ImpulseEMT
Airway, Respiration & Ventilation · Question 13 of 20
You find an unresponsive adult with gurgling respirations. What should you do first?
A. Insert an oropharyngeal airway
B. Suction the oropharynx ✓
C. Ventilate with a bag-valve mask ✕
D. Apply a nonrebreather at 15 L/min
Why: Clear the airway before pushing air — ventilating past fluid forces it into the lungs.

Everything in one app

Built to get you exam-ready

Impulse adapts to you — focusing your time on weak areas and mirroring the computer-adaptive format, so test day feels familiar.

Adaptive mock exams

CAT-style practice tests that adjust to your ability and give a pass / borderline / not-yet readiness estimate.

Practice by domain

Drill every exam domain with instant rationales and key teaching points on each answer.

Spaced-repetition flashcards

Term cards that resurface what you miss and space out what you know, so it sticks.

Drug & drip calculators

Weight-based dose, IV drip rate, and Parkland — with built-in practice problems.

Scope of practice

See exactly what falls under each license — and compare just the differences between levels.

Treatment algorithms

Visual, step-by-step flows for 40+ emergencies to lock in the sequence of care.

Progress tracking

Accuracy by domain and clinical-judgment step pinpoints what to study next.

Learn mode & library

Concept refreshers, medication cards, and quick-reference sheets — all in one place.

Works offline

Install it like an app and study anywhere — on the bus, at clinicals, or off the grid.

For every EMS student

One app, all four levels

Switch levels anytime. Each is built to its own current NREMT blueprint and scope of practice.

EMR
Emergency Medical Responder

Foundational BLS care — assessment, CPR/AED, bleeding control, and airway basics.

EMT
Emergency Medical Technician

The core BLS provider — assess, treat, and transport across every phase of care.

AEMT
Advanced EMT

Adds IV/IO access, a limited drug box, supraglottic airways, and basic monitoring.

Paramedic
Paramedic

Full ALS — advanced airway, cardiac care, 12-leads, and a broad medication formulary.

Built for how EMS students actually study

On shift, between classes, or cramming the night before — Impulse fits how you actually have time to study.

Why trust these questions

Written by EMS people, for the exam you're actually taking

We're new, so we won't pretend to have a wall of reviews yet. Judge the questions instead — 40 of them are free, no login.

Original questions, not recalled exam items

Every one of the 6,506 questions is written from scratch against the current NREMT test plan. Nothing here is scraped from a real exam.

Scenario-first

Most questions put a patient in front of you and ask what you do next — not what a term means. That's how the Registry tests, so that's how we write.

Every wrong answer is plausible

Distractors are deliberately hardened. If you can rule one out on grammar or length alone, it's a bad question and we've rewritten it.

The rationale teaches the decision

Answers explain why the right action is right and why each wrong one is tempting — the reasoning transfers to the next patient.
