Which food item interferes with the effectiveness of warfarin?

Correct Answer: D

Rationale: Broccoli is high in vitamin K, which can affect the effectiveness of warfarin. Warfarin is an anticoagulant medication that functions by reducing the activity of vitamin K in the body. When one consumes broccoli, which is rich in vitamin K, it could counteract the anticoagulant effect of warfarin, thereby interfering with its effectiveness. On the other hand, cauliflower, zucchini, and green beans do not have significant levels of vitamin K and hence, are not known to impact the effectiveness of warfarin.

Correct Answer: C

Rationale: Fortified soy milk is a reliable source of vitamin B12 for pregnant vegan clients as it is usually enriched with this vitamin. The other options, while nutritious, are not reliable sources of B12 for vegans. Soybeans may not provide enough B12, algae contains B12 analogs that the human body cannot utilize, and the B12 content in sea vegetables can fluctuate, potentially not providing the necessary daily intake.

Correct Answer: D

Rationale: The correct answer is D: Potential risk of foodborne illness. Patients undergoing chemotherapy have compromised immune systems, making them more susceptible to foodborne illnesses. Chemotherapy can reduce the count of white blood cells, which impairs the body's ability to fight off infections from bacteria or other pathogens that might be present in food. Therefore, the prevention of foodborne illnesses is a critical concern for these patients. Choices A, B, and C, while they represent valid concerns for food safety in general, are not the primary concern for patients undergoing chemotherapy. These patients are at a heightened risk of experiencing severe complications from foodborne illnesses, making it a more significant concern than potential food allergies, food-drug interactions, or pesticide residues.

Correct Answer: B

Rationale: Decreasing the intake of refined carbohydrates is the most effective dietary modification for a client with type 2 diabetes who aims to improve their glycemic control. Refined carbohydrates can cause sudden spikes in blood sugar levels, making diabetes management more difficult. Increasing the intake of saturated fats (Choice A) is not advisable as it can negatively impact heart health. Completely avoiding all fruits (Choice C) is unnecessary because most fruits have a low glycemic index and provide essential nutrients. Increasing the intake of sugary snacks (Choice D) will deteriorate glycemic control due to their high sugar content.

Correct Answer: D

Rationale: The correct answer is 'D: Risk for infection.' An indwelling urinary catheter poses a significant risk for infection due to its invasive nature and the increased susceptibility to urinary tract infections. While 'B: Impaired urinary elimination' and 'C: Impaired skin integrity' may also be concerns for a patient with an indwelling urinary catheter, the immediate risk of infection is the priority. 'A: Self-esteem disturbance' is not typically a priority nursing diagnosis for a patient with an indwelling urinary catheter because the focus is primarily on infection prevention and management to ensure patient safety and well-being.
