A nurse is caring for a client who has metabolic alkalosis. For which of the following clinical manifestations should the nurse monitor? (Select all that apply.).
A.
Lethargy.
B.
Kussmaul’s respirations.
C.
Circumoral paresthesia.
D.
Bicarbonate excess.
E.
Flushing
The Correct Answer and Explanation is:
In metabolic alkalosis, monitoring for specific clinical manifestations is crucial to effectively manage the condition and provide appropriate care. The correct answers are:
A. Lethargy.
C. Circumoral paresthesia.
D. Bicarbonate excess.
Here’s a detailed explanation for each correct option:
Lethargy: Metabolic alkalosis can lead to a decrease in cerebral blood flow due to changes in blood pH, which might manifest as lethargy or confusion. This is because an elevated blood pH increases the binding of calcium to proteins, leading to hypocalcemia (low calcium levels), which affects neuromuscular function and can cause symptoms such as fatigue and lethargy.
Circumoral Paresthesia: This symptom is commonly associated with hypocalcemia, which is a common consequence of metabolic alkalosis. When the blood pH rises, it increases the binding of calcium to proteins, resulting in a decrease in the level of free (ionized) calcium in the blood. This reduced ionized calcium can cause sensations of tingling or numbness around the mouth, known as circumoral paresthesia.
Bicarbonate Excess: In metabolic alkalosis, there is an excess of bicarbonate in the blood. This condition is characterized by a higher than normal pH level due to an increase in bicarbonate or a loss of hydrogen ions. Monitoring bicarbonate levels is essential in confirming the diagnosis of metabolic alkalosis and guiding appropriate treatment.
The other options are less characteristic of metabolic alkalosis:
B. Kussmaul’s Respirations: These are deep, labored breaths typically associated with metabolic acidosis, not alkalosis. Kussmaul’s respirations are the body’s attempt to compensate for acidosis by expelling more carbon dioxide.
E. Flushing: Flushing is not a typical manifestation of metabolic alkalosis. It is more often associated with conditions like fever or vasodilation, and is not directly related to changes in blood pH in metabolic alkalosis.
In summary, when monitoring a patient with metabolic alkalosis, it’s important to look out for signs like lethargy, circumoral paresthesia, and bicarbonate excess to manage the condition effectively.
