A 73-year-old patient has increased pulmonary pressure resulting in right heart failure. What could be a potential cause for the right heart to fail?

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.

Choice A rationale
While obesity can contribute to hypertension and other cardiovascular diseases, it is not a contraindication for the use of propranolol. Weight management would be part of the overall treatment plan for hypertension, but it would not prevent the use of this medication.
Choice B rationale
Age is not a contraindication for the use of propranolol. While older adults may be more susceptible to certain side effects of the medication, age alone would not prevent a patient from taking propranolol.
Choice C rationale
Diabetes is a contraindication for the use of propranolol. Propranolol is a non-selective beta- blocker, which can mask symptoms of hypoglycemia, a common condition in people with diabetes. Therefore, it’s generally not recommended for people with diabetes.
Choice D rationale
Race is not a contraindication for the use of propranolol. While there are some differences in how people of different races may respond to certain medications, race alone would not prevent a patient from taking propranolol.
