Hypothyroidism can cause which of the following symptoms?

Correct Answer: D

Rationale: The correct answer is D because hypothyroidism, a condition where the thyroid gland doesn't produce enough hormones, can lead to brittle hair and nails due to decreased metabolic activity affecting hair and nail growth. Increased hair growth (A) is associated with hyperthyroidism, not hypothyroidism. Weight loss (B) is a symptom of hyperthyroidism where metabolism is increased. Nausea or diarrhea (C) are not typical symptoms of hypothyroidism which usually presents with weight gain and constipation.

Correct Answer: C

Rationale: The correct answer is C: Autopsy. An autopsy is a thorough examination of a body by a pathologist to determine the cause of death. Atrophy (A) refers to the wasting away of body tissues, not an examination. Anatomy (B) is the study of the structure of organisms, not specifically related to determining cause of death. Avulsion (D) is the tearing away of a body part, not related to postmortem examinations. Therefore, C is the correct answer as it directly relates to the process of determining cause of death through a detailed examination.

Correct Answer: C

Rationale: The correct answer is C: Hepatitis B. This is because Hepatitis B is an occupational hazard for healthcare workers, requiring employers to provide the vaccine to employees free of charge. Measles, Ebola, and Malaria are not typically considered occupational hazards in most work settings, so providing vaccines for these diseases is not a legal requirement for employers. Hepatitis B vaccination helps protect employees from potential exposure in the workplace, making it a necessary and mandated vaccine for certain occupations.
