A nurse is caring for a client who has metabolic acidosis due to diabetic ketoacidosis (DKA) Which of the following manifestations should the nurse monitor?
A.
Kussmaul respirations.
B.
Bradypnea.
C.
Muscle spasms.
D.
Numbness and tingling of extremities.
The correct answer and Explanation is :
The correct answer is A. Kussmaul respirations.
Explanation
Metabolic acidosis, particularly in the context of diabetic ketoacidosis (DKA), presents with several physiological manifestations. Kussmaul respirations are a significant indicator of the body’s attempt to compensate for acidosis by increasing the rate and depth of breathing. This respiratory pattern occurs due to the body’s effort to expel carbon dioxide (CO2) to mitigate the acidosis, thereby increasing blood pH towards normal levels.
In DKA, the accumulation of ketones in the blood leads to a decrease in pH, resulting in acidosis. The body responds to this acidic environment by hyperventilating, which is characteristic of Kussmaul respirations. This compensatory mechanism is vital for nurses to monitor, as changes in respiratory patterns can indicate the severity of the acidosis and the effectiveness of treatment.
Options B, C, and D are less specific to metabolic acidosis due to DKA.
- B. Bradypnea is a slowed breathing rate, which is not typical in metabolic acidosis. Instead, patients often exhibit tachypnea or rapid breathing as a compensatory response.
- C. Muscle spasms may occur in different contexts, such as electrolyte imbalances (e.g., hypocalcemia) but are not a direct manifestation of metabolic acidosis.
- D. Numbness and tingling of extremities can be associated with various conditions, including hyperventilation or electrolyte imbalances but are not specific indicators of DKA or metabolic acidosis.
Monitoring Kussmaul respirations is crucial in managing DKA, as it provides insight into the patient’s respiratory compensation and overall metabolic state. Early recognition of these manifestations can lead to timely interventions, improving patient outcomes in acute care settings.
