A form of cancer that begins in the uterus is called

Correct Answer: D

Rationale: The correct answer is D: Endometrial cancer. The endometrium is the inner lining of the uterus, so cancer that originates there is termed endometrial cancer. Cervical cancer (A) starts in the cervix, not the uterus. Ovarian cancer (B) originates in the ovaries, not the uterus. Testicular cancer (C) affects the testicles, not the uterus. Thus, the correct answer is D as it aligns with the site of origin for uterine cancer.

Correct Answer: B

Rationale: The correct answer is B because padding the edge of the cast helps reduce sharp edges, preventing skin irritation and potential injury. It ensures the patient's comfort and safety. Choice A is incorrect as scratching inside the cast can cause skin damage and infection. Choice C is incorrect as keeping the cast damp or wet can lead to skin breakdown and infection. Choice D is incorrect as keeping the extremity low close to the ground can increase swelling and discomfort.

Correct Answer: C

Rationale: The correct answer is C: Hyperthyroidism. This condition occurs when the thyroid gland produces an excess of thyroid hormone, leading to symptoms such as weight loss, rapid heartbeat, and anxiety. It is crucial to differentiate hyperthyroidism from hypothyroidism (choice A), which is characterized by an underactive thyroid gland resulting in symptoms like fatigue and weight gain. Hypertension (choice B) refers to high blood pressure, unrelated to thyroid hormone production. Hypothermia (choice D) is a condition of abnormally low body temperature, not related to thyroid function. Therefore, hyperthyroidism is the correct answer as it specifically describes the overproduction of thyroid hormone by the thyroid gland.

Correct Answer: B

Rationale: The correct answer is B: Return fluid to the circulatory system. The lymphatic system collects excess fluid from tissues and returns it to the bloodstream to maintain fluid balance. It helps prevent edema and supports immune function by transporting white blood cells. A, C, and D are incorrect because: A: Providing reflex centers for respiration is a function of the nervous system, not the immune or lymphatic systems. C: Protecting internal organs is primarily the function of the skeletal system and organs themselves, not the immune or lymphatic systems. D: Absorbing nutrients is mainly the role of the digestive system, not the immune or lymphatic systems.

Correct Answer: B

Rationale: The correct answer is B, Central venous line. This type of intravenous line is inserted into a large vein in the body, typically in the neck, chest, or groin area. It is used for administering medications, fluids, blood products, and for monitoring central venous pressure. Peripheral line (A) is inserted into a smaller vein in the periphery, not a large vein. Gastrostomy line (C) is used for feeding directly into the stomach. Nasogastric line (D) is inserted through the nose into the stomach for feeding or drainage.
