A client with Parkinson's disease is started on Levodopa with Carbidopa (Sinemet). What should the nurse include in the patient teaching?

"Carbidopa crosses the blood-brain barrier where it is then converted to dopamine."

"It may take weeks to begin seeing the effects of this medication."

“You will remain on the same dosage of this medication for the rest of your life."

"Levodopa protects carbidopa, preventing carbidopa from being broken down before it reaches the brain."

Answer and Explanation

The Correct Answer is B

A.   Carbidopa itself does not cross the blood-brain barrier. Its primary role in Sinemet is to inhibit the peripheral breakdown of levodopa (the precursor of dopamine) into dopamine before it reaches the brain.
B.   It is true that it may take a few weeks to see the full effects of this medication, as the body needs time to adjust to it.
C.   Parkinson's disease is progressive, and as the disease advances, the dosage and frequency of levodopa with carbidopa may need to be adjusted to maintain symptom control. Over time, higher doses or additional medications may be required to manage symptoms effectively.
D.   Levodopa does not protect Carbidopa; rather, Carbidopa protects Levodopa from early conversion to dopamine outside the brain, which would make it less effective.

Correct Answer is C

Explanation

A. While assessing pedal pulses is important for circulation and can indicate peripheral vascular status, it is not the highest priority compared to assessing renal function in a client with TTP.
B. Nutritional status is important for overall health and recovery but is not immediately critical compared to assessing for acute complications such as kidney damage in TTP.
C. TTP can lead to kidney damage due to the formation of clots in the small blood vessels of the kidneys. This can result in decreased urine output or even acute kidney injury (AKI). Monitoring urine output is crucial to assess renal function and detect early signs of kidney involvement.
D. TTP primarily affects the kidneys and blood coagulation system, leading to hemolysis and thrombocytopenia. Liver function is not typically a primary concern in TTP unless there are concurrent issues or complications.

desired dose / available dose) x available volume.

The desired dose is 250 mg, and the available dose is 1000 mg in 8 mL.

So, the calculation is (250 mg / 1000 mg) x 8 mL, which equals 2 mL. Therefore, the nurse should administer 2 mL of hydrocortisone sodium succinate.
