Nokea
The nurse is aware that norepinephrine is secreted by which endocrine gland?
- A. The pancreas
- B. The adrenal cortex
- C. The adrenal medulla
- D. The anterior pituitary gland
Correct Answer: C
Rationale: Norepinephrine is indeed secreted by the adrenal medulla, making choice C the correct answer. The adrenal medulla is part of the adrenal glands, located on top of the kidneys. Norepinephrine is involved in the body's 'fight or flight' response, helping to prepare the body to react to stress. Choices A, B, and D are incorrect as norepinephrine is not secreted by the pancreas, adrenal cortex, or the anterior pituitary gland.

Which of the following is a nonmedical member of a unit who receives additional training in providing care beyond basic first aid procedures?
- A. Area support squad leader
- B. ATLS specialist
- C. Tactical lifesaver
- D. Combat lifesaver
Correct Answer: D
Rationale: The correct answer is D, 'Combat lifesaver.' A Combat Lifesaver is a nonmedical member of a unit who is trained in advanced first aid procedures, providing care beyond basic first aid. Choice A, 'Area support squad leader,' does not specifically refer to someone trained in providing advanced care. Choice B, 'ATLS specialist,' refers to someone trained in Advanced Trauma Life Support (ATLS), which is beyond the scope of the question. Choice C, 'Tactical lifesaver,' is not a recognized term for the role described in the question.
The client with peripheral venous disease is scheduled to go to the whirlpool for a dressing change. Which is the nurse's priority intervention?
- A. Escort the client to the physical therapy department
- B. Medicate the client 30 minutes before going to the whirlpool
- C. Obtain the sterile dressing supplies for the client
- D. Assist the client to the bathroom prior to the treatment
Correct Answer: B
Rationale: The correct answer is B. Pain management is essential before the procedure to ensure the client's comfort and cooperation during the dressing change. Escorting the client to the physical therapy department (choice A) is not the priority at this time. While obtaining sterile dressing supplies (choice C) is important, ensuring pain management takes precedence. Assisting the client to the bathroom (choice D) is not directly related to the priority intervention of pain management before the whirlpool treatment.
The best position for any procedure that involves vaginal and cervical examination is
- A. Dorsal recumbent
- B. Side lying
- C. Supine
- D. Lithotomy
Correct Answer: D
Rationale: The lithotomy position is the most suitable position for procedures involving vaginal and cervical examination because it provides the best access to the vaginal and cervical regions. In this position, the patient lies on their back with their legs flexed and feet placed in stirrups, allowing for optimal visualization and access to the area. This position facilitates proper examination, diagnosis, and treatment when working in the gynecological field. The other options (dorsal recumbent, side lying, and supine) do not provide the same level of access and visualization as the lithotomy position, making them less ideal for vaginal and cervical examinations.
The nurse is planning to provide education about foods containing thiamine to a group of clients. Which food high in thiamine should the nurse include?
- A. Fish
- B. Pork
- C. Beef
- D. Eggs
Correct Answer: B
Rationale: The correct answer is B: Pork. Pork is high in thiamine, which is important for preventing thiamine deficiency. Thiamine, also known as Vitamin B1, is essential for the body's metabolism and proper functioning of the nervous system. While fish, beef, and eggs are nutritious foods, they do not contain as high levels of thiamine as pork does. Therefore, when educating clients about thiamine-rich foods, pork would be the most appropriate choice.
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 used to manage mucositis in patients receiving chemotherapy. Zinc has been shown to aid in the healing process of mucositis. Vitamin E (Choice A) is not typically used to manage mucositis associated with chemotherapy. Vitamin B12 (Choice B) is essential for nerve function and the formation of red blood cells, but it is not primarily used to manage mucositis. Calcium (Choice D) is important for bone health and nerve function but is not specifically used to manage mucositis.
