اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Bradycardia means a slow heart rate .
Normal adult resting heart rate i s 60–100 beats/min .
A heart rate below 60 bpm is clinically termed bradycardia.
It may be physiological (e.g., athletes) or pathological .
Can cause symptoms like dizziness, fatigue, or syncope if severe.

Cystic duct
Urinary Bladder
Gallbladder
Cerebrospinal fluid cistern
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The suffix “-itis” means inflammation .
“Cyst” refers to the urinary bladder .
Cystitis commonly results from a urinary tract infection (UTI) .
Symptoms include burning urination and frequency .
It doe s not involve the gallbladder or ducts .

Common Hepatic Artery
Caliac trunk
Splenic artery
Cystic Artery
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The gastroduodenal artery supplies blood to the stomach (antrum) and duodenum .
It arises as a branch of the common hepatic artery , which itself is a branch of the celiac trunk .
The celiac trunk gives three main branches : left gastric, splenic, and common hepatic arteries .
Splenic artery mainly supplies the spleen and pancreas, not the gastroduodenal artery .
Cystic artery supplies the gallbladder, not the stomach or duodenum.

Indirect transmission
Direct transmission
Common vehicle transmission
Airborne transmission
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Transmission via an intermediate organism (vector) like a mosquito is called vector-borne transmission .
The pathogen does not move directly from person to person .
The vector (mosquito) carries and transmits the disease (e.g., malaria, dengue).
Direct transmission involves person-to-person contact (touch, droplets).
Common vehicle and airborne transmission involve contaminated food, water, or air, not a living vector.

Locate and provide aid to people in immediate danger
Provide definitive medical care on site
Restore utility services
Control public crowd
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The primary purpose of Urban Search and Rescue (USAR)
Ur is to find, access, and rescue victims who are trapped or in life-threatening situations ,
Provide initial lifesaving care until they can be safely evacuated.
Provide definitive medical care on site → not the main role of USAR
Restore utility services → handled by public works/utility agencies
Control public crowd → responsibility of law enforcement

Nasal Irrigation
Antral Lavage
Tracheal Suction
Bronchial Washing
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Nasal irrigation is the process of cleaning the nasal passages by gently flowing a s olution (usually saline) in and out of the nose to remove mucus, allergens, and debris.
Antral lavage → washing of the maxillary sinus

3 Hours
24 Hours (The Golden Day)
72 Hours
96 Hours
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The first 72 hours are called the Golden 72 Hours .During this window, trapped victims have the highest probability of survival because
Survival Rates: Research indicates survival rates are approximately 90% within the first 24 hours, but drop significantly to 50–60% by 48 hours, and 20–30% by the 72-hour mark. Physiological Limits: This timeframe aligns with the general biological limit o f human survival without water and food. Resource Delays: Professional search and rescue (SAR) t eams often take time to mobilize

Epiglottitis
Asthma
FBAO
None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A child with respiratory distress , high-pitched inspiratory sound (stridor) , drooling , and t ripod positioning is classic for epiglottitis .
Asthma → expiratory wheeze, no drooling
FBAO (foreign body airway obstruction) → sudden choking episode, not typically drooling with tripod posture

It is avascular (lacks blood vessels)
It contains primarily elastic fibres
It is highly innervated
It resist calcification throughout
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Hyaline cartilage is the most common type of cartilage (e.g., trachea, nose, articular surfaces).
It does not contain blood vessels , nerves, or lymphatics (avascular and aneural).
Nutrients reach it by diffusion from surrounding tissues.
It contains fine collagen fibers , not elastic fibers (those are in elastic cartilage).
Hyaline cartilage can calcify with age , so it does not resist calcification permanen

Airway, Breathing and Circulation (e.g Blood Pressure, Oxygenation)
Skin Integrity
Serum Electrolyte
Hourly Urine Output
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Pulmonary edema causes fluid in the lungs, leading to impaired breathing and low oxygen levels .
In emergencies, assessment follows the ABC principle (Airway, Breathing, Circulation).
Airway and breathing must be ensured first to prevent hypoxia and respiratory failure.
Circulation (blood pressure, heart rate) is critical in a patient with heart failure .
Skin integrity, electrolytes, and urine output are important, but they are s econdary priorities after stabilizing ABCs.
