions Relevant to ABG and Patient Scenario

1. Question 1: What electrolyte imbalances are commonly associated with metabolic alkalosis, and how might they manifest in this patient?

Answer: Metabolic alkalosis is often linked to hypokalemia (low potassium levels) due to excessive loss of potassium through vomiting or the use of certain medications like diuretics. This can lead to muscle weakness, cardiac arrhythmias, and other symptoms. Additionally, hypocalcemia (low calcium levels) may occur, resulting in neuromuscular irritability, such as muscle twitching or spasms.

2. Question 2: What assessments should the nurse perform to evaluate the severity and progression of metabolic alkalosis in this patient?

Answer: The nurse should monitor the patient’s vital signs, especially heart rate and rhythm, as metabolic alkalosis can lead to arrhythmias. Assessing neurological status is essential to detect any changes such as confusion or seizures. Regular assessment of respiratory rate and depth is necessary to determine if the patient is attempting to compensate through hypoventilation. Additionally, the nurse should closely monitor electrolyte levels and urine output to assess for potassium and calcium imbalances.
