What is going on?Goals of Lecture:
How do I make my X-cover list?How do I identify emergency from non-
emergency?How do I know when I need to go and see the
patient?How do I handle common calls/questions?When do I need to call my resident???
![Page 3: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/3.jpg)
How to make your CareGate list:Log on to CareGateGo to Cross CoverUnder “problems”, put one liner about the
patientThen list all important problems and what has
been done about themUnder “to do” section put MR number, pt
allergies, important meds, anything for X-cover to follow up on
![Page 4: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/4.jpg)
Example:69 y/o with PCKD and transplant kidney p/w painless
hematuria1. Renal: pt continues to have hematuria: likely ruptured renal
cysts 2/2 PCKD, considering CT abd and MRI results. Also worrying about infx, CA, etc. Continue immunosuppression with Cellcept, prednisone. CMV/EBV by PCR neg. Urology following - possible cystoscopy to r/o bladder source.
2.Htn: BP well controlled.3.Paroxysmal AF: atenolol and Cardizem. Short episode of afib
with RVR overnight, with rates of 120s. Continue ASA for prophylaxis.
4.Hypothyroidism - continue replacement.5.Anxiety - continue Ativan.6.RA-pain relief.7.Insomnia: Ambien.8.Wt loss: cancer w/u.9.Choledocholithiasis and pancreatic duct stones: ERCP
today.

Example, continued:Cross Cover To Do
F/u ERCP resultsALL: NKDARX: allopurinol, aspirin, atenolol, Lipitor … You get the idea!
![Page 6: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/6.jpg)
Not Acceptable:“Patient intubated, sedated, in 1 ICU”… when the pt
has been extubated and on the floor for 4 daysMust update room numbers on x-cover listMust update DNR statusMust put pertinent changes in status (e.g., if a
patient went into afib or had GI bleed or is having a procedure)
Must put all pending tests on the listIf someone is really sick, include family contact info
in the event of a code or critical change in medical status
YOU MUST UPDATE THE WHOLE LIST EVERYDAY!!!
![Page 7: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/7.jpg)
What do I do when I’m called?We will go through some basics by organ
systems today
Future subjects to be covered during Internship 101 lecture series:ID: June 30: Pneumonia CV: July 3: Arrhythmias GI: July 7: GI bleeding Pulm: July 10: Sepsis/SIRS Endo: July 17: Hyperglycemic states (DKA and
HONC) Neuro: July 31: Altered mental status and “Brain
Code”

Altered Mental StatusAlways go to the bedside!!!Try to redirect patient: drowsy, stuporous, making
inappropriate comments?Is this a new change? How long?Check for any recent/new medications
administeredCheck VITALS, alertness/orientation, pupils,
nuchal rigidity, heart/lungs/abdomen, strengthScan recent labs in chart including: cardiac
enzymes, electrolytes, +culturesIf labs unavailable, get stat Accucheck, oxygen
saturationTry naloxone (Narcan), usually 0.4-1.2 mg IV, if
there is any possibility of opiate OD
![Page 10: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/10.jpg)
“Move Stupid” Metabolic – B12 or thiamine deficiency Oxygen – hypoxemia is a common cause of confusion
Others - including anemia, decreased cerebral blood flow (e.g., low cardiac output),
CO poisoning Vascular – CVA, intracerebral hemorrhage, vasculitis, TTP, DIC,
hyperviscosity,hypertensive encephalopathy
Endocrine – hyper/hypoglycemia, hyper/hypothyroidism, high /low cortisol states and Electrolytes – particularly sodium or calcium
Seizures –post–ictal confusion, unresponsive in status epilepticus; also consider Structural problems – lesions with mass effect, hydrocephalus
Tumor, Trauma, or Temperature (either fever or hypothermia) Uremia – and another disorder, hepatic encephalopathy Psychiatric – diagnosis of exclusion; ICU psychosis and "sundowning" are
common Infection – any sort, including CNS, systemic, or simple UTI in an elderly
patient Drugs – including intoxication or withdrawal from alcohol, illicit or
prescribed drugs
![Page 11: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/11.jpg)
SeizuresGo to bedside to determine if patient still actively seizingCall your residentCheck your ABCsPlace patient in left lateral decubitus positionImmediate AccucheckIf still seizing, give diazepam 2mg/min IV until seizure
stops or max of 20mg (alternative: lorazepam 2-4mg IV over 2-5min)
Give thiamine 100 mg IV first, then 1 amp D50Load phenytoin 15-20 mg/kg in 3 divided doses at 50
mg/min (usually 1 g total) Remember, phenytoin is not compatible with glucose-
containing solutions or with diazepam; if you have given these meds earlier, you need a second IV!
If still seizing >30min, pt is in status—call Neuro (they can order bedside EEG)
Get Head CT if appropriate and if pt stabilized
![Page 12: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/12.jpg)
Cord CompressionSuspect in patients with new weakness or change in
sensation (especially if they have a demonstrable level), new bowel/bladder retention or incontinence.
Prognosis is dismal for pts w/no function for >24h.Prognosis is best for pts with new, incomplete loss (i.e.
weakness). Surgical emergency: call Neurosurgery.Stabilize the spine: collars for C-spine, Turtle shells
(TLSO) for T/L-spine.Dexamethasone not always indicated (in case of
traumatic fracture, for instance).If tumor, needs immediate radiotherapy.
![Page 13: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/13.jpg)
FallsGo to the bedside!!!Check mental statusCheck vital signs including pulse oxCheck med listCheck blood glucoseExamine pt to ensure no fracturesThorough neuro checkCheck tilt blood pressures if appropriateIf on coumadin/elevated INR—consider head CT
to r/o bleed
![Page 14: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/14.jpg)
Delirium Tremens (DTs)Give thiamine 100mg, folate 1mg, MVISee if patient has alcohol historyCheck blood alcohol levelDTs usually occur ~ 3 days after last ingestionMake sure airway is protected (vomiting risk)Use Ativan 2mg at a time until pt calm, may
need Ativan drip, make sure you do not cause respiratory depression
Monitor in ICU for seizure activityAlways keep electrolytes replaced
![Page 15: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/15.jpg)
PULMONARYShortness of BreathOxygen De-saturations
![Page 16: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/16.jpg)
Shortness of BreathGo to the bedside!!!Check an oxygen saturation and ABG if indicatedCheck CXR if indicated
![Page 17: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/17.jpg)
Causes of SOBPulmonary:
Pneumonia, pneumothorax, PE, aspiration, bronchospasm, upper airway obstruction, ARDS
Cardiac: MI/ischemia, CHF, arrhythmia, tamponade
Metabolic: Acidosis, sepsis
Hematologic: Anemia, methemoglobinemia
Psychiatric: Anxiety – common, but a diagnosis of exclusion!
![Page 18: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/18.jpg)
Oxygen DesaturationsSupplemental OxygenNasal cannula: for mild desatsFace mask/Ventimask: offers up to 55% FIO2Non-rebreather: offers up to 100% FIO2BIPAP: good for COPD
Start settings at: IPAP 10 and EPAP 5IPAP helps overcome work of breathing and helps to
change PCO2EPAP helps change pO2
CPAP: good for pulmonary edema, hypercapnea, OSAStart at 5-7
![Page 19: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/19.jpg)
Indications for IntubationUncorrectable hypoxemia (pO2 < 70 on
100% O2 NRB)Hypercapnea (pCO2 > 55) with acidosis
(remember that people with COPD often live with pCO2 50–70 +)
Ineffective respiration (max inspiratory force < 25 cm H2O)
Fatigue (RR>35 with increasing pCO2)Airway protectionUpper airway obstruction
![Page 20: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/20.jpg)
Mechanical VentilationIf patient needs to be intubated, start with
mask-ventilation until help from upper level Arrives
Initial settings for Vent:A/C FIO2 100 Vt 700 Peep 5 (unless
increased ICP, then no peep) RR 12Check CXR to ensure proper ETT placement
(should be around 4cm above the carina)Check ABG 30 min after pt intubated and
adjust settings accordingly
![Page 21: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/21.jpg)
CARDIOLOGYChest painHypotensionHypertensionArrhythmias
![Page 22: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/22.jpg)
Chest PainGo and see the patient!!!Why is the patient in house?Recent procedure?STAT EKG and compare to old onesIs the pain cardiac/pulmonary/GI?—from H+PVital signs: BP, pulse, SpO2If you think it’s cardiac:
Give SL nitroglycerin if pain still present (except if low blood pressure, give morphine instead)
Supplemental oxygenAspirin 325 mg
![Page 23: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/23.jpg)
HypotensionGo and see the patient!!!Repeat Manual BP and HRLook at recent vitals trendsLook for recent ECHO/ meds pt has been given.EXAM:
Vitals: orthostatic? tachycardic? Neuro: AMS HEENT: dry mucosa? Neck: flat vs. JVD (=CHF) Chest: dyspnea, wheezes (?anaphylaxis), crackles (=CHF) Heart: manual pulse, S3 (CHF) Ext: cool, clammy, edema
![Page 24: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/24.jpg)
Management of HypotensionIf offending med, stop the med!If volume down/bleeding: give wide open IV NSCorrect hypoxiaRecent steroid use? Adrenal insufficiencyIs there a neuro cause for hypotension?If appropriate, consider: PE, tamponade,
pneumothoraxIf fever, consider sepsis—need for empiric antibioticsIf hives and wheezing, consider anaphylaxis—tx with
oxygen, epinephrine, BenadrylNeed for pressors? Transfer to ICU!
![Page 25: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/25.jpg)
Commonly Used PressorsName Receptor
AffectedDose Action
Phenylephrine(Neosynephrine)
Alpha 1 10–200 mcg/min
Pure vasoconstrictor; causes ischemia in extremities
Norepinephrine(Levophed)
A1, B1 2–64 mcg/min Vasoconstriction, positive inotropy; causes arrhythmias
Dopamine Dopa 1–2 mcg/kg/min
Splanchnic vasodilation ("renal dose dopamine" even though many doubt such effect exists)
B1 2–10 mcg/kg/min
Positive inotropy; Causes Arrhythmias
A1 10–20 mcg/kg/min
Vasoconstriction; Causes Arrhythmias
Dobutamine B1, B2 1–20 mcg/kg/min
Positive inotropy andchronotropy; Causes Hypotension

HypertensionIs there history of HTN?
Check BP trendsIs patient having pain, anxiety, headache, SOB?Confirm patient is not post-stroke pt—BP parameters
are different: initial goal is BP>180/100 to maintain adequate cerebral perfusion
EXAM: Manual BP in both arms Fundoscopic exam: look for papilledema and hemorrhages Neuro: AMS, focal weakness or paresis Neck: JVD, stiffness Lungs: crackles Cardiac: S3
![Page 27: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/27.jpg)
Management of HypertensionIf patient is asymptomatic and exam is WNL:
See if any doses of BP meds were missed; if so, give now
If no doses missed, may give an early dose of current med
Remember, no need to acutely reduce BP unless emergency
So, start a medication that you would have normally picked in this patient as the next agent of choice according to JNC/co-morbidities/allergies
![Page 28: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/28.jpg)

Nausea/VomitingVital signs, blood sugar, recent meds?Make sure airway is protectedEXAM: abdominal exam, rectal (considering
obstruction, pancreatitis, cholecystitis),neuro exam (increased ICP?)
May check KUB Treatment:
Phenergan 12.5-25mg IV/PR (lower in elderly)Zofran 4-8mg IVReglan 10-20 mg IV (especially if suspect gastroparesis)If no relief, consider NG tube (especially if suspect
bowel obstruction)

ConstipationVery common call!Check: electrolytes, pain meds, bowel regimenCheck KUB if suspect ileus/obstructionRectal exam to check for fecal
impaction/mechanical obstructionTreatment:
If not acute process, can order “laxative of choice”Fleets enema for immediate relief (unless renal
failure b/c high phos—then can order water/soap suds enema)
Lactulose/mag citrate PO if no mechanical obstruction
![Page 33: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/33.jpg)
DiarrheaCheck: electrolytes, vitals, medsQuantify volume, number, description of stoolsLabs: fecal leukocytes, stool culture, guaiac,
C.diff toxin if recent antibiotic or nursing home resident
Treatment: Colitis: flagyl 500mg po tidGI bleed: per GI sectionIf don’t suspect infection: loperamide initially 4mg
then 2mg after each unformed stool up to 16mg daily
![Page 34: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/34.jpg)
Acute Abdominal PainGo to the bedside!!!Assess vitals, rapidity of onset, location, quality and
severity of painLOCATION:Epigastric: gastritis, PUD, pancreatitis, AAA, ischemiaRUQ: gallbladder, hepatitis, hepatic tumor, pneumoniaLUQ: spleen, pneumoniaPeri-umbilical: gastroenteritis, ischemia, infarction,

Acute Abdomen?Assess severity of pain, rapidity of onsetIf acute abdomen suspected, call SurgeryDo you need to do a DRE?KUB vs. Abdominal Ultrasound vs. CTTreatment:
Pain management—may use morphine if no contraindication
Remember, if any narcotics are started, use sparingly in elderly, ensure pt on adequate bowel regimen
![Page 36: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/36.jpg)

Decreased Urine OutputOliguria: <20 cc/hour (<400 cc/day)Check for volume status, renal failure, accurate
I/O, medsConsider bladder scanLabs:
UA: WBC (UTI); elevated specific gravity (dehydration); RBC (UTI/urolithiasis); tubular epithelial cells (ATN); WBC casts (interstitial nephritis); Eosinophils (interstitial casts)
Chemistries: BUN/Cr, K, Na
![Page 38: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/38.jpg)
Treatment of Decreased UOPDecreased Volume
Status:Bolus 500 cc NSRepeat if no effect
Normal/Increased Volume:
May ask nursing to check bladder scan for residual urine
Check Foley placement
Lasix 20 mg IV
![Page 39: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/39.jpg)
Foley Catheter Problems:Why/when was it placed?Does the patient still need it?Confirm no kinks or clampsConfirm bag is not fullExamine output for blood clots or sedimentDo not force Foley in if giving resistanc: call
UrologyNursing may flush out Foley if it must stay inThe sooner it’s out, the better (when
appropriate)
![Page 40: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/40.jpg)
HyperkalemiaEnsure correct value—not hemolysis in labCheck for renal insufficiency, medsCheck EKG for acute changes, peaked T-
waves, PR prolongation followed by loss of P waves, QRS widening
![Page 41: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/41.jpg)
Treatment of HyperkalemiaImmediate Rx (works in minutes): for EKG changes,
stabilize myocardium with 1-2 amps calcium gluconate Temporary Rx (shift K into cells):
2 amps D50 plus 10 units regular insulin IV: decreases K by 0.5-1.5 mEq/L and lasts several hours
2 amps NaHCO3: best reserved for non-ESRD patients with severe hyperkalemia and acidosis
B2-agonists: effects similar to insulin/D50Long-lasting Elimination:
Kayexalate 30g po (repeat if no BM) or retention enemaNS and LasixDialysis

DKAIdentify precipitating factor (e.g., infection, MI,
noncompliance with meds)Check for anion gapCheck for ketones in urine or serumGive bolus 1 Liter NS, then run IVF at 200
ml/hour if no contraindicationStart insulin drip DKA protocol in ICU (EPIC
order)Check electrolytes every 4 hours and replace as
appropriate
![Page 44: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/44.jpg)
HONCSimilar to DKA but for Type II diabetes and no
ketonesThere is also an insulin drip NON-DKA protocol
in ICU (EPIC order)

Positive Blood CultureYou get called by the lab because a blood culture
has become Positive.Check if primary team had been waiting on blood
culture.Is the patient very sick/ ICU?Is the culture “1 out of 2” and/or “coag negative
staph”? This is likely a contaminant.If pt is on abx, make sure appropriate coverage
based on culture and sensitivityIf you believe it to be true Positive then give
appropriate empiric treatment for organism and likely source of infection/co-morbidities of patient and discuss with primary team in the AM

FeverHas the patient been having fevers?DDX: infection, inflammation/stress rxn, ETOH
withdrawal, drug rxn, transfusion rxnIf the last time cultures were checked >24 hrs
ago, then order blood cultures x 2, UA/culture, CXR, respiratory culture if appropriate
If cultures are all negative to date, likely no need to empirically start abx unless a source is apparent and you are treating a specific etiology

AnticoagulationAppropriate for DVT, PE, Acute Coronary SyndromeUsually start with low molecular weight heparin—
(Lovenox) 1 mg/kg every 12 hours and adjust for renal fxnIf need to turn on/off quickly (e.g., pt going for procedure)
use heparin drip—there is a protocol in EPICRisk factors for bleeding on heparin:
Surgery, trauma, or stroke within the previous 14 daysHistory of peptic ulcer disease, GI bleeding or GU bleedingPlatelet count less than 150KAge > 70 yrsHepatic failure, uremia, bleeding diathesis, brain mets

Blood Replacement ProductsPRBC: One unit should raise Hct 3 points or Hgb
1 g/dlPlatelets: One unit should raise platelet count by
10K; there are usually 6 units per bag ("six-pack")use when platelets <10-20K in nonbleeding
patient.use when platelets <50K in bleeding pt, pre-op pt,
or before a procedureFFP: contains all factors
use when patient in DIC or liver failure with elevated coags and concomitant bleeding or for needed reversal of INR

RADIOLOGYWhat test do I order for what problem?
Plain FilmsCT scansMRI

Plain FilmsCXR:Portable if pt in unit or bed boundPA/Lat is best for looking for effusions/infiltratesDecubitus to see if an effusion layers; needs to
layer >1cm in order to be safe to tap
Abdominal X-ray:Acute abdominal series: includes PA CXR,
upright KUB and flat KUB
![Page 53: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/53.jpg)
CTHead CT
Non-contrast best for bleeding, CVA, traumaContrast best for anything that effects the blood
brain barrier, tumors, infectionCT Angiogram
If suspect PE and no contraindication to contrast (e.g., elevated creatinine)
Abdominal CT Always a good idea to call the radiologist if unsure whether
contrast is needed/depending on what you are looking for Renal stone protocol to look for nephrolithiasis If you have a pt who has had upper GI study with contrast,
radiology won’t do CT until contrast is gone—have to check KUB to see if contrast has passed first

MRIIncreased sensitivity for soft tissue pathologyBest choice for:
Brain: neoplasms, abscesses, cysts, plaques, atrophy, infarcts, white matter disease
Spine: myelopathy, disk herniation, spinal stenosis
Contraindications: pacemaker, defibrillator, aneurysm clips, neurostimulator, insulin/infusion pump, implanted drug infusion device, cochlear implant, any metallic foreign body

Pronouncing a PatientCheck for:Spontaneous movementIf on telemetry—any meaningful activityResponse to verbal stimuliResponse to tactile stimuli (nipple pinch or
sternal rub)Pupillary light reflex (should be dilated and fixed)Respirations over all lung fieldsHeart sounds over entire precordiumCarotid, femoral pulses
![Page 57: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/57.jpg)
Notify the Patient’s FamilyCall family if not present and ask to come in, or
if family is present:Explain to them what happened Ask if they have any questionsAsk if they would like someone from pastoral care
to be calledLet them know they may have time with the
deceasedNursing will put ribbon over the door to give
family privacy

Request an AutopsyAsk family if they would like an autopsy
Medical Examiner will be called if:Patient hospitalized <24 hoursDeath associated with unusual circumstancesDeath associated with trauma
![Page 59: Nadia Habal, MD Presbyterian Hospital of Dallas X-COVER?!?](https://reader035.fdocuments.net/reader035/viewer/2022062620/551b21a4550346d41a8b45ea/html5/thumbnails/59.jpg)
How to Write a Death NoteDOCUMENTATION:“Called to bedside by nurse to pronounce (name of
pt).”Chart all findings previously discussed:
“No spontaneous movements were present, pupils were dilated and fixed, no breath sounds were appreciated, etc.”
“Patient pronounced dead at (date and time).”“Family and attending physician were notified.”“Family accepts/declines autopsy.”Document if patient was DNR/DNI vs. Full Code.

Bottom Line:When in doubt, call your ResidentIt is OK to call your attending if over your headYou are Never All Alone
Write a NOTE about what has happened for the primary team
Call primary team in the AM about important events.
Have fun…it’s gonna be a great year!
