Question 1Foundations of Oriental Medicine

According to Yin-Yang theory, which of the following qualities is classified as Yang?

  1. Deficiency
  2. Brightness Correct answer.
  3. Cold
  4. Stillness

Explanation

Yin and Yang sort all phenomena by paired qualities: Yang is bright, warm, active, rising and moving, whereas Yin is dark, cold, still, descending and substantial. Brightness therefore belongs to the Yang category. Cold and stillness are classical Yin qualities, and deficiency describes a state of insufficiency rather than a Yang quality.

Question 2Foundations of Oriental Medicine

In the Sheng (generating) cycle of the Five Elements, which element is generated by Metal?

  1. Water Correct answer.
  2. Earth
  3. Fire
  4. Wood

Explanation

The generating cycle runs Wood produces Fire, Fire produces Earth, Earth produces Metal, Metal produces Water, and Water produces Wood. Metal therefore generates Water, which is why Metal is called the mother of Water.

Question 3Foundations of Oriental Medicine

Which zang organ stores the Essence (Jing) and is regarded as the root of birth, growth and reproduction?

  1. Kidney Correct answer.
  2. Liver
  3. Spleen
  4. Heart

Explanation

The Kidney stores Jing, governs birth, growth, development and reproduction, and is considered the root of the body's Yin and Yang. Liver stores Blood, the Heart houses the Shen, and the Spleen governs transformation and transport.

Question 4Foundations of Oriental Medicine

Which form of Qi is inherited from the parents, stored in the Kidney, and functions as the most fundamental Qi of the body?

  1. Yuan Qi Correct answer.
  2. Wei Qi
  3. Ying Qi
  4. Zong Qi

Explanation

Yuan Qi (Original Qi) derives from congenital Essence stored in the Kidney and is supplemented by acquired Qi; it is the primary motive force behind all physiological activity. Zong Qi, Ying Qi and Wei Qi are all derived or distributed secondarily and have more specific functions.

Question 5Foundations of Oriental Medicine

Which meridian forms the interior-exterior (biao-li) pair with the Lung meridian?

  1. Heart
  2. Spleen
  3. Stomach
  4. Large Intestine Correct answer.

Explanation

Each yin meridian is paired with a yang meridian in an interior-exterior relationship. The Lung (Taiyin) is paired with the Large Intestine (Yangming), a pairing used clinically to treat both the Lung and the Large Intestine together.

Question 6Foundations of Oriental Medicine

Which pathogenic factor is characterized by a sudden onset and symptoms that migrate and change rapidly?

  1. Wind Correct answer.
  2. Cold
  3. Dryness
  4. Dampness

Explanation

Wind is a yang pathogen marked by rapid onset, movement, migration of symptoms and changeability; it tends to attack the upper body and the surface. Cold contracts and congeals, Dampness is heavy and sticky, and Dryness consumes fluids.

Question 7Foundations of Oriental Medicine

A patient presents with high fever, severe thirst, profuse sweating, a red tongue and a rapid, full pulse. In Eight Principle terms this picture represents:

  1. Heat syndrome Correct answer.
  2. Yin syndrome
  3. Cold syndrome
  4. Deficiency syndrome

Explanation

The Eight Principles classify patterns according to interior or exterior, cold or heat, and deficiency or excess. Fever, thirst, sweating, a red tongue and a rapid full pulse are classic signs of the heat category, and the fullness of the pulse points to excess.

Question 8Foundations of Oriental Medicine

Which fluid is thin, clear and watery, circulates with Wei Qi at the surface, and is associated with Yang?

  1. Ye
  2. Xue
  3. Jing
  4. Jin Correct answer.

Explanation

Body fluids are divided into Jin, which is thin, clear and watery and moves with Wei Qi in the exterior, and Ye, which is thick, dense and Yin and moistens the joints, brain and marrow. Jin and Ye together are the body fluids.

Question 9Foundations of Oriental Medicine

A patient reports a chronic low-grade fever, night sweats, heat in the five palms and a red tongue with scanty coating. This presentation is best described as:

  1. Yang deficiency
  2. Yin deficiency with empty heat Correct answer.
  3. Qi stagnation
  4. Excess heat

Explanation

Chronic low-grade fever, night sweats, five-palm heat and a red tongue with little coating are signs of depleted Yin failing to restrain Yang, producing empty heat. The chronic course and lack of a full pulse distinguish deficiency heat from an excess heat pattern.

Question 10Foundations of Oriental Medicine

A patient with Liver Qi stagnation develops irritability and later palpitations and insomnia. Using Five Element theory, this progression is best explained as:

  1. Earth insulting Wood
  2. Fire overacting on Metal
  3. Water failing to nourish Wood
  4. Wood failing to generate Fire Correct answer.

Explanation

In the generating cycle Wood is the mother of Fire, so Liver pathology can affect the Heart, its child element organ. When Liver fails to nourish the Heart, symptoms such as palpitations and insomnia appear alongside the original Liver signs.

Question 11Foundations of Oriental Medicine

Which organ governs the free flow of Qi, stores Blood, and regulates the volume of circulating Blood?

  1. Spleen
  2. Lung
  3. Liver Correct answer.
  4. Heart

Explanation

The Liver is responsible for the smooth, unobstructed movement of Qi throughout the body and stores the Blood, adjusting its volume according to the body's needs. The Heart circulates Blood, the Lung moves Qi and the Spleen holds Blood within the vessels.

Question 12Foundations of Oriental Medicine

Which function is classically attributed to the San Jiao in the theory of the six fu organs?

  1. Housing the Shen and mind
  2. Regulating the water passages Correct answer.
  3. Storing the Essence and bile
  4. Governing the Blood and vessels

Explanation

The San Jiao is described as the official in charge of irrigation, providing the pathway for Qi and water throughout the upper, middle and lower jiao. It is not a solid organ but a functional system connecting the body's water metabolism.

Question 13Foundations of Oriental Medicine

Which clinical feature is most characteristic of Dampness as a pathogenic factor?

  1. Sudden chills and shivering
  2. Dry cough with scant sputum
  3. High fever with profuse sweating
  4. Heaviness and greasy coating Correct answer.

Explanation

Dampness is a heavy, turbid, sticky and lingering yin pathogen, so it produces sensations of heaviness, turbid discharges and a greasy tongue coating. Its sticky nature also explains why damp patterns resolve slowly.

Question 14Foundations of Oriental Medicine

Which emotion is said to injure the Spleen most directly?

  1. Fear
  2. Worry Correct answer.
  3. Grief
  4. Anger

Explanation

In Five Element correspondence, pensiveness and worry knot the Qi and most directly injure the Spleen, impairing transformation and transport. Anger injures the Liver, grief injures the Lung and fear injures the Kidney.

Question 15Foundations of Oriental Medicine

Which Qi circulates outside the vessels, protects the body surface, and controls the opening and closing of the pores?

  1. Yuan Qi
  2. Wei Qi Correct answer.
  3. Zong Qi
  4. Ying Qi

Explanation

Wei Qi is a yang, defensive Qi that moves outside the vessels between the skin and muscles, warming the surface, controlling pore opening and defending against exterior pathogens. Ying Qi, by contrast, moves inside the vessels to nourish.

Question 16Foundations of Oriental Medicine

A patient has aversion to cold, cold limbs, absence of thirst, clear abundant urine and a pale, swollen tongue. These findings indicate:

  1. Interior cold Correct answer.
  2. Exterior heat
  3. Yin deficiency
  4. Interior heat

Explanation

Aversion to cold, cold limbs, no thirst, clear abundant urine and a pale swollen tongue reflect cold located in the interior, typically from deficient Yang failing to warm the body. The absence of fever and thirst excludes heat patterns.

Question 17Foundations of Oriental Medicine

According to zang-fu theory, the Heart governs:

  1. Blood and vessels Correct answer.
  2. Bones and marrow
  3. Tendons and joints
  4. Qi and respiration

Explanation

The Heart is said to govern the Blood and to govern the vessels, driving circulation and giving the pulse its strength, while also housing the Shen. This is why Heart patterns commonly show pulse and complexion changes along with emotional signs.

Question 18Foundations of Oriental Medicine

What is the primary clinical function of the Luo-connecting points?

  1. Expel Wind from the surface
  2. Drain excess from the organ
  3. Tonify the Yuan Qi
  4. Join paired meridians Correct answer.

Explanation

Each Luo point lies on a primary meridian and connects it to its interior-exterior paired meridian, allowing treatment of both the channel and its paired organ. Luo points are also used for conditions of the Luo vessels, including emotional and chronic patterns.

Question 19Foundations of Oriental Medicine

Which zang organ corresponds to the Earth element and opens into the mouth?

  1. Stomach
  2. Lung
  3. Kidney
  4. Spleen Correct answer.

Explanation

The Spleen belongs to the Earth element, opens into the mouth, manifests in the lips and governs transformation and transportation of food and drink. The Stomach is its paired fu organ but is not a zang organ.

Question 20Foundations of Oriental Medicine

The formation of Gu Qi (food Qi) depends primarily on the function of which organs?

  1. Spleen and Stomach Correct answer.
  2. Kidney and Bladder
  3. Heart and Lung
  4. Liver and Gallbladder

Explanation

The Stomach receives and ripens food and drink, and the Spleen transforms and transports the resulting refined essence, producing Gu Qi. This acquired Qi is the basis for producing Zong Qi, Ying Qi and Wei Qi.

Question 21Foundations of Oriental Medicine

Which statement best expresses the classical principle that Yin and Yang are mutually rooted?

  1. The two principles remain static and separate
  2. Yin and Yang never transform into each other
  3. Each serves as the other's material root Correct answer.
  4. Yang is primary and Yin is only secondary

Explanation

Mutual rooting means Yin and Yang depend on each other as the material basis for their existence, so neither can exist alone. This underlies clinical reasoning such as treating Yang deficiency by also supporting Yin, and vice versa.

Question 22Foundations of Oriental Medicine

A patient with Spleen deficiency develops marked epigastric distension, irritability and a wiry pulse in the Liver position. In Five Element terms this pattern is best described as:

  1. Earth insulting Wood
  2. Wood overacting on Earth Correct answer.
  3. Wood generating Fire
  4. Metal subduing Wood

Explanation

When Wood is excessive or Earth is deficient, Wood overacts on Earth in the Ke (controlling) cycle, producing Liver signs such as a wiry pulse and irritability together with Spleen signs such as distension. The reverse situation, a deficient Earth failing to control Water, is the insulting cycle.

Question 23Foundations of Oriental Medicine

The Ming Men (Life Gate) fire is said to reside between the kidneys, and its chief function is to:

  1. Govern the descent of Lung Qi
  2. Store bile and assist digestion
  3. Store the Blood and regulate menstruation
  4. Warm all organs as the root of Yang Correct answer.

Explanation

Ming Men fire is the source of the body's Yang and provides warming and motive force to every organ, including the Spleen and the Lungs. When it declines, cold and deficient Yang signs appear throughout the body.

Question 24Foundations of Oriental Medicine

A Wind-Cold invasion is followed several days later by high fever, sore throat and yellow sputum. In TCM theory this sequence best illustrates that:

  1. A pathogen can transform after entry Correct answer.
  2. Excess pathogens at once become deficiency
  3. Pathogens always remain unchanged once inside
  4. Disease arises only from internal emotions

Explanation

Pathogenic factors do not remain fixed; they may transform according to the body's constitution, the strength of the pathogen and environmental conditions. A Wind-Cold attack penetrating the interior commonly transforms into Heat, producing fever, sore throat and yellow sputum.

Question 25Foundations of Oriental Medicine

A patient with massive hemorrhage develops a weak pulse, shortness of breath and profuse sweating. This sequence best illustrates which relationship between Qi and Blood?

  1. Qi stagnation leading to Blood stasis
  2. Spleen Qi failing to hold the Blood
  3. Heat in the Blood causing hemorrhage
  4. Qi escaping with the lost Blood Correct answer.

Explanation

Blood is said to be the mother of Qi, so when Blood is lost suddenly, Qi loses its foundation and escapes with it, producing Qi deficiency signs such as a weak pulse and shortness of breath. This is why severe hemorrhage is treated by urgently stabilizing both Qi and Blood.

Question 26Foundations of Oriental Medicine

Extreme heat that suddenly turns into cold is the classic illustration of which Yin-Yang relationship?

  1. Interdependence
  2. Transformation Correct answer.
  3. Consumption
  4. Opposition

Explanation

Transformation describes a qualitative change in which one aspect becomes its opposite when conditions reach an extreme. Extreme heat turning into cold is the standard example of this principle.

Question 27Foundations of Oriental Medicine

In the Five Element controlling (Ke) cycle, which element controls Water?

  1. Wood
  2. Metal
  3. Fire
  4. Earth Correct answer.

Explanation

The Ke cycle runs Wood to Earth, Earth to Water, Water to Fire, Fire to Metal, and Metal to Wood. Therefore Earth controls Water.

Question 28Foundations of Oriental Medicine

Which zang organ is called the delicate organ because it is easily invaded by Wind-Cold and other external pathogens?

  1. Kidney
  2. Liver
  3. Lung Correct answer.
  4. Spleen

Explanation

The Lung is the uppermost zang, opens to the nose, and communicates directly with the exterior, so external pathogens often attack it first. This is why it is termed the delicate organ.

Question 29Foundations of Oriental Medicine

Which organ grasps Qi and serves as the root of Qi, particularly in respiration?

  1. Kidney Correct answer.
  2. Lung
  3. Liver
  4. Spleen

Explanation

The Kidney grasps and anchors the Qi that the Lung inhales, making it the root of Qi. The Lung governs Qi, but the Kidney is responsible for its reception and stabilization.

Question 30Foundations of Oriental Medicine

Which organ function keeps Blood within the vessels and prevents hemorrhage?

  1. The Liver's storage of Blood
  2. The Spleen's holding of Blood Correct answer.
  3. The Heart's governing of Blood
  4. The Lung's dispersing of Qi

Explanation

The Spleen holds Blood in the vessels; when Spleen Qi is deficient, blood may leak out and cause bruising or bleeding. The Heart and Liver have other roles in circulating and storing Blood.

Question 31Foundations of Oriental Medicine

Which fu organ is known as the sea of water and grain because it receives and ripens food?

  1. Small Intestine
  2. Stomach Correct answer.
  3. Bladder
  4. Gallbladder

Explanation

The Stomach receives food and drink and ripens it, preparing it for the Spleen to transform; hence it is called the sea of water and grain. It also governs the downward movement of Qi.

Question 32Foundations of Oriental Medicine

In Five Element correspondences, the sour taste is associated with which element?

  1. Fire
  2. Earth
  3. Metal
  4. Wood Correct answer.

Explanation

Each element has a characteristic flavor: Wood corresponds to sour, Fire to bitter, Earth to sweet, Metal to pungent, and Water to salty. Sour therefore belongs to Wood.

Question 33Foundations of Oriental Medicine

Which of the following organs is classified as a Yang fu organ?

  1. Liver
  2. Heart
  3. Kidney
  4. Gallbladder Correct answer.

Explanation

The zang organs are Yin and the fu organs are Yang. The Gallbladder is a fu organ, whereas the Heart, Liver, and Kidney are zang organs.

The Du Mai travels up the posterior midline and is known as the sea of Yang meridians. The Ren Mai runs on the anterior midline and is the sea of Yin meridians.

Question 38Foundations of Oriental Medicine

Which pathogenic factor occurs in summer, consumes Qi and Yin, and is frequently combined with Dampness?

  1. Wind
  2. Cold
  3. Dryness
  4. Summerheat Correct answer.

Explanation

Summerheat is a Yang pathogen that arises in hot summer weather, causes profuse sweating, and consumes both Qi and Yin. It commonly combines with Dampness, producing summerheat-damp.

Question 39Foundations of Oriental Medicine

A patient presents with severe dizziness, tremors of the limbs, and sudden deviation of the mouth and eye. Which pattern is most likely?

  1. Spleen Dampness
  2. Liver Qi stagnation
  3. Heart Fire
  4. Liver Wind Correct answer.

Explanation

Liver Wind is characterized by abnormal movement such as tremors, dizziness, convulsions, or sudden deviation of the mouth. It often arises from Liver Yang rising or Liver Blood and Yin deficiency.

Question 40Foundations of Oriental Medicine

A patient has acute severe pain that is worse with pressure, a loud voice, and a strong, full pulse. This presentation is classified as which pattern?

  1. Deficiency
  2. Yang Deficiency
  3. Empty Heat
  4. Excess Correct answer.

Question 41Foundations of Oriental Medicine

The coordination of water and fire, in which Kidney water ascends to cool the Heart and Heart fire descends to warm the Kidneys, describes the relationship between which two organs?

  1. Heart and Kidney Correct answer.
  2. Lung and Kidney
  3. Spleen and Heart
  4. Liver and Heart

Explanation

The Heart-Kidney axis is the classic water-fire relationship: Heart Yang descends to warm Kidney Yang, and Kidney Yin ascends to moisten Heart Yin. This keeps the upper body from becoming too hot and the lower body from becoming too cold.

Question 42Foundations of Oriental Medicine

Which fu organ is the interior-exterior pair of the Lung?

  1. Stomach
  2. Gallbladder
  3. Large Intestine Correct answer.
  4. Small Intestine

Explanation

The Lung and Large Intestine form a Yin-Yang interior-exterior pair through the hand Tai Yin and hand Yang Ming channels. The Lung's descending function also supports Large Intestine movement.

Question 43Foundations of Oriental Medicine

Which presentation is most characteristic of Qi stagnation?

  1. Fixed stabbing pain that is worse at night
  2. Chronic dull ache with cold limbs
  3. Sudden high fever with severe thirst
  4. Distending, migrating pain relieved by belching Correct answer.

Explanation

Qi stagnation produces distension, pain that moves, and symptoms relieved by belching or emotional release. Fixed stabbing pain indicates Blood stasis instead.

Question 44Foundations of Oriental Medicine

Fixed, stabbing pain that is worse at night, a purple tongue, and petechiae indicate which pattern?

  1. Blood deficiency
  2. Dampness
  3. Blood stasis Correct answer.
  4. Qi stagnation

Explanation

Blood stasis is marked by fixed, stabbing pain, a purple or dark tongue, petechiae, and pain that worsens at night. Qi stagnation, by contrast, causes moving distending pain.

Question 45Foundations of Oriental Medicine

A sensation of a lump in the throat that cannot be swallowed or coughed up is most characteristic of which pathogenic factor?

  1. Dryness
  2. Cold
  3. Wind
  4. Phlegm Correct answer.

  1. Yin Deficiency with Empty Heat
  2. Yang Deficiency with Cold
  3. True Heat with False Cold Correct answer.
  4. True Cold with False Heat

Explanation

In true Heat with false Cold, internal Heat blocks Yang from reaching the limbs, so the limbs feel cold while the core signs remain hot. The red face, thirst, and full rapid pulse confirm the underlying Heat.

Question 47Foundations of Oriental Medicine

Which extraordinary vessel encircles the waist and binds the vertical meridians, helping to keep Yin and Yang in balance?

  1. Chong Mai
  2. Du Mai
  3. Dai Mai Correct answer.
  4. Ren Mai

Explanation

The Dai Mai is the girdle vessel; it encircles the waist and binds the vertical channels, helping to stabilize the relationship between the upper and lower body. Its dysfunction often produces a feeling of fullness or weakness at the waist.

Question 48Foundations of Oriental Medicine

What is the primary role of the Pericardium in zang-fu theory?

  1. It stores bile and governs decision-making
  2. It separates clear from turbid
  3. It protects the Heart from external Heat and pathogens Correct answer.
  4. It regulates the water passages

Explanation
