Answer 25

- ensure safety - diffuse the situation - determine the problem - decrease the anxiety level - retun the pt to pre crisis level of functioning

Question 26

safety for suicide risk: nursing interventions fr pts at risk of suicide

Answer 26

- frequent monitoring: check on the suiicdal pt frequently but avoid a predictable routine and ensure that the pt is checked during extra busy imes like shift change. if the pt is actively suicidal, a psychiatric consultation will be required and the pt may be placed on a 1-1 precation until the pt can be moved to an appropriate treatment setting. 1:1 precautions: a statff member will be required to accompany the pt too and remain w the pt in the bathroom - safety: keep any potentially harmful items away from the pt such as knives, scissors, glass, razor blades, belts, nail files, electrical cords and even linens. informed visiors of anyr estrictions so that they do not bring items with pt may request. ensure the windows cannot be opened. the room may need to be searched periodically and the pt may need a body search and close monitoring int he bathroom. pts who are very high risk for suicide will need to wear paper gons and to have paper bedding. plastic trash bags with the pt could use to suffocate themselves should not be used on the pts room - communication: ask outright if the pt is considering suicide and if so how and when. a pt is at higher risk if they have a specific plan with a highly lethal method that is available to them. asking a pt to talk about suicidal thoughts does not increase the chance of their completing a suicide. rather it demonstrates caring and acknowledges their value as a person. when talking to someone who is suicidal, avoid platitutdes like "think what this would do to your children." often the suicidal person is so immersed in feelings of hopelessness and isolation that they are unable to identify ith how others are feeling. when working on problem solving, break down one problem into manageable steps rather than looking at the whole picture, which can be overhelming. most people ewho are suicidal have ambivalent or mixed feelings about taking action. Supporting the reasons the preson does not want to end their life can help the person to reevaluate the situation

Question 41

neuroleptic malignant syndrome

Answer 41

- rare but potentially fatal reaction to treatment with some antipsychotic medications - symptoms include muscle rigidity, hyperpyrexia, fluctuations in bp, and altered LOC - early recognition and immediate medical care are important. signs of ANS instability that frequently accompany NMS include labile bp, taypnea, tachycardia, sialorrhea, diaphoresis, flushing, skin pallor, and incontinence. when symptoms appear, progression can be rapid and can reach peak intensity in as little as 3 days. FEVER = fever, encephalopathy, vital signs unstable, elevated enzymes (CPK), rigidity of muscles - some antipsychotics such as clozapine are known to cause serious blood dyscrasias and require regular monitoring of blood counts 0 the high potency first generation antipsychotics such as fluphenazine, trifluoperazine, haloperidol, loxapine, pimozide, perphenazine, and thyroxine are most likely to cause NMS

Question 42

who is most likely to be at risk of development neuroleptic malignant syndrome

Answer 42

- any individual starting an antipsychotic has the potential risk for developing NMS. almost all dopamine antagonists can cause NMS and higher potency antipsychotics pose a greater risk compared with low potency agents and atypical antipsychotics

Question 43

nursing process: goals/evaluation

Answer 43

- accuracy of verbal and written reporting of the pts progress will help determine whether the interventions have been helpful or that they need to be reevaluated and changed - in some instances, some of the interventions can be terminated depending on the pts progress

Question 44

nursing outcomes classification (NOC)

Answer 44

- standardized language that provides outcome statements, a set of indicators describing specific pt, caregiver, family, or community states related to the outcome, and to five point measurement scale to facilitate racking pts across the care settings - NOC can help demonstrte pt progress even when outcomes are not fully met - it is applicable in all care settings and specialties

Question 45

some questions to reflect for the teaching plan

Answer 45

- how do you know the pt has grasped the teaching - what do you look for - do you need to ask for feedback or return demonstration - does the feedback or return demonstration need to be perfect - how did you do as a teacher - did you achieve the plan - did you have enough time - what will you do differently next time - does the pt show evidence that their behavior may change as a result of the teaching plan - evaluation criteria may change from time to time as well

Question 46

MAOIs: contrandications

Answer 46

- should be given carefully to pts who have asthma, CHF, cerebral vascular disease, glaucoma, hypertension, schizophrenia, alcoholism, liver or kidney disorders, or severe headaches, as well as those who are over 60 years old who are pregnant

Question 47

cognitive group therapy

Answer 47

- the goal is to decrease the pts emotional discomfort, increase the pts social functioning, increase the pts ability to behave or to perform in a manner appropriate for the situation - group therapy: can include formal psychotherapy groups where patients meet w/ a therapist regularly as part of their treatment; self help programs are also a form of group therapy; as a rule AA meetings are "closed"; therapists and counselors are facilitators. they do not heal the pts the patient heals themselves. ideally pts take the suggestions give try them and see if it works. nurses can reinforce the good work pts do in learning to keep themselves healthy. nurses can also emind pts gently that they are doing their own healing - an offshoot of REBT is known as CBT. CBT is behavioral therapy that focuses on examining the relationships between thoughts, feelings, and behaviors. CBT is differnt from traditional psychodynamic psychotherapy and that the therapist and the pt actively worked together to help the pt recover from mental illness.

Question 48

ECT

Answer 48

- ect has an extensive history. not as traumatizing to the pt as it was in the 50s and can be done as an outpatient procedure - alternatve where nothing else works. can be used for depression or schizoprenia where medication hasn't been effective. - nurses carefully monitor bp and pulse before and after treatment as ect delivers a small electrical charge to the brain for about 30 seconds, causing a "seizure". pt is sedated/unconscious. - desired outcome; pt will state and exhibit appropriate mood and affect or measurable improvement in mood and affect - nursing considerations: monitor vitals before and after treatmnt, maintain safety after the treatment, premedicate if ordered - pt teaching: may be disoriented after treatment, may lose short term memory, side effects may last up to 24 hours
