A client who has atrial fibrillation is prescribed warfarin therapy.

Which of the following statements by the client indicates an understanding of the medication?

“I should avoid foods that are high in vitamin K.”.

“I should take this medication with food.”.

“I should report any unusual bleeding or bruising to my provider.”.

“I should avoid taking aspirin while taking this medication.”.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

The client's statement, "I should avoid foods that are high in vitamin K," indicates an understanding of the medication. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors. Consistent intake of vitamin K-containing foods helps maintain a stable INR (International Normalized Ratio) and warfarin's effectiveness. Clients on warfarin should be educated about avoiding drastic changes in their vitamin K intake.

Choice B rationale:

Taking warfarin with food or on an empty stomach doesn't significantly impact its efficacy. Therefore, this statement is not indicative of the client's understanding of the medication.

Choice C rationale:

The statement "I should report any unusual bleeding or bruising to my provider" is important but doesn't specifically reflect an understanding of warfarin. It's a general caution for anyone taking anticoagulants.

Choice D rationale:

While it's important to avoid excessive use of medications like aspirin that can increase the risk of bleeding, this statement doesn't directly demonstrate an understanding of warfarin itself.

Correct Answer is B

Explanation

Choice A rationale:

Reporting the 24-hour intake at the current infusion rate is not the most important finding to report to the healthcare provider in this case. It is essential to monitor intake and output, but a single report of the 24-hour intake is not as critical as other findings.

Choice B rationale:

Reporting a serum potassium level of 3.1 mEq/L (3.1 mmol/L) is the most important finding to report to the healthcare provider. The patient's potassium level is below the normal range, indicating hypokalemia. Hypokalemia can have serious cardiac and neuromuscular effects, including arrhythmias and muscle weakness. Prompt intervention, such as potassium supplementation or adjustment of IV fluids, is necessary to address this potentially life-threatening condition.

Choice C rationale:

Reporting a gastric output of 900 mL in the last 24 hours is significant and should be reported to the healthcare provider, but it is not as urgent as the low potassium level. Gastric output should be monitored to assess for signs of improvement or worsening, but hypokalemia takes precedence due to its immediate health risks.

Choice D rationale:

Reporting an increased blood urea nitrogen (BUN) is important for the overall assessment of the patient's renal function but is not the most critical finding in this scenario. The low potassium level is a more immediate concern and requires immediate attention.

A. "Are you planning to obey the voices?" B. "Have you taken any hallucinogens?" C. "When did these voices begin?" D. "Do you believe the voices are real?" E. None F. None

Correct Answer is A

Explanation

Choice A rationale: Safety is the priority when a client experiences auditory hallucinations. The nurse must determine if the voices are "command hallucinations" that might instruct the client to harm themselves or others.

Choice B rationale: While substance use can cause psychosis, this is a secondary assessment. Identifying immediate risk for violence or self-harm takes precedence over determining the specific chemical etiology of the behavior.

Choice C rationale: Establishing the onset of symptoms helps with chronic versus acute diagnosis, but it does not address the immediate safety risk posed by potentially dangerous instructions from the voices.

Choice D rationale: Assessing the client's insight into their condition is important for long-term treatment planning, but it is less critical than identifying the content and intent of the hallucinations.
