A form of cancer that begins in the uterus is called

Correct Answer: D

Rationale: The correct answer is D: Endometrial cancer. This form of cancer starts in the lining of the uterus, called the endometrium. Cervical cancer (A) originates in the cervix, ovarian cancer (B) in the ovaries, and testicular cancer (C) in the testicles. By process of elimination, endometrial cancer is the only choice that correctly matches the description of cancer beginning in the uterus.

Correct Answer: B

Rationale: The correct answer is B: Pad the edge of the cast to reduce sharp edges. This is important to prevent skin irritation and injury from the rough edges of the cast. By padding the edges, it helps to distribute pressure evenly and decrease the risk of abrasions. Choice A is incorrect because using a sharp scratcher inside the cast can lead to skin damage and infections. Choice C is incorrect as keeping the cast damp or wet can cause skin maceration and increase the risk of infection. Choice D is incorrect as keeping the extremity low close to the ground can lead to swelling and discomfort.

Correct Answer: C

Rationale: The correct answer is C: Hyperthyroidism. Hyperthyroidism is when the thyroid gland produces an excess of thyroid hormone, leading to symptoms like weight loss, rapid heartbeat, and anxiety. Hypothyroidism (A) is the opposite, where the thyroid gland produces too little hormone. Hypertension (B) is high blood pressure and is not directly related to thyroid function. Hypothermia (D) is a condition of abnormally low body temperature and is not caused by thyroid hormone imbalance. In this case, the symptoms described align with hyperthyroidism, making it the correct answer.

Correct Answer: B

Rationale: The correct answer is B: Return fluid to the circulatory system. The lymphatic system helps maintain fluid balance by collecting excess fluid from tissues and returning it to the bloodstream. This process, known as lymphatic drainage, helps prevent swelling and maintains proper circulation. Choices A, C, and D are incorrect as the immune and lymphatic systems do not primarily function to provide reflex centers for respiration, protect internal organs, or absorb nutrients.

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 to provide access for medications, fluids, and blood products. It is used for long-term administration, monitoring of central venous pressure, and rapid fluid resuscitation. A: Peripheral line is inserted into a smaller vein in the extremities. C: Gastrostomy line is used for enteral nutrition and is inserted directly into the stomach. D: Nasogastric line is inserted through the nose into the stomach for gastric decompression or feeding. In summary, the central venous line is the correct choice for accessing a large vein in the body for various medical interventions.
