Discharge of pus or mucus from the uterus is called as:

Correct Answer: C

Rationale: The correct answer is C: Metrorrhea. Metrorrhea refers to the discharge of pus or mucus from the uterus. Dysmenorrhea (A) is severe menstrual pain, Hypomenorrhea (B) is abnormally light menstrual flow, and Oligomenorrhea (D) is infrequent or light menstrual periods. Therefore, based on the definition provided in the question, Metrorrhea is the correct term for the discharge of pus or mucus from the uterus.

Correct Answer: C

Rationale: The correct answer is C: Amniotic sac. This structure is often referred to as the "bag of water" because it is a fluid-filled sac that surrounds and protects the developing fetus during pregnancy. The amniotic sac provides cushioning and maintains a stable environment for the fetus to grow. It is essential for the baby's development and acts as a barrier against infections. Choice A: Urinary bladder - This structure is responsible for storing urine and is not typically referred to as the bag of water. Choice B: Gall bladder - This organ stores bile produced by the liver and aids in digestion, not related to pregnancy or fetal development. Choice D: Uterus - While the uterus is involved in pregnancy and fetal development, it is not commonly referred to as the bag of water.

Correct Answer: D

Rationale: The correct answer is D: Osteomyelitis. Osteomyelitis refers to inflammation of bone and bone marrow secondary to infection. "Osteitis" (choice A) is a general term for bone inflammation without specifying infection. "Osteochondritis" (choice B) is inflammation of bone and cartilage, not bone marrow. "Osteom" (choice C) is not a recognized medical term. Therefore, based on the specific definition provided in the question, osteomyelitis is the most appropriate answer.

Correct Answer: B

Rationale: The lower jaw bone is known as the mandible. The mandible is the only movable bone in the skull, forming the lower jaw and holding the lower teeth in place. The maxilla (A) is the upper jaw bone. The temporal bone (C) is a bone that forms part of the skull, but it is not the lower jaw bone. Menton (D) is a landmark on the mandible, not the name of the bone itself. Therefore, the correct answer is B (Mandible) as it is specifically designated as the lower jaw bone.

Correct Answer: B

Rationale: The correct answer is B: Crepitations. Crepitations refer to the crackling sound produced by bones rubbing against each other. Rales (A) are abnormal lung sounds, Crackles (C) are fine crackling sounds heard in the lungs, and Vibration (D) is not a term related to bone sounds. Therefore, B is the correct choice as it specifically describes the bone-related sound mentioned in the question.
