HOW TO SURVIVE YOUR FIRST NIGHT ON CALL
![Page 2: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/2.jpg)
Objectives
Have a few tools for common on-call issues
Give appropriate checkout Prevent disasters
![Page 3: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/3.jpg)
Your first night on call
The pager goes off…
![Page 4: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/4.jpg)
Potential news on the other end of the phone
“You have (another) direct admission on F8.”
“Your patient in F 605 is crashing.” “The lady in H 613 would like something
to help her sleep.”
![Page 5: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/5.jpg)
When it is scenario #3
Many calls you receive will be for non-urgent patient complaints
When called for such complaints, you have several options: Ignore them Be careless Be overly cautious Respond appropriately
It NEVER hurts to go say hi to the patient
![Page 6: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/6.jpg)
Cross-Cover
When on call, many (if not most) of the patients for whom you are responsible will not be YOUR patients.
You must depend upon your colleagues to tell you what you need to know about these patients when they check out
Once your colleagues leave, it’s all YOU
![Page 7: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/7.jpg)
CHECK OUTWhere 102% of all medical errors occur
![Page 8: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/8.jpg)
Check Out List
List of patients on a service Used by on-call person (usually intern)
when called about a patient Often the only information the person on
call will know about the patient Usually includes patient names,
locations, principal diagnoses, and any issues that need to be followed up overnight.
![Page 9: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/9.jpg)
Check Out List
Should also include any other information someone might reasonably need on call Diabetes Renal dysfunction Hepatic dysfunction (cirrhosis) Unstable psychiatric conditions Any medications you want or don’t want
given Known potential for instability/overnight
issues
![Page 10: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/10.jpg)
Check Out
Unless not possible, should also include a face-to-face discussion of
major issues
![Page 11: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/11.jpg)
Check Out- If then statements Crappy checkout: “BMP at 1900” Good checkout:
“BMP at 1700, K was 2.5 and we replaced, if still less than 4.0 give 40 more mEq PO”
Crappy checkout: “Watch this guy’s BP” Good checkout:
“He was hypotensive, responded to 1L NS, I think it was just dehydration but we’ve got abx on board for pneumonia. If he drops again you can give another 1-2L, but if that doesn’t cut it move him to MICU”
![Page 12: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/12.jpg)
Check Out- If then statements Crappy checkout: “This guy is totally
crazy” Good checkout:
“He’s been delirious, probably from this UTI. He responded to haloperidol 1mg IM earlier, no QTc issues, can try this again if need be. Definitely avoid opiates/benzos”
![Page 13: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/13.jpg)
Specific issues on Call
Pain Nausea/Vomiting Insomnia Anxiety Agitation Constipation
Heartburn Pruritus A couple of more
urgent issues Electrolytes
![Page 14: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/14.jpg)
Obviously, for any new, unexpected change in a patient, the first thing to
do is to GO SEE THE PATIENT.
![Page 15: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/15.jpg)
THE “SIMPLE,” “MUNDANE,” AND OFTEN ANNOYING…
![Page 16: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/16.jpg)
Pain-Opiates
Morphine 2.5-5 mg IV May repeat q 4 hrs prn
Oxycodone 5-10mg PO May repeat q 4 hrs prn
Avoid Demerol Increased euphoria, risk of seizures
![Page 17: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/17.jpg)
Conversions of Opiates
Morphine 5mg IV = Morphine 15mg PO = hydrocodone 15mg PO The IV is 3x the PO form
Oxycodone is about twice as potent as PO morphine/hydrocodone
You will get a card that has these details, and if you google “opioid conversion” you get good calculators
![Page 18: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/18.jpg)
Pain-Opiates
Opioids (cont) Dose adjustments
Start with ½ dose in elderly or in renal/hepatic dysfunction
Use caution in patients with respiratory illness May have to use more in patients on chronic
opiates PO:IV conversion for morphine is 3:1
If you give too much, remember: Narcan 0.4mg IV
![Page 19: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/19.jpg)
Pain-Acetaminophen
Acetaminophen The SAFEST for most patients Also good for fever 650mg PO/PR Very safe as long as you give less than 4gm
per day in most people and <2gm/day in cirrhotic patients Probably should avoid in active alcoholics
and certainly for patients w acute alcoholic hepatitis
![Page 20: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/20.jpg)

Pain-Combo drugs
Opioid/acetaminophen combinations Percocet
Oxycodone 5mg/APAP 325mg Vicodin
Hydrocodone 5-10mg/APAP 325mg Many other dose combinations available
Quick rule of thumb: most patients can have 1 percocet 5/325 q4h prn pain and be fine
![Page 23: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/23.jpg)
Pain
NSAIDs AVOID in kidney injury, CKD, cirrhosis, CHF,
ACS and UGIB So avoid them in most of our patients
Naproxen 500mg PO q 12 hrs Ibuprofen 800mg PO q 8 hrs Ketorolac (Toradol) 60mg IM/IV once, then
30mg IV/PO q 6 hrs Cannot use for > 5 days
![Page 24: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/24.jpg)
Nausea/Vomiting
Ondansetron (Zofran) 8mg po or IV q 8 hrs prn Safest side effect profile for elderly Not that expensive anymore, and very
cheap PO now. Should be first line PO nausea medicine
![Page 25: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/25.jpg)
Nausea/Vomiting
Promethazine (Phenergan) 25mg IV/IM q 4 hrs prn 50mg PO/PR q 4 hrs prn Causes sedation, agitation, delirium
NauseaphenergandeliriumbenzofallSDHMICUdeathM and M conference presentation +/- lawsuit
Use lower doses (try half) in elderly due to increased side effects (or just avoid in the elderly)
![Page 26: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/26.jpg)
Nausea/Vomiting
Metoclopramide (Reglan) 10mg IV/PO q 6 hrs prn Remember it stimulates gut motility
Avoid in suspected bowel obstruction or diarrhea
Sedating in some patients Use half dose in dialysis patients or elderly Dystonic reaction
Treat with Benadryl 25-50mg IV
![Page 27: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/27.jpg)

Acute Anxiety
Why is the patient anxious? Actively dying always makes me anxious too.
Keep in mind a common scenario Anxious pt anxious nurse intern gives benzos
code blue anxious program director Short-acting benzodiazepines (very
dangerous) Lorazepam (Ativan)
1-2mg PO/IV q 4-6 hrs prn Alprazolam (Xanax) do not use it Can try trazodone in elderly first, or can try
hydroxyzine if drug-seeking
![Page 32: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/32.jpg)
Anxiety can be from bad things Anxiety + tachypnea = PE, pneumonia,
sepsis, or MI Anxiety + disorientation =
hypoglycemia, delirium, shock, sepsis Anxiety + fever = sepsis Anxiety + fever + tachycardia +
hypotension = severe sepsis nearing death
Anxiety in 25 yo healthy person w normal vitals except heart rate 96 = anxiety
![Page 33: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/33.jpg)
Agitation
This is not a “nuisance call.” Probably is delirium 9 times out of 10 in inpatients 30% of delirium is caused by our drugs. Other
causes include dehydration, shock, hypoglycemia, hyponatremia, and alcohol withdrawal
Worst thing you can do: “Ok, Ms. Jones is a little agitiated, give her ativan 2mg IV now and let me know how she does” If you do that, the code pager will go off before your
personal pager 1 time in 4 Get on the computer and read the notes, check
the vitals, ask yourself if she is a withdrawing alcoholic, if she is hypoglycemic, if she is septic
![Page 34: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/34.jpg)
Agitation
Haloperidol (Haldol) 2mg-5mg PO/IM/IV In elderly, use 0.5-1mg PO/IM/IV Watch for dystonic reaction
Ativan 2mg PO/IV Avoid in confused elderly patients If delirious, then give haldol without benzo.
May need higher dose if patient uses medication chronically
![Page 35: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/35.jpg)
Constipation
Constipation = miralax deficiency
![Page 36: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/36.jpg)

Constipation
Lactulose 30mL PO Can cause bloating/gas Unless they have hepatic enceph, use
miralax instead Bisacodyl (Dulcolax)
10mg PO/PR Can cause cramping
Combinations also work well
![Page 38: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/38.jpg)
Heartburn
MgOH/AlOH (Maalox) 30mL PO Avoid in dialysis patients
CaCO3 (Tums) 2 tablets PO Safe in dialysis patients
Ranitidine (Zantac) 150mg po BID prn Dose once daily in dialysis patients
![Page 39: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/39.jpg)
Heartburn
GI cocktail Usually combination of Maalox, viscous
lidocaine, and another medication (Benadryl or Donnatal)
Usually complicated to order and is delayed by Pharmacy
Some studies say no better than Maalox alone
Do not give PPI alone for acute heartburn Onset of action is delayed by several hours
![Page 40: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/40.jpg)

Chest Pain
“What are his vitals? … Ok, Give him SLNG 0.4mg and call for a stat ECG, troponin now and in 4-6 hours, I’m on the way”
Give nitroglycerin 0.4mg sublingual Response does not predict cardiac source, but
may give the patient relief. Will decrease BP every time
EKG Troponin/cardiac enzymes If no response to NTG x 3 and EKG is negative,
can try Maalox or GI cocktail

Fever
2 Rules: 1) Get blood cultures before starting any
antibiotics 2) Get blood cultures before starting any
antibiotics

Fever
Obtain blood cultures before starting antibiotics
Causes in hospitalized patients: UTI (foley) Pneumonia Wounds (surgical, trauma, decubiti) Plastic (IV’s, CVL’s, drainage catheters, etc.) DVT C. difficile colitis (if diarrhea present) Sinusitis (if NG tube has been used)

Electrolytes
Potassium 10mEq for every 0.1mEq above 3.0 20mEq for every 0.1mEq below 3.0
K 2.8, want to correct to 4.0 (20x2)+(10x10) = 140mEq
![Page 53: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/53.jpg)
Electrolytes
Potassium (cont.) For urgent replacement, give PO powder or
tablets and IV IV rates
10mEq/hr through peripheral 20mEq/hr through CVL
Use caution when replacing patients with chronic kidney disease (but still replace if they need it!)
Be even more careful in dialysis patients, but they still need it.
![Page 54: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/54.jpg)
Electrolytes
Magnesium Safe to give in large amounts
“Symptomatic patients, such as those with tetany, arrhythmias, or seizures should receive intravenous magnesium. Such patients should have continuous cardiac monitoring.”
Can be given quickly Give 2-4g MgSO4 IV, and schedule some PO
(like MgOx 400mg BID or TID) 1gm of Mg sulfate IV = 8 mEq Mg Sulfate IV
Only replace if absolutely necessary in dialysis patients
![Page 55: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/55.jpg)
Electrolytes
Calcium Very dangerous to replace IV. In asymptomatic
patients, should be replaced PO. Calcium carbonate (tums) 1250 PO 4x/day
If low, first check serum albumin: [Measured Ca] + [(4.0 – albumin) x 0.8] = corrected Ca
If replacing, know PO4 first Replacement IV for long QT, Vtach, seizure
Ca gluconate 1 amp (10mL of 10% solution) = 1g 1g Ca gluconate = 4.65 mEq Usual replacement is with 1-2g Ca gluconate IV
![Page 56: Surviving call for Interns](https://reader035.fdocuments.us/reader035/viewer/2022062513/556dbb14d8b42aed2e8b4af0/html5/thumbnails/56.jpg)
Electrolytes
Phosphorus If mildly low (>1.5), replace PO
Neutra-Phos 2 packets BID-TID Milk
If very low or symptomatic, pt needs IV as well Ask for help
Do not replace in dialysis patients unless absolutely necessary
(tired of hearing this yet?)

Sodium
2 rules: All hyponatremic patients should have
serum and urine osmolality drawn Get help to make sure all corrections are
slow
