How many milligrams of carbidopa is this patient taking per dose/tablet?

A) Peaked T waves:
Peaked T waves are a classic sign of hyperkalemia on an EKG. As potassium levels rise, the T waves become taller, more pointed, and narrow, indicating changes in the heart's electrical conduction. This is one of the earliest and most characteristic EKG changes seen with hyperkalemia. Hyperkalemia can result from conditions such as kidney dysfunction, use of potassium-sparing diuretics, or other electrolyte imbalances.

B) Inverted P waves:
Inverted P waves typically suggest issues such as atrial ischemia or ectopic atrial rhythms but are not a hallmark sign of hyperkalemia. They may also appear with other conditions, like atrial fibrillation or atrial flutter. However, inverted P waves are not typically linked to elevated potassium levels.

C) Widened QRS:
A widened QRS complex can occur in several conditions, including hyperkalemia, but it is generally seen in more severe cases. As potassium levels rise further, the QRS complex may widen due to delayed conduction through the ventricles. Although a widened QRS can indicate hyperkalemia, it is a later sign, and it typically occurs after more specific changes like peaked T waves.

D) Prominent U wave:
Prominent U waves are more often associated with hypokalemia (low potassium levels) rather than hyperkalemia. U waves are typically seen after the T wave on the EKG and can be more prominent in conditions of low potassium.

A. 250 mg:

This represents the amount of levodopa in the tablet, not carbidopa. Sinemet contains two active ingredients: carbidopa (25 mg) and levodopa (250 mg), as shown on the label.

B. 25 mg:

This is the correct answer, as the label indicates that each tablet contains 25 mg of carbidopa. Carbidopa is combined with levodopa to improve its effectiveness and reduce side effects like nausea.

C. 5 mg:

This is not accurate; the label clearly states that the carbidopa dose is 25 mg per tablet.

D. 200 mg:

This does not correspond to the dose of carbidopa or levodopa in this medication. The label specifies 25 mg of carbidopa and 250 mg of levodopa.
