A nurse is providing patient education for reducing the risk of coronary artery disease. Which of the following statements should the nurse make? (Select all that apply.)

Aim to keep your HDL cholesterol as low as possible

Controlling your diabetes is an important factor

Exercising and achieving your goal weight are recommended

Increase saturated fat intake and limit unsaturated fats

It is important to keep your blood pressure within normal limits

Answer and Explanation

Correct Answer : B,C,E

A) Aim to keep your HDL cholesterol as low as possible:
High-density lipoprotein (HDL) cholesterol is often referred to as "good" cholesterol because it helps remove excess cholesterol from the bloodstream, thereby reducing the risk of atherosclerosis and coronary artery disease. The goal should be to raise HDL cholesterol levels, not lower them. Higher levels of HDL are associated with a lower risk of heart disease.

B) Controlling your diabetes is an important factor:
Diabetes is a major risk factor for coronary artery disease (CAD). Uncontrolled blood sugar levels can lead to damage of the blood vessels, increase the risk of atherosclerosis, and raise the likelihood of heart disease. Proper management of diabetes through diet, medication, and lifestyle changes is essential to reduce the risk of CAD.

C) Exercising and achieving your goal weight are recommended:
Regular exercise and maintaining a healthy weight are crucial for reducing the risk of coronary artery disease. Exercise helps improve cardiovascular health, lowers blood pressure, increases HDL cholesterol, and helps control body weight and blood sugar. Achieving and maintaining a healthy weight reduces the strain on the heart and lowers the risk of developing CAD.

D) Increase saturated fat intake and limit unsaturated fats:
Saturated fats can raise low-density lipoprotein (LDL) cholesterol, also known as "bad" cholesterol, which contributes to plaque buildup in the arteries and increases the risk of heart disease. Unsaturated fats, found in foods like olive oil, avocados, and fatty fish, are healthier and can help reduce cholesterol levels and improve heart health. The goal should be to limit saturated fats and increase the intake of unsaturated fats.

E) It is important to keep your blood pressure within normal limits:
High blood pressure is a significant risk factor for coronary artery disease. It can lead to the hardening and narrowing of the arteries, increasing the risk of heart attacks, strokes, and other cardiovascular events. Keeping blood pressure within normal limits through lifestyle changes, such as reducing salt intake, managing stress, exercising, and taking medications if needed, is essential for heart health.

Correct Answer is A

Explanation

A) Pernicious anemia:
Vitamin B12 injections are most commonly used to treat pernicious anemia, which is caused by a deficiency in vitamin B12 due to an inability to absorb the vitamin from the gastrointestinal tract. This condition is often associated with a lack of intrinsic factor, a protein required for vitamin B12 absorption. As a result, the body cannot make enough healthy red blood cells, leading to anemia. The treatment of pernicious anemia typically involves lifelong vitamin B12 injections, making this the correct answer.

B) Hemolytic anemia:
It is not typically treated with vitamin B12 injections. Instead, hemolytic anemia may require treatments that address the underlying cause of red blood cell destruction, such as corticosteroids, immunosuppressive therapy, or splenectomy, depending on the type of hemolysis. Therefore, vitamin B12 would not be the primary treatment for this type of anemia.

C) Iron deficiency anemia:
It is typically treated with iron supplements, either orally or intravenously, rather than vitamin B12. While both conditions cause anemia, the treatment for iron deficiency anemia is not vitamin B12, so this is not the correct choice.

D) Aplastic anemia:
This condition is usually treated with treatments such as bone marrow stimulants, blood transfusions, or bone marrow transplantation, rather than vitamin B12. Vitamin B12 supplementation would not be indicated for the treatment of aplastic anemia.

A. Obtaining a primary and secondary tubing set B. Ensuring another licensed personnel is available C. Obtaining 0.9% normal saline solution D. Checking ABO and Rh status of the donor and recipient

Correct Answer is B

Explanation

A) Obtaining a primary and secondary tubing set:
The primary tubing is used for the intravenous access, and the secondary tubing is attached for administering the blood product. This ensures that the blood transfusion will be delivered effectively, and it is a standard practice to use proper IV tubing for blood products to avoid contamination or complications.

B) Ensuring another licensed personnel is available:
. While it is required that two licensed healthcare professionals verify the blood product before starting the transfusion, this action itself is not contraindicated, it is required. Both individuals should independently check the patient's identification, blood type, and the matching of the blood product before administration. Therefore, the answer to the question should not be about ensuring availability of licensed personnel as this is actually a required safety measure, not contraindicated. The actual contraindications involve actions like using inappropriate fluids for transfusion or mismatching blood.

C) Obtaining 0.9% normal saline solution:
This is appropriate and necessary when preparing for a blood transfusion. Normal saline (0.9%) is the only compatible solution that should be used to flush the IV line before and after the transfusion or to prime the blood tubing. Other solutions, such as lactated Ringer's, can cause clotting when mixed with blood, making saline the only appropriate choice.

D) Checking ABO and Rh status of the donor and recipient:
This is essential and mandatory before administering a blood transfusion. It is critical to ensure that the ABO blood group and Rh factor of the donor and recipient are compatible to prevent hemolytic reactions. This compatibility check must be done every time before administering a transfusion, and it is an integral part of ensuring patient safety.
