Secondary suicide interventions consist of psycho-social, pharmacological, and resource care. Briefly describe and give examples of each. | Psychosocial- therapeutic relationship, reaffirm hope Resources- use the client's personal protective resources (history, social supports, PCP, effective coping skills) Pharmacological- SSRI's, ECT... |
A client would be deemed inappropriate for outpatient treatment for suicidal ideation if... -Intact support system -Unable to control impulses -Uses alcohol -Has history of seeking help -Suicide attempt -Lives alone -Low levels of stress | Unable to control impulses Suicide attempt Lives alone Mood altering substances (alcohol) |

If your frontal lobe is not functioning properly, you can expect... If the frontal lobe is working slowly you can expect... | Labile affect (extreme and quick mood changes) Slow- flat negative symptoms (depression) |
What do the basal ganglia do? | regulate and mediate motor activity, help express and regulate emotions and cognition Use dopamine to control motor activity (if block too much dopamine with schizophrenia treatment, can lead to motor movement complications like Parkinson's.) |
Where are the highest concentrations of dopamine found? | In the basal ganglia |
What is the Limbic system? What are it's part? | Responsible for emotional response of the brain. Consists of the Temporal lobe, Hippocampus and Amygdala (fear response) which help to experience, regulate, and integrate emotion memory and sensory data. Also consists of the Fornix or bridge. |

What puts you at risk for HTN during pregnancy? | First pregnancy or new partner Teens and over 35 Increased placental size (twins, diabetes) AA/Hispanic Family/Personal history OBESITY |
What are the 4 classifications of HTN? | Chronic HTN (begins prior to 20 weeks, doesn't resolve w/in 12 weeks post BP>140/90) Gestational HTN (BP>140/90 after 20 weeks, W/O proteinuria) Preeclampsia/eclampsia CHTN w/ preeclampsia |
What are the criteria for preeclampsia? | Begins after 20 weeks gestation, BP >140/90 twice, 4 hours apart AND Proteinuria (>300 mg/24hr urine colletion) OR Thrombocytopenia, Renal insufficiency, Impaired liver function, pulmonary edema, Cerebral/visual symptoms |
What is the classic preeclampsia triad? | BP >140/90 Proteinuria >300mg in 24 hr urine or >1+ in urine dipstick Edema |
When would someone be diagnosed with preeclampsia with severe features? | SBP >160 DBP>110 Thrombocytopenia Renal insufficiency Impaired liver function Pulmonary edema or Cerebral disturbance |
What is Eclampsia? | Meets criteria for preeclampsia (BP>140/90, Proteinuria(>300) or Edema, Thrombocytopenia, renal insufficiency, Impaired liver function, Cerebral/visual symptoms ++++ Grand mal seizure activity Leads to increased maternal mortality |
What is CHTN with superimposed preeclampsia? | Had HTN before 20 weeks gestation +++ New onset of Proteinuria Sudden increase in well controlled BP Any severe features of preeclampsia |
What is the cure for preeclampsia? | Delivery |
What is the pathophysiology of preeclampsia? | Vasospasm leads to decreased blood flow and tissue/cellular hypoxia Leads to endothelial damage (leaky vessels>edema and hypovolemia >decreased CO) Leads to platelet aggregation/clot formation (microvascular obstruction and further cellular hypoxia) |
You suspect a pregnant patient with hypertension has pulmonary edema. You want to know... | Is it cardiogenic (due to congestive heart failure) or is it non-cardiogenic (damaged vessels allow fluid to move into alveoli) |
How does preeclampsia affect the renal system? | Decreased urine output (<30mL/hour) > decreased GFR > decreased clearance of uric acid Severe vasospasm can damage endothelium leading to oliguria of pfogdinufiz |
A woman with preeclampsia complains of RUQ pain and nausea and vomiting. Your first action is... | Check for liver functioning, assume hepatic ischemia R/T preeclampsia May also indicate HELLP syndrome |
How does preeclampsia affect the placenta and thus the fetus? | High resistance and low blood flow leads to restricted gas exchange which can lead to intrauterine growth restriction Also Oligohydramnos, Pre-Term labor, Placental abruption, Infarction or intrauterine fetal demise |
What is HELLP syndrome? WHat are the SS? | Severe form of preeclampsia, diagnosed by lab values, hard to detect and increases maternal death. SS Tired, NV, RUQ pain, visual changes, Proteinuria, increased BP? Bruising under BP cuff? Hemolysis Elevated Liver enzymes Low platelets |
T/F- after delivery, the risk for eclampsia disappears? | False, there is a risk for eclampsia at anytime during and postpartum |
What does Magnesium Sulfate have to do with Preeclampsia? What are indicators of Mag Sulfate toxicity? How do you treat? | When a mom with preeclampsia is gong to deliver, give high loading doses (4-6 gm) and maintenance doses (1-3gm) to prevent seizures through 24 hours postpartum Toxicity: RR<12, Urine output <30mL/hr, Lethargy, change in LOC Treat with Calcium gluconate |
What are the common medications for preeclamptic mothers in acute hypertensive crisis? | Hydralazine, Labetolol, Nifedipine |
Describe the delivery timing and management for a mother with Preeclampsia WITHOUT severe features. | <37 weeks- bedrest, assessments 37-40 weeks- close assessments, risks vs. benefits, MgSO4 and delivery 40+ weeks- MgSO4 and delivery |
Describe the delivery timing and management for a mother with Preeclampsia WITH severe features. | <23 weeks- consider termination 24-32 weeks- steroids, close assessment, delivery? 32-34 weeks- MgSO4, antihypertensives, steroids, deliver in 24-48 hours, counsel risks/benefitys >34 weeks- MgSO4, antihypertensives, delivery |
Which DTR is most indicative for preeclampsia which may lead to eclampsia? | Hyperreflexia of the patella |
When do you need to notify the physician about a patient with preeclampsia? -SBP>160, DBP >110 -UOP<30 mL/hr -Worsening Headache, RUQ pain, visual changes, edema, changed LOC -Quick clotting -Improving lab values -RR<12, loss of DTR's | All except fast clotting (notify if prolonged bleeding) and improving labs (notify if worsening) |
White lists two classifications of diabetes in pregnancy, A1 and A2. Describe each. | A1- blood glucose levels are diet controlled A2- Blood glucose levels require medication |
T/F_ Insulin and glucose cross the placenta to maintain blood sugar in the fetus. | False- glucose crosses, insulin does NOT |
In which trimester(s) does insulin requirements increase? Decrease? | Decrease during first trimester (mom isn't eating as much, baby is taking more of the glucose, hormones are working) Increase during second and 3rd trimester |
Congenital malformations are a major concern in babies born to mothers with pregestational diabetes. What are the major ones? | Intrauterine fetal demise CNS malformations Big babies or growth restricted baby if poor placental blood flow |
How common is Gestational DM? What are the risks to the fetus? | Complicates 3-9% of all pregnancies Obese women who develop GDM are at increased risk to birth infant with CNS defect |
Who gets screened for Gestational DM? When? | Risk assessment performed at first visit for ALL women Screen ALL women at 24-28 weeks (may need earlier screening if history of diabetes or history of poor OB outcomes) |
How do you screen for Gestational DM? | 1-hour 50gram oral glucose tolerance test ->normal care +(>130)> 3 hour 100 gram test ->normal care + if 2+ values met positive for GDM Fasting-95 1hr-180 2hr-155 3hr-140 |
T/F- Hypoglycemia is a concern for baby of GDM mom. | True- baby may have low blood sugar after born because excess blood glucose is removed. Usually not major problem b/c baby is fed within 6 hours |
Part of the fetal surveillance in the 3rd trimester involves fetal kick counts. How many should you expect? | 10 fetal movements ever 2 hours |
How are insulin requirements affected in the 24 hours postpartum? | Insulin requirements decrease dramatically Risk for infection and hemorrhage increases due to uterine distention due to baby size/extra amniotic fluid |
How likely is it for a woman who had GDM to develop Type 2 diabetes? | 50% |
What are the target Blood Glucose levels during pregnancy? | Fasting- 60-99 1 hour post meal- 100-129 2 hours postmeal- <120 |
