Critical care paramedic ExamQuestions and Answers 2024
When should you perform the intubation during RSI? - -When the waveform
etco2 is flat- meaning the NMBA is working and the diaphragm has stopped.
-Nitrogen washout - -Apply high flow 02 to prepare for intubation and
washout the N2.
-Who gets atropine during RSI and why? - -Pediatric patients <2-3 y/o prior
to RSI. Pediatric patients cardiac output is rate dependent. Pediatric patients
are not able to raise inotropy. Atropine will help prevent with bradycardia.
-Atropine dose - -0.02 mg/kg. Max dose: 0.5 mg
-What can you do if pediatric patient has Low BP prior to RSI? - -administer
vasopresssors
-Lidocaine RSI dose - -1.0- 1.5 mg/kg IV
-What is lidocaine used for in RSI? - -For patients with suspected increased
ICP. Lidocaine will decrease vagal nerve stimulation. It will cause blunting of
the airway reflexes and prevent coughing, gagging, which will raise ICP.
-What are the drug options for sedation in RSI? - -Etomidate, Versed,
Ketamine, and propofol
-Etomidate dose - -0.2-0.3mg/kg
-What is the preferred drug for sedation in RSI? - -Etomidate. Has rapid
onset of 10-20 seconds, short duration of 4-10 mins, can be used in peds,
has no histamine release.
-What are the downsides to giving etomidate for RSI? - -Causes a mild
increase in airway resistance, Myoclonus may be seen, and you must avoid
in septic patients.
-Why can you not give etomidate for septic patients? - -Causes
Adrenocortical supression
-Dose for Versed in RSI? - -2.5-5.0 Mg Iv or .1-.3 mg/kg.
Has a rapid onset of .5- 2 mins, and a short duration of 20-30 mins.
Pediatric infusion dose: 0.05-0.4mg/kg per hour
, -Ketamine dose for RSI? - -1.5-4.0 mg/kg IV over 1 minute ( 5-10 mg/kg IM)
-When is ketamine preferred? - -In pediatrics due to halluciations
-What receptors does ketamine stimulate? - -Stimulates the opiod receptor
causing analgesia.
Will stimulate the catecholamine receptors and release cateccholamines
leading to increased HR, contractility, MAP, and BP.
-Does ketamine increase ICP? - -No evidence shows that ketamine increases
ICP in hypotensive or normotensive patients.
Best not to give ketamine in patients who have suspected IC with high blood
pressure.
-Propofol dose - -Continued sedation dose: 5-50 mcg/kg/min
-Propofol contraindications - -OB and < 8 year old peds
-What effects will propofol have on the body? - -Will lower the BP. Will
reduce airway resistance and can be useful inducting patients with
bronchospasm.
-Is propofol an analgesic? - -No it has sedation and amnesia properties
-Is propfol good for patients with intracranial pathology? - -Yes, if they are
stable.
-What side effects can all neuromuscular blocking agents cause? - -They all
can cause Low BP and Malignant hyperthermia.
-Succinylcholine dose - -1-1.5 mg/kg
Higher doses may reduce occurance of myalgia.
-Only FDA approved depolarizing NMBA? - -Succinylcholine
-Pediatric dose for succs? - -2.0mg/kg
-Contraindications for succs? - -Hyperkalemia, burns >72 hours, < 1 year
eye injuries, glaucoma, MH, paraplegia, MD
-Will succs cause an icrease in ICP? - -No it will not
-Onset and duration of succs? - -Rapid onset - 3-5 mins
Duration- 25-30 mins
-How much can succs raise your serum potassium levels? - -3.0-5 meq/L
