During the performance of a Romberg test, the nurse observes the client sway slightly. What action should the nurse take?

Choice A rationale:
Respiratory acidosis is characterized by a low pH (less than 7.35), a high PaCO2 (greater than 45 mm Hg), and a normal or high HCO3 (22-26 mEq/L). It occurs when there is a buildup of carbon dioxide in the blood due to impaired ventilation.
The patient's ABGs do not align with respiratory acidosis because the pH is elevated (7.6), and the PaCO2 is within the normal range (40 mm Hg).
Choice B rationale:
Respiratory alkalosis is characterized by a high pH (greater than 7.45), a low PaCO2 (less than 35 mm Hg), and a normal or low HCO3 (22-26 mEq/L). It occurs when there is excessive loss of carbon dioxide through hyperventilation.
The patient's ABGs do not align with respiratory alkalosis because the HCO3 is elevated (32 mEq/L), which is not typical for this condition.
Choice C rationale:
Metabolic acidosis is characterized by a low pH (less than 7.35), a normal or low PaCO2 (less than 40 mm Hg), and a low HCO3 (less than 22 mEq/L). It occurs when there is an excess of acid in the body or a loss of bicarbonate.
The patient's ABGs do not align with metabolic acidosis because the pH is elevated (7.6), and the HCO3 is elevated (32 mEq/L).
Choice D rationale:

Metabolic alkalosis is characterized by a high pH (greater than 7.45), a normal or high PaCO2 (40-45 mm Hg), and an elevated HCO3 (greater than 26 mEq/L). It occurs when there is an excess of bicarbonate in the body or a loss of acid.
The patient's ABGs align with metabolic alkalosis because of the high pH (7.6), normal PaCO2 (40 mm Hg), and elevated HCO3 (32 mEq/L).

Choice A rationale
Slowing of activity, also known as bradykinesia, is a common symptom of Parkinson’s disease. It is characterized by a general reduction in the speed and amplitude of voluntary movements, leading to difficulties with tasks such as walking, talking, and performing other self-care activities.
Choice B rationale
Muscle flaccidity is not typically associated with Parkinson’s disease. Instead, people with Parkinson’s often experience muscle rigidity or stiffness.
Choice C rationale
A gait with the body leaning backward is not a typical symptom of Parkinson’s disease. People with Parkinson’s disease often have a stooped posture, with the body leaning forward.
Choice D rationale
Continuous tremors are a hallmark symptom of Parkinson’s disease, but they are not present in all cases. Tremors in Parkinson’s disease are often described as a “pill-rolling” tremor because the movement resembles the motion of trying to roll a pill between the thumb and index finger.
