1. Which vitamin deficiency is most likely to be associated with increased risk of macular degeneration?

A. Vitamin A
B. Vitamin B12
C. Vitamin C
D. Vitamin E

Correct answer: D

Rationale: Vitamin E is an antioxidant that helps protect eye health and prevent macular degeneration.

2. Which meal should be removed for a client taking warfarin?

A. Oriental cabbage salad with chicken
B. Beef enchilada, rice, and beans
C. Ham and cheese sandwich
D. Macaroni salad and grapefruit slices

Correct answer: C

Rationale: The correct meal to remove for a client taking warfarin is the 'Ham and cheese sandwich.' Ham is high in vitamin K, which can interfere with the effectiveness of warfarin, a medication that works by decreasing the clotting ability of the blood. Vitamin K can counteract the effects of warfarin by promoting blood clotting. Choices A, B, and D do not contain high amounts of vitamin K and are therefore safer options for individuals taking warfarin.

3. When can a patient's medical record become a potential issue for the doctor or nurse?

A. When the record is extensive
B. When a medical record is subpoenaed in court
C. When it is missing
D. When the medical record is inaccurate, incomplete, or inadequate

Correct answer: D

Rationale: The correct answer is D. A medical record becomes a potential issue for a doctor or a nurse when it is inaccurate, incomplete, or inadequate. This is because a medical record is a key tool for healthcare professionals to track a patient's history, treatment, and progress. If the record is not accurate or complete, it can lead to misdiagnosis, incorrect treatment, or other potential problems in patient care. While missing records (Choice C) could be a problem, they do not directly implicate the doctor or nurse in the same way that inaccurate or inadequate records do. An extensive record (Choice A) or a record being subpoenaed in court (Choice B) are not inherently problematic for healthcare professionals and do not necessarily reflect negatively on their work.

4. The most energy-rich nutrient is:

A. carb
B. fat
C. protein
D. water

Correct answer: B

Rationale: Fat provides 9 kcal per gram, making it the most energy-rich nutrient compared to carbohydrates and proteins, which provide 4 kcal per gram.

5. Which of the following is a good food source of iodine?

A. Seafood
B. Lettuce
C. Broccoli
D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.
