Nursing Elites

1. Who typically collects blood specimens?

• A. The nurse
• B. Medical technologist
• C. Physician
• D. Phlebotomist

Correct answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician. Physicians are not commonly involved in the direct collection of blood specimens. While phlebotomists are specialized professionals trained to draw blood, in many medical settings, nurses perform this task as part of their responsibilities.

2. Under the health services support area concept, how is the medical care under the MEDCOM divided?

• A. Six geographical regions of the United States with command authority in each region
• B. Five levels of health service support, each providing different levels of health care services
• C. Primary and secondary health care regions, each containing a MEDDAC or MEDCEN
• D. Eight geographical areas of responsibility designated as health services support regions, each of which is subdivided into two or more health service areas

Correct answer: D

Rationale: The correct answer is D. Under the health services support area concept, the medical care under the MEDCOM is divided into eight geographical areas of responsibility designated as health services support regions, each of which is further subdivided into two or more health service areas. This structure allows for a more organized and efficient delivery of medical care across different regions. Choices A, B, and C are incorrect because they do not accurately describe how medical care under the MEDCOM is divided according to the concept of health services support areas.

3. Which vitamin deficiency is commonly associated with prolonged antibiotic use?

• A. Vitamin A
• B. Vitamin B6
• C. Vitamin C
• D. Vitamin K

Correct answer: D

Rationale: The correct answer is Vitamin K. Prolonged antibiotic use can disrupt the gut flora, which is responsible for synthesizing Vitamin K. This disruption can lead to a Vitamin K deficiency and an increased risk of bleeding. Vitamin A, B6, and C deficiencies are not typically associated with prolonged antibiotic use.

4. Which type of anemia is associated with chronic kidney disease?

• A. Iron-deficiency anemia
• B. Vitamin B12 deficiency anemia
• C. Aplastic anemia
• D. Erythropoietin deficiency anemia

Correct answer: D

Rationale: The correct answer is D, Erythropoietin deficiency anemia. Chronic kidney disease often leads to anemia due to decreased production of erythropoietin. This hormone, produced by the kidneys, stimulates the bone marrow to produce red blood cells. Choices A, B, and C are incorrect. Iron-deficiency anemia is characterized by low iron levels, vitamin B12 deficiency anemia by inadequate vitamin B12, and aplastic anemia by bone marrow failure.

5. Who typically collects blood specimens?

• A. The nurse
• B. Medical technologist
• C. Physician
• D. Pharmacist

Correct answer: A

Rationale: Nurses typically collect blood specimens from patients as part of their everyday duties in medical settings. They are trained in venipuncture techniques and are responsible for ensuring that blood samples are properly obtained and labeled for diagnostic testing. Medical technologists process and analyze the blood specimens in the laboratory under the direction of a physician, but the actual collection of specimens is commonly performed by nurses. Physicians are primarily responsible for diagnosing and treating medical conditions rather than collecting blood specimens. Pharmacists are healthcare professionals who specialize in medication management and dispensing, not in collecting blood specimens.
