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 hemoglobin, which carries oxygen in red blood cells. Anemia is often due to an iron deficiency, so increasing iron intake helps replenish iron stores and improve red blood cell production. Reducing vitamin intake (A) is not recommended as vitamins play a crucial role in overall health. Injections of vitamin K (C) are not typically used to treat anemia. Decreasing fiber in the diet (D) is unrelated to anemia and can even worsen the condition by limiting nutrient absorption.

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.

Correct Answer: C

Rationale: The correct answer is C: Never. Leaving something blank on a job application is generally not recommended as it may give the impression of being unprepared or careless. Providing as much information as possible is crucial in showcasing professionalism and attention to detail. It is better to acknowledge any gaps in information and offer explanations or alternative contact details if necessary. Therefore, the best practice is to always complete all sections of a job application to the best of one's ability. Choices A, B, and D are incorrect because applicants should make an effort to provide all relevant information or at least acknowledge any missing details.
