Thiamin

Folate

Vitamin A

Answer and Explanation

The Correct Answer is B

A.    Thiamin (vitamin B1) is not known to interfere with the anticoagulant effect of warfarin.
B.    Vitamin K is known to counteract the anticoagulant effect of warfarin by promoting the synthesis of clotting factors in the liver. Therefore, clients taking warfarin are advised to
maintain a consistent intake of vitamin K-rich foods to prevent fluctuations in their anticoagulant therapy.

Correct Answer is A

Explanation

A. Eating a larger meal at breakfast and smaller meals throughout the day can help regulate appetite, reduce overall caloric intake, and promote weight loss.
B. Setting a weight loss goal of 2.5 pounds per week may be unrealistic or unsafe for some individuals. A more moderate and sustainable goal, such as 1-2 pounds per week, is typically recommended.
C. Meal replacement shakes can be a convenient option for some individuals as part of a weight loss plan, but they do not inherently cause weight gain. However, it's important to choose meal replacements with appropriate nutritional content and to use them as part of a balanced diet.
D. Drinking water with meals can help promote satiety and may prevent overeating, but it is not the only behavioral modification necessary for successful weight loss.

Correct Answer is D

Explanation

A. TPN typically contains glucose as a source of energy. While it can help maintain glucose levels, this is not the primary reason for its use in clients with acute kidney injury.
B. TPN is not primarily used to address excessive calorie burning. It is used when a client is unable to meet their nutritional needs orally or enterally.
C. While TPN may have varying proportions of macronutrients depending on the individual's nutritional needs, the primary reason for its use in acute kidney injury is to provide nutrition when the gastrointestinal tract cannot be used.

D. TPN bypasses the gastrointestinal tract, delivering nutrients directly into the bloodstream.
This is necessary in acute kidney injury when the client may not be able to tolerate enteral feeding or when there are specific dietary restrictions.
