What is one problem associated with atopic dermatitis (eczema)?

Correct Answer: B

Rationale: The correct answer is B: Itching. Atopic dermatitis is a type of eczema characterized by red, itchy skin. Itching is a common symptom of atopic dermatitis due to skin inflammation and dryness. It can lead to scratching, which further exacerbates the condition. Other choices are incorrect: A is unrelated to atopic dermatitis, C is not a typical complication, and D may occur but is not a primary problem associated with atopic dermatitis.

Correct Answer: B

Rationale: The correct answer is B: Parkinson's disease. This progressive disease is characterized by rigid muscles, tremors, and a pill-rolling motion of the fingers. Parkinson's disease is a neurodegenerative disorder affecting movement control. Epilepsy (A) is a neurological disorder characterized by recurrent seizures. Meniere's disease (C) affects the inner ear, causing vertigo and hearing loss. Dementia (D) is a syndrome involving a decline in cognitive function. Parkinson's disease is the best fit based on the symptoms described.

Correct Answer: C

Rationale: The correct answer is C: Autoimmune. In autoimmune diseases, the body's immune system mistakenly attacks its own tissues, considering them as foreign invaders. This leads to inflammation and damage to the body's own cells and tissues. This is different from opportunistic diseases (A), which take advantage of a weakened immune system, progressive diseases (B) that worsen over time but do not involve immune system dysfunction, and infectious diseases (D) caused by pathogens like bacteria, viruses, or parasites. Therefore, the inability of the body to recognize its own tissue characterizes autoimmune diseases specifically, making C the correct choice.

Correct Answer: C

Rationale: Turning downward is called pronation. This motion involves rotating the forearm so the palm faces downward. Supination is the opposite motion, where the palm faces upward. Hyperextension refers to overextending a joint, not turning downward. Extension is a straightening movement, not specific to turning downward. Therefore, the correct answer is C: Pronation.

Correct Answer: B

Rationale: The correct answer is B: Algor mortis. Algor mortis refers to the cooling of the body after death. This process occurs as the body temperature gradually decreases to match the surrounding environment. Rigor mortis (choice A) is the stiffening of muscles after death, Livor mortis (choice C) is the pooling of blood in the dependent parts of the body, and Algae mortis (choice D) is not a valid term in forensic science. Therefore, B is the correct answer as it specifically relates to the cooling process after death.
