1. 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.

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, medical care under MEDCOM is divided into eight geographical areas of responsibility. Each of these areas is designated as a health services support region, and they are further subdivided into two or more health service areas. Choices A, B, and C are incorrect because they do not accurately describe how the medical care under MEDCOM is divided.

3. Performing and supervising therapeutic and preventive procedures that have been planned for a patient is part of which of the following steps for determining and fulfilling the nursing care needs of the patient?

• A. Evaluation
• B. Planning
• C. Implementation
• D. Assessment

Correct answer: C

Rationale: The correct answer is C: Implementation. In nursing care, implementation involves carrying out and supervising the planned procedures for the patient. This step focuses on putting the care plan into action. Choice A, Evaluation, involves assessing the effectiveness of the care provided, not performing procedures. Choice B, Planning, is about developing a plan of care, not executing it. Choice D, Assessment, is the initial step in the nursing process where data is collected and analyzed to determine the patient's needs, not the step involving performing and supervising procedures.

4. A patient with chronic renal failure should avoid which of the following?

• A. Potassium
• B. Calcium
• C. Iron
• D. Zinc

Correct answer: A

Rationale: Patients with chronic renal failure should avoid potassium due to impaired kidney function. The kidneys play a crucial role in regulating potassium levels in the body. In renal failure, the kidneys may not be able to excrete excess potassium effectively, leading to hyperkalemia. Calcium, iron, and zinc are not typically restricted in chronic renal failure unless there are specific individual circumstances, making them incorrect choices.

5. 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: The correct answer is C: The adrenal medulla. Norepinephrine is secreted by the adrenal medulla and is involved in the body's 'fight or flight' response. The pancreas (choice A) secretes insulin and glucagon, not norepinephrine. The adrenal cortex (choice B) secretes hormones like cortisol and aldosterone, but not norepinephrine. The anterior pituitary gland (choice D) secretes various hormones like growth hormone and thyroid-stimulating hormone, but not norepinephrine.
