MICN Pre-Test Ultimate Exam Question Bank &
Advanced Protocol Study Guide
The Mobile Intensive Care Nurse (MICN) Pre-Test high-yield preparation
guide is a crucial clinical resource designed for emergency department
registered nurses transitioning into prehospital medical direction roles.
Candidates master essential advanced life support (ALS) protocols, fluid
management mechanics, telemetry interpretation, and proper field
delegation rules under county emergency medical services authorities.
Utilizing this expert-verified study bank equips you with realistic diagnostic
questions, telemetry triage breakdowns, and full logical rationales to
ensure you secure a passing score on your first attempt
Starling's Law - ,,,answer,,,..Over-stretching of ventricles can
worsen contractility like a worn out rubber-band
Define Inotropy - ,,,answer,,,..Force of Contraction (contractility)
Define Chronotropy - ,,,answer,,,..Heart Rate
Define Atherosclerosis - ,,,answer,,,..BLOCKAGE in the blood
,vessels caused by plaque deposits
Define Ischemia - ,,,answer,,,..Tissues lack of adequate perfusion
of blood
Define Angina Pectoris - ,,,answer,,,..Chest pain caused by
ischemia
Define Myocardial Infarction - ,,,answer,,,..Death of Cardiac Muscle
Tissue caused by ischemia
Define Preload - ,,,answer,,,..amount of blood delivered during diastole,
dependent on venous return. Greater Preload, greater the stroke volume
Define Afterload - ,,,answer,,,..resistance against which ventricles
must contract, determined by peripheral vascular resistance.
QRS Complex on EKG - ,,,answer,,,..Contraction of heart muscle
T Wave on EKG - ,,,answer,,,..Resting phase or repolarization
2 valves that open during systole when ventricles contract -
,,,answer,,,..Aortic and Pulmonic Valves
,2 valves that open in diastole when ventricles fill -
,,,answer,,,..tricuspid and bicuspid (mitral)
State if Coronary Artery Perfusion occurs during systole or diastole -
,,,answer,,,..Diastole (when heart is not contracting)
Changes in Heart Rate affect Cardiac Output - ,,,answer,,,..if rate is too
slow or too fast, diastolic filling time will be altered decreasing stroke
volume and cardiac output
Define 3 Body Fluid Compartments - ,,,answer,,,..1. Extracellular - body
fluid outside the body's cell
2. Intracellular - body fluid inside the body's cell
3. Intravascular - body's fluid outside the body's cell and within the
circulatory system.
Define Osmosis - ,,,answer,,,..Movement of Fluid across semipermeable
membrane from lesser solute to greater solute concentration. Dilutes
concentrations back to homeostasis
Define Diffusion - ,,,answer,,,..Exchange of gases across a
membrane
, Describe Fluid Shift when administered IV: Isotonic, Hypertonic, Hypotonic
- ,,,answer,,,..1. Isotonic - no fluid shift due to same concentration of blood
stream.
2. Hypertonic - fluid drawn into intravascular space from cells.
3. Hypotonic - fluid enters cell due to decreased osmotic pressure and
decreased concentration.
2 Requirements of cellular function - ,,,answer,,,..Oxygen and
Glucose
What electrolyte predominates intra-cellular -
,,,answer,,,..Potassium
What electrolyte predominates extra-cellular - ,,,answer,,,..Sodium
Electrolyte that moves out during depolarization -
,,,answer,,,..Potassium, while sodium moves in via the "sodium potassium
pump"
Anaerobic Metabolism and its end product - ,,,answer,,,..cellular
metabolism that occurs WITHOUT oxygen, producing lactic acid
Aerobic Metabolism and its end product - ,,,answer,,,..cellular
metabolism that occurs WITH oxygen, producing carbonic acid
