A chronic inflammatory disease of the large intestine or colon is called

Correct Answer: D

Rationale: The correct answer is D: Ulcerative colitis. This chronic inflammatory disease specifically affects the large intestine or colon, causing ulcers and inflammation in the colon's lining. Malabsorption (A) is a condition where the small intestine cannot absorb nutrients properly. Fecal impaction (B) is a severe constipation issue, not related to chronic inflammation. Crohn's disease (C) is a separate inflammatory bowel disease that can affect any part of the digestive tract, not just the colon. Ulcerative colitis is the only choice that accurately describes a chronic inflammatory disease specific to the large intestine.

Correct Answer: C

Rationale: The correct answer is C: Pernicious anemia. Pernicious anemia is caused by the body's inability to absorb vitamin B12, leading to a deficiency in this essential nutrient. Vitamin B12 is crucial for the production of red blood cells, and its deficiency can result in anemia. Pulmonary edema (A) is excess fluid in the lungs, congestive heart failure (B) is a heart condition, and phlebitis (D) is inflammation of a vein, none of which are directly related to vitamin B12 absorption.

Correct Answer: B

Rationale: The correct answer is B: Yellow or green sputum. Acute bronchitis is characterized by inflammation of the bronchial tubes, leading to increased mucus production. The sputum can appear yellow or green due to the presence of white blood cells, indicating an infection. Coughing up blood (choice A) is more commonly associated with conditions like pneumonia or lung cancer. Night sweats (choice C) are typically seen in conditions like tuberculosis or lymphoma. Excessive urination (choice D) is not a common symptom of acute bronchitis.

Correct Answer: B

Rationale: The correct answer is B: Use room fresheners. Substance abusers may use room fresheners to mask the smell of drugs or alcohol. This can help them hide their addiction from others by creating a more pleasant environment. Avoiding brushing their teeth (A) would not effectively hide their addiction, making eye contact (C) is unrelated to hiding addiction, and having strong social relationships (D) may not necessarily conceal their substance abuse. Using room fresheners is a direct method to cover up the scent associated with substance abuse.

Correct Answer: B

Rationale: When the body is exposed to an allergen, the immune system releases histamine. Histamine is a key player in triggering allergic reactions by causing inflammation, itching, and other symptoms. Lymph is involved in the immune response but is not directly released in response to allergens. Hormones and platelets are not the primary substances released in response to allergens.
