When preparing a patient for a cardiac catheterization and coronary angiogram, which piece of information about the patient is crucial for the nurse to relay to the healthcare provider prior to the procedure?

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
Administering Lasix (a diuretic) would not be the most immediate intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin. Lasix is used to treat fluid retention (edema) and swelling caused by congestive heart failure, liver disease, kidney disease, and other medical conditions. It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine.
Choice B rationale
The most important nursing intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin would be to increase myocardial oxygenation. This can be achieved by administering supplemental oxygen and ensuring the patient is in a position that maximizes respiratory efficiency (such as semi-Fowler’s position). This intervention addresses the immediate life-threatening situation of myocardial ischemia.
Choice C rationale
Obtaining one hour of echocardiogram readings would not be the most immediate intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin. While an echocardiogram can provide valuable information about the structure and function of the heart, it is not the first step in managing acute chest pain.
Choice D rationale
Decreasing the patient’s anxiety is an important aspect of care, but it is not the most immediate intervention for a patient experiencing increased chest pain after taking sublingual nitroglycerin. The priority is to address the physical cause of the chest pain.
