A female patient who follows a vegetarian diet has recently been prescribed warfarin. She mentions that she consumes leafy green vegetables daily.
What should be the nurse’s response?

Praise the patient for her healthy lifestyle and encourage her to maintain her current dietary habits.

Assure the patient that her dietary choices will enhance the effectiveness of the medication in preventing blood clots.

Inform the patient that her healthcare provider needs to be informed about her current diet.

Recommend that the patient substitutes the leafy vegetables with a protein source like nuts or beans.

Answer and Explanation

The Correct Answer is C

Choice A rationale

While maintaining a healthy lifestyle and diet is generally beneficial, consuming large amounts of leafy green vegetables, which are high in vitamin K, can interfere with the effectiveness of warfarin, a medication that works by inhibiting the action of vitamin K-dependent clotting factors. Therefore, praising the patient for her healthy lifestyle without addressing the potential interaction between her diet and medication could lead to suboptimal treatment outcomes.

Choice B rationale

This statement is misleading. While a healthy diet can contribute to overall health and well- being, the patient’s dietary choices, specifically her daily consumption of leafy green

vegetables, could actually decrease the effectiveness of warfarin. Warfarin’s ability to prevent blood clots is dependent on a consistent intake of vitamin K67.

Choice C rationale

This is the most appropriate response. The healthcare provider should be informed about the patient’s current diet because it could impact the effectiveness of warfarin. The provider may need to adjust the dose of warfarin or provide additional dietary guidance to ensure the medication works as intended.

Choice D rationale

While this might seem like a reasonable suggestion, it’s important to remember that dietary changes should be made in consultation with a healthcare provider or a dietitian. Substituting leafy green vegetables with other protein sources may not be necessary or appropriate depending on the patient’s overall diet, nutritional needs, and personal preferences.

Correct Answer is B

Explanation

Choice A rationale

While it’s understandable that the patient’s daughter wants to delay the use of medication until her mother’s symptoms worsen, this approach may not be beneficial. Rivastigmine, a cholinesterase inhibitor, is used to treat mild to moderate dementia caused by Alzheimer’s or Parkinson’s disease. It is not a cure for Alzheimer’s or Parkinson’s disease, but it can help manage the symptoms. Waiting until the symptoms worsen may not provide the desired benefits and could potentially lead to a faster progression of the disease.

Choice B rationale

Rivastigmine is most effective when used early in the disease process. It works by increasing the concentration of acetylcholine, a neurotransmitter, through reversible inhibition of its hydrolysis by cholinesterase. This can help improve the function of nerve cells in the brain and can slow the progression of symptoms in patients with Alzheimer’s disease. Therefore, starting the medication early can help manage the symptoms and potentially slow the progression of the disease.

Choice C rationale

While assessing the patient’s current mental status is an important part of care, it should not be the sole factor in deciding when to start medication. The decision to start medication should be based on a comprehensive evaluation of the patient’s condition, including the stage of the disease, the patient’s overall health, and the potential benefits and risks of the medication.

Choice D rationale

While it’s important for the daughter to understand the progressive nature of Alzheimer’s disease, this understanding alone does not determine when to start medication. The decision to start medication should be based on a comprehensive evaluation of the patient’s condition and the potential benefits and risks of the medication.

A. Consume with milk or antacids to prevent gastrointestinal irritation. B. Protect your skin from sunlight while on this medication. C. Enhance gastrointestinal absorption by taking with orange juice. D. Return to the clinic weekly for serum drug level checks.

Correct Answer is B

Explanation

Choice A rationale

Tetracycline should not be consumed with milk or antacids. These substances contain calcium, which can bind to tetracycline in the stomach and reduce its absorption and effectiveness.

Choice B rationale

Tetracycline can make the skin more sensitive to sunlight, increasing the risk of sunburn. Patients should be advised to protect their skin from sunlight while taking this medication.

Choice C rationale

Taking tetracycline with orange juice is not recommended. Citrus fruits and juices contain calcium, which can bind to tetracycline in the stomach and reduce its absorption and effectiveness.

Choice D rationale

Returning to the clinic weekly for serum drug level checks is not typically necessary for patients taking tetracycline. While regular follow-up appointments may be needed to monitor the patient’s response to treatment, weekly serum drug level checks are not a standard part of tetracycline therapy.
