Nursing Elites

1. In patients receiving chemotherapy, which nutrient is often supplemented to manage mucositis?

• A. Vitamin E
• B. Vitamin B12
• C. Zinc
• D. Calcium

Correct answer: C

Rationale: Zinc supplementation is often recommended to manage mucositis in patients undergoing chemotherapy. Zinc plays a crucial role in wound healing and immune function, which can help alleviate the symptoms of mucositis. Vitamin E (Choice A) is known for its antioxidant properties but is not typically used to manage mucositis. Vitamin B12 (Choice B) is important for red blood cell production and nerve function but is not directly associated with mucositis management. Calcium (Choice D) is essential for bone health and muscle function but is not a primary nutrient supplemented to manage mucositis.

2. Which potential complication should the nurse assess for in the client with infective endocarditis who has embolization of vegetative lesions from the mitral valve?

• A. Pulmonary embolism
• B. Decreased urine output
• C. Hemoptysis
• D. Deep vein thrombosis

Correct answer: B

Rationale: The correct answer is 'Decreased urine output.' Embolization of vegetative lesions from the mitral valve can cause renal infarction, leading to a decrease in urine output. This complication is due to the obstruction of blood flow to the kidneys. Choices A, C, and D are incorrect because embolization from the mitral valve typically does not directly cause pulmonary embolism, hemoptysis, or deep vein thrombosis.

3. 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.

4. 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.

5. The nurse administers 2 units of salt-poor albumin to a client with portal hypertension and ascites. The nurse explains to the client that this is administered to:

• A. Provide nutrients
• B. Increase protein stores
• C. Elevate the circulating blood volume
• D. Divert blood flow away from the liver temporarily

Correct answer: C

Rationale: The correct answer is C: Elevate the circulating blood volume. Albumin increases the circulating blood volume, which helps to reduce ascites and improve hemodynamics in clients with portal hypertension. Choice A is incorrect because salt-poor albumin is not primarily administered to provide nutrients. Choice B is incorrect because the main purpose of administering albumin is not to increase protein stores but to address fluid shifts. Choice D is incorrect because administering albumin does not divert blood flow away from the liver temporarily; instead, it helps improve blood volume and circulation.
