Pharmacological and Parenteral Therapies 17.
A nurse can anticipate anticholinergic side efects are likely when
a patient is taking: A. lithium (Lithobid). B. isperidone (Risperdal). C.
buspirone (BuSpar). D. fluphenazine (Prolixin). ANS: D Fluphenazine,a first-
generation antipsychotic, exerts muscarinic blockade, resulting in dry
mouth, blurred vision, constipation, and urinary retention. Lithium therapyis
more often associated with fluid balance problems, including
polydipsia, polyuria, and edema. Risperidone therapyis more often
associated with movementdisorders, orthostatic hypotension, and
sedation. Buspirone is associated with anxiety reduction without
major side efects. KEY: Cognitive Level: Application | Integrated

instructs a patient taking a drug that inhibits monoamine oxidase
(MAO) to avoid certain foods and drugs because of the risk
of: A. hypotensive shock. B. hypertensive crisis. C. cardiac dysrhythmia. D.

cardiogenic shock ANS: B Patients taking MAO-inhibiting drugs must be
on a tyramine-free diet to preventhypertensive crisis. In the
presence of MAOIs, tyramine is not destroyed by the liver
and in high levels produces intense vasoconstriction, resulting
in elevated blood pressure. KEY: Cognitive Level: Comprehension|

19. A patient has taken many conventional antipsychotic drugs over years.
The health care provider, concerned about early signs of tardive
dyskinesia, prescribes risperidone (Risperdal). A nurse planning
care for this patient understands that

administering psychotropic medications should be prepared to
intervene when giving a drug that blocks the attachment of
norepinephrine to alpha-1 receptors because the patient may
experience: A. increased psychotic symptoms. B. a hypertensive crisis.
C. orthostatic hypotension. D. severe appetite disturbance. ANS: C Sympathetic
mediated vasoconstriction is essential for maintaining normal
blood pressure in the upright position. Blockage of alpha-1
receptors leads to vasodilation and orthostatic hypotension.
