Correct Answer: A

Rationale: The liver is responsible for secreting bile, which aids in the emulsification and digestion of fats. Bile is produced by the liver and is stored and concentrated in the gallbladder before being released into the small intestine to help with the breakdown of fats during the digestion process. The gallbladder functions as a storage organ for bile produced by the liver. The pancreas secretes digestive enzymes and bicarbonate to aid in the digestion process, while the spleen is mainly involved in immune function and blood storage.

Correct Answer: D

Rationale: In this scenario, the patient's presentation of a painless thyroid nodule and hoarseness of voice is consistent with papillary thyroid carcinoma, a type of thyroid cancer. While Hashimoto's thyroiditis and Graves' disease are autoimmune thyroid conditions that can lead to thyroid nodules, they typically do not present with hoarseness of voice. Diabetes mellitus does not directly cause these symptoms. Thyroid cancer, particularly papillary thyroid carcinoma, is the most likely cause based on the patient's clinical presentation and the biopsy results.

Correct Answer: C

Rationale: When a pregnant woman is diagnosed with preeclampsia, the focus of health care shifts to the individual woman herself. Preeclampsia is a serious condition that affects the health of the pregnant woman and her unborn child. The healthcare team will prioritize the care and treatment of the woman to ensure her well-being and safety. In this scenario, the emphasis is on providing personalized and targeted care to address the needs of the individual patient, rather than a broader focus on population groups, communities, or families.

Correct Answer: B

Rationale: Goiter is a condition characterized by the enlargement of the thyroid gland. The most common cause of goiter worldwide is iodine deficiency, which is required for the production of thyroid hormones. When there is insufficient iodine intake, the thyroid gland enlarges in an attempt to produce more hormones, leading to the development of goiter. While other factors can also contribute to the development of goiter, such as autoimmune diseases and certain medications, the primary cause associated with the condition is an iodine-deficient diet.

Correct Answer: C

Rationale: The main source of nutrition for the baby during pregnancy is the placenta. The placenta is an organ that develops inside the uterus during pregnancy and provides essential nutrients and oxygen from the mother's blood to the baby through the umbilical cord. It acts as a barrier, protecting the baby from harmful substances while allowing necessary nutrients to pass through. The amniotic fluid serves as a protective cushion for the baby, the uterus provides the space for the baby to grow, and chorionic villi are small, hair-like structures on the placenta that aid in the exchange of nutrients and waste between the mother and the baby. However, the primary source of nutrition for the baby is the placenta, making option C the correct answer in this scenario.
