Which medication, when noted in a patient’s history, will diminish the effects of Warfarin (Coumadin)?

Iron supplement for anemia.

Furosemide (Lasix) for fluid retention.

Simvastatin (Zocor) for cholesterol control.

Yaz (drospirenone/estradiol) as an oral contraceptive.

Answer and Explanation

The Correct Answer is D

Choice A rationale
Iron supplements for anemia do not typically interact with warfarin (Coumadin). Iron is a mineral that is essential for the production of red blood cells, and supplements are often prescribed to patients with anemia to increase their iron levels. While it’s important for healthcare providers to be aware of all medications and supplements a patient is taking, iron supplements are not known to diminish the effects of warfarin.
Choice B rationale
Furosemide (Lasix) is a diuretic medication used to treat fluid retention. It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine. While furosemide can interact with other medications, it is not known to diminish the effects of warfarin.
Choice C rationale
Simvastatin (Zocor) is a medication used to control cholesterol levels. It works by slowing the production of cholesterol in the body to decrease the amount of cholesterol that may build up on the walls of the arteries and block blood flow to the heart, brain, and other parts of the body. Simvastatin does not typically interact with warfarin to diminish its effects.
Choice D rationale
Yaz (drospirenone/estradiol) is an oral contraceptive that contains estrogen. Estrogen can potentially increase the effects of warfarin, leading to an increased risk of bleeding. Therefore, if a patient taking warfarin also takes Yaz, it could potentially diminish the effects of warfarin, making it less effective. This is why it’s important for healthcare providers to be aware of all medications a patient is taking, including oral contraceptives.

Correct Answer is D

Explanation

Choice A rationale
Aortic regurgitation is a condition where the aortic valve doesn’t close tightly, causing blood to leak back into the left ventricle. This condition can lead to left heart failure but is not typically associated with right heart failure.
Choice B rationale
Mitral regurgitation is a disorder in which the mitral valve on the left side of the heart does not close properly. This condition can lead to left heart failure but is not typically associated with right heart failure.
Choice C rationale
Aortic stenosis is a narrowing of the aortic valve opening. This condition can lead to left heart failure but is not typically associated with right heart failure.
Choice D rationale
Tricuspid regurgitation is a disorder in which the heart’s tricuspid valve does not close properly, causing blood to flow backward into the right atrium. This condition can lead to right heart failure, especially when associated with pulmonary hypertension.

A. Palpable liver edge 2 cm below the ribs on the right side. B. Serum potassium level of 3.0 mEq/L after 1 week of therapy. C. Weight increase from 120 pounds to 122 pounds over 3 days. D. Presence of 1+ to 2+ edema in the feet and ankles.

Correct Answer is B

Explanation

Choice A rationale
While palpating the liver edge can provide information about liver health and potential fluid accumulation, it is not typically a priority assessment for a patient taking Digoxin (Lanoxin), Furosemide (Lasix), and Captopril.
Choice B rationale
A serum potassium level of 3.0 mEq/L is low (hypokalemia). This is a critical finding because both Digoxin and Furosemide can cause hypokalemia. Hypokalemia increases the risk of digoxin toxicity, which can lead to serious cardiac arrhythmias.
Choice C rationale
While weight gain may indicate worsening heart failure, a gain of 2 pounds over 3 days is not typically considered significant. However, any sudden or unexplained weight gain should be reported to the healthcare provider.
Choice D rationale
Presence of 1+ to 2+ edema in the feet and ankles could indicate worsening heart failure, but it is not as immediately concerning as hypokalemia in a patient taking Digoxin and Furosemide.
