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 B

Explanation

A. MS is a chronic autoimmune disorder affecting the central nervous system (CNS), specifically the brain and spinal cord. It typically presents with a wide range of neurological symptoms such as blurred vision, sensory disturbances, weakness, and difficulties with coordination and balance. However, MS does not typically present with a sudden onset of ascending numbness and weakness starting in the feet and moving upwards.
B. GBS is an acute autoimmune disorder where the immune system attacks the peripheral nervous system. It often starts with numbness, tingling, and weakness in the feet and legs, which then

progresses symmetrically upwards to involve the upper limbs and potentially affect respiratory muscles. This ascending pattern of weakness is characteristic of GBS, making it the most likely diagnosis in this scenario.
C. Myasthenia gravis is a chronic autoimmune disorder affecting neuromuscular junctions, leading to muscle weakness and fatigue, especially with repetitive use. It typically presents with fluctuating muscle weakness that worsens with activity and improves with rest. The pattern of ascending numbness and weakness seen in the scenario does not align with the typical presentation of myasthenia gravis.
D. Parkinson's disease is a progressive neurological disorder primarily affecting movement. It presents with symptoms such as tremors, bradykinesia (slowness of movement), rigidity, and postural instability. It does not typically cause numbness or a symmetrical ascending pattern of weakness as described in the scenario.

A. The client follows a strict vegetarian diet. B. The client takes rosuvastatin for hyperlipidemia. C. The client takes propranolol for hypertension. D. The client uses acetaminophen for headaches

Correct Answer is C

Explanation

A. A vegetarian diet typically does not directly contribute to bronchoconstriction. In fact, a diet rich in fruits and vegetables may provide antioxidants and anti-inflammatory compounds that can be beneficial for respiratory health. Therefore, this option is less likely to be a cause of the client's bronchoconstriction.
B. Rosuvastatin (and other statins) are generally well-tolerated, but some individuals may experience respiratory side effects, including cough or shortness of breath. However, bronchoconstriction as a direct side effect of statins is uncommon and typically not a primary concern unless there is a rare hypersensitivity reaction.
C. Propranolol is a non-selective beta-blocker that can lead to bronchoconstriction, particularly in individuals with asthma or other respiratory conditions. Beta-blockers can block beta-2 receptors in the lungs, potentially causing constriction of the airways and worsening of respiratory symptoms.
D. Acetaminophen (paracetamol) is generally considered safe and does not typically cause bronchoconstriction. It is a non-steroidal anti-inflammatory drug (NSAID) that works differently from medications like beta-blockers, which directly affect the airways.
