The nurse is providing care for a client diagnosed with cardiovascular disease and hypertension who is complaining of chest pain. Which medication should the nurse administer?

Choice A reason: Performing meditation every day will not be the most important information that the nurse should stress first. Meditation is a practice that involves focusing the mind on a particular object, thought, or activity, and can help reduce stress, anxiety, and blood pressure. However, meditation alone is not enough to prevent or treat coronary artery disease, which is a condition where the arteries that supply blood to the heart become narrowed or blocked by plaque. The nurse should advise the client to practice meditation as a complementary therapy, but not as the primary intervention.

Choice B reason: It is important to look into a smoking cessation program is the most important information that the nurse should stress first. Smoking is a major risk factor for coronary artery disease, as it damages the lining of the arteries, increases the buildup of plaque, reduces the oxygen in the blood, and raises the blood pressure and heart rate. Smoking can also worsen the symptoms and complications of coronary artery disease, such as chest pain, shortness of breath, or heart attack. The nurse should urge the client to quit smoking as soon as possible, and provide them with resources and support to help them achieve this goal.

Choice C reason: It is important to take a fish oil capsule daily is not the most important information that the nurse should stress first. Fish oil is a source of omega-3 fatty acids, which are beneficial for the heart and blood vessels, as they can lower the triglycerides, reduce inflammation, and prevent blood clots. However, fish oil alone is not enough to prevent or treat coronary artery disease, which is a condition where the arteries that supply blood to the heart become narrowed or blocked by plaque. The nurse should recommend the client to take fish oil as a supplement, but not as the main treatment.

Choice D reason: You will not be able to eat meat or have other fats in your diet is not the most important information that the nurse should stress first. A healthy diet is essential for preventing and managing coronary artery disease, as it can help lower the cholesterol, blood pressure, and weight, and improve the blood flow and oxygen to the heart. However, a healthy diet does not mean that the client has to avoid all meat or fats, as some of them can be beneficial for the heart, such as lean meat, poultry, fish, nuts, seeds, or olive oil. The nurse should educate the client to limit the intake of saturated and trans fats, which are found in red meat, butter, cheese, pastries, or fried foods, and to choose more fruits, vegetables, whole grains, and low-fat dairy products.

Choice A reason: The international normalized ratio (INR) is a measure of the blood's ability to clot. It is not affected by ferrous sulfate therapy, which is used to treat iron deficiency anemia. The normal range of INR is 0.8 to 1.2 seconds.

Choice B reason: Hemoglobin is the protein in red blood cells that carries oxygen. It is the main indicator of anemia and the response to iron therapy. The normal range of hemoglobin for adults is 12 to 18 g/dL. A hemoglobin level of 14 g/dL suggests that the patient's anemia has improved with ferrous sulfate therapy.

Choice C reason: Serum iron is the amount of iron in the blood. It is not a reliable indicator of anemia or iron therapy, as it can fluctuate with dietary intake, infection, inflammation, and other factors. The normal range of serum iron for adults is 50 to 170 mcg/dL.

Choice D reason: Platelet count is the number of platelets in the blood. Platelets are involved in blood clotting and wound healing. They are not affected by ferrous sulfate therapy, which is used to treat iron deficiency anemia. The normal range of platelet count for adults is 150,000 to 450,000/mm3.
