The nurse knows which of the following phenomena listed below is an accurate statement about axonal transport?
A)
Anterograde and retrograde axonal transport allow for the communication of nerve impulses between the neuron and the central nervous system (CNS).
B)
Materials can be transported to the nerve terminal by either a fast or slow component.
C)
The unidirectional nature of the axonal transport system protects the CNS against potential pathogens.
D)
Axonal transport facilitates the movement of electrical impulses but precludes the transport of molecular materials.
Ans:
B
Feedback:
The bidirectional axonal transport system allows for the transport of molecular materials (as opposed to electrical impulses); anterograde transport has both slow and fast components.

A patient with hyperparathyroidism secondary to renal failure is prescribed calcimimetic. What should the nurse instruct the patient about this medication?
1. It increases the sensitivity of the calcium-sensing receptors of the parathyroid gland to serum calcium. 2. It blocks calcium receptors in the nervous and musculoskeletal systems. 3. It decreases resorption of calcium in the distal renal tubule. 4. It binds calcium to bile salts that are then excreted through the GI tract.
