41 y/o pt in the SICU following debridement of b/l lower
extremities for necrotizing fasciitis is intubated on AC.
Temp 102, HR 116, RR 16, BP 92/46. ABG shows pH 7.23,
PO2 133, PCO2 38, Na 139, K 3.7, Cl 102, Bicarb 16, lactate
4. Dx is metabolic acidosis w/ anion gap d/t infection.
What is the most appropriate intervention?
Increase VT
Continue resuscitation
Decrease RR
Administer bicarb - correct answer- Continue
resuscitation. Don't need to increase VT bc the pt doesn't
have respiratory acidosis. If you decrease the RR, the pt
will go into respiratory acidosis.
,A 22 y/o pt ingested drugs >4 hours ago. She came to the
ICU obtunded w/ arousal to tactile stimulation. She is
hemodynamically stable. RR 8 with an NG tube in place.
What is the next step for tx of the ingestion? - correct
answer- Monitor / watchful waiting.
The pt ingested the drugs more than 4 hours ago. Monitor
RR and intubate if necessary.
A 24 y/o male comes in following a concussion. CT reveals
a frontal lobe contusion. He does not require intubation
and is kept on 3 L O2 NC. He then suddenly has a
generalized seizure.
What is the DOC?
What do you give after the seizure?
What med class is an absolute contraindication for
seizures? - correct answer- 1. lorazepam IV
, 2. dilantin
3. NMB
A 50 y/o pt is having a COPD exacerbation. You have tried
steroids, bronchodilators, etc. with no improvement.
PCO2 is in the 90s, pH is 7.20. You decide to intubate.
Vent settings are: VT 375, RR 20, FiO2 .35, PEEP 5. CXR is
normal. A few minutes later, his BP drops to 70/40. Lungs
are clear/equal. Vent shows peak airway pressure of 55
(high) and plateau pressure of 15. End expiratory hold
gives auto-peep of 15.
What is the cause of this pt's HoTN and why? -
correct answer- Auto-peep is the cause.
COPD pts have difficulty exhaling --> pressure buildup in
alveoli.
We use PEEP for the pressure and to improve
oxygenation. Auto-peep comes from breath-stacking -->
