1. 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 may not effectively filter excess potassium from the blood, leading to hyperkalemia. Calcium, iron, and zinc do not need to be avoided specifically in chronic renal failure unless there are other underlying reasons or complications.

2. A healthcare provider is caring for a client who takes an antidepressant and oral contraceptives. Which herbal supplement should the healthcare provider educate the client about due to a drug-herb interaction?

• A. Iron supplement
• B. Garlic
• C. Green tea
• D. St. John’s Wort

Correct answer: D

Rationale: The correct answer is D, St. John’s Wort. St. John’s Wort can interact with antidepressants and oral contraceptives, potentially reducing their efficacy. Iron supplement, garlic, and green tea are not typically known to have significant interactions with antidepressants or oral contraceptives, making them less likely to impact the client's treatment.

3. Which nutrient deficiency is most likely to be seen in patients with chronic alcoholism?

• A. Vitamin C
• B. Vitamin D
• C. Vitamin B12
• D. Vitamin B1

Correct answer: D

Rationale: In patients with chronic alcoholism, the most likely nutrient deficiency is Vitamin B1 (thiamine), not Vitamin B12. Chronic alcoholism often leads to Vitamin B1 deficiency, causing conditions like Wernicke's encephalopathy. While other vitamin deficiencies can also occur in chronic alcoholism, such as Vitamin C and Vitamin D, Vitamin B1 deficiency is more commonly associated with alcoholism.

4. People who use monoamine oxidase inhibitors for the treatment of depression need to avoid foods high in:

• A. Folate
• B. Tyramine
• C. Potassium
• D. Vitamin K

Correct answer: B

Rationale: The correct answer is B: Tyramine. Tyramine can interact with monoamine oxidase inhibitors, leading to hypertensive crises. Folate (choice A) is not contraindicated with monoamine oxidase inhibitors. Potassium (choice C) is an essential mineral and not specifically contraindicated with these medications. Vitamin K (choice D) is not a concern for interactions with monoamine oxidase inhibitors.

5. 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.
