Which of the following vitamins should the nurse include in the teaching?
Thiamin
Vitamin K
Folate
Vitamin A
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. Spironolactone is a potassium-sparing diuretic that can cause hyperkalemia, which can lead to symptoms such as increased thirst. Notifying the provider of increased thirst can help monitor for potential electrolyte imbalances.
B. Consuming foods high in potassium can exacerbate hyperkalemia, which is a potential side effect of spironolactone. Clients prescribed spironolactone are typically advised to avoid potassium-rich foods.
C. Using a salt substitute to season foods can increase sodium intake, which may counteract the effects of spironolactone and increase the risk of fluid retention and hypertension.
D. Taking spironolactone at bedtime is not typically recommended. It is usually taken in the morning to avoid disrupting sleep due to increased urination.
Correct Answer is C
Explanation
A. While setting goals can be beneficial, simply stating this without providing practical advice or support may not address the client's specific needs.
B. Eating small portions of high-calorie foods first may not be an effective weight loss strategy, as it does not address overall caloric intake or food choices.
C. Self-monitoring eating behaviors, such as keeping a food diary or tracking portion sizes, can help individuals become more aware of their eating habits and identify areas for improvement when trying to lose weight.
D. Tasting food while cooking may not necessarily curb appetite and could potentially lead to increased calorie consumption if the individual ends up eating more during meal preparation.
