Free MLPAO Anatomy and Medical Terminology Questions and Answers — Questions and Answers
Question 1: A patient lying horizontally on their back with their face pointing upwards is in which anatomical position?
- Prone
- Supine (Correct answer)
- Lateral
- Fowler's
Correct answer: Supine
The supine position is the term for lying horizontally on the back, face up. Prone is the opposite, lying face down. Lateral means lying on the side, and Fowler's is a semi-sitting position.
Question 2: Which anatomical plane divides the body vertically into anterior and posterior (front and back) sections?
- Sagittal Plane
- Transverse Plane
- Coronal Plane (Correct answer)
- Oblique Plane
Correct answer: Coronal Plane
The coronal (or frontal) plane is a vertical plane that divides the body into anterior (front) and posterior (back) portions. The sagittal plane divides the body into left and right sides, and the transverse plane divides it into superior (upper) and inferior (lower) parts.
Question 3: A patient's requisition form notes 'nephritis'. Based on medical terminology, this indicates an inflammation of which organ?
- Liver
- Stomach
- Lungs
- Kidney (Correct answer)
Correct answer: Kidney
The root word 'nephr/o' is derived from the Greek 'nephros', which means kidney. The suffix '-itis' means inflammation. Therefore, nephritis is inflammation of the kidney.
Question 4: Using directional terms, how would the relationship between the elbow and the hand be described?
- The elbow is distal to the hand.
- The elbow is proximal to the hand. (Correct answer)
- The elbow is medial to the hand.
- The elbow is superficial to the hand.
Correct answer: The elbow is proximal to the hand.
Proximal means closer to the point of attachment or the trunk of the body. Since the elbow is closer to the shoulder (the point of attachment) than the hand is, the elbow is proximal to the hand. Distal means farther from the point of attachment.
Question 5: Which of the following organs is part of both the endocrine and digestive systems, playing a dual role in producing hormones like insulin and digestive enzymes?
- Liver
- Adrenal Gland
- Pancreas (Correct answer)
- Thyroid Gland
Correct answer: Pancreas
The pancreas is a heterocrine gland, meaning it has both endocrine (secreting hormones like insulin and glucagon into the blood) and exocrine (secreting digestive enzymes into the small intestine) functions. The liver is primarily digestive, while the adrenal and thyroid glands are purely endocrine.
Question 6: In the context of phlebotomy, the antecubital fossa is a critical anatomical landmark. Which vein within this area is most commonly the first choice for venipuncture due to its size and stability?
- Basilic vein
- Brachial artery
- Cephalic vein
- Median cubital vein (Correct answer)
Correct answer: Median cubital vein
The median cubital vein, located in the antecubital fossa (the crease of the elbow), is the preferred site for venipuncture. It is typically large, well-anchored (less likely to roll), and less painful to access compared to the cephalic and basilic veins. The brachial artery should always be avoided during venipuncture.
