Which medical imaging technique uses a powerful magnetic field and radio waves to generate detailed images of the organs and tissues within the body?
- A X-ray (Radiography)
- B CT Scan (Computed Axial Tomography)
- C MRI (Magnetic Resonance Imaging)
- D Ultrasound (Sonography)
Correct answer: MRI (Magnetic Resonance Imaging)
Magnetic Resonance Imaging (MRI) does not use ionizing radiation, unlike X-rays and CT scans. It is particularly useful for imaging soft tissues such as the brain, muscles, and heart.
The 'Sphygmomanometer' is a medical instrument used by healthcare professionals to measure which of the following?
- A Body Temperature
- B Blood Pressure
- C Heart Rate
- D Blood Glucose
Correct answer: Blood Pressure
A sphygmomanometer consists of an inflatable cuff, a measuring unit, and a mechanism for inflation. It measures the force of blood against the walls of the arteries in both systolic and diastolic phases.
Which inventor is credited with the development of the first practical and widely used 'Stethoscope' in 1816?
- A René Laennec
- B Louis Pasteur
- C Joseph Lister
- D Robert Koch
Correct answer: René Laennec
René Laennec invented the wooden monaural stethoscope because he was uncomfortable placing his ear directly on a female patient's chest. This invention revolutionized the diagnosis of chest conditions by allowing doctors to hear internal sounds clearly.
In medical technology, what does the acronym 'LASIK' stand for in the context of eye surgery?
- A Laser-Activated Skin Keratotomy
- B Laser-Assisted In Situ Keratomileusis
- C Light-Amplified Skin Incision Knife
- D Laser Ablation of Surface Iris Keratin
Correct answer: Laser-Assisted In Situ Keratomileusis
LASIK is a type of refractive surgery used to correct myopia, hyperopia, and astigmatism. It involves using a laser to reshape the cornea to improve how the eye focuses light onto the retina.
Which life-saving device is designed to deliver an electric shock to the heart to restore a normal rhythm during sudden cardiac arrest?
- A Ventilator
- B Defibrillator
- C Dialysis Machine
- D Pulse Oximeter
Correct answer: Defibrillator
Defibrillators, including Automated External Defibrillators (AEDs), stop an irregular heart rhythm (arrhythmia) like ventricular fibrillation. This momentary stop allows the heart's natural pacemaker to re-establish a functional rhythm.
The 'Iron Lung', a large machine that helps patients breathe by varying air pressure, was most famously used to treat victims of which disease?
- A Tuberculosis
- B Mumps
- C Polio
- D Influenza
Correct answer: Polio
The iron lung was a form of non-invasive negative-pressure ventilator widely used during the polio epidemics of the mid-20th century. It mechanically moved the chest muscles of patients whose respiratory systems were paralyzed by the virus.
Which diagnostic tool uses high-frequency sound waves to view real-time images of internal organs and is commonly used during pregnancy?
- A Endoscope
- B PET Scan
- C Ultrasound
- D Thermograph
Correct answer: Ultrasound
Ultrasound technology works by bouncing sound waves off internal structures to create an image (sonogram). Because it does not use radiation, it is considered safe for fetal monitoring and examining soft tissues.
The process of 'Hemodialysis' is a medical technology used to perform the primary functions of which organ when it fails?
- A Liver
- B Pancreas
- C Kidney
- D Lungs
Correct answer: Kidney
Hemodialysis uses a machine and a special filter called a dialyzer to clean the blood of toxins, extra salt, and water. It is essential for patients with end-stage renal disease to maintain chemical balance in the body.
Who was the first person to discover X-rays in 1895, earning the first-ever Nobel Prize in Physics?
- A Marie Curie
- B Henri Becquerel
- C Ernest Rutherford
- D Wilhelm Röntgen
Correct answer: Wilhelm Röntgen
Röntgen discovered X-rays while experimenting with cathode rays in a vacuum tube. He famously produced an image of his wife's hand, showing the bones and her wedding ring, marking the birth of diagnostic radiology.
A 'Pulse Oximeter' is a non-invasive device used to measure the heart rate and the level of which substance in the blood?
- A Carbon Dioxide
- B Blood Glucose
- C Iron Content Level
- D Oxygen Saturation
Correct answer: Oxygen Saturation
The device clips onto a finger or earlobe and uses light absorption to determine the percentage of hemoglobin loaded with oxygen. It became a critical tool for monitoring respiratory health during the COVID-19 pandemic.
Which surgical technology allows doctors to perform complex procedures with more precision, flexibility, and control than is possible with conventional techniques?
- A Laparoscopic Surgery
- B Cryosurgery
- C Acupuncture
- D Robotic Surgery
Correct answer: Robotic Surgery
Robotic-assisted surgery uses miniaturized instruments and high-definition 3D cameras controlled by a surgeon from a console. It allows for minimally invasive procedures with smaller incisions and faster recovery times.
What is the primary function of an 'Electrocardiogram' (ECG or EKG)?
- A To measure brain wave activity
- B To monitor muscle contractions
- C To check for bone density and mineral content
- D To record the heart's electrical activity
Correct answer: To record the heart's electrical activity
An ECG records the timing and strength of electrical signals as they travel through the heart. It is used to detect heart attacks, arrhythmias, and other cardiac abnormalities.
The 'Pacemaker' is an implanted medical device used primarily to treat which condition?
- A Hypertension
- B Diabetes
- C Epilepsy
- D Bradycardia
Correct answer: Bradycardia
A pacemaker sends small electrical impulses to the heart muscle to maintain a suitable heart rate. It prevents the heart from beating too slowly, which could otherwise cause fainting or fatigue.
In laboratory technology, the 'PCR' technique is used to amplify small segments of DNA. What does PCR stand for?
- A Polymerase Chain Reaction
- B Protein Catalytic Reaction
- C Primary Coding Reagent
- D Pathogen Control Record
Correct answer: Polymerase Chain Reaction
Developed by Kary Mullis, the Polymerase Chain Reaction allows scientists to take a tiny sample of DNA and produce millions of copies. It is fundamental to genetic testing, forensics, and infectious disease diagnosis.
Which medical device is used to maintain a constant flow of air into the lungs of a patient who is unable to breathe on their own?
- A Nebulizer
- B Inhaler
- C Oxygen Concentrator
- D Ventilator
Correct answer: Ventilator
Ventilators move breathable air into and out of the lungs, providing the mechanism of breathing for patients with respiratory failure. They can be invasive (via a tube) or non-invasive (via a mask).
The 'Glucometer' is a portable device used by patients, particularly those with diabetes, to monitor their levels of:
- A Blood Sugar
- B Cholesterol
- C Urea
- D Calcium
Correct answer: Blood Sugar
A glucometer analyzes a small drop of blood, usually obtained by pricking the finger. It provides an immediate reading of the glucose concentration in the blood, helping patients manage their insulin levels.
Which imaging technology uses 'Positrons' to look for chemical activity in organs and tissues, often used to detect cancer?
- A PET Scan
- B CT Scan
- C X-ray
- D Fluoroscopy
Correct answer: PET Scan
Positron Emission Tomography (PET) scans involve injecting a radioactive tracer that collects in areas of high chemical activity. Because cancer cells have a higher metabolic rate, they show up as 'bright spots' on the scan.
What is the function of an 'Endoscope' in medical practice?
- A To look inside a body cavity or organ
- B To record heart sounds
- C To measure lung capacity
- D To deliver targeted radiation therapy
Correct answer: To look inside a body cavity or organ
An endoscope is a long, thin, flexible tube with a light and camera at the tip. It allows doctors to view the digestive tract, lungs, or other internal areas without making large surgical incisions.
The invention of the 'Ophthalmoscope', used to examine the interior of the eye including the retina, is credited to whom?
- A Hermann Helmholtz
- B Isaac Newton
- C Charles Darwin
- D Gregor Johann Mendel
Correct answer: Hermann Helmholtz
Hermann von Helmholtz invented the ophthalmoscope in 1851. It enabled physicians to see the fundus of the eye clearly for the first time, revolutionizing the field of ophthalmology.
Which medical technology involves using a machine to take over the work of the heart and lungs during open-heart surgery?
- A Cardiopulmonary Bypass
- B Dialysis
- C Extracorporeal Shock Wave Lithotripsy
- D Intubation
Correct answer: Cardiopulmonary Bypass
The heart-lung machine maintains the circulation of blood and the oxygen content of the body while the heart is intentionally stopped for surgery. It bypasses the heart and lungs entirely to provide a still field for the surgeon.
