Answer to Question 1

B
Feedback:
Long nerves are myelinated: They have a myelin sheath that speeds electrical conduction and protects the nerves from the fatigue that results from frequent formation of action potentials, not from damage. Although myelin sheaths have Schwann cells, they do not produce these cells and the myelin sheath does not secrete neurotransmitters.

Answer to Question 2

D
Feedback:
Nursing diagnoses related to drug therapy might include: Risk for fluid volume imbalance related to cardiovascular effects. Deficient knowledge and acute pain might apply to this patient, but the priority nursing diagnosis this patient, but the priority nursing diagnosis for this patient is the risk for fluid imbalance related to cardiovascular effects. Monitoring for hypersensitivity is not a nursing diagnosis.
