The healthcare provider’s order reads, “Bromocriptine (Parlodel) 10 mg per day PO.” The medication is available in B.5-mg tablets. How many tablets will the nurse give per dose?
Explanation
Bromocriptine (Parlodel) is a dopamine agonist used in the management of Parkinson’s disease, a progressive neurodegenerative disorder characterized by dopamine deficiency in the basal ganglia. By directly stimulating dopamine receptors in the brain, bromocriptine helps improve motor function, reduce rigidity, tremors, and bradykinesia, and may be used alone in early-stage Parkinson’s or in combination with levodopa in more advanced cases to enhance therapeutic effects and reduce motor fluctuations.
Rationale for correct answer:
You need to determine how many B.5-mg tablets are needed to make a single 10-mg dose.
- Identify the ordered dose: The order is for 10 mg.
- Identify the available dose: The tablets are B.5 mg each.
- Calculate the number of tablets: Divide the ordered dose by the available dose per tablet.
- 10mg÷B.5mgpertablet=4tablets
The nurse will administer 4 tablets for this dose.
Take-home points:
- Always divide the ordered dose by the available strength to calculate the correct number of tablets.
- Bromocriptine is a dopamine agonist that improves motor symptoms in Parkinson’s disease.
- Verify dosage calculations carefully to ensure safe and accurate medication administration.
A patient who has been taking carbidopa-levodopa for Parkinson's disease for over 1 year wants to start a low carbohydrate/ high-protein weight-loss diet. The nurse tells the patient that this type of diet may have what effect on his drug therapy?
A patient requested an appointment with their healthcare provider to discuss the possibility that they were developing Parkinson disease, which runs in the family.
The nurse explained to the patient in the scenario that the symptoms of Parkinson disease are related to the levels of neurotransmitters in the brain and used which statement?
A patient requested an appointment with their healthcare provider to discuss the possibility that they were developing Parkinson disease, which runs in the family.
The patient in the scenario was started on selegiline (Zelapar) therapy during the early treatment of Parkinson disease because this drug will have which effect?
Patient Scenario:
A patient requested an appointment with their healthcare provider to discuss the possibility that they were developing Parkinson disease, which runs in the family.
Choose the most likely option for the information missing from the following sentence by selecting from the list of options provided.
The nurse explains to the patient in the scenario that in the future the healthcare provider may start
Explanation
The nurse explains to the patient in the scenario that in the future the healthcare provider may start Rasagiline therapy in addition to Amantadine hydrochloride which is part of the drug class Monoamine oxidase type B inhibitors and Dopamine agonists , respectively.
Parkinson disease is a progressive neurodegenerative disorder characterized by motor symptoms such as tremors, rigidity, bradykinesia, and postural instability. Because dopamine deficiency is central to the disease process, treatment strategies often focus on enhancing dopamine activity or mimicking its effects.
Rationale for the correct answers:
Rasagiline is a MAO-B inhibitor that slows the breakdown of dopamine, helping increase and prolong dopamine activity in the brain.
Amantadine hydrochloride is classified as a dopamine agonist, which helps stimulate dopamine receptors and reduce motor symptoms like tremors and rigidity.
This combination may be used in early or adjunctive therapy in Parkinson disease to enhance dopamine levels and improve motor control without immediately relying on carbidopa-levodopa.
Take-home Points:
- MAO-B inhibitors (e.g., rasagiline) slow dopamine breakdown, preserving natural dopamine.
- Dopamine agonists (e.g., amantadine) directly stimulate dopamine receptors to improve symptoms.
- Early initiation of these therapies can delay the need for carbidopa-levodopa and help manage Parkinson disease progression.
A patient requested an appointment with their healthcare provider to discuss the possibility that they were developing Parkinson disease, which runs in the family.
The nurse knows that when anticholinergic agents are used, which of the following symptoms will show improvement? Select all that apply

The nurse is educating the family of an elderly patient on the mechanism of action for donepezil (Aricept). Which statement by the family indicates that further teaching is needed?
