The four elements that make up about 96% of the human body are
hydrogen, carbon, potassium, nitrogen
carbon, nitrogen, oxygen, hydrogen
phosphorus, calcium, nitrogen, hydrogen
calcium, helium, oxygen, nitrogen
The Correct Answer is B
A. Hydrogen, carbon, potassium, nitrogen: While hydrogen, carbon, and nitrogen are major elements in the human body, potassium is a trace element and does not contribute significantly to the 96% composition.
B. Carbon, nitrogen, oxygen, hydrogen: These four elements constitute approximately 96% of the human body. They form the building blocks of organic molecules such as proteins, carbohydrates, lipids, and nucleic acids, making them essential for life.
C. Phosphorus, calcium, nitrogen, hydrogen: Phosphorus and calcium are important elements, particularly in bones and energy molecules, but they are present in much smaller amounts compared to carbon, hydrogen, oxygen, and nitrogen.
D. Calcium, helium, oxygen, nitrogen: Helium is not a biological element in the human body, and while calcium, oxygen, and nitrogen are present, this set does not reflect the four major elements that make up 96% of body composition.

Correct Answer is A
Explanation
A. On the posterior side of the knee: The popliteal pulse is located behind the knee in the popliteal fossa. It is often deeper and harder to palpate compared to other pulses, but it is the correct site when assessing circulation in the lower extremity.
B. In the distal end of the lower leg: The distal lower leg is where the posterior tibial and dorsalis pedis pulses are assessed. These are important for evaluating foot circulation but are not the same as the popliteal pulse.
C. At the posterior side of the wrist: The posterior wrist is where the radial pulse is palpated. This site is commonly used for routine pulse checks but is unrelated to the popliteal artery location.
D. On the palmar side of the hand: Pulses in the hand can be felt at sites such as the ulnar artery, but these are not associated with the popliteal region. This location is far from the knee and does not correspond to the popliteal pulse point.
Correct Answer is D
Explanation
A. Fingers: The general term for fingers is “digits” or “phalanges,” not pollex.
B. Calf: The calf corresponds to the sural region, unrelated to the pollex.
C. Great toe: The great toe is called the hallux, not the pollex.
D. Thumb: The term pollex specifically refers to the thumb, which is the first digit of the hand and is opposable, aiding in grasping and manipulation of objects.
