A nurse teaches a nursing student about the differences between desmopressin (DDAVP) and vasopressin [Pitressin]. Which statement by the student indicates a need for further teaching?
a. "Desmopressin has a shorter duration of action than vasopressin."
b. "Desmopressin is easier to administer than vasopressin."
c. "Vasopressin can be used in cardiac re-suscitation."
d. "Vasopressin can cause serious adverse cardiovascular effects."
A
Desmopressin has a long duration of action, which is the reason it is preferred for the treatment of diabetes insipidus. It can be administered intranasally, so it is easier to administer than vaso-pressin. Vasopressin has hemodynamic effects that can be beneficial during cardiac resuscitation but that also can cause serious adverse cardiovascular effects.
