🤰🩸 PLACENTA — Essential Nursing & Midwifery Notes!

The placenta is a temporary organ that supports fetal growth and development throughout pregnancy.

🩺 Key Functions of the Placenta:

🫁 Respiratory: Exchanges oxygen and carbon dioxide.

🥗 Nutritional: Transfers essential nutrients to the fetus.

🩸 Excretory: Removes fetal metabolic waste.

🌸 Endocrine: Produces hCG, progesterone, oestrogens and human placental lactogen.

🛡️ Immunological: Transfers maternal IgG antibodies for passive immunity.

🔬 Placental Development:

Fetal part — Chorion frondosum

Maternal part — Decidua basalis

💡 Remember: Maternal and fetal blood normally remain separate, with substances exchanged across the placental barrier.

🧠🚨 Increased Intracranial Pressure (ICP) – Early vs Late Warning Signs!

Every nurse should recognise the warning signs of increased ICP to prevent serious brain injury! 🩺

🟢 Early Warning Signs:
✅ Headache
✅ Confusion or restlessness
✅ Nausea and vomiting
✅ Blurred vision
✅ Increasing drowsiness

🔴 Late Warning Signs:
⚠️ Reduced consciousness
⚠️ Abnormal pupils
⚠️ Abnormal posturing
⚠️ Irregular breathing
⚠️ Cushing’s triad

💡 NCLEX-RN Tip: A change in level of consciousness is an important early warning sign!

🚨 Never wait for Cushing’s triad before escalating neurological deterioration.

💉 5 IV Cannula Complications Every Nurse Must Know! 🩺

An IV cannula is commonly used in clinical practice, but complications can occur if the site is not monitored properly.

🚨 Remember these 5 complications:

1️⃣ Phlebitis – Inflammation of the vein
2️⃣ Infiltration – IV fluid leaks into surrounding tissue
3️⃣ Extravasation – Tissue-damaging medication leaks into tissue
4️⃣ Infection – Infection at the cannula site
5️⃣ Occlusion – Blocked IV cannula

⚠️ Important Nursing Tip: Never ignore pain, swelling, redness or burning at an IV site. Stop the infusion, assess immediately and follow your local protocol.

🤰 PRETERM LABOUR — Essential Nursing & Midwifery Notes! 👶🩺

Preterm labour occurs before 37 completed weeks of pregnancy, with regular uterine contractions and cervical changes.

🔍 Common Risk Factors: ✅ Previous preterm birth ✅ Multiple pregnancy ✅ Short cervix ✅ Maternal infections ✅ Preterm rupture of membranes

🚨 Warning Signs: 🔸 Regular uterine contractions 🔸 Lower backache and pelvic pressure 🔸 Menstrual-like cramps 🔸 Vaginal bleeding or watery discharge

💊 Management May Include: 💉 Antenatal corticosteroids — Support fetal lung maturation. 💊 Tocolytics — May temporarily delay labour. 💉 Magnesium sulfate — Fetal neuroprotection. 🏥 Maternal and fetal monitoring.

👩‍⚕️ Nursing Priority: Recognise warning signs early, monitor maternal and fetal wellbeing, administer prescribed treatment and escalate concerns promptly.

💡 Remember: Preterm labour does not always result in preterm birth!

🫁 Surfactant Release at Birth — Neonatal Nursing Notes 👶

Did you know that pulmonary surfactant helps newborn babies breathe easily after birth?

🩺 What is surfactant? Pulmonary surfactant is a mixture of phospholipids and proteins produced by Type II pneumocytes in the lungs.

✅ Reduces surface tension inside the alveoli. ✅ Prevents alveolar collapse (atelectasis). ✅ Improves lung expansion and gas exchange. ✅ Reduces the effort needed for breathing.

👶 At Birth: Hormonal changes and lung aeration help support surfactant secretion and effective breathing.

🚨 Clinical Point: Surfactant deficiency is a major cause of neonatal respiratory distress syndrome (RDS), particularly in premature babies.

💡 Remember: Surfactant = Keeps alveoli open + Makes breathing easier!

❤️🚨 HYPERKALAEMIA — 5 ECG CHANGES EVERY NURSE MUST KNOW! 🩺

Can you recognise the ECG changes caused by high potassium levels? 👩‍⚕️

Hyperkalaemia occurs when potassium (K⁺) levels in the blood become elevated. Severe hyperkalaemia can cause life-threatening cardiac arrhythmias and cardiac arrest.

📚 5 IMPORTANT ECG CHANGES

1️⃣ Tall, Peaked T Waves
✅ Tall, narrow, tent-shaped T waves
✅ Classic early ECG finding

2️⃣ Prolonged PR Interval
✅ Delayed electrical conduction
✅ PR interval becomes longer

3️⃣ Flattened or Absent P Waves
✅ P waves become smaller
✅ May disappear in severe cases

4️⃣ Widened QRS Complex
✅ Ventricular conduction slows
✅ Broad QRS complexes indicate serious cardiac risk

5️⃣ Sine-Wave Pattern 🚨
✅ QRS and T waves merge
✅ Pre-arrest emergency requiring immediate treatment!

🧠 EASY MEMORY TRICK

T → P → PR → QRS → SINE

🚨 IMPORTANT NURSING PEARL:

A patient can have dangerously high potassium even with a NORMAL ECG!

ECG changes do not always appear in a predictable order.

💉 EMERGENCY MANAGEMENT — REMEMBER 3 STEPS

❤️ PROTECT THE HEART
IV calcium, when indicated, stabilises the myocardium.

💙 SHIFT POTASSIUM INTO CELLS
Insulin with glucose; nebulised salbutamol may be used as an adjunct.

💚 REMOVE POTASSIUM
Potassium binders or dialysis when indicated.

All emergency treatments must follow prescribed orders and local protocols.

👩‍⚕️ NURSING STUDENTS — QUICK QUESTION!

💬 Which ECG change is classically associated with early hyperkalaemia?

A. ST elevation
B. Tall, peaked T waves
C. U waves
D. Shortened PR interval
