A nurse in a clinic is caring for a client who has recently begun taking warfarin. The nurse is reviewing potential drug and food interaction risks and should instruct the client to avoid which of the following?
Cabbage
Green beans
White beans
Cantaloupe
The Correct Answer is A
A. Cabbage: This is the correct answer. Cabbage is a food high in vitamin K, which can antagonize the effects of warfarin. Warfarin is an anticoagulant that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-rich foods, such as cabbage, can affect the stability of the client's international normalized ratio (INR).
B. Green beans: Green beans are not particularly high in vitamin K, and their consumption is not usually restricted for clients taking warfarin.
C. White beans: White beans are not particularly high in vitamin K, and their consumption is not usually restricted for clients taking warfarin.
D. Cantaloupe: Cantaloupe is not high in vitamin K, and its consumption is not usually restricted for clients taking warfarin.

Correct Answer is D
Explanation
A. Call emergency services for the client: While difficulty breathing is a concerning symptom, the immediate priority is to assess the client's respiratory status to determine the cause and appropriate interventions. Calling emergency services may be necessary based on the assessment findings, but assessment comes first.
B. Increase the oxygen flow to 3 L/min: Adjusting oxygen flow may be part of the intervention, but it should be based on a comprehensive assessment of the client's respiratory status. Simply increasing the oxygen flow without a thorough assessment may not address the underlying issue.
C. Have the client cough and expectorate secretions: This action may be appropriate if the client is experiencing difficulty breathing due to increased bronchial secretions. However, assessment is needed to determine the cause of the difficulty breathing before implementing interventions.
D. Assess the client's respiratory status: This is the correct answer. Assessment is the priority when a client with COPD on oxygen reports difficulty breathing. The nurse should gather information about the client's respiratory rate, effort, oxygen saturation, lung sounds, and overall respiratory distress to determine the appropriate course of action.
Correct Answer is A
Explanation
A. Fatigue: Hypokalemia (low potassium levels) can lead to fatigue and weakness. Potassium is essential for proper muscle and nerve function, and a deficiency can result in muscle weakness and decreased energy levels.
B. Pitting edema: Pitting edema is more commonly associated with fluid retention, which can occur in heart failure. Hypokalemia is not typically a direct cause of pitting edema.
C. Dyspnea: Dyspnea (shortness of breath) is a symptom commonly associated with heart failure, and while potassium imbalance can affect cardiac function, it is not a specific manifestation of hypokalemia.
D. Oliguria: Oliguria (decreased urine output) is not a typical manifestation of hypokalemia. However, it can be associated with heart failure and other renal conditions.
