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 intense itching, which is a hallmark symptom. This itching can lead to skin damage, inflammation, and recurrent flare-ups. Other choices are incorrect because: A: Change in size of a mole is not typically associated with atopic dermatitis. C: Cancer is not a direct complication of atopic dermatitis. D: While atopic dermatitis can predispose individuals to secondary infections like yeast infections, it is not the primary problem associated with atopic dermatitis.

Correct Answer: B

Rationale: The correct answer is B: Parkinson's disease. This neurodegenerative disorder is characterized by rigid muscles, tremors (especially at rest), and the distinctive pill-rolling movement of the fingers. Epilepsy (A) is a neurological disorder with recurrent seizures. Meniere's disease (C) affects the inner ear, causing vertigo and hearing loss. Dementia (D) refers to a decline in cognitive function. Parkinson's disease best fits the symptoms described in the question, making it the correct answer.

Correct Answer: C

Rationale: The correct answer is C: Autoimmune. In an autoimmune disease, the body's immune system mistakenly attacks its own tissues, unable to differentiate between self and non-self antigens. This results in inflammation and tissue damage. Opportunistic diseases occur when the immune system is weakened, not due to a failure in self-recognition. Progressive diseases refer to conditions that worsen over time, not specifically related to self-recognition. Infectious diseases are caused by pathogens, not by the body's immune system attacking itself.

Correct Answer: C

Rationale: Turning downward is also called pronation. This movement involves rotating a body part downward or inward. In anatomical terms, pronation refers to the inward rotation of the forearm or foot. Supination (A) is the opposite movement of pronation, involving outward rotation. Hyperextension (B) is the excessive extension of a joint beyond its normal range of motion. Extension (D) refers to straightening or unbending a joint. Therefore, the correct answer is C, as it specifically describes the action of turning downward.

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 (A) is the stiffening of muscles after death, Livor mortis (C) is the pooling of blood in the dependent parts of the body, and Algae mortis (D) is not a recognized term in forensic science. Thus, the correct term for the cooling of the body after death is Algor mortis.
