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

Choice A rationale
Smoking cigarettes can exacerbate the symptoms of Raynaud’s disease by causing further constriction of the blood vessels. Therefore, a patient who continues to smoke cigarettes may need further education about the management of Raynaud’s disease.
Choice B rationale
Eating bananas twice a day is not typically a concern for patients with Raynaud’s disease.
Choice C rationale
Wearing mittens outside, especially in cold weather, is a recommended strategy for managing Raynaud’s disease. It can help to prevent episodes of Raynaud’s by keeping the hands warm and reducing exposure to cold temperatures.
Choice D rationale
Taking calcium channel blockers is a common treatment for Raynaud’s disease. These medications help to relax and open up the small blood vessels in the hands and feet, reducing the severity and frequency of Raynaud’s episodes.

Choice A rationale
Bradycardia, palpitations, confusion, and truncal rash are not typically associated with septic shock. Septic shock is a severe infection that occurs when bacteria enter the bloodstream. It can cause organs to fail and can lead to death.
Choice B rationale
Severe respiratory distress, jugular venous distention, and chest pain are more commonly associated with conditions like heart failure or pulmonary embolism, not septic shock.
Choice C rationale
Low blood pressure and tachycardia are common symptoms of septic shock. This happens because the body’s response to the infection causes blood vessels to dilate, which can lower blood pressure. The heart rate often increases (tachycardia) in an attempt to maintain blood flow to the organs.
Choice D rationale
Reduced cardiac output, increased systemic vascular resistance, and a moist cough are not typical symptoms of septic shock. These symptoms are more commonly associated with conditions like heart failure.
