11. Monitor respiratory, thyroid, and neurological
                                                functions.
                                           12. Instruct the client to change positions slowly to
                                                minimize orthostatic hypotension.
                                           13. Instruct the client taking amiodarone to use sunscreen
                                                and protective clothing to prevent photosensitivity
                                                reactions.
                                           14. Encourage the client to increase fiber intake to prevent
                                                constipation.

                                             1. Increases myocardial force and cardiac output through
                                                stimulation of β-receptors
                                             2. Used in clients with heart failure and for clients
                                                undergoing cardiopulmonary bypass surgery

                                        B. Dopamine

                                             1. Increases BP and cardiac output through positive
                                                inotropic action and increases renal blood flow
                                                through its action on α- and β-receptors
                                             2. Used to treat mild kidney failure caused by low
                                                cardiac output
                                C. Epinephrine
                                             1. Used for cardiac stimulation in cardiac arrest
                                             2. Used for bronchodilation in asthma or allergic
                                                reactions
                                             3. Produces mydriasis
                                             4. Produces local vasoconstriction when combined with
                                                local anesthetics and prolongs anesthetic action by
                                                decreasing blood flow to the site
                                D. Norepinephrine
                                             1. Stimulates the heart in cardiac arrest
                                             2. Vasoconstricts and increases the BP in hypotension
                                                and shock

                                        E. Side and adverse effects

                                             4. Restlessness
                                             5. Urgency or urinary incontinence

                                        F. Interventions
