Question 1 of 5
The client, who has type I DM, is scheduled for an MRI of the brain after an MVA. Which intervention should the nurse implement to prepare the client for the test?
Correct Answer: B
Rationale: Clients undergoing positron emission tomography (PET) scans are made NPO and have insulin held, but not those undergoing MRI. Clients are given earplugs to wear while undergoing the test because the machine makes a loud clanging noise that is unpleasant. Clients undergoing cerebral angiography, not MRI, must be on bedrest with the extremity used for injection straight for several hours after the test. Serum BUN and creatinine levels to assess renal function are required before CT scans or other tests involving contrast material to prevent renal complications.
Question 2 of 5
The client diagnosed with PD is being discharged on carbidopa/levodopa (Sinemet), an antiparkinsonian drug. Which statement is the scientific rationale for combining these medications?
Correct Answer: C
Rationale: Carbidopa inhibits peripheral breakdown of levodopa, allowing more levodopa to cross the blood-brain barrier and convert to dopamine (
C). This enhances efficacy and reduces side effects. Other options are incorrect.
