A common treatment for anemia is

Correct Answer: B

Rationale: The correct answer is B: Increasing iron intake. Iron is essential for the production of red blood cells, which carry oxygen in the blood. Anemia is often caused by a lack of iron, leading to a decrease in red blood cell production. Increasing iron intake through diet or supplements can help replenish iron stores and improve red blood cell count. Choice A is incorrect because reducing vitamin intake would not address the underlying cause of anemia. Choice C is incorrect as vitamin K is not typically used to treat anemia. Choice D is incorrect as fiber does not directly impact iron absorption or red blood cell production. Overall, increasing iron intake is the most effective treatment for anemia.

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.

Correct Answer: C

Rationale: The correct answer is C: Never. Leaving a blank on a job application is generally not recommended as it may give the impression of being careless or unprepared. Providing as much information as possible is crucial for potential employers to assess your qualifications thoroughly. Leaving blanks can also result in your application being disqualified. Therefore, it is best to strive to complete all sections of a job application to the best of your ability. Choices A, B, and D are incorrect because in each of those scenarios, applicants should make an effort to provide alternative information or explanations instead of leaving the fields blank.
