2025 ACTUAL EXAM COMPLETE 54 QUESTIONS

AND CORRECT DETAILED ANSWERS (VERIFIED

ANSWERS). GRADED A

1st step in respiratory arrest while ON the vent - ANSDisconnect them from the vent 3 types of vent cycles - ANSVolume (preset tidal volume, relieves WOB the most) Time (constant pressure of time) Flow (constant pressure until inspiratory flow is below 25% of peak) ABG findings in PE - ANSDecreased CO2 (hyperventilating) Decreased O2 (V/Q mismatch) ACE-I in pregnancy - ANSNO Airway in hematemesis pt - ANSElectively intubate it Assist-control ventilation - ANSEither volume or time cycled breaths given Usually the go to when you just started someone on the vent Gives the pt a set tidal volume and preset flow rate respiratory rate. Very rigid. However, if the patient wants to take extra breaths if they trigger them.

AutoPEEP (what it is, what it causes, how to fix it) - ANSBreath stacking Decreases preload to the heart with positive pressure on the lungs --> hypotension Decrease RR, decrease inspiration time (goal is to have more time for the lungs to exhale) c - ANSHypoxemic (PaO2 <50-60) Hypercapnic (PaCO2 >50, pH <7.36) Mixed C diff abx - ANSFlagyl CAP immunocompromised pt (tx) - ANSBactrim CAP tx - ANSbeta-lactam and macrolide OR fluoroquinolone CPP goal in TBI (and how to calculate it) - ANS50- MAP - ICP Danger of increased PEEP - ANSIncreases autoPEEP, increases Pplat Delta gap (formula, when and why it's used) - ANSDifference in AG from normal - Difference in HCO3 from normal

In AG metabolic acidosis it's used. It tells you if there's underlying metabolic alkalosis or respiratory acidosis with bicarb compensation IN ADDITION to the AG metabolic acidosis. Both of those would result in a high bicarb to begin with, and a smaller change in bicarb from normal. Endocarditis bugs - ANSStrep viridans and other streps, staph GI change in pregnancy - ANSLES tone decreases, increasing the risk of aspiration Goal FiO2 on vent - ANSStart at 1.0, then decrease as SpO2 tolerates (goal of 92- 94 saturation) Goal tidal volume - ANS10 cc/kg HCAP tx - ANSvanc/zosyn HELLP vs preeclampsia tx - ANSDelivery vs Mg Hemodynamic changes after intubation - ANSHypo/hypertension Arrhythmia Tachycardia

How AG changes with albumin changes - ANSDecreases 2.5-3 for every 1 decrease in albumin Intraabdominal HTN (criteria, effects) - ANS>12 mmHg End organ damage and decreased preload to heart causing hypotension Lovenox class - ANSLMWH Manual decompression (when you use it) - ANSIf patient is air trapping like crazy on the vent, and you disconnect it and push up on the patients diaphragm to get everything out Most important indicator that a patient has a severe illness? - ANSTachypnea Necrotizing fasciitis tx - ANSvanc/zosyn clindamycin Neutropenic fever abx - ANSThink G-, so cefepime PaO2 we're usually happy with - ANS> Peripartum cardiomyopathy - ANSlate in gestation incurable presents like CHF

Ppeak - ANSPeak inspiratory pressure Pplat (try to keep it below ?) - ANSInspiratory plateau pressure (shows alveolar distention) 30 Preeclampsia - ANS20+weeks, HTN, proteinuria/edema Pregnancy pyelo tx - ANSceftriaxone Pressure assist-control breath (time cycled) - ANSVent delivers a constant pressure over a preset time Pressure support breath (flow cycled) - ANSSame as pressure assist-control breaths, but the vent cuts out when the flow rate decreases to 25% of initial peak flow rate Pressure support equation for BiPAP - ANSIPAP - EPAP Pressure support ventilation - ANSWaits for patient to start breath, and then helps out with a set amount of pressure SAH tx - ANSnimodipine to stop vasospasm and control BP SBP abx - ANSceftriaxone flagyl

Sepsis vs severe sepsis vs septic shock - ANSYou know vs End organ damage vs Resistant to tx SVT tx - ANSAdenosine Synchronized intermittent mandatory ventilation - ANSSIMV Delivers volume or time cycled breaths at a mandatory rate Patient can breathe spontaneously between mandatory breaths Spontaneous breaths count - this allows the patient to contribute to the mandatory tidal volume the machine requires them to breathe Tx of an inferior MI - ANSNO nitroglycerin Give fluids instead Tx of HTN urgency vs emergency - ANSNo drip vs drip Volume assist-control breath (Volume cycled) - ANSVent delivers preset tidal volume What a high A-a gradient means - ANSV/Q mismatch

When do you give tPA in ACS? - ANSONLY for a STEMI, and ONLY when PCI isn't readily available When hypothermia helps (disease) - ANSV fib When to consider NPPV vs invasive - ANSWhen it's a quickly solved problem in 1- days (e.g. COPD exacerbation) When the patient can be compliant with working with NPPV When to consider switching from NPPV to invasive ventilation support - ANSIf things aren't really improving in a matter of hours If your therapeutic goals haven't been met in 4-6 hours When to give tPA in PE - ANSOnly for huge ones and heparin's not working Wide complex tachycardia tx - ANSAmiodarone Winter's formula (equation, what it measures) - ANS1.5[HCO3] + 8 +/- 2 If compensation is adequate in acid/base issues
