UNTH Internship Exam Past Questions and Answers
As a dedicated medical professional and educator, Dr. Manny from Manny Spark is committed to guiding Nigerian medical graduates through the challenging yet rewarding path to securing an internship at one of the country’s most esteemed institutions. The University of Nigeria Teaching Hospital (UNTH) internship exam represents a critical gateway for aspiring doctors, testing not just rote knowledge but the ability to apply medical principles in real-world scenarios. This Computer-Based Test (CBT) has evolved over the years to align with global standards, emphasizing core competencies in anatomy, physiology, biochemistry, pathology, surgery, medicine, obstetrics, gynecology, pediatrics, and more.
In Nigeria’s competitive healthcare landscape, where thousands vie for limited spots, preparation is paramount. “The UNTH exam isn’t merely a hurdle; it’s a forge that shapes resilient physicians ready to tackle Nigeria’s health challenges,” shares Dr. Manny, founder of Manny Spark, a brand synonymous with empowering medical students through accessible, high-quality resources. This extensive guide, crafted with an educational lens, delves into every facet of the exam— from its historical context to intricate sample questions— all while highlighting UNTH’s unique offerings in Enugu. Whether you’re from Lagos, Abuja, or Port Harcourt, this article equips you with the tools to excel.

A Legacy of Excellence in Nigerian Healthcare
The University of Nigeria Teaching Hospital (UNTH), often hailed as a cornerstone of medical education in West Africa, was founded in 1970 as an extension of the University of Nigeria, Nsukka. Situated in Enugu State, it has grown from a modest facility into a tertiary healthcare powerhouse, serving over 5 million people annually from Nigeria’s South-East region and neighboring countries like Cameroon and Benin Republic. UNTH’s mission— to provide top-tier patient care, education, and research— resonates deeply in a nation grappling with infectious diseases, maternal mortality, and non-communicable illnesses.
Under Dr. Manny‘s guidance at Manny Spark, we’ve seen countless students transform their UNTH aspirations into reality. “Education is the bridge to opportunity, especially in medicine where lives hang in the balance,” emphasizes Dr. Manny. The internship program, a mandatory one-year rotation for MBBS graduates per the Medical and Dental Council of Nigeria (MDCN), immerses interns in multidisciplinary teams, honing skills that extend beyond textbooks.
UNTH’s accreditation by the West African College of Surgeons and Physicians underscores its prestige. Beyond internships, it offers residency programs in over 20 specialties, postgraduate diplomas in nursing, and community outreach initiatives like free immunization drives in Enugu’s rural areas. For Nigerian aspirants, UNTH represents stability: competitive stipends (around ₦150,000-₦200,000 monthly, adjusted for inflation as of 2025), housing options, and exposure to cutting-edge technologies like MRI scanners and robotic surgery simulators.

The Strategic Location and Comprehensive Services of UNTH
Geographically, UNTH is ideally positioned at Ituku/Ozalla, about 21 kilometers southwest of Enugu city center, accessible via the Enugu-Port Harcourt Expressway (A3 highway). This location facilitates quick emergency responses, with proximity to Enugu’s Akanu Ibiam International Airport (just 30 minutes away) for medical evacuations. The 500+ acre campus includes dedicated zones for administration, patient wards, research labs, and recreational facilities, creating a self-contained ecosystem.
UNTH’s services are vast:
- Clinical Departments: From cardiology (handling Nigeria’s rising heart disease burden) to neurosurgery, with specialized units for burns and plastic surgery.
- Diagnostic Excellence: Advanced labs for histopathology, microbiology, and radiology, equipped with CT scans and ultrasound machines.
- Educational Offerings: The School of Medical Laboratory Sciences and Post-Basic Nursing programs train allied health professionals.
- Research Focus: Partnerships with institutions like the Nigerian Institute of Medical Research yield breakthroughs in malaria and HIV management.
- Community Impact: Mobile clinics reach underserved areas in Enugu North and South Senatorial Districts, offering free screenings for hypertension and diabetes.
“UNTH’s location in Enugu’s serene yet accessible terrain allows interns to focus on learning without urban distractions,” notes Dr. Ifeoma Nwankwo, a UNTH consultant and mentor.
Historical Evolution of the UNTH Internship Program
Tracing back to the 1970s, UNTH’s internship began as a basic housemanship, evolving amid Nigeria’s post-civil war reconstruction. By the 1980s, it incorporated CBT elements to standardize assessments, influenced by MDCN reforms. The 2000s saw digitization, with full CBT adoption in 2015 to curb malpractices.
Today, in 2025, the program accommodates 100-150 interns yearly, prioritizing merit over connections. Historical data shows pass rates hovering at 40-60%, underscoring the need for thorough prep. Manny Spark‘s resources draw from this evolution, incorporating trends like increased emphasis on evidence-based medicine.

Demystifying the UNTH Internship Exam Structure
The exam is a 2-hour CBT with 200 MCQs, divided into pre-clinical (anatomy, physiology, biochemistry—40%) and clinical (surgery, medicine, etc.—60%) sections. No negative marking encourages educated guesses. Venues are typically UNTH’s CBT hall or affiliated centers in Enugu.
Post-written, shortlisted candidates face oral interviews assessing communication and ethics.
Core Subjects: A Deep Dive into What’s Tested
Each subject tests foundational and applied knowledge:
- Anatomy: Focuses on systemic structures; expect diagrams mentally.
- Physiology: Homeostasis and pathophysiology.
- Biochemistry: Enzymes, metabolism; Nigeria-relevant like sickle cell.
- Pathology: Disease etiology.
- Surgery: Principles, emergencies.
- Medicine: Internal diagnostics.
- Obstetrics & Gynecology: Maternal health, critical in Nigeria’s high MMR.
- Pediatrics: Child-specific care.
- Pharmacology & Microbiology: Added for holistic prep.
“Integrate subjects— a surgery question might need physiological insight,” advises Dr. Manny.
