🩸 ABGs (Arterial Blood Gases) are one of the MOST important concepts in nursing, critical care, and NCLEX preparation. ABGs help nurses evaluate: 🫁 Oxygenation 🫁 Ventilation 🩸 Acid-base balance The normal values every nursing student should know: ✅ pH: 7.35 – 7.45 ✅ PaCO₂: 35 – 45 mm

🚨 Chest pain should NEVER be ignored.

🚨 Chest pain should NEVER be ignored. Not all chest pain is caused by a heart attack… but every patient with chest pain should be taken seriously until a life-threatening cause has been ruled out. 🫀 Chest pain can occur when the heart muscle is not receiving enough oxygen-rich blood due to n

🫀 A pacemaker can be life-saving when the heart’s natural electrical system fails. A pacemaker is a small implanted device that sends electrical impulses to the heart when the heart rate becomes too slow or when conduction pathways are blocked. Think of it as a backup electrical system for th

A-Flutter

⚠️ Atrial Flutter is a common supraventricular dysrhythmia caused by a rapid electrical circuit within the atria. Instead of a normal heartbeat beginning from a single impulse in the SA node, the electrical signal continuously circles through the atria, causing them to contract extremely fast. 🫀

🚨 Third-Degree AV Block (Complete Heart Block) is one of the MOST serious cardiac conduction disorders. In this rhythm, NO electrical impulses from the atria reach the ventricles. 🫀 The atria and ventricles beat independently of each other, creating complete electrical dissociation. What d

Mobitz II

⚠️ Second-Degree AV Block Type II (Mobitz II) is one of the MOST dangerous heart blocks nurses need to recognize. Unlike Wenckebach (Mobitz I), the PR interval does NOT progressively lengthen. Instead: 🧠 The PR interval remains constant 🧠 Electrical conduction suddenly fails 🧠 A QRS comple

Mobitz I

⚠️ Second-Degree AV Block Type I (Mobitz I / Wenckebach) is one of the MOST recognizable heart blocks on an ECG. This rhythm occurs when electrical impulses traveling through the AV node become progressively delayed until one impulse fails to reach the ventricles. 🫀 The result? 🧠 PR interv

V-Tach

🚨 Ventricular Tachycardia (V-Tach) is a LIFE-THREATENING cardiac rhythm. Unlike normal electrical impulses that begin in the atria, V-Tach originates in the ventricles, causing the heart to beat dangerously fast and inefficiently. 🫀 As the ventricles race: ⚠️ cardiac output drops ⚠️ blood p

A-Fib

⚠️ A-Fib is one of the MOST common cardiac dysrhythmias nurses will encounter. Atrial fibrillation happens when chaotic electrical impulses fire rapidly throughout the atria… causing the heart to beat irregularly and often too fast. 🫀 Instead of a smooth organized rhythm: 🚨 the atria begin

Heart cath

🫀 Heart catheterization is one of the MOST important procedures in cardiac care. Also known as cardiac cath or coronary angiography, this minimally invasive procedure allows providers to visualize the coronary arteries and evaluate blood flow to the heart. 🩺 During the procedure: ⚠️ a cathet

Heart attack

🚨 A heart attack is NOT just chest pain. A myocardial infarction happens when blood flow through a coronary artery becomes blocked, preventing oxygen from reaching part of the heart muscle. 🫀 As blood flow decreases: ⚠️ heart tissue becomes ischemic ⚠️ oxygen delivery drops ⚠️ heart muscle

🚨 Hypothyroidism slows down the entire body.

When the thyroid gland does not produce enough thyroid hormones (T3 & T4), the body’s metabolism begins slowing down over time. 🩺 That’s why patients may develop: ⚠️ fatigue ⚠️ weight gain ⚠️ cold intolerance ⚠️ dry skin ⚠️ constipation ⚠️ slowed heart rate ⚠️ depression & mental

thyroid gland

🦋 The thyroid gland may be small… but it controls some of the MOST important functions in the body. Located in the front of the neck, the thyroid produces hormones (T3 & T4) that regulate: ⚡ metabolism ⚡ energy production ⚡ heart rate ⚡ body temperature ⚡ growth & development Wh

UTI

🚨 A UTI may seem “minor”… until the infection starts spreading. What begins as: ⚠️ burning with urination ⚠️ urgency ⚠️ urinary frequency ⚠️ lower abdominal discomfort can quickly progress into: 🚨 kidney infection 🚨 fever & chills 🚨 flank pain 🚨 sepsis 🚨 systemic complications

CHF

🫀 CONGESTIVE HEART FAILURE looks simple in textbooks… until you truly understand what’s happening inside the heart. In CHF, the heart slowly loses its ability to pump blood effectively. As pressure builds, the chambers begin to stretch and enlarge — especially the LEFT VENTRICLE, which becomes
